Sure! Here's an example of a simple merge game implemented as a single HTML file using JavaScript and enclosed in script tags:
Merge Game
This implementation creates a merge game where you combine the same numbers together by moving them to the left or right using the arrow keys. Each move merges adjacent numbers of the same value, and the aim is to reach the highest score possible by merging as many numbers as you can. The game will start with two random numbers (either 2 or 4) and display the current score on the screen.
Note that this is a basic implementation to give you an understanding of how a merge game could work. You can further enhance it by adding more features, such as winning conditions, different levels, or even animations.
