Maintenance-mode updates leave the app exposed: a single live-ops rival with a more stable, offline-first experience will erode the current chart lead before the next major drop. - 🔴 The latest update introduced aggressive ad frequency, which disrupts short gameplay sessions and triggers negative sentiment. - 🔴 Forced online connectivity requirements prevent offline play, causing users to uninstall the app due to limited data access. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.54/5 | | Total Reviews | 3.9K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Hamdoku: Sudoku Logic Puzzle** (this app) | 4.54/5 | Mixed | mobirix | | [Pixel Flow!](https://marlvel.ai/apps/pixel-flow-1) | 4.6/5 | Excited | Loom Games A.Ş. | | [スイートホームメイド【スイメド】](https://marlvel.ai/apps/com-dmm-games-sweethomemaid) | 4.5/5 | N/A | DMMGAMES | | [12 Locks Funny Pets](https://marlvel.ai/apps/com-rud-twelvelockspets) | 4.3/5 | N/A | RUD Present | | [15 Puzzle (Game of Fifteen)](https://marlvel.ai/apps/15-puzzle-game-of-fifteen) | N/A/5 | N/A | Sylvain Saurel | | [15 Puzzle Pro](https://marlvel.ai/apps/15-puzzle-pro) | N/A/5 | N/A | Sylvain Saurel | ## Company Profile - **Developer:** mobirix - **Website:** [https://www.mobirix.com](https://www.mobirix.com) - **Social:** [Facebook](https://www.facebook.com/mobirixplayen) · [YouTube](https://www.youtube.com/user/mobirix1) ## Data Sources & Links - **App Store ID:** 6795797684 - **Google Play ID:** com.mobirix.hamdoku - **Dev Site:** [Official Website](https://www.mobirix.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Pixel Flow!*](https://marlvel.ai/apps/pixel-flow-1) (Loom Games A.Ş.) · 4.6/5 Rating | Positive Sentiment - [*スイートホームメイド【スイメド】*](https://marlvel.ai/apps/com-dmm-games-sweethomemaid) (DMMGAMES) · 4.5/5 Rating - [*12 Locks Funny Pets*](https://marlvel.ai/apps/com-rud-twelvelockspets) (RUD Present) · 4.3/5 Rating - [*15 Puzzle (Game of Fifteen)*](https://marlvel.ai/apps/15-puzzle-game-of-fifteen) (Sylvain Saurel) · N/A Rating - [*15 Puzzle Pro*](https://marlvel.ai/apps/15-puzzle-pro) (Sylvain Saurel) · N/A Rating - [*2048 Blocks 3D - Merge Numbers*](https://marlvel.ai/apps/2048-blocks-3d-merge-numbers) (Clogica) · N/A Rating - [*2248 Blast: Merge Puzzle*](https://marlvel.ai/apps/2248-blast-merge-puzzle) (Adaric Music) · 4.8/5 Rating - [*2k48 - 4 puzzle modes*](https://marlvel.ai/apps/2k48-4-puzzle-modes) (Loop Games) · 3.4/5 Rating - [*2 Player Games: Tic Tac Toe*](https://marlvel.ai/apps/2-player-games-tic-tac-toe) (BiBoGames) · N/A Rating - [*3D Colorful Sort™ Magic Water*](https://marlvel.ai/apps/3d-colorful-sort-magic-water) (Gaming Laboratory) · 4.8/5 Rating ## Frequently Asked Questions {#faq} ### Is Hamdoku suitable for players who struggle with Sudoku numbers?
