Something is broken
Tell us which game, what you did, and which browser and device you were on. A screenshot helps more than anything. Bugs get fixed faster than anything else in the inbox.
A game we should add
There are dozens of tic tac toe variants and we have twelve. If you play one we are missing and can point us at the rules, we will look at it seriously.
Classroom and teaching use
Teachers use these boards for lessons on strategy, logic and game theory. You do not need permission, but if you want a specific variant or a printable board, ask.
Advertising and business
Questions about the ads on this site, or about working together, go to the same address. Please put the reason in the subject line.
Before you write about a lost game
If the computer beat you and you think it cheated, it almost certainly did not. On the 3x3 boards the Master setting searches every remaining move to the end of the game, so it plays perfectly. Try the same position again on Casual and you will see the difference. If you think you have found a genuinely illegal move, that is a bug and we want to hear about it.
