Tictactoe

During my process of learning Lua I figured I needed something as a goal. After a bit of tinkering with some different programs, I came up with this. It does exactly what the title says it does.

It has to run on an advanced computer as it uses the colour API. If anyone wants to critique the code, please do. I would like to know of better ways to accomplish most of what I have done.

nice code there seems efficient enough to me has run without a flaw so far, keep it up :)/>

Really nice! I like how it is not complicated and easy to understand!
