Sure, here's a simple game implemented as a single HTML file using JavaScript. The game is a guessing game where the user needs to correctly identify the pictogram displayed on the screen. It can be played on a smartphone.
In this game, a random pictogram is selected from the array, and the player needs to enter their guess in the input field provided. After clicking the "Submit" button, the game checks if the entered guess matches the target pictogram. If the guess is correct, a success message is displayed. Otherwise, an error message is shown and the player can try again.
Note: This is a basic implementation, and you can customize it further with additional features, levels, or scoring mechanisms as per your requirements.
