Sure, here's an example of a tic-tac-toe game implemented as a single HTML file using JavaScript:
Tic-Tac-Toe
This HTML file creates a tic-tac-toe game with a 3x3 grid represented by a table, where each cell can be clicked to make a move. The game checks for wins and draws, and allows players to restart the game. The symbols "X" and "O" are used as the pictograms for the players.
