Hi Everyone!
In this post, I will show you how to make an unbeatable emoji tic-tac-toe that makes fun of you if you make a move or lose. It is made with HTML, CSS, and Javascript. You cannot win this game. The most you can get is a draw. Follow me if you want more projects.
Let's start with the HTML Design:
