Micro Grinder. This game is fun in concept but the developers are insatiable when it comes to trying to generate micro transactions. Your "cases" fill up fast so you can't continually play. The ads are numerous with most of them unmuteable. In addition, the game glitches here and screwing up the flow and ruining your streak. I understand that developers need money to exist. And I regularly buy ad-free versions of apps and subscribe to a handful, but this one is on another level.
