Good Sudoku by Zach Gage Wiki

I’ve been using my iPhone for 4-5 hours/day for the last 10+ years, and every 3-4 years an app comes along that just changes everything for you. Apps like google maps, or dark sky. Brilliant execution that change how you experience your iPhone and bring joy to your life. Good Sudoku is one of those apps. It changes the process of solving sudoku puzzles from one of relentless scanning and book keeping to one of *really* engaging your higher thought processes and learning advanced techniques. it also, in just 2-3 days, has taught me more about how to solve sudoku puzzles, seamlessly, than i had learned in the previous 20+ years as a casual solver. The interaction is a delight, and i genuinely look forward to each new chance to play with it. These are one of the apps that I would pay money to rate 6 stars, and it’s the sort of app you should have no problem paying $20-$30 for. It’s good enough that i would recommend someone who loves sudoku to buy an iPod touch *just* to play this game. Game changer (literally) - thanks so much to the developer and designer who clearly put their heart and soul into it - you have made my life better.

I want to start by saying I never write reviews for apps. The other day I downloaded Good Sudoku more out of curiosity then anything else and instantly fell in love with it. It works so well, with some great time saving features that remove some of the mundane parts of sudoku. I also find it really useful that the app teaches you new techniques of how to solve sudokus when you ask for hints rather than just showing the number. This is certainly the best sudoku app I have ever seen and probably one of the best apps on iPhone now as well. I have noticed a few small things while playing this game in the past few days though. One, the notes feature sometimes unclicks while I am trying to remove numbers from boxes, making me erroneously input numbers I know to be wrong into those boxes. Additionally, it would be great if there was a feature that allows one to hold onto a box to open up the note pad feature, similar to the way that one can drag over multiple boxes to open that feature. Overall though, Good Sudoku is an excellent app.

This is the most Awesome Sudoku app ever! I am a casual Sudoku player, started with pencil/paper, then some other Sudoku apps. What I like about Good Sudoku app is it takes away a lot of tedious note taking. At first, I was having a lot of fun finishing Impossible level puzzles fast by using UNDO to go back to fork points. I noticed that some achievements popped up saying I achieved some Sudoku technique. That got me very curious because I didn’t even know so many Sudoku techniques existed. Good Sudoku app actually has a very detailed learning section with a lot of references. I’m learning the proper techniques, and can even solve Impossible puzzles now without using the UNDO button anymore. I love this app! Thanks for teaching me Good Sudoku. Well worth the price. I only wish there’s a way to stay in Highlight mode and Crossout mode without having to constantly click into it. In Eternal mode, I sometimes lose hearts because I though I was still in Highlight/Crossout mode. Also, would be great to have a shortcut to the learning section without exiting the current game.

This is a great sudoku app, and I’ve played it a ton over the last month. I highly recommend it to anyone who likes sudoku, especially if you’d like to improve in your techniques (or if you didn’t even know there ARE techniques). The only reason I didn’t give this a 5 is because of a recent bug that disrupts the way I play. I love the “Eternal” mode, because I can roll right from one puzzle to the next, and there’s a slight incentive not to use hints. But starting a few days ago, it’s not uncommon to finish a puzzle and see “Sudoku Complete!” without any of the following stats and the button to continue. The app becomes unresponsive, and I have to close it to continue playing. The Eternal run didn’t save the most recent progress, so I’m back at the last puzzle I solved, and the process repeats itself. Hopefully this could be fixed soon; I love Eternal mode, and this app deserves five stars!

There’s no better Sudoku app on the App Store — of that I’m convinced. After months of play, however, I have to admit that I’m frustrated with its minor flaws and daily annoyances. First, it’s great that there’s a leaderboard for the daily sudoku, but I have not and will not ever place on it, and the effect is that the app mildly negs me every single day. I didn’t place in the global top 250! I get it! I’m just a guy doing a sudoku. Next, I love the idea of a daily challenge, but wish it was approached more like the solitaire app I play where I can go back and fill in a missed day. I had a huge sudoku streak going but had a bad reaction to my COVID vaccine and missed a day and broke my streak. Now my motivation is tanked. What it boils down to for me is that sudoku is extremely relaxing and improving my game is extremely satisfying, but I’m gradually starting to resent the low-level anxiety this app is producing. In the big scheme of things it’s super minor! But it’s something that has become a part of my day so worth speaking up. Thanks for an otherwise insanely fantastic app that has genuinely made me a better player.

I’ve been playing sudoku on and off for years, and I still learned some surprising tips and tricks from this app! This app doesn’t seem to necessarily reinvent the game, but it does make sudoku feel fresh again. Part of the fun is the easy to use automated features. And with a one time in-app purchase, it‘s a deal! There’s two very minor things I would consider changing. One is I think in the settings it defaulted to left-handed mode (unless I bumped the setting by accident early on). Might be best to either default to right-handed or ask during the first app launch. The second thing is a bit nit-picky, but I’m the main screen there’s a sliver of white across the top which I’d get rid of.

I’ve tried a moderate number of Sudoku apps, and this is one of the best. The interface has some good time-savers. I especially like the ability to select multiple squares and make notes on all of them at once. The worst thing for me is the legibility of notes. I’m using an iPad Pro 12.9, so the text is as big as it’s going to be, and it’s still hard to read in some circumstances. The typeface is light (as in thin strokes) and it also seems to be gray, not black. When it’s on a white background, it’s not bad, but in focus mode, you get gray on orange, which is terrible. I can read the numbers mainly by position in that case. I also run into this bug fairly often: when I tap the hint button, the hint shows up, but if I tap the book icon for more details, nothing happens. To be sure, it works most of the time, but fails often enough to be aggravating.

