The last few days, though, the daily puzzles don’t load. Why? My internet is fine, so it’s not that. Why won’t these puzzles load? ### 2/5 — Pencil marks *2021-12-29* If you leave the sudoku puzzle by returning to the home page or closing the app the pencil marks don’t seem to save very far back in time and you have to redo some of it when you resume the puzzle. It would be nice if there was a manual save function or an automatic in-built save function every 30-60 secs. ### 3/5 — Good app *2021-01-27* However I was at first elated when I saw the notepad thinking I could make strings and loops, underline some candidates, uncover patterns etc. But after returning to the puzzle all the notes are lost! Very disappointing! ### 3/5 — Pencil marks hard to read *2018-10-17* 17.10.2018: Bug: Während eines noch nicht beendeten Spiels versehentlich die Hometaste erwischt. Dann leider kein Resume verfügbar!-/ Das scheint dann zu passieren, wenn bereits neue Spiele verfügbar sind. Und bitte: step-by-step Solutions der Webseite mit den echten Zahlen!! 12.1.2015: hey, ich war noch nicht fertig! Nach 1 Stunde Arbeit an einem diabolischen Spiel Reset auf Hauptmenü beim Aktivieren aus dem Hintergrund. Inklusive Markierungen für eine lange Forced Chain. Mist! 18.12. 2014: Auch nach Umstieg auf iPhone 6 sind die Kandidatenahlen kaum lesbar! Auch ist der Unterschied zwischen vorgegebenen und eingegebenen Ziffern nicht zu erkennen. Beste Algorithmen und Auswahl an Spielvarianten aber zu anstrengend. ---------------- Heute mal wieder gespielt. Riesenbug (oder soll das etwa ein Feature sein?): die Varianten passen nicht zu den offiziellen Sudokus auf der Webseite. D.h., keine Möglichkeit, die step-by-step Solution in schwierigen Situationen zu Rate zu ziehen und zu lernen! Die internen Tips sind ja höchstens einmal zu gebrauchen. ---------- I have been using this app since 2009 and updated to the latest version today. While I like the overall design I simply can't use it anymore. I have extreme difficulties to read the marks because of the dim font used. Apparently there's no way change this font. Furthermore, the solved numbers entered are hard to discriminate against the start numbers. Will go back to the old version and its task switching bug that often discards your current state when switching back under ios7. ### 3/5 — What happened??? *2017-07-26, version 1.90.000* I've been playing this game since the days of the color Palms. I made sure to buy it when I switched to an iPhone. Now Everything got so small. Difficult to play. My fingers are to big and I'll have to switch to a stylus. :-( ### 2/5 — The ads are loud, long and annoying *2016-01-24* The sudoku games are great. Between each game, they play a very loud 30 second commercial that you can rarely skip. They don't offer an option to pay to skip the ads. You are stuck being bombarded with noise about another app that I have no interest in ### 1/5 — Adds on Sudoku *2015-12-05, version 1.82.2* I purchased the sudoku version with no adds a long while back. I enjoy the games daily. The past three days I have gotten intrusive video adds I am forced to look through when I go from Fiendish to Diabolical! I have never seen this before! There isn't even an option to skip it! I tried to send a note to Sudoku about this issue, but there seems to be no way to actually contact them. Sudoku wants you to wade through FAQs without a clear option to send an email concerning a problem. Not happy 😖! How can I fix this?! ### 5/5 — The Best! *2015-03-07* This is the best Sudoku game going! 6 levels to choose from each day, and other random sudoku game to play if you've already done what you want with the game of the day. Love this! ### 3/5 — Wiped out game *2015-02-07, version 1.80.6* I enjoy playing sudoku daily. I have enjoyed this app for several years. However, one of the recent updates frustrates me. I don't always complete a game in one sitting and like to come back to it a bit later. Before the update I could come back to the game I was playing with no problem. Now, after the update, when I return to the game it refreshes and wipes out the game I was playing. Please fix this! ### 5/5 — A daily habit. *2014-12-23, version 1.80.6* Great way to spend a few minutes everyday! Works great. Love daily puzzles. Nice to compare times to other players (except the dummies who think they are fooling someone by posting times under 2 minutes). ## Most critical reviews (10 lowest-rated) ### 1/5 — Poor ipgrade *2025-11-09* This game was add free, not any more. I use to enjoy seeing all of the opponents scores now I just see the top and the ones around my score. Now if you fill the last number you can’t remove the same little numbers, so you have to remove them all before placing the last number. I am deleting this game and searching for a better version. ### 1/5 — Multiple solutions found *2024-10-01* First