Review: Khaba for iPhone and iPad

Khaba by the Swedish Hello There was released last year, but I only played it recently. I was surprised by it because it has high production values, including full voice acting, but it is relatively unknown.

I downloaded the game while it was free for a couple of days. I promptly tweeted about that; make sure to follow me to not miss these opportunities!

I really enjoy the overall atmosphere and the mechanics of the puzzles. Unfortunately, it looks like most of the development effort went into the aesthetics and too little on usability testing.

The premises are a bit of a stereotypical B-movie plot, which doesn't make them less appealing. You are an explorer trapped in a pyramid, and need to use a beam of light to advance through it. Everything is presented in a top-down perspective view, rendered in full 3D, though the 3D is only for presentation because the puzzles are strictly bidimensional.

To control the beam you use some poles which, when struck by the light, can deflect it in any direction. There are also mirrors on the walls, which are fixed in place and can only be used to reflect the beam at a fixed angle.

In the image above you see two types of poles: the one in the center can only be rotated, while the other two (the most common) can both be rotated and moved around. There is also a third type which splits the beam in two.

When moving poles around, you are constrained by the environment. E.g. if there is a closed door, you can't move a pole through it unless you first open the door.

After warming up for a few levels, the game introduces its main mechanic: when the beam hits the blue orb, you can tap the button on the bottom left and enable an "alternate plane" of light. That starts a beam of blue light, and transforms the screen from this...

... to this.

There are two things to note in that image. The first is that, contrary to common physics, the blue beam cannot cross the yellow beam. So in the above example, to let the blue beam reach the left of the screen you'll need to make the yellow beam hit the orb from the other side.

The other thing to note is that when the alternate plane is enabled, three green scarabs appear. Your secondary objective is to touch all three scarabs at the same time with the blue light. When you do that, you'll learn more about the pharaoh's story, and if you do it for all levels you'll get a different ending at the end of the game.

As the game progresses, the levels become more and more complicated, containing glass doors that can only be crossed by light of the same color, and lots of switches to trigger. It's important to note that switches are of two different kinds: ones that need to be kept lit to keep the door open, and ones that need to be hit only once to permanently open the door. That's crucial to allow progression through a level.

There are 28 levels in total, but if you're thinking that's not many, think again: completing a single level requires many steps and takes several minutes. If you go for all three scarabs (which you definitely should), even more.

Having long levels is great, but in this case it's also a problem because your progress isn't saved: every time you launch the game, it starts again from the intro, and you have to go through the level selection menu, restarting the level from the beginning. This is an incredible oversight for a mobile game, and extremely annoying. Essentially, when you start playing, you'd better make sure to have enough time to finish a level.

But as annoying as that might be, it pales in comparison to how frustrating the controls are. Directing the beams often requires extreme precision, which is very hard to achieve given how the controls have been implemented.

First of all, every time you touch a pole the direction of the bem is reset to the position of your finger, which makes it impossible to do incremental adjustments. Second, as soon as you lift the finger, more often than not the beam direction will be altered, messing up your alignment and forcing you to do it again.

I'll not even mention how often you move a pole instead of rotating it, or the other way around, or you pick the wrong pole when there are two next to each other. Those are minor issues compared to the one above.

And all this is while playing on iPad Mini. I can imagine that the game must be totally unplayable on iPhone.

This is a huge issue. Such poor controls wouldn't have been adequate for an early prototype, let alone a published game.Since I'm not the only one to complain about this, I would have expected the developers to hurry to fix it. Instead, the only update in the past six months was just to add more languages.

I like this game, I really do; but I can't recommend spending money on it unless the controls are improved.

Review: RGB Express for iPhone and iPad

RGB Express is captivating from the beginning. It has cute graphics and animations, an everyday theme that can be related with, and it just feels light and joyful.

The Finnish-German developer Bad Crane has clearly been targeting the young and casual audience with this game, and I think they've been quite successful. The mechanics are deeper than a simple casual game would require, but expert puzzlers will need a lot of perseverance before getting to the interesting parts.

You control some trucks on a city map. Your objective is to collect some colored boxes and bring them to their destination. You do that by drawing the paths that each truck should follow; when you are satisfied with the paths, you tap the Play button to check if the solution works or not.

