[1] Notakto is played on a finite number of empty three-by-three boards.

[2][9] The optimal strategy for a single-board game of Notakto allows the first player to force a win.

[9] This strategy works because it makes a boot-like structure, which is called the boot trap.

From the boot trap position the first player will be able to force a win.

Then, the second player sacrifices one of the boards (by making a three-in-a-row) if it is possible.
