The three sport balls are depicted
on the surface of six square tiles as shown in the Start
position; two balls are complete, and the third one
consists of two halves. Each tile can slide to an
adjacent free space. To move a tile simply click it.
The goal is to rearrange the tiles so that the third
ball becomes complete. Of course, one of the two balls
being on the Start complete will split into two halves;
you can even choose which one it will be. Two Goal
positions to choose from are shown at right.
