 averaging the number of DAUs for each day within that period. We believe DAU is a useful metric to measure the scale and usage of our games on a specific day, and it more accurately reflects player engagement with our games.

(1) Quarterly Average DAU refers to the Average DAU calculated on a quarterly basis, facilitating year-over year comparisons.

The decline in DAU in the Q1 of 2025 compared to the same period in 2024 is mainly due to the impact of the lifecycle rhythm of certain mature products. Among them, “Hammer Explosion Wulin”, “Little Zombie” and “Guardian Domain” are gradually entering the later stage of operation, and investment has been reduced, with a focus on long-term revenue harvesting strategy. In addition, during Q1 and Q2 of the 2024 fiscal year, ‘Nine Sky Spirit Snake Record’ was at its peak of performance, which raised the base for the same period and further amplified the year-on-year decline.

Monthly Paying Users

We define Monthly Paying Users (MPU) as the number of individuals who have made at least one purchase of virtual goods on a specific platform within the 30-day period leading up to the measurement date. According to this metric, an individual who purchases virtual goods in two different games within the same 30-day period is counted as two MPUs. Similarly, an individual who makes purchases on two different platforms, such as Apple iOS or Google Play, for any of our games is counted as two MPUs. The Average MPU for a specific period is calculated by averaging the MPU for each month within that period. We believe that MPU is a useful metric to measure the monetization of our games.
