Sudoku ▦ Positive Reviews

A M A Z I N GThis game is such a good time-passer! I love how it is so fun and easy to play. It has different levels for each individual person. If you are not as skilled you could play one of the easier difficulty. Personally I like to play the “easy” level. There is harder one where you have 3 mistakes and you’re out. The easy level does not have that on it, which is why I like to play that version. But I like the other ones too!! The game is so fun and my go-to app for entertainment. I highly recommend using this game if you like brain-testing games!! I could go on and on about how much I love it because I like writing but I will save you the time and just stick to what I got already! But again such an awesome game and HIGHLY HIGHLY recommend it for anybody who has free time on their hands or just for anybody who likes playing games lol. Also this game could be good for your kids! Because it also tests their brain but at the same time entertains them and leaves you alone (if you are a parent). Thank you for reading to the end!!.Version: 2.4.8

Would RecommendSurprisingly intuitive program with a clean, simple interface. I do sudokus to relax, and this app seems to work well for that—you can do daily challenges, but it doesn’t feel like it’s pressuring you in any way. The only thing I would keep in mind is that this app will let you know as soon as you make a mistake, and it will only let you make 3 for a given puzzle. Not sure what happens after the third one, but if you’re the kind of person who wants to do it all on your own without help/hints and find your own mistakes, that might be a consideration. There’s a very convenient “Notes” function you can turn on/off with one tap which lets you write whichever digit you think fits in a box before committing to it, so that frees you up a little to “pencil in” your best guess and see if it works. The Expert puzzles are challenging and the Daily Challenges are relaxing. Would recommend..Version: 2.4.6

Sudoku: Loads of Fun & Therapeutic too!After having had 4 mini-strokes, I like to keep my mind active. I have trouble with my short term memory but with sudoku I can see where all the numbers are & figure out where to place the next number. If I can’t find where one number goes I just look for a different number & keep on going until the game is totally completed. I used to buy books of sudoku games & pencils by the box, along with a pencil sharpener & a good eraser; but this is so much better! I never have to worry about breaking the point off of my pencil, Or spilling the pencil sharpener’s shavings all over the place, Or forgetting where I put the puzzle book or my pencil when I want to play a game. It is right here on my phone & even if I receive a phone call, I can talk to whom ever & then go right back to my game without missing a beat! I LOVE it! Thanks!!!.Version: 1.3.2

Perfect Game-Option to Remove AdsThis game is my favorite way to pass time. It’s a part of my morning routine to complete the daily challenge when I wake up. I enjoy the free play (Especially since it does give you the option to see how you compare to other players). I wish there was an option to remove ads from the game. I would be willing to pay for this. I also wish there was a way to save progress. I am concerned if I ever get a new phone that all my stats, daily challenges, and journey awards would be lost..Version: 2.6.4

RuinedI have been enjoying this game for some time now. Today when I opened it up to play the daily challenge, I find I’m forced to play four games, three of which I really don’t want to play. Not only that, but the banner add, now placed across the bottom of the screen, covers part of the boards I am trying to play. Why do we have to ruin things with someone’s idea of an upgrade when the game as it was played was just fine? Can the ad placement be placed so it doesn’t cover part of the board (at least on an iPad Pro 11”). And can we be allowed to choose which of the four daily challenges we want to play, instead of being forced to play all of them? Just sayin’..... Update: the ad covering the bottom of the puzzle has been corrected, thank you. Still don’t like being forced to play puzzles I don’t want to play. On the other hand, it’s still a good game..Version: 2.0.1

Play on airplane mode to eliminate adsI always do Sudoku puzzles when I am waiting or doing stuff that doesn’t require much attention. The puzzles on this app are great—challenging but not impossible. The hints button is helpful. I’d love it if you could load all options to skip the tedium of adding them all yourself, as the interesting parts of Sudoku for me is the analysis once all the options are noted. This app does gives good feedback on how well you did on each puzzle, including the percentage of people that didn’t do as well as you did. I discovered that when you play on airplane mode you don’t have to put up with the all too numerous and tedious ads that take a long time before you can skip. Without so many annoying ads, I’d rate this 5 stars..Version: 2.6.2

