Good Sudoku by Zach Gage

A very cool game

I forgot how awful this one is and regretfully downloaded again by accident.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.

I am an avid user of the app. Had it for a long time and have been pleased with the interface and overall feel f the game with the added bonus of learning new techniques. Recently, even on latest gen iPad Pro, app randomly freezes and closes. Sometimes current game is lost, sometimes not. Would not recommend that anyone purchase until the issue is resolved due to nuisance of starting over alone.

I think this app achieves its stated goal of being the ideal sudoku app, with thoughtful and pleasing design along with genuinely helpful tips and lessons. unfortunately, i only use this app sporadically because it crashes so often it doesn’t feel worth the frustration. it freezes any time you switch screens (whether looking at another app, swiping down to change your music or check a notification, etc.) and sometimes reloads the app or quits entirely. when it reloads or quits, it sometimes loses your progress in the game you were playing. it also sometimes freezes while just doing things within the app. it seems like maybe a bandwidth issue because the app uses sooo much storage, but i really hope the creators are able to fix this because it’s truly a wonderful app!!!

Best app ever. I love you.

By far my favorite one that I’ve tried. I love their system, and feel like I am challenged enough while still being able to understand where I got stuck when I ask for a hint. Cannot say enough good things about it!!!

Ads aren't excessive, game has a lot of good quality of life tools. Update: previously I wrote that the hint system was terrible but that was because I was removing candidates instead of crossing them out which I guess confuses the hint system. Now that I cross it out the hints are very good

Has some real solid sudoku tips and tools, but I have zero tolerance for apps that utilize full-screen ads, some scammy and misleading, that all require pressing a skip button three separate times, each with its own countdown timer.

I’ve been enjoying the app with its lovely design/UI. It’s clearly a labor of love and a lot of thought went into this. However, I wish there was an option for focus without accent notes, or a less intense highlight on the note in general. I found the improve techniques tutorials a bit difficult to understand due to the accent notes taking my focus away from the regular notes that would be important to completing it. The current color scheme is a bit high contrast and leaves me a bit overwhelmed. Doubly so when using focus with accent notes. I did just find the black/white text color option which was helpful, but it still feels a bit crowded. Still fun though and offers plenty of brain twisting challenges!

I like the game, but just came across a frustrating problem. I'd almost completed a board and one of the "houses" had 8/9 squares filled. The game gave me a big red message blocking the screen telling me the game had reached an unsolvable state, and prompted me to "click here." Clicking it undid ALL OF MY WORK to reset the board! It was not unsolvable, it was a 5. The one remaining empty square was a 5, because it is the only number in that house not used yet. I hadn't guessed any numbers. Everything was reached using autofill and marking the board up. No mistakes had been made, and the game undid everything. I'd like to avoid that happening again.