The paths can cross, or touch in a corner, but you cannot pass through the same straight section of road more than once. This limitation implies that you cannot pass in front of a house without carrying a box addressed to it: the game immediately stops in that case, because it would not be possible to pass in front of the house a second time to deliver the package. Actually, as Federico Prat Villar showed me, this isn't entirely true, because when the house is in front of a 3-way junction you would be able to pass in front of it twice. But the game doesn't allow you anyway.

Also, there is a timing element because the trucks can crash into one another, so you have to be careful to not make two paths cross at the wrong moment.

The trucks can pick up more than one box at the same time, but no more than three. That's an important limitation in a few cases, where you might like to pick up four or five boxes at the same time and deliver them later.

The colored trucks can only deliver boxes to houses of their color, but they can pick up boxes of any color. There are also white trucks which can deliver boxes of any color. In that case, your load acts as a stack, so the last box picked up is the first to be delivered. You cannot pick a red and a green box and then pass in front of the red house: you need to deliver the green first.

Another element is movable bridges. When they are open, the trucks cannot pass over them. They are operated by buttons of the same color, found in other parts of the puzzle; sometimes there are two buttons, one to open and one to close.

The most interesting element is drop points at intersections. You can activate them while designing the solution. When they are active, the first truck that passes over them drops its top box, and the second truck picks it up again (of course, the game rules imply that no more than two trucks can pass through the same intersection). This allows you to exchange boxes of different colors.

The game sports 240 levels, but my main criticism is that most of the first half of them are nothing short of trivial, really too simple to be interesting.

There's nothing wrong in being easy, but even then, there should be some challenge, something that makes the player feel smart for finding the solution. When there is no perception of challenge, there is also no satisfaction for solving a puzzle. I didn't feel challenged at the beginning, because in many cases I could literally draw the first paths that I could think of and they would just work. It felt more like grinding than thinking. I kept playing, confident that eventually the puzzles would become more stimulating, but I would have preferred if the game contained half the levels but of higher average quality and with a better difficulty curve.

The first impact with the game has been carefully polished; I was impressed by details like the way how the clouds move in the city selection screen. I think some corners have been cut with the in-game animations, in particular when the trucks take a turn, which feels a bit jarring. I think there's also a bug in the animation of the bridges opening or closing. It doesn't look right.

The user interface is good, but it's intrinsically complicated because of the many paths that you might have to draw. It requires some precision so I found it a bit too difficult to control on a small screen. On iPad Mini it's a lot better. It still doesn't feel completely intuitive, and correcting paths often seems to require more taps than should be needed.

A very nice touch is that while you draw the path for one truck, the game shows how the other trucks will be moving along the paths you have already drawn. This makes it a lot easier to check that the timing is right and avoid crashes.

Overall, this game is entertainment for the whole family so it's an easy recommendation. Be warned that it might require some patience before it becomes really rewarding.

Review: The Weaver for iPhone and iPad

The other day I noticed the polished icon of The Weaver among the new releases, and I was thrilled to see that it was developed by the Portuguese Pyrosphere.

Pyrosphere might not be as well known as other big names in the industry, but I think it is one of the best developers of puzzle games in the world. I've reviewed other great games by them in the past: Lazors, Chess Light, and Bloom Box.

I wasn't disappointed; The Weaver is excellent, and I couldn't stop playing until I had almost finished it.

There is a remarkable number of ribbon-weaving puzzle games: clearly it has something that appeals to our playful side. I reviewed TAPES just last week, but the obvious precursor of this game is Strata  In my review, I criticized Strata because it was possible to solve all its puzzles using a mechanical procedure. I'm glad to say that while The Weaver looks remarkably similar at first glance, it doesn't have a similar weakness.

The play area consists of a few colored ribbons entering from above. Their paths are blocked by colored squares; your objective is to route the ribbons in such a way that each ribbon exits the screen passing over a square of the same color.

One move consists of tapping one of the intersections. That folds the two ribbons passing there, making them go in the opposite direction. For example here my first move is on the blue and green ribbons, which produces this result:

The blue ribbon was able to exit the screen because it's now passing over a blue square.

Note that the fold only happens along a vertical line: this means that the ribbons always enter from the top, change direction a number of times, and exit from the bottom. You cannot send a ribbon back to the top. This fact can be used for many logic deductions.
For example in the position above if I let the green ribbon go over the red one, there's no way to make it climb back to the green exit. Therefore, I must put a fold on the red/green intersection, like this:

And with a final move, the puzzle is solved.

