Notakto
The Board
Notakto is played on an arbitrary number of tic-tac-toe (three-row, three-column) grids. The grids are empty at the start of the game.
Rules
Players take turns placing an X on an empty space on one of the tic-tac-toe grids. If a horizontal, vertical, or diagonal line of Xs is created on one tic-tac-toe grid, that grid is dead and neither player can place an X there anymore. If a player forms a horizontal, vertical, or diagonal line of Xs on one board and all other boards are dead, then that player loses.