Best sudoku app I’ve found, but drains my phone battery quickly (even after updates) and I repeatedly run into puzzles with non-unique solutions (e.g. where two pairs of numbers can be swapped because they line up in the same rows and columns). This is especially frustrating as the app teaches strategies that explicitly rely on eliminating possibilities that would lead to non-unique solutions. This means that for these specific puzzles, doing what it teaches you will result in being penalized and potentially losing in Arcade or Eternal mode. It also results in situations where you’ve made no mistakes but the puzzle gets into an “unsolvable” (according to its own hint function) puzzle that I have to resort to trial-and-error to solve. Despite these frustrations, it is a fun and well-designed sudoku app and I play it a lot!

I never thought I would get into playing sudoku, I always thought it was for old people but this game it one of my favorites! I really wanted to give it 5 stars but there are bugs that need to be fixed. Sometimes words are cut off from the screen. And the AI in create mode is pretty broken, when it tells me that my board is not solvable, it asks me if I want to restore it, when I click yes the it just deletes my entire board. Also when in create mode, when you click on a cell it shows you the possible all possible answers for that cell, but sometimes the choices it gives are wrong( having two 9s in the same column ) That is all the bugs that I experienced, and I hope they will be fixed because I really love this game!

I first played Sudoku on paper back in ~2005 and enjoyed it somewhat. I pretty quickly ran out of patience to learn advanced techniques and set Sudoku aside. Fast forward to 2020 and I’ve been hearing good things about Good Sudoku. I tried it out and the UI is very pretty and fun to use. I have learned some techniques that are way further than I would have ever gotten to on my own. I also really enjoy the daily puzzles that get harder à la the New York Times Crossword. The main problem I see is that my progress is not synced between my iPhone and my iPad. I want to build up a streak of daily puzzles. But since I prefer to use my larger iPad screen, I’m finding that I’m not playing the game during a lot of moments where it otherwise would have been perfect, if only I had my iPad handy.

Good sudoku is really very good! The only features I feel could improve are the processing of daily contests. It appears that people are using the raw API to achieve high scores rather than playing by hand. Even were it not the case: I’m a player that can complete basic and even expert puzzles in a little over 2 minutes, up to 5. I have a pro puzzle in under 9 and several under 12: all without hints. and I don’t get any recognition. I know I may not be in the top 250, but you’d be hard pressed to find someone within a mile of here who performs better. I feel that if I don’t merit recognition, too much of their audience also must fail to see any reward in their daily challenges gamification.

When it worked, Good Sudoku lived up to its name. It was one of the nicest-looking, most feature-packed Sudoku apps I’ve used. It was a little heavy on the ads, which I was normally okay with. Sometimes if I was in an area with poor connectivity (i.e. the metro) it would fail to serve an ad when I started a puzzle, then try to serve me an ad in the middle of a puzzle which would reset my progress. That issue was frustrating but bearable. Since a recent update, though, the app crashes near constantly (I have an iPhone X). It crashes 50% of the time when I start a puzzle up and it tries to load an ad. It crashes like 80% of the time when I finish a puzzle. Sometimes it crashes for no apparent reason. I’ve tried closing all other background apps, restarting my iPhone, and redownloading the game. It has, if anything, gotten worse. It was a stellar Sudoku app but until they improve stability it’s pretty much unplayable for me.

I have an iPad eight and my iOS is updated. This game is mostly fun but after a while the glitches really get to you. Sometimes if you push the red pencil to delete options it doesn’t work. Sometimes you can push square after square and it will still be red and sometimes it just goes back to normal. Then you push theNumber you mean to delete and the system thinks you are trying to enter that has the answer and bleeps the error noise. There seems to be no rhyme and reason to the scoring. As you play there is a score recorded in the upper right hand corner. But it seems to have nothing to do with the score that happens at the end. They never match up and don’t seem related at all. I really wish that function keys worked correctly all the time. They just don’t and then it becomes frustrating. I’m taking this off my device for now and maybe I’ll try again one day. They have some good ideas in teaching you how to play sudoku and I do like that it fills in all of your options so you can figure it out.

My prior review seems to have vanished for some reason. This is a good app but the bugs are driving me bonkers. The AI that attempts to guess when you’re done eliminating candidates has been extremely flawed from day one and has literally always been more of an annoyance than a help. There is an option to turn it off in settings but the app ignores it. The developers response to my previous review about the setting being ignored? “If you don’t like that feature you can turn it off.” GEE THAT WOULD BE SWELL, MAYBE YOUR APP CAN LISTEN TO ITS OWN SETTINGS. This current release not only STILL doesn’t fix this, it’s now worse. Now not only does the AI still randomly stop selecting a cell/group of cells when attempting to eliminate multiple candidates, it now also randomly switched modes to entering numbers. So in the middle of eliminating candidates it now, without warning, enters the number I’m trying to eliminate. This has caused the app to register multiple “errors” in arcade mode and is really making me angry. Seriously, no one asked for this candidate AI “feature” and it has never worked. It is so buggy that even turning it off doesn’t work. This one thing is completely ruining the experience of an otherwise excellent app and I seriously cannot understand why getting the app to listen when I turn it off in its own settings is apparently so hard for the dev to accomplish.
