A simple strategy game wherein 2 players (you vs. the computer) take turns placing one of two coloured tokens on the board. A player is free to place whichever colour token he chooses on the board provided that (1) the square is empty, and (2) a token of the same colour is not located directly next to it (on either side nor directly above or below it). The last player to successfully place a token on the board wins. Though the rules are simple, winning can prove challenging!