In this case the solution was unique, but in general the puzzles can be solved in multiple ways. The number of stars you get depends on how many folds you did. Note that you can do as many moves as you want while solving the puzzle; the only thing that matters is how many folds are left at the end.

I haven't verified this, but knowing the quality of Pyrosphere's puzzles I'm pretty sure that every puzzle has only one 3-star solution.

As you progress through the game, there are no additional mechanics: the only things that change are the sizes of the puzzles (which aren't necessarily square), and the number of colors shown on each exit. Interestingly, having more options on each exit actually makes the puzzles harder, not easier, because it adds uncertainty, and the optimal solution is only one.

But there are logic deductions that can be applied to this additional uncertainty, too. For example in the above puzzle there is only one purple ribbon, which must exit from the bottom left. All the other purple exits are just decoys that can be ignored.

Things get more and more complicated and in the later puzzles it becomes difficult to solve the puzzles solely through logic; like in Lazors, you have to also rely on intuition and experimentation.

Often times, you can reach a suboptimal solution rather quickly but then have to spend a lot more time improving it if you want to get three stars.

One thing to note is that, unlike in other games, in this one the ribbon metaphor wouldn't be really needed. Instead of ribbons, you could have had light beams and vertical mirrors: the effect on the puzzle mechanics would have been identical.

However, it wouldn't have been nearly as fun: the use of ribbons is a major element in the appeal of this game. The way how the animate as you make your moves is relaxing and almost hypnotic. I think this game is a perfect application of a game design principle well explained by Ted Brown in an article I read some time ago:

Give [your players] a clear goal, give them a simple way to achieve that goal, give them fantastic feedback, and stop there. It might be enough.

I'd also like to mention that while I've been growing used to recent games running poorly on my old 4th Gen iPod Touch, this one runs beautifully. So don't waste any more time and go download this little treasure.

Review: TAPES for iPhone and iPad

I like discovering good puzzle games that might be overlooked by most people. TAPES by Yohei Sato, a brilliant game with a user interface mostly in Japanese, is certainly one of them.
People that follow me on Twitter knew it first; now let's talk about this little gem in more detail.

It's no mystery that I like path finding puzzles. BlockPath, for example, made into my list of the 10 best puzzle games of 2013. I have been even developing one of my own in the past months—though that project is currently on hold.

I thought I had seen everything about this concept. I was amazed, then, to be totally surprised by the rules of TAPES.

The game begins in the easiest way. Start from the dot and fill the grid. Piece of cake.

But soon, something different happens: unlike most other similar puzzles, the paths can instersect. So from here...

... you need to do this.

There is a subtlety in the rules: two paths can go over the same cell only if they pass straight through it, crossing each other. When a path makes a turn on a cell, no other pass can use that cell. So in the above case, it wouldn't be possible to go down with the green path and right with the blue one.

The other surprise is that a path can intersect itself, and this is often required to solve the puzzles. Look at this one for example:

there's no way you would be able to fill the grid without going through the same cell twice. Allowing that, the solution is still unique.

Did you notice that there is a number inside the dots? That's the final brilliant rule. The number indicates over how many more cells the path must pass before filling the board; not one more and not one less. Look at this for example:

It would be trivial to fill the grid doing an obvious path, but you'd end in this position:

That's not a solution because you still have 4 more cells to go over. To use those extra cells, you need to make the path intersect itself.

These rules work perfectly to produce delightfully enjoyable puzzles; 108 of them, in the current version. Most of them are not too hard, but they are very fun, and I think that a major reason for that is because the solutions are simply beautiful to look at; I've talked about "paths" so far, but as you have seen, the game represents them as ribbons, which is a perfect metaphor for the rules.

When you solve a puzzle it scrolls away automatically, but you can pull down the screen to look again at the pattern you just created; something that I've done more than once. I think it would have been more rewarding to give full relevance to the solutions and let the player move on when they want.

The puzzles can be surprisingly challenging to solve. The rules controlling the intersections require a different approach from many similar concepts. You can also use a good amount of logic: for example the cells where a path must end are often obvious, and you can use reasonings about parity to rule out certain combinations.

