TIX.TAX is an advanced version of Tic Tac Toe, the exception is that there are nine games.
When you win three games in a row, you win the entire game.
But that is a lot more difficult than it seems, because the move you make controls which game becomes clickable for the opponent.
Because of this, TIX.TAX is a lot more challenging than Tic Tac Toe.
You have to think a lot further ahead if you want to win.
