In the game, blocky pieces of non-uniform shapes and sizes fall on the touch screen. When a falling piece hits something and stops, players can tap the blocks within the piece and place them in a block register, then transfer them into different spots on the screen. Blocks can be cleared when a falling piece hits something in such a way that it creates a rectangle. When blocks of each color are cleared, they travel to the top screen and are assembled into a shape, always of a sprite from an NES game; when the sprite is fully assembled, the player has beaten the level. If the player fails to clear enough blocks in time, and blocks accumulate at the top of the screen, preventing new blocks from falling, the game is lost. In order to prevent this, players can use a [[POW Block]] button, which causes all the blocks to fall to the bottom of the screen, but forfeits one of the spots in the block register.

Whenever players clear blocks, they get [[coin]]s, which appear using their sprite from ''[[Super Mario Bros.]]'' These coins can be used to purchase dark levels, which contain other sprites from the game in their corresponding light level. Beating a stage with a score above the stage's target will put a [[Super Star]] icon next to the score display.
