To play the game, simply copy the code above and save it as an HTML file (e.g., "pictoguess.html"). Open the file in your web browser, and the game interface will be displayed.

If the guess is correct, a congratulatory message will be displayed, otherwise, an alert with a hint will appear. The game then moves to the next word represented by a new pictogram.
