In comparison, I find the prominence of the grid lines to be distracting in the iOS version. Please consider changing the look. ### 4/5 — Sudoku💎Rocks💎‼️ *2021-03-31* The ONLY thing that could improve this app is an overlay screen to take notes on. Thanks for a superb game! ### 2/5 — Not enough data *2020-11-23* Keep getting that line, and for some reason the puzzles don’t finalize as I complete them. **Developer response:** Thank you for letting us know. We just released a new version. Please update the app. ### 4/5 — Request Feature *2020-11-16* I have been using this for 4 years now. I miss a feature of coloring notes so that I can find easily matching pairs, sword fish etc in notes. Can you please enable? ### 4/5 — Good but difficulty levels are shifting *2020-09-13* I’ve been playing this version for years and I noticed that every now and then the difficulty levels shift dramatically. It happened again about two weeks ago. I used to be able to solve extreme level in average of 8 minutes (daily). In the last 2 weeks that level has become unplayable. ### 4/5 — Good but not hard enough *2020-02-03* Interface is very user friendly- 5 stars Extreme puzzles aren’t so extreme- most of them can be solved using normal logic. Expecting harder ones that can be solved only using the advanced techniques. ### 3/5 — Thought this was ad free *2018-10-15* I thought I had the ad free version until ads for another game starting popping up after a game. The X to close it does not work. I guess I'll delete this game and purchase another. Maybe it will honor ad free **Developer response:** This app is ad-free. However, it's icon looks exactly like the icon for a free version. You probably just ran the free version instead of the paid one, which is why you saw ads. You can simply delete the free version. ### 2/5 — Did not replace the free version, no way to import scores *2018-05-28* I just downloaded the paid version because I was sick of ads playing sound in the free version even when my phone was on silent. What irritates me is now I have two Sudoku apps on my phone. Why didn’t the paid version replace the free version already on my phone? I also have no way of importing my scores from the free version into the paid version. This seems like a huge oversight by the developer. **Developer response:** They are two different apps. Installing one cannot uninstall the other, but since the paid version does not rely on the free one to function you can uninstall the free one. We are working on switching to upgrading via in-app-purchase, thus you won't be needing to get a new app. ### 4/5 — Not too shabby *2017-10-26, version 10.2.4* I’ve been playing this for a while but finally decided it was time to pay for it as it has kept me occupied on the train a lot. It’s a shame there’s no way yet of transferring your scores from the free version. Or that until I upload scores from the premium one whether my account information is correct. Maybe this app is no longer being developed as I noticed the free version stopped having in-line ads but thanks for all the fun. ### 3/5 — Not Bad *2017-09-20* Format easy on the eyes and functionality good. Hard too easy and extreme too difficult. Need additional level between the two. ### 5/5 — Beginning or Challenging *2017-05-22* Go into "Settings" and set game to 'on' to notify you of incorrect entries....if you are a beginner. Game works perfectly. ### 5/5 — Great app *2017-05-14* Love this game, like the competition ### 5/5 — Sudoku premium *2017-01-25* I like the new board and selecting choice. ### 5/5 — Great update *2017-01-04* I love the update and it's new clean look. Have enjoyed online sudoku for more than 12 years and relish the challenge of your extreme puzzles ## Most critical reviews (10 lowest-rated) ### 1/5 — Ads on premium version *2022-12-28* I bought the premium version NOT to see ADS. Suddenly there are ads at the top of the screen. Breach of contract!! ### 1/5 — Nicht wirklich überzeugend *2020-11-27* Seit dem Update auf Version 11 läuft die App recht instabil. Bei fertig gelöstem Puzzle bleibt die Anzeige häufig stehen, ohne auf die Auswertung umzuschalten. Schwerer wiegt für mich aber auch weiterhin, dass der größte Teil der präsentierten Sudokus leider nicht wirklich interessant genug sind. Die hier favorisierten sehr symmetrischen Sudokus entsprechen japanischem Geschmack, sind aber doch recht langweilig. Auch auf der schwersten Stufe braucht die Lösung oft nur knapp 2 Minuten; es könnte gern anspruchsvoller sein. Großer Pluspunkt der App allerdings bleibt nach wie vor das vorbildlich durchdachte, ergonomische Layout. Dafür 3 Sterne. Nachtrag: Nachdem die App sich aufgehängt hatte und neu aus dem Store geladen werden musste, ist nun der gesamte Verlauf (persönl. Bestzeiten) verschwunden. Das geht leider garnicht und führt zur Abwertung. Nachtrag 2: Inzwischen wurde mit Version 11.0.5 das Problem behoben, dass gelöste Puzzle nicht ausgewertet wurden. Meine persönlichen Bestzeiten sind wegen schlechter Programmierung der App aber nun einmal verloren und bleiben es. **Developer response:** Thank you for letting us know. We just released