Sure! Here's an example of a Rock, Paper, Scissors game implemented as a single HTML file using JavaScript. It utilizes pictograms for easier smartphone operation.
Rock, Paper, Scissors
Score: 0
The game starts by displaying three choices: "rock", "paper", and "scissors" as pictograms. When the player taps on one of the choices, the `playGame()` function is called with the selected choice as an argument. The game then randomly selects a choice for the computer and determines the winner using the `determineWinner()` function. The result is displayed on the screen, along with an updated score. The player can play again by tapping the "Play Again" button, which calls the `resetGame()` function.
