If are using Android, it's easy to block these ads with apps like Netguard or even PCAPDroid

Then can use the game without annoyance of ads

As it happens, the data collection, surveillance and ad serving strategies of the mobile OS vendors and their unpaid "app developer" independent contractors are still subservient to application firewalls and/or user-controlled DNS

This could change one day, it's within the control of the mobile OS vendors, but I have been waiting over 15 years and it still hasn't

In a lot of these games you need the 'coins' you get from watching the ads to progress.
