3-D Tic-Tac-Toe

3-D Tic-Tac-Toe, also known by the trade name Qubic, is a board game. It is similar in concept to traditional Tic-Tac-Toe but is played in a cubical array of cells, usually 4x4x4. Players take turns placing their markers in blank cells in the array. The first player to achieve four of their own markers in a row wins. The winning row can be horizontal, vertical, or diagonal on a single board as in regular Tic-Tac-Toe, or vertically in a column, or a diagonal line through four boards.

Pencil and paper

Like traditional 3x3 Tic-Tac-Toe, the game may be played with pencil and paper. A game board can easily be drawn by hand, with players using the usual "naughts and crosses" to mark their moves.

In the 1970s 3M Games (a division of 3M Corporation) sold a series of "Paper Games", including "3 Dimensional Tic Tac Toe". Buyers received a pad of 50 sheets with preprinted game boards.

"Qubic"

"Qubic" is the brand name of a version of the game manufactured and marketed by Parker Brothers, starting in 1964. It was reissued in 1972 with a more streamlined design. Both versions described the game as "Parker Brothers 3D Tic Tac Toe Game".
