I remember having this exact idea multiple years ago and playing that with people, now someone made a game based on that idea, cool!

Except we would compete for a single square and then move on to the next, not all at the same time, because it becomes luck-based that way.


Haha, cool!

Not sure I understand the end, there is no luck at all in this game : The big case in which you can play is determined by the small case the other player chose.

oh my god how did I miss that? That is genius, sorry for that, that is more interesting than the game I thought of when I was little

i love this

Great job! Would you like to make an android version on mobile phone?

I'd love to! But I rely on TIC-80 software and that should not be possible before maybe a year, maybe more.

However, if you ever want to play it offline with a better interface on android you can do the following:
1. Download and install TIC-80 from https://tic80.com/create
2. Download Ultimate tic-tac-toe on your phone by doing the following:
 - Open TIC-80 and type `surf`
 - Find Ultimate tic-tac-toe in folder tic80.com -> Play -> Games
 - Once you are on the game press back on you phone to access the menu and click "Close game"
 - Go back to root folder selecting [..] -> [..] -> [..]
 - Press back on your phone again
 - Type "save /tic-tac-toe.tic"
3. Play Ultimate tic-tac-toe by doing
 - Open TIC-80 and type "surf"
 - Choose "tic-tac-toe"

thx a lot.

Great ! so simpl yet so intersting to play !

I hope you get more players



I introduced the game, I hope you like it.

Great, thanks!

LOL i had the same idea xd




How about treating developers properly?


How about taking a harmless joke?

i finally beat very hard :D very fun to figure out


This has existed before, so it's not that original :P

Yes, totally. That's a game I love and I wanted to advertise, but I did not create it. It even has a wikipedia page. However, the AI (with TIC-80 limitations) is my creation.


This is a really creative take on the classic game. I love it.

I love it!!

I really miss playing this tic-tac-toe style with my bestie and now I can play it like this :DD


No, TIC-80 which is an excellent free and open source alternative ;)

This is a very nice and very funny game. I played a few rounds at it was very challanging sometimes! I very like the game idea!


Nice concept and constantly improving

What a clever design! And it's got 2 player 😊 Glad it works pretty well on my phone browser too. (There's some slight glitchiness with the end of game "Hide" button but that's about it)

Great game!

Thank you very much!

On which platform do you have glitchiness? I'll try to fix it

Very clever, nicely done
