This is Tic-tac-toe I think everyone knows how to play it but I've a few quick things to say anyhow. O goes first, space bar to restart, when you win a screen comes up that says who won and last but most importantly this is not a server you still need two people to play this. (If you know how to make this a server please comment eventually I would like to make it so you can play online, Thanks!)
Credits to @twonerds for the intro. All other coding I did myself @OllieDog9 and don't think it was easy it took me 2 weeks to complete. Still might be some unknown glitches. If you find any and it is related to one of the "win" screens not coming up then be sure to list what number the squares of the win were. (listed from left to right and top to bottom).
