During initial testing, Bingo Tour’s user acquisition results began to exceed benchmarks within the first three days of testing on Unity User Acquisition. This led the Wawayu team to expand their launch to multiple paid channels.

Increasing their reach created challenges with balancing bids, traffic, and cost per install (CPI), limiting their ability to bring in quality users at scale. They were finding that if their bids were low, then ROI would meet their standards but the traffic would be lower. Even after increasing bids, ROI would decrease.

These factors prompted Lei to search for a better solution to take Bingo Tour to the next level.

Wawayu turned to Unity User Acquisition’s ROAS campaigns to help attract users with varying LTVs from a wide database. It then reasonably bids for them to achieve a target ROI. By running ROAS-optimized campaigns, they were able to increase their D7 ROAS by 39% and D7 retention by 31%.

The campaign optimization also helped free up team bandwidth, since all they needed to do was set a target ROI, and the ROAS campaign would automatically find the balance between ROI and spend.

Lei explains, “With Unity’s diverse campaign optimization types and precise machine learning, it is one of our critical channels for user acquisition.”

By using ROAS campaigns, Wawayu was able to achieve their target ROI without worrying about a higher CPI. ROAS campaigns also helped provide a shorter window for testing and learning since they supported both D0 and D7 optimization windows.

At first, the team took a conservative approach to running ROAS campaigns. But once performance started to pick up, the quality of acquired users they were getting far outweighed the slightly higher cost of acquisition, which led them to increase their campaign spend by 10x.

“Although the cost of ROAS campaigns is higher than that of install campaigns, the overall user quality and monetization revenue have seen a significant year-over-year increase,” says Lei. “We’ve achieved more spending with a steady and sustainable return rate. We highly recommend this solution to any mobile game developer.”

The Wawayu team worked closely with their Unity account team to help scale Bingo Tour. Unity recommended different settings, bids, and optimization suggestions for different promotional periods. This partnership led to campaign ROI that’s continuously improving.

When speaking about the collaboration, Lei says, “The team provides a detailed quarterly report with in-depth analysis, and they are always open to feedback from publishers for continuous improvement. Unity has been a delightful long-term partner for us.”
