(Strategic Takeaway) {#so-what} Sudoku - Logic Number Puzzles is an entertainment app that is completely free. It holds a 4.74/5 rating from 74 reviews. > **Bottom Line:** Sudoku retains a loyal base through its offline-first design, but the lack of an ad-free monetization tier leaves revenue on the table. Introducing a premium removal option would address the primary user complaint while stabilizing the current ad-supported model. **Best for:** Casual puzzle players seeking brain training and time-killing activities. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship a one-time ad-removal IAP because it is the top-requested user feature → increase ARPU ### Outlook: Stable The casual puzzle market is consolidating around titles with frequent live-ops and feature updates. Sudoku remains stable due to its core mechanics, but the lack of development velocity will likely lead to a gradual decline in new-user acquisition as rivals capture the market share. - 🔴 The 190-day gap since the last store update suggests a maintenance-only cadence, which risks losing visibility to more active category rivals. - 🟢 The 4.74-star rating indicates high satisfaction with the core puzzle mechanics, providing a stable foundation for future monetization experiments. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.74/5 | | Total Reviews | 74 | | Sentiment | Thrilled (90/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Sudoku - Logic Number Puzzles** (this app) | 4.74/5 | Thrilled | 衍旋 廖 | | [JustPlay: Earn Money or Donate](https://marlvel.ai/apps/justplay-earn-money-or-donate) | 4.4/5 | n/a | JustPlay GmbH | | [YouTube TV](https://marlvel.ai/apps/com-google-ios-youtubeunplugged) | 3.7/5 | n/a | Google | | [BestPlay: Play Games & Earn](https://marlvel.ai/apps/bestplay-play-to-earn-donate) | 4.6/5 | n/a | Bestplay | | [BIBLIOTECA LDM](https://marlvel.ai/apps/biblioteca-ldm) | 4.8/5 | Mixed | Esteban Gonzalez | | [DramaBox - Stream Drama Shorts](https://marlvel.ai/apps/dramabox-stream-drama-shorts-1) | 4.7/5 | n/a | STORYMATRIX | ## Company Profile - **Developer:** 衍旋 廖 - **Website:** [https://help.liaoyanxuan.com/](https://help.liaoyanxuan.com/) ## Data Sources & Links - **App Store ID:** 1489801991 - **Google Play ID:** com.liaoyanxuan.sudoku - **Dev Site:** [Official Website](https://help.liaoyanxuan.com/) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*JustPlay: Earn Money or Donate*](https://marlvel.ai/apps/justplay-earn-money-or-donate) (JustPlay GmbH) · 4.4/5 Rating - [*YouTube TV*](https://marlvel.ai/apps/com-google-ios-youtubeunplugged) (Google) · 3.7/5 Rating - [*BestPlay: Play Games & Earn*](https://marlvel.ai/apps/bestplay-play-to-earn-donate) (Bestplay) · 4.6/5 Rating - [*BIBLIOTECA LDM*](https://marlvel.ai/apps/biblioteca-ldm) (Esteban Gonzalez) · 4.8/5 Rating - [*DramaBox - Stream Drama Shorts*](https://marlvel.ai/apps/dramabox-stream-drama-shorts-1) (STORYMATRIX) · 4.7/5 Rating - [*DramaWave - Dramas & Reels*](https://marlvel.ai/apps/dramawave-dramas-reels) (SKYWORK AI PTE LTD) · 4.7/5 Rating - [*PACIFIC RIM: JAEGER VS KAIJU BATTLE*](https://marlvel.ai/apps/pacific-rim-jaeger-vs-kaiju-battle) (Warner Bros.) · 3.5/5 Rating - [*PLAYZONE - Play & Earn Rewards*](https://marlvel.ai/apps/money-well-earn-rewards) (Vanessa Calatayud Gomis) · 2.5/5 Rating - [*TikTok Pro - Events*](https://marlvel.ai/apps/com-ss-iphone-ugc-tiktok-pro) (TikTok Ltd.) · 4.6/5 Rating - [*TikTok - Videos, Shop & LIVE*](https://marlvel.ai/apps/tiktok-videos-shop-live) (TikTok Ltd.) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Sudoku good for beginners?
