Too pricy

I would give it five stars but the pro mode is too expensive for just getting unlimited games. Everything else in pro mode is kind of pointless. If it was $0.99 I would recommend it and change my review.

Best Sudoku App… almost perfect

I love this app, it is certainly the best app i’ve ever found. Aside from the simple to navigate UI, minimalism, and the rick roll banner ad (I totally fell for it)- the statistics is something that any sudoku nerd needs. Seriously, I’ve deleted my other sudoku apps. My only complaint is how the notes work. I’d like it to be more traditional, like put them in the typical order and spaces. I find the notes function hard to use since it’s a lot of visual information that’s hard to quickly read. With me at least, I don’t rely on reading the numbers themselves, but rather reading the location I expect them to be in, and find patterns/answers from there. Also, you can’t put more than 4 notes in it, which makes it kind of useless for me. As I start playing harder levels, I’d like it to use the notes, but don’t with this app. If others like the way it is now, perhaps putting in a way to toggle which notes version they prefer. I have never left a written review for an app, but I really love this one, so I’m invested in making it perfect and if the devs changed this one thing, I’d be over the moon. Either way, this is still going to be the only sudoku app I’ll use.

Great features & lives up to name Not Evil

I really love this app - I’ve been using the free version for a few months now. The one puzzle per day didn’t bother me so much as I’m not an avid sudoku player, I only do one puzzle before bed usually. No ads is STELLAR (wish/hope more phone games are like this). I also really appreciate the different levels of difficulty and various customizable features like turning on/off the number highlights. I never felt particularly good at sudoku when I was young (I hadn’t picked up sudoku in a decade!!) but the way this app is structured has helped me learn new strategies & increase the challenge based on what settings I use. Less important but this app works in dark mode settings which just adds to my contentment. I just paid the one time $5 for the upgraded version (to support the developer) and am curious to try the features that unlocks too.

The best at not being evil

I’ve tried many sudoku apps, and this is the best one I’ve found! It has a simple-to-navigate display, helpful game features, and just a cool design in general. There are no ads and no selling of data, which is a huge plus! Of course, this means to unlock all the features of the game and unlimited games daily you will need to make a one-time purchase. I personally feel that one game per day is enough to practice and to have fun with, just like Wordle or any other daily habit, but unlimited games is definitely a huge plus for other free sudoku apps. It’s up to you whether to make the purchase or not, but I think it’s worth it due to it’s features, design style, and simplicity. Overall, good game and worth the time and the optional purchase. If you’re looking for a simple and fun sudoku app, you’ve come to the right place!

Least Evil Sudoku Ever

It takes a bit of customization to get the app tuned to your preferences. I personally recommend turning on Speed Demon (beta), >4 notes (forgetting the actual setting name) and fixed note positions - it is worth noting some of these are under settings > advanced. The number placement can be a little janky at times (speed demon helps a ton) but it’s perfectly functional. Honestly I’m just glad to have an app that isn’t bogged down by ads. The default experience is one game a day which is fair but you can pay 5 USD which permanently gives you unlimited games and more cosmetic tweaks - unlimited games alone makes it worth imo, the rest is icing. Dev, thank you for making this; I hope more devs follow in your footsteps of less evil monetization.

Clunky controls, clunky interface, and…

… and you can only play one sudoku a day. Unless you pay 5 dollars. The controls on this are really clunky. You tap a square and then input your number. Most other sudoku apps have a system where you tap a number then the squares you want to fill- it’s much, much easier that way. It’s really hard to keep track of what square you have selected. The interface in general is really clunky. If you want to play a Hard sudoku you have to go into settings and switch to “Hard” … and wait for the next day. Notes/pencil marks are really clunky too. You can only have up to 4 pencil marks per square, and if you have more than 4 in a square then it simply hides the extra numbers. It becomes a real hassle if you didn’t realize that. Putting down numbers does not remove pencil marks either. So you have to go through, tap on each individual square, double check you’re on Notes mode, and then remove pencil marks. Could not control any worse than that. It was really insulting to find out that you could only play one a day. It was even more insulting when it asked me to pay 5 dollars to get the worst controlling sudoku app I’ve ever used. If this is what being “not evil” gets you then consider me a villain.

Overall, great app.

I did come into this app knowing I'd purchase the upgrade if it worked well, as I'd rather support developers with transparent pricing/no tracking or ads. You might have a different experience if you're looking for a "truly free" app, as you are limited to one puzzle a day. I was really impressed! I love that it's possible to turn off assists and solve it like an old paper sudoku. The haptic feedback is a nice touch. I love that you can set your own daily puzzle notification time, since my sleep schedule is cursed. I'm happy with the difficulty. I've played a lot of sudoku where "medium" was a cakewalk, but these have been consistently challenging. It would be nice if I could track the number of mistakes I've made in puzzles over time. I'd also love to see a "warm" mode similar to other sudoku apps, or more variety in colors I can pick. I look forward to seeing any updates or new apps from this developer in the future!

