The goal is to eliminate all the balls on the board. The game ends if there are no more balls (you Win), or if there is no more possibility to eliminate them (you lose). Balls will be eliminated if balls are touching, horizontally or vertically. Non-ball objects are movable, but will not be eliminated.

Use the arrow keys to move the balls. Clicking X will reset the board.

For every level, there is a maximum number of steps. The game will end (and you will lose) after this number of steps.
