Computer Intelligently playing 3D XO Game
The game is basically the same as regular tic-tac-toe: you try to win by getting three X’s or O’s in a row. The trick is, instead of one grid of nine squares, you have three grids of nine squares, all stacked on top of each other. A diagonal, horizontal, or vertical set of three lets you win, but since the game is 3-D, there are many more winning possibilities. After completing cube of 333, four new surfaces are formed from which winner of each face can be decided. Player winning maximum faces out of 7 wins the game.
