More and more levels with 20 moves, seems like lazy design to me. Monitor the progress of players who get the levels early, reduce those levels that are won too quickly to 20 moves. At least it’s a “tell” - a lot of those boards with 20 moves are impossible without extra moves so I’ll just wait around until they increase…
Glad to see I’m not the only one who thinks 10489 is not possible - I don’t believe the numbers work either (a post upthread does the math). I know we’re all used to hearing “all levels are possible without boosters,” but I’m seriously doubting it here. I’ve gotten down to needing 5 or fewer icing/toffee quite a few times…
