Well, of course it is mobile friendly, I just put that to make it sound better. How To Play- The game will start off with Player 1. You can place down X/Os by clicking a part of the grid. Player 1 controls X, and Player 2 controls O. The game ends when someone gets 3 in a row, either vertically, horizontally, or diagonally, or when the board is filled up and no one has won.
Almost all code by me and @akumar2-tcssm. You should check out her version, too!
