Sure, here's an example of a simple game implemented as a single HTML file using JavaScript and enclosed in script tags:
Pictogram Game
🤜
🤚
✌
In this game, you can choose between rock, paper, and scissors by tapping or clicking on the corresponding pictogram. The computer will make its choice randomly, and the game will display the result (whether you win, lose, or it's a tie) based on the traditional rock-paper-scissors rules. The results will be shown below the pictograms.