My main regret with this game is that the user interface is not as good as it could be. Drawing the paths is not very smooth, because if you don't move your finger very precisely it's easy to leave the dots behind. Additionally, I would have liked to simply tap a cell in the middle of a path to erase the rest of it and start drawing a new one. Instead, the only way to erase a path is by drawing it backwards, which can get tedious when the path is long.

But those are minor inconveniences when compared to the fun I had. Highly recommended.

Review: Go To Gold for iPhone and iPad

What drew me to Go To Gold by Timur Nigmetzianov was its very nice graphics. I didn't expect that the puzzles would be even better.

I downloaded this game while it was free for a day, and promptly tweeted about it. Make sure to follow me to not lose these opportunities!

Go To Gold is based on the classic Sokoban puzzle, so it doesn't need many explanations. It has however some aces up its sleeve in terms of originality.

But first, the basic rules, in case you don't know them. Your goal is to move some blocks to the indicated positions on the board. You can move the blocks only by pushing them, not pulling; and you can push only one block at a time.

The first level helps getting acquainted with the mechanics and controls, but it also shows what this game is not: it is not one of those games that hold the player by their hand with an endless series of trivial puzzles at the beginning, fearful to scare away the less confident players.

No, here we start with a puzzle which, while very easy, still requires a fair amount of work.

And then the second level already requires a lot more work. At this point, I was already hooked.

What I like about the selection of puzzles in this game is that they are compact, don't contain many objects, but they are very satisfying to play. There aren't many levels in total—they are 64 divided in four groups of 16—but each one provides its own challenge, and after playing the game for a week I'm still fighting through it. Most of the levels are requiring me multiple sittings, because I just can't figure them out. The a-ha! moments when I finally see how it's possible to navigate around the seemingly impossible position are some of the best ones I've experienced in a while.

I found logic to be very useful in approaching these puzzles. The tight spaces mean that there is very little freedom of movement, and in most cases even getting a block on its goal and out of the way doesn't make things any easier. It helps to think backwards from the goal position: there is often only one way to push a block onto a goal tile, which gives valuable hints on what needs to be done before.

I would be happy just having this kind of puzzles for the whole game, because they are that good. But the author has done more: there are four different settings, with slightly different rules.

In the second group, the blocks are colored, and each one needs to go to the goal of the same color.

In the third group, there are no clear goal positions. Instead, your objective is to use some mirrors to reflect a beam of light and make it hit a certain block.

In the last group, there are colored walls which need to be lowered by pushing blocks over the corresponding colored buttons.

Also, extra points for making all levels playable from the start. No frustration if you get stuck on a level: just try another one.

As can be seen from the screenshots, the graphics are very well done. The animations are very good too, and the music is on the same level. This is really an excellent presentation, possibly the best I've seen for a Sokoban game.

My initial reaction to the controls was that your man moves a bit too slow, and it's tiring to have to swipe for every step.
In Sokoban puzzles, how you walk around isn't really important, the only thing that matters is which sides of the blocks you can reach and push. Therefore, some games have implemented interfaces where you just tap where you want to go and the character moves automatically.
However, I must say that the controls grew on me after a while. Swiping requires less precision, so it's easier to play one handed. Also, the game intelligently queues every swipe you make, so you can issue multiple commands quickly and then wait for the character to complete them. I just wish that he moved a bit faster.

I consider this one of the best puzzles games of the year and I strongly recommend it for the quality of its levels.

Review: Watercolors for iPhone and iPad

I'm glad to host another review by Roberto Canogar. Hopefully more will follow!

Watercolors, developed by ADONIS SOFTWARE from Romania, is a Free game that was released a couple of months ago. It reached the #1 position in the Education category in 77 countries, and in the Puzzle category in 13 countries (including big countries like USA, UK and Canada to name a few).

At the moment the number of players in Game Center is close to one million. So, we can say it has been a successful game. But, is it a good puzzle game? What are the reasons behind its success? Lets try to answer these questions.

Watercolors is a game about mixing colors and also about drawing. I think that games that let you draw with colors have an immediate gratification. All of us secretly would love to know how to paint.

This game lets you mix colors effortlessly and with a clear objective, something that in real life is much more smudgy. Also, this theme seems to be a good match for the Education category as the numbers above suggest. Other puzzles inspired by these ideas come to mind: Flow Free and especially Puzzle Restorer.

