Sure, I can help you create a simple merge game using JavaScript and pictograms for smartphone operation. Here's an example code implemented as a single HTML file:
Merge Game
Score: 0
This code sets up a basic merge game where you have to swipe (left, right, up, or down) to merge the numbers on a grid. The game ends when there are no more possible moves. The score is displayed at the top. Each time you swipe, new numbers (either 2 or 4) will appear randomly on the grid. The goal is to merge numbers until you reach the highest possible number.