Good but there’s an annoying bug

I’ve enjoyed playing Sudoku on this app. It has some nice features like auto removing notes when you fill in a number. The look of the app is very pleasing as well. The app limits you to one game per day unless you pay a one time fee to unlock the full version. This is fine and makes sense since the app doesn’t run any ads and has to make its money somehow. The problem I have is after I purchased the full version I’m unable to “Start over” or select “New Game”. The only way for me to get a new puzzle is to complete my current one. Which can be a problem when I get stuck on a particularly hard one.

Best Sudoku App, Period.

I don't even know where to start. Between all the handy features, the sleek interface, the privacy-forward development, lack of bugs or glitches, offline capability and cute icons (waffles stole my heart) I'm not sure what I love most. I don't have high expectations for simple apps like this but Not Evil takes the crown. I start every day by playing one round to help get my brain going. This perfect app is one of my keys to having a great day. I was not compensated for this review & I don't know the dev, I just LOVE this app. Thank you!!!

Astonishingly soooo Ah-haaauuuugghhh

Randomly (today) in my study hall I was incredibly bored and decided to look through my recommended games, saw this and sighed “why not… they all have ads so whatever”, but I read through the images on the store and saw that there are no ads😳 “no way”, way. Played my first sudoku without ANY sort of ads, was down that I only got to play one a day so I bought premium. Current experience so far: Very Much Worth the moola-moola, green cheese, fat stacks, bread, dead presidents and so on 😁🎉

I wish all apps were like this!

I’ve been looking for a good time-killer / brainless app that doesn’t have an insane amount of adds, is impossible to play without becoming a whale, or tracks your data. Which I would THINK is not that much to ask for, but APPARENTLY it is. This app is a lifesaver and I would love to see more like it from the same developer (eg: not evil minesweeper, not evil solitaire, maybe even a few originals!) the $4 is well worth supporting a developer that doesn’t use insanely scummy practices

Good enough game

It’s sodoku. It’s good sodoku. That’s not what I’m complaining about. But calling it “Not evil” sodoku and the main point being no ads and acting like you’re better than the ones without ads is a step too far when you’re putting the puzzles behind a paywall. 10 hours is just too long in between sodoku puzzles, and I’d much rather just watch a 15 second ad instead. You could still get people to buy the pro version just for the stats, too. It’s not bad, but honestly I feel that acting like it’s better than any other free sodoku game that has ads is a lie.

Worse than other apps

This app claims to be “Not evil,” but only allows you to play 1 game a day unless you pay five dollars for unlimited. There’re also other features locked behind a paywall such as charts. Other apps might not have charts, and might have lots of ads; but they still let you play as much as you want. The amount to remove those ads is also as much as this app’s paywall is. This app tries to make itself out to be not evil while falling prey to the same traps that other apps make. If you’re going to paywall your app, just add ads so people can play as much as they want. Although it’d be basically a copy of other apps in that way.

It lives up to the name

If you want to play 1 sudoku a day on your phone and not have ads or other garbage this is the only sudoku app to use. I checked out others but they are either un-useable due to ads or they collect all of your data. The creator has been actively updating it and if you want unlimited sudoku instead of daily you can upgrade to a pro version.

Amazing Simple Sudoku Game

I really love this game. Only problem I have is that I just bought the plus version not realizing that buying the pro is much better, but since i’ve already bought the plus I have to pay the full price of the pro. I feel like there should be a cheaper price to upgrade from plus to pro. Other than that, it’s a perfect app!

2 years ago, june880022

All around fantastic!

I love sudoku but I am very picky about sudoku apps. This one is great! The design is simple and easy to navigate. There are absolutely no ads which is always a plus. Upgrading to unlimited puzzles and other features is very inexpensive. I also really like the way the settings are set up. Fully recommend this if your looking for a good sudoku app with no gimmicks.

1 year ago, BasilPestoSauce

No ads! Instead it’s much worse.

Somehow, the Devs of this app didn’t stop to think about the fact that maybe, just maybe, the only thing more annoying than ads, is paywalling the app. You can play one, Just one, game every three hours. Which in itself is pretty ridiculous. Not only that, it locks the entirety of the rest of the app behind a subscription paywall. Just because an ad is for your own company, doesn’t make it “ad free.” This app is a mediocre sudoku app with a steep price that doesn’t match the benefit. But hey, at least there’s not “technically” ads.

1 year ago, Dfjjfgozdaughknkb

Just as evil as sudoku games with ads

Claims to be an ad free and "not evil" version of all the other sudoku games out there, but if you want to play more than one game a day, you have to buy premium. Frankly this is worse than games that have ads, because on those games you have unlimited plays and can purchase their version of "premium" to get rid of ads. I'd rather have ads and be able to play as much as I want, or even pay one of those other games to remove ads instead of a deceptive one like this.

Love it!

Great concept of allowing a free game per day while offering the option to purchase for unlimited games. Interface and menus are clean and simple it seems like this could be a native app. Love the work you’re doing and maybe we’ll see some more not evil games from you in the future.

What the world needs more of!

