With a 4.52/5 rating from 3.8K reviews, it delivers strong user satisfaction. > **Bottom Line:** Crazy Bishop retains core users through granular ELO scaling, but the lack of recent updates leaves the app vulnerable to rivals with active live-ops, which will eventually erode the current rating baseline. **Best for:** Chess players ranging from beginners to advanced users seeking a tool for skill development and game analysis. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit performance on legacy hardware because user complaints flag stuttering on older devices → improve retention ### Outlook: Stable The casual chess market is consolidating around apps with frequent content updates and social features. Crazy Bishop remains stable due to its core engine, but the lack of recent development will likely result in a slow decline in new-user conversion as competitors offer more modern interfaces. - 🔴 The 854-day update gap signals a maintenance-only posture, which will likely lead to gradual user attrition as competitors introduce modern live-ops features. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.52/5 | | Total Reviews | 3.8K | | Sentiment | Thrilled (90/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Crazy Bishop** (this app) | 4.52/5 | Thrilled | UNBALANCE Corporation | | [Royal Match](https://marlvel.ai/apps/royal-match) | 4.7/5 | n/a | Dream Games | | [Archero](https://marlvel.ai/apps/archero) | 4.5/5 | N/A | HABBY | | [Bejeweled Blitz](https://marlvel.ai/apps/bejeweled-blitz) | 3.3/5 | n/a | PopCap | | [Bingo Cash - Win Real Money](https://marlvel.ai/apps/bingo-cash) | 4.7/5 | Excited | Papaya Gaming | | [Brawl Stars](https://marlvel.ai/apps/brawl-stars) | 4.5/5 | n/a | Supercell | ## Company Profile - **Developer:** UNBALANCE Corporation - **Website:** [https://www.unbalance.co.jp/english/](https://www.unbalance.co.jp/english/) - **Social:** [X/Twitter](https://twitter.com/unbalance_jp) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/crazy-bishop/id497640483?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=jp.co.unbalance.android.chess_free&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.unbalance.co.jp/english/) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Royal Match*](https://marlvel.ai/apps/royal-match) (Dream Games) · 4.7/5 Rating - [*Archero*](https://marlvel.ai/apps/archero) (HABBY) · 4.5/5 Rating - [*Bejeweled Blitz*](https://marlvel.ai/apps/bejeweled-blitz) (PopCap) · 3.3/5 Rating - [*Bingo Cash - Win Real Money*](https://marlvel.ai/apps/bingo-cash) (Papaya Gaming) · 4.7/5 Rating | Positive Sentiment - [*Brawl Stars*](https://marlvel.ai/apps/brawl-stars) (Supercell) · 4.5/5 Rating - [*Hole.io*](https://marlvel.ai/apps/hole-io) (Voodoo) · 3.9/5 Rating - [*Partymasters - Fun Idle Game*](https://marlvel.ai/apps/partymasters-fun-idle-game) (AI Games FZ) · 4.5/5 Rating | Positive Sentiment - [*Temple Run*](https://marlvel.ai/apps/temple-run) (Imangi Studios, LLC) · 4.3/5 Rating - [*YouRiding - Surf and Bodyboard*](https://marlvel.ai/apps/youriding-surf-and-bodyboard) (BoardScore, Inc.) · 4.2/5 Rating - [*Agar.io*](https://marlvel.ai/apps/agar-io) (Miniclip.com) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Crazy Bishop suitable for beginners?
