One of the most popular segments of my in-person professional development was the chance for teachers to try **Ultimate Tic Tac Toe** — an advanced version of Tic Tac Toe. I used it to illustrate how adding complexity increases interest. **Adults who would be bored to tears by Tic Tac Toe are sucked into Ultimate Tic Tac Toe**. I’d have to *beg* them to stop playing so the session could continue!

I have a Byrdseed.TV video demonstrating Ultimate Tic Tac Toe or you can also just read more about the rules at Wikipedia.

Now Ultimate Tic Tac Toe is *quite* complex. **Perhaps, too complex for some folks!** And it certainly takes a long time. Maybe you just can’t fit it into your day.

### Playing Tic-Tac-Toe in Some New Ways

Fear not! For there are **dozens of tic-tac-toe variants** out there. Some are more advanced and some simpler. I’ve built out videos for a bunch of them (see the current list here), but I’ll also sum them up here:

- Misère Tic Tac Toe: Exactly the same as regular tic-tac-toe, but you win by forcing
*your opponent*into getting three-in-a-row. Yes, you win by losing! - Gomoku: The board is 15×15 and you must get exactly five-in-a-row to win. Six-in-a-row doesn’t count!
- Wild Tic Tac Toe: Uses a standard board, but both players can play as X
*and*O. First to make a three-in-a-row using either shape wins. - Order and Chaos: The board is a 6×6 grid. Both players can play as X
*and*O. One person (Order) wants to get five-in-a-row of either shape. The other player (Chaos) tries to prevent any five-in-a-rows (so, Chaos wants a cat’s game). - Notakto: Played on three standard boards at once. Both players play as X. You can play on any of the boards on your turn. The first person to complete a three-in-a-row
*loses*.

And, of course, Wikipedia has a huge list of Tic Tac Toe variants.
