Problematic Levels: Specific levels with low completion rates and high churn were identified, particularly those with difficult difficulty curves or requiring excessive booster usage. Leaderboard Feature Impact: While the leaderboard increased DAU and revenue, its ARPDAU slightly decreased, indicating that the feature did not significantly impact player spending. AB Test Results: The pricing change in the AB test resulted in a modest increase in total revenue (+8.4%) and ARPU, validating the hypothesis that lowering prices could increase conversions.
