10-Year-Old Game App Shukka Buta Sees 10x Sales Via Ad Solution Playtime
The case shows that a mature mobile game can reverse user stagnation and rising acquisition costs by combining ad-based monetization with a point reward system that keeps gameplay central.
Reporting from 1 sources: GameBusiness.jp.
Mobile ad platform adjoe reported that the decade-old game app Shukka Buta, operated by EAGLE, achieved a V-shaped recovery after integrating its Playtime ad monetization solution with a point activity system. Monthly revenue jumped from 11 million yen in June 2025 to 110 million yen in January 2026, and the app entered the Google Play Store top 10 free game rankings.
adjoe presented the Shukka Buta case on June 3 at GAME FUTURE SUMMIT 2026. The app, released in 2015, faced declining engagement and high customer acquisition costs in its 10th year. EAGLE representative Ryuma Hachisu responded by linking in-game missions with adjoe's Playtime ad solution and a point activity system that rewards play. The results included a 9.5x increase in installs while controlling cost per install, and retention rates well above market average (Day 1: 64.7%, Day 30: 14.1%). adjoe plans to use the model to support other mature apps' regrowth.
