A devilish twist on noughts and crosses: both players mark X, and completing a line loses you the game.

How to play
Take turns placing an X on any open cell. Unlike normal tic-tac-toe, there are no Os and no winner by line. Whoever is forced to complete a three-in-a-row loses that board, and on a single board that means the game.
Every mark is an X, shared by both players
Completing three in a row kills that board
On multi-board games, play continues on the surviving boards
Avoid being the one who fills the final line
