How did an ordinary car driving simulator from 5$ become a 72,500€ earner?

Introduction

Gaming income isn’t just about ads anymore. For iOS, up to 40%—and for Android, up to 20%—of total revenue now comes from in-game purchases. As the screenshots show, this project thrives on a balanced mix of IAP and ads across both platforms.

On April 1, 2021, after integrating CAS.AI mediation for the Android version, the results were immediate. Real-time data showed a spike in both active and new users—marking the start of a strong growth trajectory.
