Sure! Here's an example of a color merging game implemented as a single HTML file:
In this game, you have a 4x4 grid of cells, and each cell starts with a randomly assigned color. By clicking on a cell, its color will cycle through a predefined set of colors. The goal is to merge adjacent cells into the same color by strategically clicking on them. The game itself does not keep track of scores or any other advanced mechanics, but you can build upon this base to add more features and complexity if desired.
