The developer of Trism, Steve Demeter let the news out on his income at a conference. The app did receive some press coverage prior to its release at the launch of the App Store, however, this is still evidence of just how popular a platform the iPhone can be for games.

Since it’s release on July 11, Trism has sold over 71,000 copies. That clocks in at an average of 1,200 copies a day! You can currently purchase Trism from the App Store for $4.99.

Trism requires that you slide the trisms so that they create a combo of three of the same color. Once you do this, they are eliminated from the board and new ones slide down into their place. Here’s where the neat part comes in. You can tilt the iPhone in any direction to change the gravity so the trisms fall and fill in spaces. Open spaces in the board make it more difficult to make matches, says the tutorial, so turning the iPhone on its head can actually help you score big points!

This game only costs $4.99 and it seems to offer hours of gameplay and really, it’s like three games in one. First, there is “Infinism,” a game that allows you to take your time and really plan out your matches. The second version is called “Terminism” which is timed and if you can’t make a match by the time the counter counts down, you lose the game. Lastly, there’s “Syllogism” which is my personal favorite. It really makes use of the accelerometer. To play this game, you must hold the iPhone flat and tilt it so that the trisms fall and match up with each other. It starts out easy, as you can see from the photo below, but then it picks up and can get quite complicated.

To spice it up, there’s also bombs, locks and obstacles that can get in your way and require strategic matching to eliminate. And when you make a match of five trism or more, a rainbow trism will appear and, you guessed it, this allows you to match two trisms of any color with it.

All in all, I enjoyed this game. It’s a fun way to pass the time and with clear graphics, fun sound effects and challenging gameplay, you’re sure to get caught up in all the matching fun.
