Recently you’ve started ads right in the middle of play. This is disruptive and annoying and if you don’t fix it I’m out ### 3/5 — If you don’t watch the ads, your winning games will turn into loses *2026-06-20, version 3.5.5* Very greedy ### 4/5 — Recent changes *2026-06-01, version 3.5.1* Loved this game because it only gave advertisements between games. I wouldn’t mind several (3?) between games. Now doing a killer it breaks away every couple of minutes while you are trying to think. I may continue to do the daily but am looking for a different app now. ### 4/5 — Excellent game, recently fewer adds? *2026-04-20, version 3.4.1* Edit… I previously marked this low, despite being addicted to the killer game, due to frequent and lengthy adds… recently they seem less frequent and many are relatively quick, hence 4* ….. This is the best of the killer sodoku’s, I’ve been playing it a few times day, but the adds are driving me nuts, some take a minute, some get stuck and the app has to be restarted… only to get a new add. I’m off to try other apps instead Ps thanks for the reply, have an extra star, I still use it but not as much as I still hate the ads and it’s too expensive to buy ### 2/5 — Privacy-settings misleading *2026-04-13* The game itself is ok but you cannot switch off „legitimate interest“ in the settings. Or more precisely, you can switch it off and save. But the next time you open the privacy settings everything is turned on again. ### 2/5 — Вылетает без сохранения! *2026-03-30* Игра стала вылетать постоянно без сохранения, работает 1-3 мин и вылетает Это моя любимая игра, исправьте пожалуйста 🥺 ### 2/5 — Excellent game, adds destroy pleasure *2026-03-20, version 3.3.4* This is the best of the killer sodoku’s, I’ve been playing it a few times day, but the adds are driving me nuts, some take a minute, some get stuck and the app has to be restarted… only to get a new add. I’m off to try other apps instead Ps thanks for the reply, have an extra star, I still use it but not as much as I still hate the ads and it’s too expensive to buy ### 2/5 — Good brain game *2026-03-18, version 3.3.4* It’s a little harder than I thought. At least now even the easy one is hard. But I’ll catch on! ### 4/5 — Horrible ads *2026-03-12, version 3.3.4* After each game, ads for other hames come up without a way to exit. Every click goes to the get app screen. Can’t get out of the ads, and after 1 game and 5 minutes of ads I give up. The game is excellent but not worth the ad frustration. ### 2/5 — Viel zu wenig Möglichkeiten *2026-02-20* Spiele wiederholen sich ständig, langweilig **Developer response:** Es tut uns leid, dass sich die Spiele für Sie zu oft wiederholen und dadurch langweilig wirken. Wir haben Ihr Feedback an das Team weitergegeben, damit es die Inhalte überprüft und mehr Abwechslung in zukünftigen Updates in Betracht zieht. ### 3/5 — Di *2026-02-16, version 3.3.2* Ads constantly freeze game…all stats are lost ### 1/5 — Latest version is a disaster *2026-02-01, version 3.3.0* Made totally unusable by a rogue advert which shows just a white screen with a tiny logo and then just locks up no matter how long you wait. ### 1/5 — Freezes *2026-01-29, version 3.0.2* Was enjoying this. Reached expert,killer 3 but now it’s hopeless as it keeps freezing on ad and you can’t get rid of it ## Most critical reviews (10 lowest-rated) ### 1/5 — Used to be Good *2026-08-23, version 3.6.2* Sorry to say but forced adds is NOT cool. Getting worse recently. Sad to leave but it is not enjoyable playing it anymore. ### 1/5 — Constant ad interruptions *2026-08-13, version 3.5.12* This game used to be fine. Now, they constantly interrupt play with a forced ad!! I MEAN every few minutes, if not every minute!! You then have to click out of it and wait for the game to load again!! I’m finding a new one. This one sucks!! ### 1/5 — Intrusive Ads *2026-08-12, version 3.5.12* Before you get stuck in a loop of “ads” which are just other games, it’s quite fun. But once they send you down that ad loop, there’s no escape. You play a different game and there’s no exit button. You close the app, and it just sends you back. ### 1/5 — Ads ads ads *2026-08-09, version 3.5.12* Too many ads and ridiculously layered, tiny, repetitive x ads. Ironically, many ads state the advertised game has no ads. Also, why is the pencil in different places? ### 1/5 — Voller Spam-Werbung *2026-07-03* Das Spiel selbst ist in Ordnung. Aber man wird ständig mit betrügerischer Werbung für irgendwelche Fake-Wunderprodukte belästigt, die man auch nicht ordentlich melden kann. In den Privacy-Einstellungen kann man zwar ausschalten, dass Anbieter mit „berechtigtem Interesse“ Daten abgreifen können, aber die Einstellung lässt sich nicht speichern. Unklar, ob das Absicht oder schlechte Programmierung ist, in jedem Fall ist das nicht in Ordnung. ### 1/5 — Used to be Good… *2026-04-12, version 3.4.0* … until it crashes and glitches mid game. Developer never response back since it first noted by user back in May. They don’t seem to have anwers for this issue (piling up money from that much adds? 