<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [INVEST] Ship a bug fix for profile-saving settings because it is a top-cited frustration theme → improve retention
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Declining

The casual card game market is consolidating around titles with active live-ops and stable UI, leaving 31 Card Game - Thirty One exposed due to its stagnant development cadence. Without addressing the core technical bugs and ad-frequency complaints, the app will continue to lose its remaining user base to more responsive competitors.

- 🔴 The lack of updates since 2020 prevents the app from addressing user-reported bugs, which compounds the negative sentiment already visible in the 1.2-star rating.
- 🔴 Excessive ad frequency between game rounds drives user churn, as the current monetization model prioritizes short-term ad inventory over long-term player retention.
