Sure! Here is a simple implementation of Tic Tac Toe as a single HTML file using JavaScript. The game will be playable on a smartphone, and I will use pictograms to represent X and O.
Tic Tac Toe
To play the game, simply open the HTML file in a web browser on your smartphone. You can tap on the cells to make your moves, and pictograms representing X and O will be displayed in the respective cells. The game will detect the winner or a tie and alert you accordingly. To start a new game, simply refresh the page.
Please note that this is a very basic implementation of Tic Tac Toe, and there is no AI opponent. It allows for two human players to take turns.
