Sure! Here's a simple game implemented as a single HTML file using JavaScript. It can be played on a smartphone and uses pictograms.
This game is a simple pictogram matching game where the player needs to find pairs of matching pictograms. The player can tap/click on any pictogram on the canvas to flip it and reveal its symbol. If two flipped pictograms match, they remain visible, otherwise, they are hidden again. The game continues until all pairs are matched.
To play the game, simply copy the above code into a new HTML file on your iOS device, open it in a browser, and the game will start automatically. Enjoy!
