Hidden Quest

You get 1-3 ads per round, and as you go higher, you absolutely cannot clear it without ads. Also, the more you go up, the more ads you see per round. Most ads are about 45 seconds to 1 minute long. There are so many ads it's infuriating, so I don't recommend it. Honestly, time quests only give like 500 gems, which is trash, so don't do them unless the time quest gives a lot. lol
