Trism is a puzzle game for the Apple iPhone developed Demiforce Llc. It makes use of the iPhone's built in accelerometer. It involves the sliding of colored triangular tiles called trisms on the screen in order to make matches of 3 or more. As soon as a match is made the tiles disappear and depending on the direction in which the iPhone is tilted the gaps left behind will be filled.

Gameplay

edit

Trism has three built in gameplay modes:

Infinism

edit

This is the main gameplay mode in which the user slides the trisms on the screen diagonally or horizontally in order to create matches of three or more trisms, the remaining gaps left behind are then filled by the surrounding trisms depending upon the direction in which the iPhone is tilted. This is shown by the compass in the lower right hand corner. The more trisms matched together the greater the amount of points generated. Once a certain amount of points is generated, the player then advances a level. During gameplay the player can encounter certain special trisms, such as the locked trism, which prevents trisms that are on the same axis from being moved until it is removed by matching it. There is also the bomb trism that has a countdown which decreases with every successful movement made, this trism can be moved but must be removed by matching before the countdown finishes or the game will finish.

Terminism

edit

Terminism has the same basic gameplay as Infinism mode but with the addition of a timer. When the timer goes from green to red, called a timeout, a bomb or lock trism will spawn. In order to keep the timer green, matches must be made constantly.

Syllogism

edit

This is a puzzle mode whereby the player must eliminate all of the trisms in the least amount of moves possible. This is done by tilting the iPhone in order to make them slide. There are 30 levels each increasing in difficulty. Some of them are solvable under par.

Achievements

edit

The game has achievements for completing certain tasks, such as earning over 500,000 points in terminism mode before getting a timeout. There are 22 achievements in all. They are posted on the users profile on the online community.
