The goal is to eliminate all balls in the board. The game will end if there is no more balls (You Win), or if there is no more possibility to eliminate them (You lose). Balls will be eliminated if there are more than one ball in the horizontal or vertical direction. The non-ball objects are movable, but you cannot eliminate them (and it is not the goal).

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