Sure! Here's an example of a simple merge game implemented as a single HTML file using JavaScript and pictograms:
To play the game, simply copy and paste the above code into a new HTML file, and open the file in a web browser. The game board will be displayed, and you can use the arrow keys on your smartphone's keyboard to merge tiles. The game ends when no further merges are possible, and a message box will appear saying "Game Over".
Please note that this is a very basic implementation of the merge game and can be further enhanced with additional features and graphics.
