Tic Tac Pow

It's played like a Tic Tac Toe but with larger grid and special cell.

There are 6 special cells :
- Extra move : to place two mark in one turn (the second mark cannot activate another special cell)
- Erase : to erase any player mark on the grid
- Stamp : to replace a player mark by your mark
- Ping : to place randomly another mark on the grid (can activate another special cell)
- Permanent : to make the mark impossible to be erase by stamp or erase
- Random : to play randomly one of all the other special or may be nothing