🤷🏻‍♀️. Found a new Sudoku developed by nerbyte, less adds and not freezes up. Bye bye Killer Sudoku! ### 1/5 — Lost two years of hints *2026-04-07, version 3.4.0* Today I opened the app to play and noticed I lost nearly 1800 hints I had earned. Many of these earned by watching 30 second videos. All of my statistics were also gone. Now after years of playing my daily challenges are all “Easy” because it assumes I’m a new player. Your advertisers need to be aware customer will no longer need to watch 30 second commercials if points are taken from them. PLEASE PEOPLE DON’T WATCH THE 30 SECOND ADS FOR EXTRA POINTS. MAYBE ADVERTISERS WILL ABANDON THIS APP AND FORCE DEVELOPERS TO ADDRESS CUSTOMER COMPLAINTS. ### 1/5 — Bug *2026-04-03* Since the new update, the game suddenly shuts down mid play. So unfortunate. I loved playing this game daily, now it’s very frustrating. When I’m playing a killer level for a few minutes, the app just closes. When I start it again, the level I was on is either reset to the beginning or only a few seconds in and then it shuts down again after another minute or two of play. There are other killer sudoku apps, but this was by far the best in my opinion. A real shame about this new bug. It was a 5-star game until now. ### 1/5 — App Closes Mid-game; customer service chat does not work *2026-04-01, version 3.3.5* The app has recently started shutting down on me in the middle of games, not saving entries made. I’ve tried using their “Customer Service” chat- no response. Really good game, but I’ll stop using it, and patronizing their advertisers, unless it is fixed soon. ### 1/5 — Excellent game, adds destroy pleasure *2026-02-18, version 3.3.2* This is the best of the killer sodoku’s, I’ve been playing it a few times day, but the adds are driving me nuts, some take a minute, some get stuck and the app has to be restarted… only to get a new add. I’m off to try other apps instead ## Most praised reviews (10 highest-rated) ### 5/5 — Used to be Good *2026-08-27, version 3.6.2* UPDATE 8/26/26 Have been playing again since yesterday, and no more forced adds so far. Well done! Sorry to say but forced adds is NOT cool. Getting worse recently. Sad to leave but it is not enjoyable playing it anymore. ### 5/5 — Long time player of this app… will not allow to write review….It is great gam *2026-07-24, version 3.5.10* I am in! I love this version of this type of game. I think this app is trying to protect us from voracious, misleading adds based on their game not having adds. I agreed to watch adds to play. I did not agree to participate with adds ….much less those designed to make it difficult to hang up without having your device taken hostage. This requires leaving the game, turning off search engine or App Store, then return to game and try to turn the add off again, . I have had this happen up to 6x from Junes Journey and Amazon adds. NOT ON THIS SITE! THANK YOU!Thank you! ### 5/5 — Отлично, но… *2026-05-24* Приложение отличное! Уже несколько дет играю только в нем. Но после обновления в ежедневных заданиях появляется только легкий уровень сложности! Раньше у меня был уровень Киллер. Сейчас не интересно. Сделайте возможность выбора себе уровня в ежедневном задании или хотя бы из последнего выполненного! ### 5/5 — Best I’ve tried *2026-05-15, version 3.4.5* I’ve tried a few Killer Sudoku one and like this one the best. I liked the idea of the coloured one, but shaded squares looked like different colours. This one moves quickly with few ads and auto completion. ### 5/5 — Батл *2026-03-16* Когда в батле доходишь до 100 уровня, хорошо бы чтобы он снижался при проигрыше, все интереснее будет, а то и так короткий проход от 50, так и интерес пропадает. А вообще отличная игра ### 5/5 — This is a hard game. *2026-02-24, version 3.3.2* I have been play this game for a long time. I only play on the extremely hard level. It challenges me to do better. ### 5/5 — Love game *2026-02-08, version 3.3.0* This is my favorite game I play it every day ### 5/5 — Amazing *2025-12-28, version 2.49.0* Amazingly fun game! This is the only sudoku app I have and I play it multiple times a day. Only complaint I have is the same as others’: price is too high. Wish it was a one-time payment. ### 5/5 — キラーナンプレ *2025-12-06* ゲームが開けないからできません。 ### 5/5 — Interesante *2025-11-11, version 2.43.0* Requiere mucha atención --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
