Move 2 balls to the same color cell. Blue ball to blue cell, yellow ball to yellow cell.
Use cursor keys to move 2 balls.
Balls move to selected direction until wall at same time.
If your cursor key do not response, click on the screen once.
I have replaced "BallBoard2.class". If you play locally, download this class file please.
If you use oldclass, start position of ball is different.
