great work harray vaia

Run code

you did great harry vai love from NEPAL

Please code the same game but the opponent should be a computer. So, human vs computer.

Thank you harry bhai :)

Hi harry, can you play tic-tac-toe with AI ?
Please code the same game but the opponent should be a computer. So, human vs computer.

Major Update

I modified your code and included some major updates like save/load feature, AI opponent, etc. This is currently under development but soon this update will be available from my forked repo of this repo.
