Sure! Here's an example of a simple game based on Pascal's Triangle, implemented as a single HTML file using JavaScript. It can be played on a smartphone and uses pictograms for the triangle.
When you open this HTML file in a web browser or a smartphone's browser, it will display Pascal's Triangle with 8 rows using a table structure. Each number in the triangle is represented by a cell in the table. You can customize the number of rows by changing the parameter passed to the `generatePascalsTriangle()` function.
Feel free to modify the code or add additional functionalities to turn it into a game based on Pascal's Triangle.
