Case Study: Four Thirty Three boosts mobile game revenue by 15% with Google AdMob

Four Thirty Three uses AdMob to boost mobile game revenue by 15%

Four Thirty Three, a global mobile game publisher, faced the challenge of increasing revenue for its hit title Boxing Star without cannibalizing in-app purchases or harming the player experience. To address this, the studio partnered with Google AdMob (and used Google Analytics for Firebase) to explore hybrid monetization through ads that would target engaged players while preserving an ad-free experience for those at risk of churning.

Four Thirty Three implemented Google AdMob’s rewarded video ads, linked AdMob with Google Analytics for Firebase to segment users and optimize ad frequency and rewards (offering non-IAP items and instant prizes), and tested only engaged players to protect retention. The result: total revenue rose 15%, session duration increased 38% (about 5 minutes), retention improved 8%, and over 60% of daily active users opted into rewarded ads—exceeding the team’s 5% revenue goal.
