Try to beat your iPhone or your Apple Watch in this classical Tic Tac Toe in 3 dimensions.
The game is similar to the traditional game of Tic Tac Toe, but is played on three 3×3 grids stacked vertically. To score a point, a player must place three of their symbols on 3 squares that line up vertically, horizontally, or diagonally, on a single grid, or spaced evenly over all three grids. The winner is the one who scored the more points when all symbols have been placed.
World rankings are available for both Apple Watch and iPhone.
