Can be done in 40 mins without ads (Recommended)

If you turn on airplane mode, you can clear the game without watching a single ad. Every time you clear a stage, a network error popup appears, but if you close the app from the background and reopen it (no need to toggle airplane mode on/off), you can start the next level. Although exiting and re-entering the game after each stage is a bit tedious, it's better than watching ads, and it took me 40 minutes to reach level 60. Up to level 15, short ads of about 10 seconds played after each stage, so I watched them, but after that, ads started appearing even during gameplay, so I used airplane mode. It's a matching game, so it's easy and simple, requiring no brainpower. You can clear it so easily that you don't even need to use items. Considering how many games these days force you to use items due to ad incentives, this game is a godsend.
