The basic concept of Polyhedra is incredibly simple: Hold a finger to the screen to create a shape. The longer you hold it, the larger the shape will grow. Fill at least 66% of the screen with shapes, and you complete the stage. The wrinkle, and it’s only a slight one, is that your shape can be popped if an enemy encounters it while it grows.
The key here is to watch out for the enemies that bounce around the level as you grow your shape, and to let go when they are about to hit it. If the shape is completed, the enemies will just bounce off them harmlessly like they do the walls. You are only given so many shapes, and if you run out, you lose.
Trap the mini-bubbles before you’re popped.
There are a few different shapes to contend with, from circles and squares to hexagons. Each shape gets its own level, each consisting of limitless stages. Stage one will have one enemy, and stage two will have two and so on. It’s not terribly difficult through the first ten stages, and you only need to get to stage nine to unlock a new shape and level.
When you get into the later stages, increased enemy numbers make things more difficult. There’s one more tool you can use to your advantage however, and that’s gravity. As you tilt the screen, the shapes will fall to the bottom and rearrange themselves. Not only does this allow you to make room to create more shapes, but you can maneuver them to trap the enemies against the wall or between shapes, giving you breathing room to create new ones.
At a certain point, the game will make things more challenging by disabling your ability to tilt the screen, making it much more difficult to trap enemies. This forces you to make smaller and smaller shapes, and fitting them together without wasting too much space between them can be difficult with the more complex ones.
The building blocks of success… are octagons.
Once you complete all the levels, there is a medley level that will force you to use all the shapes at once. There’s really not much to do here once you unlock all the levels, except try to improve your score. Luckily there are online leaderboards, although they’re pretty sparsely populated at the moment.
Although the game concept itself is pretty basic, the presentation here is very slick. The backgrounds all smoothly shift color, from blues and pinks to greens and yellows. The music blends appropriately, but you can also play your own if you’d like or turn it off altogether.
Polyhedra doesn’t do a lot, but it wrings the most out of its basic concept. The serene ambiance and slick tunes contribute to a game that adds up to more than the sum of it’s parts. If you’re looking for a different sort of puzzler, we suggest you give it a try.
