Case Study: Change the World Inc achieves 150% of its D30 ROAS goal with Unity's Tapjoy

How CTW scaled their HTML5 game, exceeding their D30 ROAS goal by 150% with Tapjoy from Unity

Change the World Inc (CTW), Japan’s leading IP game platform company, wanted to scale its HTML5 title Vivid Army and reach more high-value users on its G123 platform. To expand its user acquisition strategy, CTW worked with Unity and Tapjoy from Unity, using CPA campaigns to drive new engagement and conversions.

Unity recommended launching Tapjoy CPA campaigns and helped CTW optimize conversion goals, bids, and geos through offerwall dashboards and strategic guidance. The result was 4x higher ROAS than non-reward-based advertising channels and D30 ROAS performance that exceeded the goal by 150%, leading CTW to expand CPA campaigns to 15 additional titles.
