The basic idea of the game is to rearrange the balls within the labyrinth rather than finding your way out. The balls will roll until collision in the direction of the arrow to be selected for each step. For example, while you are trying to send the red ball to the desired place the other ball will roll to and fro as well.
 
At the start of the game, for example, you may need only 12 steps to solve the basic problem and change the place of the two balls in the middle of the field.
 
In the variants there are additional neutral balls to get in your way.
The third variant presents a difficult challenge where all balls need to line up to win.
 
You can redesign the labyrinth and propose your own problem (use the right mouse button to build or pull down walls).
