The aim of this game is to remove all the balls, but one, from the game board.
A ball is removed when another ball jumps over it.
A ball may jump over another ball if it is in an adjacent place to it (up, or down, left, right), and if the destination slot on the other side is empty.
To move a ball, first touch it: its color will change to blue; then touch the destination place.The ball will move to destination, and the ball in the middle will disappear.
A successful game ends with the last ball in the upper left corner of the board.
If you are not satisfied of our last move(s), you can undo one or more of them, using the Undo Move button.
If you cant guess a valid sequence of moves, you can get a hint touching the Auto Move button: this will reset the board to the initial state, and will activate a sample automatic sequence of 35 successful moves. Just hit Stop if you want to interrupt the sequence, and return to normal play.
