One player is Mix, the other Match. Both may move either of the two types of pieces. However, Mix can only jump and capture pieces if they are different from each other (i.e. an Apple with an Orange) and Match can only jump and capture pieces if they are the same as each other (i.e. an Apple with an Apple).
 
Pieces can jump in any direction. If the capturing piece can make another capture, it may do so or it may pass. Pieces can only move by capturing. The first player unable to make a move on his turn, loses.
