Some checkers are lined up, with blue on one side, red on the other, and with one empty space between them. A move in this checker game pushes any checker forward 1 space, or jumps over any 1 checker of the other color. Jumping the same color is not allowed, moving backwards is not allowed, and 2 checkers cannot occupy the same space. You complete the puzzle by switching the colors completely: ending up with blue on the right, red on the left, and with 1 empty space between them. Drag the checkers to move them.

(There are 6 checkers and 7 spaces, one empty space being in the middle)
