3DTicTacToe app for iPhone and iPad

Tic-Tac-Toe 3D is a 3-Dimensional Tic-Tac-Toe game.
Players place O and X marks on the 3X3X3 cubic playing field, just like a regular Tic-Tac-Toe game.
The only difference from the original Tic-Tac-Toe is that players can form consecutive marks within the 3-dimensional grid.

The game has three playing modes.
- watching computers battle.
- single-player mode (play against computer)
- two-players mode

For single-player mode there are three levels of difficulty: Easy, Medium and Hard.

--------Rule--------
The first player to create three lines formed by three consecutive marks in
the horizontal, vertical or diagonal rows using the 3-dimensional playing
field, wins the game.
