Abstract: User retention is a critical concern for online gaming platforms. This talk focuses on understanding and predicting player retention in online poker games by characterizing user behaviors and developing predictive models. The study examines two types of games available on the platform: cash games and tournaments with entry fees. Through exploratory data analysis, the user journey and behavior patterns are explored using historical online poker playing data. Key actions, such as deposits, withdrawals, and game participation, are analyzed to gain insights into user attitudes and preferences.
The analysis reveals that the level of deposits and buy-ins varies among users, reflecting their risk-taking propensity and investment in the game. The monthly retention rate fluctuates around 50%, indicating that approximately half of the players from the previous month leave the platform. Moreover, users with longer tenure exhibit higher retention rates, eventually converging at around 87%. Noteworthy correlations between retention and user actions are identified, such as the positive relationship between retention and deposit intensity and frequency, as well as the increased likelihood of retention among users who engage in both cash games and tournaments.
Based on the exploratory analysis, relevant features for building the retention model are selected, including game types, tournaments played, cash buy-ins, deposits and withdrawals, and guaranteed prize pools won. Logistic regression is employed as the modeling technique due to its interpretability and simplicity to prevent overfitting. The model results demonstrate that deposit amount, the number of cash games and tournaments played, and the guaranteed prize amount positively impact player retention. Notably, in tournament games, players who pay entry fees are more likely to be retained compared to free players. Conversely, for cash games, the buy-in level does not correlate with higher retention, as players with varying buy-ins exhibit similar retention rates.
The talk concludes by offering recommendations for player retention based on the data analysis and modeling outcomes, as well as presenting ideas for future research. Although the study employs data from an online poker platform, the analytical methods and models can be applied to other types of games as well.
