The game starts with two black and two white discs in the center of a eight by eight (64) squares game board. The player moves the white discs, the computer plays with black discs.

At each turn the player moves by placing a disc in an empty square so that he can flip the enclosed opponent disc or discs to his own color. The enclosed opposite colour discs should be in vertical, horizontal or diagonal line.

The game is over when all the game board squres are filled with discs.
The winner is the one with more discs of the same colour.
