Case Study: Gram Games achieves 4x installs with Unity Tapjoy CPE ads and Per-App Bidding

Gram Games sees 4x installs with Tapjoy CPE ads & per-app bidding

Gram Games, a mobile game publisher behind hits like Merge Dragons! and Merge Magic!, wanted to scale user acquisition while maintaining strong ROAS across key markets. Working with Unity’s Tapjoy platform, the team focused on finding a more efficient way to run cost-per-engagement (CPE) campaigns and improve performance beyond their existing level-completion offers.

Unity helped Gram Games implement Tapjoy CPE campaigns with Per-App Bidding (PAB), allowing the publisher to optimize bids at the individual app level and target higher-quality traffic. This approach delivered major gains, including 4x more user installs and a 132% increase in conversions, while helping Gram Games push high-performing sources and reduce spend on lower-performing ones.
