Six! is another breakout hit from the minds that brought you 1010! and Merged!
The aim of the game is to move your hexagonal block down the screen, as doing so earns you points. In order to do this you'll have to tap different blocks, causing them to disappear. The hexagon will then fall into the empty space left behind.
It sounds simple enough, and the mechanics won't take you long to master, but as time goes on you'll find yourself at the mercy of the game's devious mechanics. If the blocks are destroyed, the hexagon will start to wobble and roll, and the tower will begin to tilt. It is your job to keep the tower balanced. If the hexagon tips into the abyss, it's game over.
