3-D - Tic-Tac-Toe

The game is similar to the traditional game of tic-tac-toe, but is played on four 4×4 grids arranged vertically. To win, a player must place four of his symbols on four fields in a vertical, horizontal or diagonal pattern, either on a single grid or evenly distributed across all four grids. This gives a total of 76 possible ways to win.
