TicTacToe

This is yet another tic-tac-toe game.

To win, you must align a row(Of the diagonal or vertical or horizontal)
But,,,
- the stone has three levels.
- you have two stones in each level ( so, totally, you have six stones)
- you can put free space
- if your stone level is higher, you can put on the enemy stones
- you can move putted stone

To prevent the enemy from the aligned
Not only put a stone in the free space,
It's okay to put the stones of his opponent's stone.
That's become the attack of their own as it is.
Attack while defense.
