The game is similar to the traditional game of tic-tac-toe, but is played on four 4×4 grids stacked vertically; it is basically a computerized version of the board game Qubic using traditional tic-tac-toe notation and layout. To win, a player must place four of their symbols on four squares that line up vertically, horizontally, or diagonally, on a single grid, or spaced evenly over all four grids. This creates a total of 76 possible ways to win, in comparison to eight possible ways to win on a standard 3×3 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 settings. The game uses the standard joystick controller.
