Too many ads

There are a lot of ads, but since there's no stamina or time limit, I'm playing with the mindset that I just need to break the puzzles with GEMs embedded. If I press the ×3 thing below the LevelClear screen, I end up having to watch an ad, but I watch it because it slightly increases the GEMs I get, though it's too long. It doesn't seem like I'll finish without playing persistently...
