Ok this is cool.First issue tho i saw skimming is your set %chan: set %chan = $input(Enter a channel for tic tac toe,eod, PaPaYa\'s Tic Tac Toe Script) .You have a \'=\' there.Also this msg $chan Cats Game! Gameover! | gameover: returns Cats Game! Gameover!
Cats No such nick/channel.Change the $chan to %chan.Also maybe $strip so people can play with colors on.Speakin of colors i was asked to ask to add colors like green for O and red for X.I can add it my self but they thought it was a good idea to ask.Other then that is ace.`-.-
