Use your head and choose the appropriate tactics to give the opponent a hard lesson. Who will win this time? You or your friend? Try your hand in the fight for victory. First, who work out the line: horizontally, vertically or diagonally with specified number of discs will win! This is a job for real Cerebrates. Is this time you'll take the victory and not share the maximum number of points? Perhaps it was your pal will be a world champion in the game of logic for two. There is no room for co-operation - only rivalry one on one.
