Tic-tac-toe is a paper-and-pencil game for two players, “X” and “O”, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game.
This demo is a simple and dumb two-player version where the intention is to demonstrate a simple form-based project.
