A Game for Hidden Quests

I installed this game because it was better than the main quest. It's an idle game, but it requires simple operations like merging goblins to level them up, moving them to other rocks after smashing them, and tapping to collect coins and treasure chests. If you log in frequently during times other than the main quest, perform simple operations, and then close the game, it's an efficient game where you can get large gems from hidden quests. I realized this yesterday while clearing Mine 7. Since I was only playing during the main quest, with only 3 days left for hidden quests, 10 seems to be my limit. This game is not about earning money through the main quest. If you're just starting, I recommend logging in outside of main quest times to aim for the hidden quests.
