Solitario Palm OS 1.0

To win the game, you must eliminate all the balls on the board and leave only one.
To obtain your objective, select the ball you wish and makes it move in the direction you want.
First select a ball. This one can jump over of a position that is occupied and it will fall in the contiguous cell to the selected one, that will have to be empty.
When you perform this action, the ball over which it has gone disappears and the cell is empty. Movement on diagonals is not allowed.
It is not as easy as it seems.
