This is billed as "the ultimate tic-tac-toe" and has some resemblance to nine men's morris. The array is 4x4, and players alternate placing one of their 6 pieces on, placing one of the two wild pieces on, or moving/jumping with one of their pieces or the wild pieces. The goal is to get 4 in a row, make a square (2x2), or occupy all 4 corners. There are a number of anti-stalling rules and stakes raising, as in backgammon to round out the game. 1993 Mensa Select