Well, now let's talk about the game mechanics of Watercolors. This game is about mixing three elementary colors: blue, red and yellow. So first we have to get very familiar on how they mix.

Bellow we see a detail of Level 1 and Level 2. The first one (on the left) shows us that we have to drag colors from filled circles to glowing and hollow circles of the same color by following a path of connected white circles.

The second level (on the right) tells us that we can combine colors by dragging a color on top of another one. So we can make a first stroke from the yellow filled circle to the empty spot indicated by the arrow, and then we can make a second stroke from the blue filled circle all the way to the bottom because as we pass the yellow circle the stroke changes to green (Blue+Yellow=Green).

But level 2 can be drawn with one stroke! We start it from the yellow filled circle and we go to the blue filled circle which will change color to green (see left). Then without lifting the finger we go all the way to the hollow green circle (see right).

By solving levels with the minimum number of strokes we gain 3 stars, and for suboptimal solutions we receive 2, 1 or even 0 stars. I enjoy finding the minimum number of moves.

It is quite rewarding to do all the steps that are involved in the resolution of a puzzle. First we have to look at the picture, recognizing the elementary colors and the compound colors and their relative positions. Second we plan our strokes, and third we execute them. Many times the strokes are long and go back and forth the screen, and change several times of color as they pass through different solid circles. Like the next one, that can be solved with one long stroke.

But then, the next level is essentially the same, even the same colors. OK, instead of Snakes (look at the title of the levels) we have to draw a Fancy Glass, but that's it.

The next one, level 10, is almost the same again. This happens often. Level 5 and 6 are equally similar. Then level 11 and 12 are also the same. I often think "OK, I've got it... don't bore me, please!". But this repetition is done purposely, and it probably makes more good than harm. I don't like repeating puzzles, but there must be a lot of people who prefer it this way.

Apart from the tiresome learning curve I would say that the level design is dull. One is rarely surprised by a cleverly designed level. Sporadically, one gets a very tough one (e.g. level 17 of the Three-Colors pack). There is a Pro-Pack which is challenging, but the levels look messy and chaotic. The result is that the levels are not enticing at all.

To add more variety there is a time mode, where we have to solve as many levels as possible in a specific amount of time. But the selection of levels presented in the time mode seems like a random selection of levels from the standard mode. So we may start with a trivial level, followed by a very complex one. There is so much luck involved in the random selection that I don't enjoy it, frankly.

Anyway, I have to give a thumbs up for the presentation of the game. It is mostly white, very clean, nothing groundbreaking but simple and effective. The omnipresent white is a perfect backdrop for all the colorful strokes that you do. Then the user interface is quite good in general, but there are two things I dislike. First, the undo button doesn't discount the number of strokes, so if one wants to get three stars it is useless.

The second problem is that the figures that you paint resemble objects (Snakes, Fancy Glass), so they tend to have many connected circles very close together, much more than otherwise required. So it is very easy to paint a wrong circle, which often implies starting over. This is more of a problem on the iPhone, and it is a big problem when you are under time pressure. In this sense the Grid-Pack worked better for me, because in this pack the connections are made through a grid so it very easy to follow a path.

So, in summary, this is mostly an easy game, and thus very approachable. And even after all my criticism, playing it is an enjoyable experience. Probably these are two of the reasons of its success. But as a puzzle game it could have been better.

Review: Game About Squares for iPhone and iPad

Game About Squares by Andrey Shevchuk is, sadly, both an exceptionally good puzzle game, and another story of shameless cloning on the App Store. There are actually so many clones that it's almost impossible to find the official version using iTunes, so make sure to use the link above.

Born as a HTML5 app, it was online for some time without gaining much visibility. Interestingly, like 2048 before it, it seems to have become viral after it appeared on Hacker News. Immediately after that, after the week or so needed to pass Apple's review, the App Store was flooded with clones.

And for good reason! This is one of those rare cases of an idea brilliant in its simplicity, but at the same time capable of deep complexity.
Your goal is to bring each square over the dot of the same color. To move the squares, you just tap them, and they move by one step in the direction of the arrow.

Of course the squares aren't always finely aligned like in the above case, so you'll have to nudge them in the right position, by pushing them with other squares.

