Score 4 is a common TicTacToe variant, manufactured by many different companies and strange names like Ballchess (?). It's actually just Connect4 in 3 dimensions.
 
Object: Get four of your marks in a row horizontally, vertically, or diagonally. One side takes Blue and the other side takes Red. Players alternate placing Balls on open bottom intersections. The Four-in-a-row can be formed along any line.
