Sure, here's an example of a simple game called "Mas Generator" implemented as a single HTML file using JavaScript and enclosed in script tags. The game mimics the classic "Simon Says" game and is designed for smartphone operation. It uses pictograms to represent the game's elements.
Please note that this is just a basic implementation to give you an idea. You can enhance and customize it further based on your requirements.
Mas Generator Game
To play the game, simply save the above code into an HTML file (e.g., `mas-generator.html`) and open it in a web browser, preferably on a smartphone. The game will display four colored buttons representing the moves you need to follow. Watch and memorize the sequence of button flashes, and then try to repeat it by tapping on the corresponding buttons. If you make a wrong move, the game will end, and you will lose.
