Antimatter is the latest game from Pangea Software, the creators of Enigmo. It is extremely simple to get started with this game but it is (thus far) difficult to master, which keeps the game play fairly addictive.

The game's premise is that "you control a stream of antimatter particles and use it to affect the Cosmic Strings while collecting powerups and bonus points." How this works is that you control direction of the antimatter particle with your finger and you have to bounce the particle into each of the blue Cosmic Strings, which then turns the Strings red. Once all the Strings are turned red, you clear the level. Antimatter's graphics are stunning.

The game has a number of challenging aspects. The first is that you have a limited amount of energy and you have to clear each level before your energy runs out. You can collect more energy by hitting the Strings or "power-ups" that appear on the screen. As time progresses, the Strings break into smaller pieces (which makes then infinitely harder to hit) and you can accidently turn a String back to blue by hitting it a second time. The first few levels are fairly simple to clear but it gets complex quickly as more strings are added at each level.

Antimatter is only $1.99 from the iTunes App Store.
