XO: Tic Tac Toe 3D is the ultimate casual game for iPhone!

Based on the familiar game of Tic Tac Toe (noughts and crosses) the rule is simple: place your pawns in a horizontal, vertical or diagonal row within a three dimensional grid to win.

But the challenge doesn’t stop there! Work your way through the 3x3x3, 4x4x4 and 5x5x5 grids with a few twists along the way!
