As a traditional board game played with go pieces (black and white stones) originated in China. The black one should go first. Every chessman must put at the cross. The man who first makes 5 chessman in a row win the game.
Place your tiles on the board so that you can get 5 in a row diagonally, vertically or horizontally. Don't let your opponent get 5 though!
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
