Multiplayer TicTacToe

This version of TicTacToe has been boiled down to its rawest form. You choose a nickname, select a room to join or create your own and then it's just you and your opponent.
Sweat, blood and tears are a common sight amongst players of this vicious game. Will you beat your foe into submission by a combination of clever and quick strikes? Or is it you who will eat dirt and dust whilst you are crawling beneath the feet of your enemy, begging for a chance to live and play on?
It is your time to choose.
