How Block Blast harvests its players for ad money

Block Blast, a mobile puzzle game, generated an estimated $127 million in ad revenue between January and May 2026—significantly outpacing Candy Crush Saga's $81.1 million over the same period. The game uses a sophisticated system of encrypted JavaScript modules called "traits" and "arms" that are downloaded server-side after installation, allowing developers to remotely control gameplay mechanics and ad delivery without users seeing the full code in the app store. This architecture enables aggressive monetization strategies, with multiple traits designed specifically to harvest ad revenue by manipulating player revive mechanics and advertising placement.
