Sure! Here is an example of a basic merge game implemented as a single HTML file using JavaScript:
Merge Game
Click on the squares to merge them!
Score: 0
In this game, there are three square elements displayed in a row. By clicking on each square, the numbers displayed inside them are merged. Initially, each square contains the number 0. When a square is clicked, if its current value is 0, it changes to 2. If the current value is not 0, it doubles the value and updates the score accordingly.
I hope this helps! Let me know if you have any further questions.
