From Publisher: "The goal is simple: control every stack on the board. The higher your stacks, the greater your reach. But to use that reach, you must unstack your pieces, and unstacking may release an opponent's piece that will be used against you. Pieces can move across the entire board in one turn, so you must think globally as well as locally. Tessaron is a different game every time you play. The tide can turn at any moment, so you will have to stay on your toes. The rules are easy to learn, but it could take a lifetime to develop a winning strategy!"
