Background of SKYFLAG Implementation
Cloud Catcher is an online crane game that launched its service in October 2015 and celebrated its 10th anniversary this year. Online crane games operate on a paid business model where users experience a sense of achievement only after successfully winning prizes through gameplay. Since payment can sometimes act as a barrier to entry for new users, the company initiated reward monetization to lower this threshold by providing a simulated paid experience.
In doing so, they faced challenges with the support system for user inquiries in their previously implemented reward monetization service. Consequently, they transitioned to and implemented “SKYFLAG” in November 2022.
Objectives of SKYFLAG Implementation
- Providing a simulated paid experience for new users.
Challenges Before SKYFLAG Implementation
- Enhancing the support system of the existing reward monetization service.
Results and Outcomes After Implementation
Compared to the reward monetization service utilized prior to implementing “SKYFLAG,” advertising revenue grew by approximately 110% after implementation, establishing a stable revenue foundation. In particular, measures tailored for new users effectively lowered the barrier to entry, resulting in an increase in first-time user conversions and demonstrating a clear expansion in service utilization among new users.
Furthermore, by streamlining “SKYFLAG” operations, the company successfully reduced operational man-hours, allowing operational resources to be allocated to core business tasks. They highly appreciated that by incorporating strategic measures and improvement proposals through regular meetings, they have established a rational operational structure that simultaneously achieves both user retention and profitability.

Effects After Implementation
- Meticulous support systems significantly reduced the operational burden on management.
- Achieved a 110% growth in revenue compared to the previous reward monetization service.
We also interviewed the team regarding the specific utilization measures of “SKYFLAG” to maximize revenue while enhancing the service experience for new users, as well as their methods for balancing user retention and profitability. For details, please read the full interview text.
