Detective Riddles. Sherlock's Heritage 2 Free is a games app that is free with in-app purchases.
It holds a 2.5/5 rating from 2 reviews.

<!-- speakable-start -->
> **Bottom Line:** Detective Riddles offers a functional nonogram experience, but its punitive restart logic and lack of updates since 2015 alienate users, so the developer must soften the error penalty to stabilize retention.
<!-- speakable-end -->

**Best for:** Casual puzzle gamers interested in logic-based grid challenges and detective-themed narratives.

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

- [ ] [INVEST] Implement a three-mistake error buffer because users report frustration with single-mistake restarts -> improve session retention
<!-- /section:pm-actions -->

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

The casual puzzle market is consolidating around titles with frequent live-ops and social retention loops. Detective Riddles remains in maintenance-mode, leaving it exposed to modern competitors that offer more forgiving gameplay and regular content drops.

- 🔴 The lack of updates for over 134 months prevents the app from competing with modern puzzle titles that offer live-ops and social features.
- 🔴 User frustration regarding the strict penalty system and monetization pressure signals a high churn risk that the current stagnant development cycle cannot address.