To add more dynamicity to the movement of the squares, the board can also contain some dark arrows. When a square goes over one of those arrows, its movement direction changes. This is somewhat reminiscent of another great game released this year, Perfect Paths.

And that's all! There are no other mechanics added to the mix.

The game contains 36 puzzles, and be assured that it will keep your interest high until the end. The first few puzzles wonderfully teach the mechanics without need for any tutorial, then the puzzles start to get intriguingly simple and complex at the same time.
This is some of the best level design I've ever seen, and I think it is the final proof that to make a puzzle game varied you don't need to add a lot of different mechanics, but you just need good mechanics that can be pushed to their limits in different ways.

For example I got stuck for a while on this puzzle. The more I thought about it, the more it seemed to be impossible, until it eventually clicked. Think outside the box.

Inbetween the levels the author has added some jokes which made me smile a few times. Other people hated them.YMMV. Puzzled by the flowery dots in the above screenshot? You'll have to play the game to understand what's going on.

The user interface is minimalist and works perfectly. The only minor issue I had was that the app is simply a wrapper of the HTML5 game done using PhoneGap, so the frame rate is poor on older devices. But this isn't certainly the kind of game that requires 60fps to be enjoyed.

This is without a doubt one of the best puzzle games of 2014, and its author is smart and witty. I hope to see more from him in the near future.

Review: iON Bond for iPhone and iPad

Apologies for the infrequent updates. I've been tied up by family matters and by contract work on Puzzlium. So many great puzzle games have been released in the past few months! Even if I don't have time to write full reviews, I always talk about the best games on Twitter, so make sure to follow me.
 
It's rare for me to like puzzle games that have a real time element, but iON Bond by Stewart Hogarth caught my interest, probably because the timing is very relaxed and doesn't require deadly accuracy nor lightning fast reflexes.

Those ?????? you can see above intrigued me enough that I made it a point of honor to see what was hiding there before writing this review. I succeeded, which should be good proof that the game is interesting enough, and the difficulty properly balanced.

The premises of the game are pretty simple. There are some particles on the screen, which you can't control directly, but only through bonds that you can form with other particles.

You use your finger to draw bonds. When you connect two particles, they start to interact depending on their sign. Opposite signs attract, equal signs repel. The particles have lots of intertia and they move rather slowly, so you have time to form complex interactions between multiple particles. You can also break the bonds you formed by swiping through them; this is something that you'll need to do often as the game progresses.

When two particles collide, they leave traces reminiscent of the ones we are used to see when reading about particle accelerators. Your primary goal is to make all particles collide. The secondary goal is to collect all the small grey dots (which represent neutrinos).

The particles can have different colors; only particles of the same color will react during a collision, particles of different colors will just stop.

Charged particles are the most common, but there are also neutral particles like the red ones below. They don't interact with other particles, so you need to find other ways to move them.

Normally the walls are friendly: they just stop the particles, but you can draw bonds over them without limitations. Dark walls, however, will destroy particles that hit them, which isn't a good thing, because to complete a level you must destroy the particles only through collisions. Additionally, bonds cannot pass through dark matter, so e.g. in the level below you can't bond the two red particles.

There are many other elements introduced later, like "uncertain" particles, energy fields, unstable particles. This helps keep the game varied through its 60 levels.

The game plays in real time, however it doesn't feel like an action game, because the speed is quite slow. The levels feel more like proper puzzles, because figuring out what to do is harder than timing your actions correctly. Many of the levels have an easy, obvious solution which unfortunately isn't enough to collect the neutrinos. To get those, you often have to go significantly out of your way.

The user interface is improvable. I found it annoying that there isn't a button to immediately restart a level: you need to go through an intermediate menu. I was also put off by the very long fades and unskippable splash screen that happen when you launch the game. It all gives a feeling of a "console" game, instead of a mobile game that one wants to load as quickly as possible.

The game doesn't work well on phones, because everything is very small and difficult to interact with. Additionally, on my 4th gen iPod Touch it ran at a rather low frame rate, making it sluggish and difficult to control. On iPad Mini it works fine.

Curious about what the ?????? button I mentioned at the beginning does? I'm not going to spoil the surprise: you'll need to collect three neutrinos in all levels to see for yourself. However, I think that to make the effort really worthwhile there should be Game Center integration, which sadly is missing.

All in all, this is a nice relaxing game which is worth a try.
