Sure! Here's an example of an incremental game implemented as a single HTML file with JavaScript enclosed in script tags. This game can be played on a smartphone and utilizes pictograms.
Incremental Game
Click the pictograms to increase your score:
0
In this example, we have created a simple incremental game where the objective is to click on pictograms to increase the score. The score is displayed in a div with the id "counter". Each pictogram image is associated with an onclick event that calls the `increaseScore` function with a specific value.
Whenever a pictogram is clicked, the score is incremented by the value passed to the function, and the updated score is displayed in the HTML using `document.getElementById` and `innerHTML`.
