About 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 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.

On Atari 50: The Anniversary Celebration since Nov 11, 2022 — the cartridge is now a collectibleLow counterfeit risk

Atari 2600 prices, all games & how to spot a fake

Carol Shaw's four-layer tic-tac-toe, a thinking game more than a showpiece, and on Atari 50.

3-D Tic-Tac-Toe is Atari's 1980 cartridge of the board game played on a 4×4×4 cube, where you need four in a row, horizontally, vertically or diagonally through the layers. Carol Shaw programmed it, and Atari released it in July 1980, with Sears also selling it.

It is a slow, cerebral game rather than an action cartridge. It is on Atari 50: The Anniversary Celebration if you only want to play it.

How it was made

Programmed by Carol Shaw and released by Atari in July 1980. Sears also sold it.

Cartridge & preservation record

Program size 2 KB, measured from the preserved dump.

Catalogue number as recorded for the physical release.

Worth knowing

Discontinued by 1983. Atari Age's Solution Section called it "an old, discontinued Atari cartridge".
1981 dealer price. Atari's confidential retailer price list for January 1 to June 1, 1981 lists 3-D Tic-Tac-Toe (CX2618) in its basic tier: dealers paid $14.00 against a suggested retail price of $22.95. The same list groups it among the "cartridge titles introduced in 1980".

Before you buy

Low risk. Two listings are priced: the standard cart and one listed as 3D Tic Tac Toe [Text Label]. Loose, both are cheap. Sealed standard copies are priced far above the loose and boxed ones, so if you are paying a sealed premium, inspect the wrap and box closely.
