3-D Tic-Tac-Toe

The game is similar to the traditional tic-tac-toe game, but played on four vertically stacked 4×4 grids; it is basically a computerized version of the board game Qubic with the traditional tic-tac-toe notation and arrangement. To win, a player must place four of their symbols on four squares that are vertical, horizontal, or diagonal on a single grid, or evenly distributed across all four grids. This gives a total of 76 winning opportunities, compared to eight winning opportunities on a normal 3×3 game board. The game has nine variations: It can be played by two players against each other, or one player can play against a built-in AI on one of eight different difficulty levels. The game uses the standard joystick controller.
