As an AI language model, I can help you design a basic game using HTML and JavaScript that can be played on a smartphone. Please keep in mind that due to the limitations of this text-based interface, I can only provide you with a basic example of the game structure in plain text format.
To create a simple game, you can try implementing a "Coin Collector" game where players collect coins to earn points. Here's an example code structure using HTML, JavaScript, and pictograms:
In this game, the player simply needs to click the "Collect Coin" button to add points (coins) to their score. The score is displayed on the screen, and a pictogram of a coin (
🪙) is shown for visual representation. You can replace the pictogram with suitable icons or images as per your requirements.
Please note that this is just a basic example, and you can enhance and customize the game logic, graphics, and overall gameplay based on your preferences and requirements.
