Sure! Here's a simplified version of the Rummy card game implemented as a single HTML file, including JavaScript code. Please note that this implementation does not include all the rules and features of a complete Rummy game but provides a basic structure to get you started:
You can copy the entire code and save it as an HTML file (e.g., `game.html`). When you open the file in a browser or on a smartphone, it will display a Rummy game interface. You can click on the "Draw" button to draw a new card and click on a card in your hand to discard it. The discarded card will appear in the "Discard" area. Please note that this implementation is fairly minimal and only includes basic functionality.
