Case Study: Balloon Island achieves 150% revenue growth with Google AdMob

Balloon Island grows revenue 150% with AdMob

Balloon Island, a Hong Kong–based mobile gaming studio founded by Tenny Woo with over 1 million downloads of titles like Ultimate Jewel and the Lollipops series, needed a global partner to monetize rapid growth without hurting player experience. The team chose Google AdMob for its support and worldwide reach to help maximize in‑app ad revenue while keeping gameplay engaging.

Using Google AdMob’s banner and interstitial ad formats plus AdMob Mediation to optimize demand, Balloon Island balanced monetization with user experience and scaled its ad operations. The result: revenue grew 150% and ad inventory increased to more than 4 million units daily, supporting the company’s continued growth.
