Hey! I'm trying to come up with a similar daily puzzle game, did anything help you come up with the idea? Also, do you generate these unrelated words daily and then vet them before releasing the daily puzzle, or is it all pretty much automated?

As for Enlinko, it's hard game to balance. That's why i've made three difficulty levels. As for daily puzzles, i'm now using semi automated generator - it generates lot of pairs, try to solve them, check if solution counts match some rules and then i'm hand picking those potential pairs for daily puzzles.
