is a puzzle game. The aim of the game is to fit together rotating gears of different sizes. At the start there are blue and yellow gears on the screen. The yellow gears move while the blue do not. To complete a level the player has to make all blue gears move by using grey gears that connect them to the yellow gears. There are gears in five different sizes and for every level only a limited quantity of gears is available. With the use of touch controls the player simply drags the gear around the screen. The placement of the gears is affected by gravity and they will fall to the bottom if not connected to another gear. Some levels have red striped areas where gears cannot be placed. The player then has to build around these.