tricky puzzle I did proved to have multiple solutions. I would not suggest this app to any true sudoku fan. ### 1/5 — Where is my saved puzzle? Not saved anymore? *2024-07-10* Just updated the app. Appreciate the bigger grid but navigation within the app has changed and it’s it’s not user-friendly at all anymore. Can’t find a Support link. Can’t find anyplace in app to comment on the update, which is where you said to go with questions. BIG QUESTION: Where is my saved puzzle? I got back into the app today and my almost finished puzzle that I’d entered myself is not there anymore?! WTH?! I used to recommend the app to friends, but can’t do that if I can’t get back in to finish my puzzles! ### 1/5 — Latest upgrade removed ad-free *2024-04-30* I had ad-free and that disappeared with latest update without any explanation, nor can I restore my status. Not impressed. Had been best version of this game but no more. ### 1/5 — Purchased but still get ads *2023-12-30* After buying the app I’m still limited to a couple games before I have to watch an ad. Why buy it if it still has ads? ### 1/5 — Update ruined it for me *2023-06-19* I played this daily for years, but your updated version has ruined that. I guess I need to find another one ### 1/5 — AWFUL UPDATE *2023-03-12* Cannot see the numbers properly because of the new graphics. ### 1/5 — Well this was once fun. *2023-02-27* Had this for years. It was clearly on autopilot. After years with no substantive changes an update happens, gone was the fairly clean graphics, but all of a sudden, it requires a subscription, or only allows a few games/day (I had paid for ad free, a one time charge, years back) Can I downgrade to the old version? ### 1/5 — Latest update is annoying *2018-05-04* You have to log in with your Apple ID every day if you have paid for no ads. The messaging system doesn’t work. Very frustrating ### 1/5 — Latest version fails to load! *2017-08-26, version 1.90.001* I love this app, but the latest revision crashes when opened on my iPad Air 2 with latest iOS. ## Most praised reviews (10 highest-rated) ### 5/5 — Play it everyday *2025-07-12* Simple straightforward game, love it. ### 5/5 — Fun and challenging *2024-05-18* I play this every morning when I get up. Gets my brain going for the day. ### 5/5 — Awesome *2024-04-17* It was a great app ### 5/5 — The best ! *2023-12-17* Plus de 10 ans que je l'utilise et ce soir Astraware m'offre gracieusement la nouvelle version ! Merci ### 5/5 — Best Implementation *2023-03-08* I have enjoyed this version from Astraware for over 5 years. While getting the game for someone else I noticed there were only 2 reviews and they were both bad, so I’m adding mine. The interface is clean. Row and column highlighting adds to it. There are options for pencil marks (selecting possible numbers). I like the option to automatically remove pencil marks of the same number in the same row, column or square when I select input the correct number. I’ve purchased the game so I don’t get any adds, and I’ve never had any problems with losing my purchase and getting adds again. I haven’t tried all the available implementations of sudoku (there’s a gizillion of them), but I tried more than a few before I came across this one and that’s when my search ended. ### 5/5 — The best has got even better! *2023-03-07* Just when I thought there couldn’t be a better Sudoku app than this one, it gets even better, with an improved, clearer interface and all-round more logical and straightforward layout and settings. This update is more than just cosmetic, and has taken the app streets ahead of the competition. The puzzles themselves are excellent, a good range of difficulty, with graduated hints available that can become more detailed if the first hints aren’t enough. A great, appealing way to learn and improve Sudoku skills. I’ve tried a number of Sudoku apps and this one is outstandingly the best. Truly excellent. ### 5/5 — best Sudoku out there *2023-02-25* I am playing Sudoku of The Day since the old Palm PDA many years ago. It has always been highly challenging, the GUI is intuitive to use, and the new version is even better. ### 5/5 — Great *2019-01-30* Allows you to solve the puzzle yourself. Gives helpful hints without doing the work for you. Excellent!! ### 5/5 — The way Sudoku should be. *2015-12-10* It's well worth paying to remove the banner ads, because this is a wonderful sudoku app. It has a very simple and elegant interface, beautiful graphics, a choice of fonts, and a Daily Puzzle feature that lets you rate your best time against other players. If you enjoy Sudoku, you can't go past this app. ### 5/5 — Best Sudoku game period. *2015-05-24, version 1.82.0* I love this app! It's clean, lots of help to solve puzzles and it's just fun! This is definitely the best Sudoku app period. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