a new version. Please update the app. ### 1/5 — Not right. *2020-11-26* Second table m puzzle will not solv due to conflicting numbers **Developer response:** Hello. Thank you for writing. The only way to get "conflicting numbers" in the puzzle is by you putting them there. The initial condition is never wrong. If you wish for the app to prevent you from entering erroneous values please check the "Flag incorrect values" setting. Also, if you want to check your progress at any point, the Validate option under Menu will check your solution and highlight any errors you may have. ### 1/5 — No Custom Mode on iPhone! *2019-12-26, version 10.2.4* I found a special Sudoku online that I wanted to play in digital format and my friend has this app on Android and it has a Custom mode where you can input your own puzzles. This is absent from the iPhone version. Waste of money. ### 1/5 — Disappointing. *2017-02-04* I bought this app because I have been using the free version for over a year. I was disappointed to find that there literally is no difference between the two versions. Save your $2 and get the free version and stick to it. ### 1/5 — Don't like the new look *2017-01-02* Please bring back the previous version, this new version is really frustrating, all the added steps to take just to "Validate" the game etc, are extremely annoying. Besides, the new look isn't aesthetically pleasing at all. It used to be my most favourite game on both my iPhone & iPad, I used to play a few games a day, but not anymore, I also stopped altogether, playing it on my phone. I also found that in "Settings/About", the blue links over a black background, are impossible to read. Would you kindly fix this, I have played your sudoku games for about 10yrs. Thanking you S ### 1/5 — Was The Best!! *2016-10-25, version 9.0.2* I love this game but now locks up, freezes and slows down my Apple device. Please we need an update!! I would love to give you a five stare rating again but need the app fixed first. ### 1/5 — frech *2016-03-27* Nötigt zum Bewerten. ### 1/5 — eigentlich Super *2015-01-22* nur derzeit geht sofort der AppStore auf und das Spiel lässt sich nicht starten. Ich kann momentan daher nur ein Stern vergeben. Wenn es wieder geht, dann wieder mehr. ### 1/5 — Another bug? *2013-03-08, version 9.0.2* I have been enjoying the free game for ages following the latest IOS download. The game quits every time I enter my score. So I upload the upgraded game only to find the same happens. Now I cannot even finish a game as it quits the program when it gets about half way through. Has this been released too soon? The purchased version is better but still prone to quitting without warning. The pop up screen between games is getting on my nerves and if it continues much longer I will erase the whole game. I did not pay to watch pop up advertising. ## Most praised reviews (10 highest-rated) ### 5/5 — Best sudoku *2024-12-09* I have played the many other sudoku apps but this is by far the best. ### 5/5 — great sudoku app *2022-10-17* It does everything you’d want a Sadako app to do. ### 5/5 — Good *2021-01-22* No complaints ### 5/5 — Finally paid (again?), but they deserve it! *2020-04-04* I’ve played this version for years and moved it - or downloaded again - with every new phone or tablet. I’ve paid before, I’m pretty sure, but under a different email, so... But, I’m doing so again, not because the ads are annoying (honestly, I hardly notice them), but because it’s so inexpensive and more than worth the nominal fee to support the developers. ### 5/5 — Clean interface. Worth it to avoid ads *2019-08-31* I used to make do with the free version, but recently ads have been showing up with audio tracks. Given that I have been using this product for years, I too have decided that the developers deserve to be paid and I get peace and quiet. ### 5/5 — Love!! *2018-10-31* I’ve tried many different sudoku apps and this has always been my favorite! I finally bought the app, not because I was sick of ads (there are not many) but because after years of deleting every other sudoku app but this one, they deserve the couple dollars they ask for. ‘Digit first’ is what it’s all about. As well as the simple, pretty design that makes the game easy to play and calming. Love! ### 5/5 — Great App with easy playing style and functionality *2018-05-29* The highlighting of lines from the active number makes it easy to scan around both directions. With the selected number ‘blueing’ makes it a simple task to check your game and with each number reflecting your status I rate this over paper Sudoku every time. Great to be able to leave a game and come back at any time to continue. Hard to misplace like with books, as well. ### 5/5 — Great Puzzle Game *2018-05-03* Well worth the money for the ad-free version. Has all the sudoku features that I need. ### 5/5 — Great Sudoku app *2017-09-19, version 10.2.4* Very easy to configure and play. Levels are realistic. ### 5/5 — Alan loves Sudoku. *2017-07-23* From my using approximately 15 different apps and handhelds, this is the best by far. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
