Sure! Here's an example of a simple game implemented as a single HTML file, containing JavaScript code enclosed in script tags. The game is designed for smartphone operation and uses pictograms.
Score: 0
In this game, the user can choose between three options: a rock, a paper, or scissors, represented by pictograms. The user's choice triggers the `playGame()` function, which randomly selects the computer's choice and compares it with the user's choice to determine the outcome. The score is updated accordingly, and the updated score is displayed on the screen.
Hope you find this example helpful in creating your own game! Feel free to modify and enhance it as per your requirements.
