Upgraded to Xperia 10 III, any chance for an aarch64 build...?

Hey, I haven't worked on this for a decade and I have no idea how well the code would compile on a current Qt toolchain. I don't currently have extra time to put into this in the foreseeable future due to family, but if someone wants to try the code is here: https://github.com/bzar/ultimate-tic-tac-toe

IMHO "Intermediate" is the most advanced AI. All others make ridiculous mistakes...

Now that I've mastered it... We need an online multiplayer mode!

I don't really understand what rules are used when a sub-grid is automatically selected. Is it just random? Also some effect would be nice when the game is over.

Never mind, I figured it out - genius! Better highlighting still applies. - Interesting would also be a undo-last-move option to refine strategics...

i486 would be nice....

A bug: When the opponent sents you to a full grid that has not been won, there is no possible turns and the game is stuck. Easy to test in two player mode.

Fixed! I also tuned the AI a bit.

there is a bug: if you are X and you tap on O, the O becomes X... (and viceversa)
