xBarrier Description:

This game is played on an empty NxN square board
Build fences and stalemate your opponent in this simple and addictive game. At each turn, each player must move his stone. The stone moves similar to a chess Knight, but in two steps rather than one. All positions moved to or jumped over turn into an impenetrable barrier for both players. The stalemated player loses.
