There are lots of Tic-Tac-Toe (Noughts and Crosses, whatever) games and strategies out there, but not many truly 3-dimensional games. There are variations which require players to stack a piece on top of a previously played piece, which changes the game. There are games made with a 4-by-4-by-4 array, which eliminates the problem of the first player always winning on the third move, as happens with a 3 by 3 by 3 array. And there are virtual games and formats to play on a single sheet of paper. But there aren’t many ways to play Tic-Tac-Toe in three dimensions the same way it’s played in two.
Here’s a solution. This is a 3 by 3 by 3 array that allows players to play in any space in any order. The one rule change is that the center space is not allowed on the very first move.
