One begins in the center square (highlighted). The number in that square indicates the number of spaces you may jump either to the left, right, up, or down. You may only jump to another numbered space. Once you leave a space, it disappears to reveal part of the image below. You win if you are able to remove all but one square (which will be removed automatically for you). As the number values are generated randomly, there is no guarantee that the game is winnable... sorry.
