As an AI text-based model, I can provide you with a basic example of a game implemented as a single HTML file using JavaScript. Please note that this example is not an actual GTA 6 game, as it would be a complex and large-scale project. Nonetheless, here's a simple rock-paper-scissors game that you can play on a smartphone:
Rock-Paper-Scissors
Make your choice!
In the example above, upon opening the HTML file, you will see the rock-paper-scissors game interface on your smartphone screen. By tapping on one of the pictograms (rock, paper, or scissors), the game logic will determine the winner and display the result below the choices.
Please note that to make this example game more visually appealing and interactive, you would need to replace the image sources (`emozi_all/game.png`, `emozi_chicken.png`, `emozi_all/scissors.png`) with appropriate pictograms and improve the styling according to your preferences.
