Sure! Here's a simple game implemented as a single HTML file using JavaScript. The game is called "Emoji Matcher" and it involves matching pairs of emoji icons. It can be played on a smartphone and uses pictograms as requested. Please note that this is a basic implementation and can be further improved and customized based on specific requirements.
Emoji Matcher
Match the pairs of emoji icons!
To use this game, save the above code in an HTML file (e.g., `emoji-matcher.html`) and open it using any web browser on your smartphone. The game will be displayed, and you can start matching pairs of emoji icons by tapping on the cards. Once all pairs are matched, a congratulatory message will appear, and you can reset the game to play again.
Please make sure to save an image called `emozi_all/emoji.png` in the same directory as the HTML file to properly display the emoji icons.