Although I’m not the best soduku-r, the concept of no ad mobile games continues to be appealing. Something about not having to watch an ad every game / move / second makes it a pleasure to use, who knew. Truly all a soduku app needs to be

2 years ago, Jaboibangz

Almost perfect

Love the no-tracking aspect and the app is well designed. The one crucial missing feature is that pencil marks are inconsistent, in that they just show up in the order they are marked. Also, each square is limited to 4 marks. For hard puzzles, this makes the app almost unusable. With this feature, this app would be a clear 5 stars.

2 years ago, Shelby Baylis

Good start

Key features that are missing: Remove notes of numbers in a square after the number has been placed Highlight all iterations of a number in the whole puzzle when focusing on one specific number. Remove a number as a choice when it has been placed successfully in each square.

Awesome app

Great app, nice clean interface, and you can play without worrying about intrusive advertising and data harvesting. I splurged for the pro edition for myself and my wife to support the devs (and also to play unlimited games). Highly recommend.

Competent sudoku

It’s simple no weird popups for selecting number, leaving notes is easy, maybe some color coding would help but I bought the upgrade just so that I could play infinite games, so that says something, probably that I just like number puzzles…

Perfect Sudoku Game

This game is the best sudoku game I’ve played. No annoying ads between moves/games like the majority of them out there. You can make the games as easy or as hard as you’d like. Single IAP unlocks the full game and it’s reasonably priced. Kudos to the dev.

2 years ago, creadordepan

Pretty good

It’s sudoku, sedoku is fun, what did you expect? Although I will say the control are a bit confusing at first cause the game just throw right into to it but you get a hand of it real quick Another thing is the one day waiting time between games which was REALLY annoying at first but after a couple of days I really enjoyed that I had to wait cause… I don’t know, maybe it made the game felt more special cause it was the only one of the day? Idk Anyway Pretty good

I liked it but

Nice, clean sudoku app. I like the option to not show the timer, and I realize I’m picky when it comes to this, but I’d rather not be timed at all. If I were into the competitive side of sudoku, however, this app seems like it would be perfect.

Perfect sudoku app

It has an excellent UI, no ads, multiple difficulty’s, and just very good! I really appreciate the no adds! I bought the premium just to support the no adds! Get it if you want some chill sudoku! <3

Great app but issue with timer?

Design and gameplay is awesome and super easy on the eyes, but I only played one game and my timer is stuck around 9 and a half hours. Does anybody else have a workaround for this?

Best sudoku out there!

No ads, no tracking, clean interface. Congratulations to the developer for not being greedy - that takes a lot of restraint in these times.

Simple, nice UI

It's great game. Should update pricing. If someone has already bought plus version, pro version's price should change based on that.

Wish there was more than one game a day but honestly with no adds and challenging sets, this is honestly one of the first games I’ve seen live up to the standard

Not evil

This one is ad free for free, and you can unlock features for a one-time fee. Developer is active on Reddit and takes user feedback and input for new features.

YESSSSS!!!! YESSSS!!!!!! YEEEEEEESSSSSSS!!!!

Finally!!! An app that isn’t just riddled with constant noise, ads, dailies, or frustrations. A pure, clean, simple sudoku app with very convenient and easy-to-use controls and a nice range of puzzles. Not only is this app not evil, its maker is truly benevolent. I am delighted 🥰🥹

Decent but deceiving

It’s cool that there’s no ads but having to pay to unlock more puzzles isn’t cool. Bragging about “oh there’s no ads” isn’t a flex when you’re charging ppl to play more of the game. It’s a good game with a cool interface but having to pay to unlock the rest isnt worth having it on my phone at all.

1 year ago, Jubjub1389

Terrible and deceptive behavior

Imagine thinking that forcing people to pay to play more than one game of sudoku a day isn’t evil. Going back to my other sudoku app that has minimal ads and doesn’t try to deceive me. (Putting the “one game a day” information in the last line of the description is not being up front) congrats on still making evil sudoku!

Works really well. Definitely a couple features I’d like to have, but overall it’s great and I really enjoy it.

12 months ago, Ftggthyeherd

It’s true that there are no ads, there are a few things behind a paywall. But the most frustrating part is that if you don’t pay them, you’re limited to 1 game every 24 hours. Why? I’d rather deal with ads at that point.

2 years ago, Evster0220

Outstanding!

This is good old fashioned sudoku! A great pass time or and challenge to beat your old time(s). Plus zero ads?!? Outstanding!

1 year ago, WilllyDilly

Bad game

it only lets you play 1 game per day. I’ve seen the developers reference a “small one time purchase” for unlimited plays. But the purchase is 5 bucks which in my opinion is not worth it to play sudoku and especially when there are websites that let you play freely and unlimited with no ads

2 years ago, horndogaz

one thing

i love sodoku. ive been looking for a version of it but all then seem to have adds or a certain number of mistakes you can make. this game is the perfect version. no adds, simple, and to the point. however one thing i wish they would add is a function that allows you to check whether the cell is correct.

2 years ago, whatthehellisahufflepuff

Great but could be better

This app is a great idea. I love how it helps you play the game but I wish I didn’t have to wait a day to play again because I don’t want to pay for the unlimited plays.
