Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript. Since you mentioned smartphone operation and 3D screen, let's create a basic 3D puzzle game using pictograms.
In this example, we create a canvas element where the game will be rendered. We define an array of pictograms with their respective positions. The `loadImages` function is responsible for loading the pictogram images. Once all the images are loaded, the `startGame` function is called, which can include the game logic.
In this case, we simply draw the loaded pictograms on the canvas using the `drawImage` method. You can modify the game logic and add interactivity using JavaScript to make it a playable game.
