Sure, I can help you create a simple merge game using JavaScript enclosed in script tags within a single HTML file. The game will be optimized for smartphone operation and will utilize pictograms. Here's an example implementation:
Score: 0
This implementation provides a basic merge game grid with swipe gestures for merging and sliding cells. The player's score is displayed, and the game ends when there are no more available moves. The gameboard consists of 16 cells in a 4x4 grid, and the goal is to merge cells with the same value to reach the highest possible score.
