This game entails erasing all the blocks to clear the surface within a set limit of time. If you fail to complete this task, the game ends.
Move the blocks to the right and left with Button A and Joystick. If you combine the same patterns they are cleared.

Blocks which get in the way can be destroyed with bombs that move up, down, left and right. The number of bombs is limited.
If you make a bad move, you can return to the original starting point by pressing Button B. The number of time is limited.
