Sure! Here's an example of a simple game similar to Combat Master that you can play with friends using a WiFi connection. The game uses pictograms for graphics. You can save the code as an HTML file and open it in a web browser to play.
To play the game:
1. Open the HTML file in a web browser on your smartphone.
2. Enter the number of players (2-7) and press "OK".
3. The game will start, and each player should take turns attacking another player by tapping on their corresponding option.
4. The game will notify you of each attack and when the game is over.
Note: This is a very basic implementation of a game and can be expanded upon to add more features, graphics, and gameplay mechanics.
