Sure! Here's a complete implementation of a tic-tac-toe game in a single HTML file. The game is playable on smartphones and uses pictograms for X and O symbols. The implementation is enclosed within the script tags and written in JavaScript.
To play the game, simply copy and paste the above code into a new HTML file (e.g., `tic-tac-toe.html`), and open the file in a web browser on your smartphone. You'll see a tic-tac-toe board displayed, and you can tap on the cells to make your moves. The game will notify you if a player wins or if it's a draw. Have fun playing!
