I second this! Clicker games are a great introduction to game design!
If you are trying to teach a kid how to build games, go on Scratch (https://scratch.mit.edu) and it should take you about 10 minutes to build the most basic form of a clicker game: place a character on the screen, set a click event, increment a score variable.
And then you can add slightly more logic to make it more interesting. My kids and I put together this slightly more engaging clicker game in only an hour: https://scratch.mit.edu/projects/599845292/
