Disruptive Ad Timing: Injects unskippable interstitial ad rolls mid-session, completely halting active puzzle gameplay.
The Tutorial Bait-and-Switch: Runs completely clean and ad-free during the first two minutes to pass store retention metrics before opening the ad floodgates.

Forcing video ad breaks while a player is actively strategizing moves ruins the game feel and violates Google's core Disruptive Ads guidelines.
