If you return you are forced to look at ads for at least 2 minutes. I would be fine if there was an option to pay and go ad free. ### 3/5 — Great game but keeps muting my audio *2025-09-08* I love playing this game to relax but I also always have an audiobook, podcast or music playing in the background. This app for some reason always makes my other audio stop playing which means I end up leaving the game and playing something else so I can keep listening. ### 4/5 — Frustrated *2024-10-03, version 3.5.0* I love this game, but Please remove the Toyota Camry ad. It locks my iPad every time, forcing me to restart my iPad. Very frustrating. ### 2/5 — Fine puzzle *2024-09-23, version 3.5.0* Too many ads. Find another one ### 1/5 — Latest update *2024-09-17, version 3.5.0* Latest update now has ads/breaks right in the middle of playing. So stupid. I can deal with the ads after finishing a puzzle, but now, it’s just ridiculous. ### 2/5 — うーん *2024-09-13* ちょっとした隙間時間に毎日数問遊んでたけどアプデしたらゲームの最中にも広告入るようになって一気に冷めました **Developer response:** こんにちは。広告が煩わしいようで申し訳ありません。私たちは広告と無料かつ楽しいゲーム体験のバランスを取るよう努めています。一部の広告は 5 秒後にスキップできます。また、お客様のフィードバックを開発チームに転送し、ゲームの最適化を継続します。他に何かございましたら、killersudoku@fungame.studio までご連絡ください。ご協力ありがとうございます。 - Melody ### 2/5 — Ads are too annoying! *2024-09-01, version 3.4.1* I like Killer Sudoku as a step up from regular Sudoku. However, the frequent and overly long ads in this app have made me decide to uninstall the game. 😟 ### 5/5 — Сыграла пока пару тройку игр *2024-08-17* Пока всё отлично, рекламы в меру) Процветания игре! ### 1/5 — Randomly opening tracking pages *2024-06-05* All of a sudden I noticed that I will be in the middle of playing when my browser pops open with a page I never asked for. I am not even clicking on an ad. I will be in the process of playing and it switches. Beware! I don’t know who it is sending data to. This used to be a great company. I have been playing their regular sudoku for years. **Developer response:** Hi, we are very sorry for the inconvenience caused. Could you please send killersudoku@fungame.studio a screen recording or a video regarding the issue you mentioned? It would be really helpful for us and we will try our best to make the game right for you! If anything else, please also feel free to contact us. Thanks for your understanding and patience! :-) - Melody ### 5/5 — Best game ever!!!!!!!! *2024-01-18* So fun ## Most critical reviews (10 lowest-rated) ### 1/5 — 広告が終わらない *2026-05-25* 広告で何分待たせるつもりなの！？ 頭おかしいのか？ ### 1/5 — Poorly Programmed Ads *2025-09-11* This app turns off my music at random because its ads are poorly scripted. The timer sometimes runs during ads, giving inaccurate times. Lacks a dedicated button to switch on fast entry (you have to press and hold any number). This is nothing special compared to other killer sudoku apps, so you should use one without these problems. ### 1/5 — Ads ads and more ads every time you breathe *2025-08-10* Kill me now. The second an ad for another app appears; I’m out! Game deleted **Developer response:** Hi, sorry about this issue. Could you please kindly take a screen recording or a video regarding the whole process of the issue, and send it to killersudoku@fungame.studio? It would be very helpful for us to locate the issue and make the game right for you. Thank you very much for the support! :-) - Sarah ### 1/5 — “Scanning Your Device” Background Ad *2025-07-17, version 3.9.0* Whatever ads you are allowing on your game are running in the background and playing an OBNOXIOUSLY loud beeping and saying it’s scanning my phone when the app is open. It wakes up my child, which is the only time I can play, pauses my show, and makes me genuinely uncomfortable. Remove the ads or you’ll lose downloaders. ### 1/5 — Werbung nervig, Steuerung kompliziert *2025-07-10* Nach jedem Spiel Werbung ist einfach nervig. Auf den Schnickschnack mit automatischer Kontrolle etc. könnte ich gut verzichten wenn ich dafür wie auf Papier mit dem Pen schreiben und radieren könnte. ### 1/5 — Great game,but the ads get stuck *2025-03-23, version 3.7.0* Love the challenge of this. Big Game Poker ad is frozen every time it comes up! Can not exit it, can not wait it out, can not tap tap tap out of it. Only way out is to delete your app! ### 1/5 — Are you kidding me *2024-10-03, version 3.5.0* I’ve had this game for 4 years. Suddenly there’s ads in the middle of the game, even if you didn’t pause. Interrupts anything I was doing and just makes me leave the app and do something else. Not an app for user experience anymore, just shamelessly trying to make money. ### 1/5 — Ads interrupt game *2024-09-25, version 3.5.0* I’ve had this app for a few years and really enjoyed playing it. However, with its latest update, it is now populating an “ad break” in the middle of my game. I do not want to be interrupted in the middle of playing for some stupid ad. And I REALLY don’t want to be interrupted TWICE during a game that takes me about 8 minutes to complete. ### 1/5 — Ad breaks *2024-09-20, version 3.5.0* The ads after games or to get another hint are fine, but ad breaks, especially MULTIPLE, during games are obnoxious and ruin the app for me. ### 1/5 — Don’t download *2024-09-19, version 3.5.0* They force ad popups mid game. Completely ruins the experience. TERRIBLE. ## Most praised reviews (10 highest-rated) ### 5/5 — Killer sudoku *2026-06-19, version 3.12.0* Love it..
