With a 4.45/5 rating from 7.9K reviews, it shows mixed user reception. > **Bottom Line:** Lost Pages: Deckbuilder succeeds by replacing luck-based mechanics with deep resource management, but the current connectivity and stability issues are actively draining the player base. Addressing the offline-play friction would unlock the casual mobile segment and stabilize the daily habit. **Best for:** Strategy gamers and roguelike enthusiasts who prefer complex resource-management mechanics over traditional card-based systems. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship offline play mode because connectivity requirements are the top-cited frustration theme → increase retention ### Outlook: Mixed The strategy roguelike market is consolidating around titles that offer seamless, offline-first experiences. Lost Pages: Deckbuilder remains in a maintenance-mode cadence, and without resolving the connectivity and progress-loss friction, the title will likely see continued erosion of its active user base. - 🔴 Frequent mandatory data downloads disrupt the daily play habit, which compounds the churn pressure already visible in the review sentiment. - 🔴 Persistent account-linking failures lead to progress loss, which erodes trust and drives the negative rating trend on the latest version. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.45/5 | | Total Reviews | 7.9K | | Sentiment | Mixed (55/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Lost Pages: Deckbuilder** (this app) | 4.45/5 | Mixed | Jiffycrew | | [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:** Jiffycrew - **Website:** [https://jiffycrew.com](https://jiffycrew.com) - **Social:** [YouTube](https://www.youtube.com/watch) · [Discord](https://discord.gg/wUE3PX69bX) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/lost-pages-deckbuilder/id1574453875?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.Jiffycrew.LostPages&hl=en&gl=us) - **Dev Site:** [Official Website](https://jiffycrew.com) - **Sources:** Developer website content, 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 Lost Pages: Deckbuilder worth playing if I enjoy Slay the Spire?
