Have you tried Little Alchemy? https://littlealchemy.com/

Back in the early aughts, I had an idea for a digital card game where you battled people with elements that could combine in this way, and you could play your cards on someone else's and change what they had. I never did anything with it, but it's fun to see other people playing around with it.
The funniest combo I made with Infinite Craft is combining "lizard" with "car" gave me "gecko" -- that's some smart, hilarious programming.

Oh no. This is terrible. I might have gone too far. I made Batkid. https://kottke.org/23/11/0043461-remember-batkid-10-years-

Took me an awhile…. But I finally got to sharknado

Oh jeez. I made an anticorn.

I'm so impressed with this. Basic concept, but super fun. I came back to it today and managed 4 "first discoveries". If those are actually instances where no one has found those, I'm more impressed at the entries he's put together for this.
Only downside is now I don't want to close the window and have to start all over again.
