The objective is to be the first to move all of your pieces to the opponent's starting positions on the board. If you can't make a move, you lose. Pieces move as far as they can in the direction of one of their arrows. Summer can move South and East. Winter can move North and West.
 
Often, the best strategy is to block your opponent from moving. It is very easy to place your pieces in such a way that they can't be arranged on the opponent's starting squares, especially on the bigger boards. Be careful.
 
Click on pieces to move. There are nine variants total. The first lets you get used to play. The second variant plays the same as the front-cover game "Change!" on the March 2002 GAMES magazine. The very last is a 10-piece swap that is very difficult. The play is similar to Dodge 'Em, Breakthrough, Ugly Duck, and Sidewinder, but there is no capturing.
