### 1/5 — Can’t play with out spending money

*2025-02-23, version 1.1.0*

This used to be a fun game, but they changed the way you win from passes to money, when you run out of free money you can’t watch videos to get ahead. It looks like they have purposely made it impossible to get through without spending money to buy passes. Not worth it I will be deleting this app
