With a 4.83/5 rating from 12 reviews, it shows polarized user reception. > **Bottom Line:** The app retains a loyal niche audience through its focused 'Ten Puzzle' format, but the lack of daily retention loops leaves it vulnerable to modern rivals, so the PM should prioritize a daily challenge mechanic to secure recurring engagement. **Best for:** Students and puzzle enthusiasts seeking brain training or casual intellectual stimulation. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship daily challenge streak mechanic because static content lacks retention loops → increase daily active users — *Competitor Math Cross uses daily challenges to drive consistent retention compared to our static model.* _(trade-off: deprioritize Pause the development of additional puzzle stages — current 552-problem set is sufficient for the current user base.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Implement hint system because users churn on difficult puzzles → improve completion rates — *Competitor Number Puzzle - Cross Math uses hints to reduce churn on difficult segments.* _(trade-off: deprioritize Deprioritize UI visual refresh — functional retention improvements take precedence over aesthetic updates.)_ ### Feature Gaps vs Competitors - Daily challenges (available in Math Cross but absent here) - Difficulty scaling (available in Math Cross but absent here) - Global leaderboards (available in Hidden Numbers but absent here) - Hint system (available in Number Puzzle - Cross Math but absent here) ### Outlook: Stable The casual math puzzle market is consolidating around live-ops-heavy titles that prioritize daily retention over static content libraries. Without a shift toward daily engagement loops, this app will continue to lose share to competitors that offer infinite, randomized, or time-gated challenges. - 🔴 Static content model without daily updates leads to user fatigue, which accelerates churn compared to rivals with daily challenge loops. - ⚪ The latest update focused on stability, indicating the app remains in maintenance mode rather than active feature expansion. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.83/5 | | Total Reviews | 12 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **数学クイズ Make10** (this app) | 4.83/5 | N/A | StudySwitch, Inc. | | [Math Cross - Math Puzzle Games](https://marlvel.ai/intel-report/games/math-cross-math-puzzle-games) | 4.8/5 | Mixed | BIGLIME LIMITED | | [Math Puzzle Game - Crossword](https://marlvel.ai/intel-report/games/math-puzzle-game-crossword) | 5.0/5 | N/A | sohil kadevar | | [PrimeXTime](https://marlvel.ai/intel-report/games/primextime) | 5.0/5 | N/A | Rick Hutchinson | | [Merge Number Block: Get Prizes](https://marlvel.ai/intel-report/games/merge-number-block-get-prizes) | 4.4/5 | N/A | puzzle studio | | [Number Puzzle - Cross Math](https://marlvel.ai/intel-report/games/number-puzzle-cross-math) | 5.0/5 | N/A | SnapJoy Co., Limited | ## Company Profile - **Developer:** StudySwitch, Inc. - **Website:** [https://www.studyswitch.co.jp/?appstore](https://www.studyswitch.co.jp/?appstore) - **Social:** [Facebook](https://www.facebook.com/391154754640977?ref=embed_page) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/%E6%95%B0%E5%AD%A6%E3%82%AF%E3%82%A4%E3%82%BA-make10/id878908923?uo=4) - **Dev Site:** [Official Website](https://www.studyswitch.co.jp/?appstore) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*Math Cross - Math Puzzle Games*](https://marlvel.ai/intel-report/games/math-cross-math-puzzle-games) (BIGLIME LIMITED) — 4.8/5 Rating | Mixed Sentiment - [*Math Puzzle Game - Crossword*](https://marlvel.ai/intel-report/games/math-puzzle-game-crossword) (sohil kadevar) — 5.0/5 Rating | N/A Sentiment - [*PrimeXTime*](https://marlvel.ai/intel-report/games/primextime) (Rick Hutchinson) — 5.0/5 Rating | N/A Sentiment - [*Merge Number Block: Get Prizes*](https://marlvel.ai/intel-report/games/merge-number-block-get-prizes) (puzzle studio) — 4.4/5 Rating | N/A Sentiment - [*Number Puzzle - Cross Math*](https://marlvel.ai/intel-report/games/number-puzzle-cross-math) (SnapJoy Co., Limited) — 5.0/5 Rating | N/A Sentiment - [*Extreme Math True Or False : The Addition and Subtraction Puzzle Free Game*](https://marlvel.ai/intel-report/games/extreme-math-true-or-false-the-addition-and-subtra) (Thanagorn Marukcanon) — 3.3/5 Rating | N/A Sentiment - [*HueSnap!*](https://marlvel.ai/intel-report/games/huesnap) (YONGJUN LEE) — N/A Rating | N/A Sentiment - [*Number Wave: Cosmic Math Grid*](https://marlvel.ai/intel-report/puzzle/number-wave-cosmic-math-grid) (MSP Universe) — N/A Rating | N/A Sentiment - [*Hidden Numbers: Math Game*](https://marlvel.ai/intel-report/games/hidden-numbers-math-game) (Michal Sajban) — 5.0/5 Rating | N/A Sentiment - [*Flashcards maker - AI generate*](https://marlvel.ai/intel-report/education/flashcards-maker-ai-generate) (Teleprompter LLC) — 4.1/5 Rating | Mixed Sentiment ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** — Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** — Identifies the app's core features, monetization model, target audience, and competitive positioning.
