You spawn within a circular arena, which acts as the out of bounds limit. You tap on the left hand side to jump left, and tap right to jump right. Various different objects moving around. The blocks to avoid move either horizontally or veritcally, are either a large or small square, and can either move fast or slow. The other objects (acting as a comet with a white tail on their end) are collectable, yielding one coin. These can be used in the shop to buy different skins.