Great Sudoku appI’ve tried lots of different Sudoku apps and this one is definitely my favorite. It’s simple to learn and the graphics are easy to read. I play it daily when I have a few minutes. I would give it 5 stars but the ads are driving me crazy. If I look away from my phone for more than a few seconds a silly ad will start playing. And the ads aren’t short- it’s a full fledged commercial about apps I don’t want to play. I would gladly pay to purchase the app and avoid the ads if that was an option. Please consider adding that feature. One glitch is that even after I have turned off the “3 mistakes” option, it still makes me watch an ad if I ever make a third mistake..Version: 2.6.4

Too easyAs a long time sudoku junkie, I’m picky about my apps. I personally love this app and the way you can easily switch between pencil marks. I also love how simple the app is and that it runs quick and smooth. The only two downsides I’ve found so far are: 1. You can’t cancel the excessive ads. I would gladly pay a dollar or a few to permanently remove the ads, but there isn’t an option. Not to mention, I get an ad every time I end and start a game. 2. As with many sudoku ads, Expert mode is far too easy. I can finish it under five minutes without even having to find hidden triples or use any special techniques. Just a few simple pencil marks and it’s over. I wish they’d make it a little more challenging on “Expert” mode..Version: 1.7.4

AdsThe game is fantastic - but the option to have a paid, no ad version should be there. I have no issue paying for a good game, which this is. The ads are the only thing taking away from my experience. Otherwise this is a 5 star game without the interruptions. Will absolutely buy if this option/version is released. Edit: So looking through other reviews, it looks like this is the number one issue being mentioned. Please seriously consider the paid option to remove ads - it’s a nice sentiment to try to keep the game free, but what point is there if it becomes unplayable, which it is due to the constant ads popping up? It literally is the only thing holding back an otherwise great game you guys made..Version: 2.2.1

RecoveryI love this game! Last year i have a stroke at 44 years old. My world was upside down im still recovering. Im lucky to have a strong family that has been with this would time. I had to relearned my abc and numbers .... i could not recognise numbers thats when doctors had me challenged my brain with reading , puzzles etc. i spend not hours days with sudoko, my daugter bought me sudoko puzzles , she got tried of going to the stroe so she downloaded this sudoko app. Every morning i get up pray and next i spend hours with this grae app..Version: 2.6.1

MISTAKE LIMIT!!So personally, I really like this app. I really want to play Sudoku in memory of my grandmother, so that’s why I got this app. I enjoy everything they give you and all of the choices. But the mistake limit is driving me CRazy! In my opinion, if you are a beginner like me, you should be able to disable the mistake limit. Now there is an option in settings, and I would press it over and over again to disable it but the mistake limit would still be there. Please help me or fix this because now I have to watch a million ads just to continue my game..Version: 2.6.1

Great puzzle gameDefinitely a recommended game for almost any occasion. It doesn’t use WiFi so you can play it any time (For example, in a plane). It’s simplistic nature makes it easy to use. It is an overall clean game and a good layout. And it serves it’s purpose of Sudoku. Great game to play for a few minutes before you go to sleep. Again, definitely a recommended game. Absolutely marvelous..Version: 1.5.0

Great except one bugBeen playing this for years, love the levels and interface for Sudoku, also love the new dark mode and the new challenges with different forms of Sudoku. However, the feature to turn off sound effects does not work for ads. That means, for example, that if you are playing late at night in bed before going to sleep, or in a group minding your own business, a loud ad will eventually yell out at you, waking your partner or disturbing your friends (and really angering you so much that you take time to write a review). Please fix this bug!.Version: 2.1.1

Very good but too many ads and needs more featuresIt is a very good app that show per game statistics which make more sense than overall statistics. However it has way too many ads which spoils the experience. The app should give a way to buy an upgrade to stop the ads. The app also lacks some features that are annoying. The notes number pad doesn’t exclude the numbers that are already solved completely on the board. The themes don’t allow highlighting of all the squares that contain the selected number prominently which causes more mistakes..Version: 2.6.4

Annoying quirkMy only frustration with this app is that the time it takes for an ad to finish counts against my time in a puzzle. By the time I get through the ad to start the puzzle, I’ve already lost at least 10 seconds, and if I need to pause for any reason and restart, there’s more time lost to ads. I’m not complaining about having to see ads. I know it’s a free program, so that doesn’t bother me at all. I just wish there were a way to freeze the game clock while the ads are playing. Otherwise a nice program! Thanks!.Version: 1.7.4

Used to be a 5 until updateBefore the update this was a 5 star. Here is what I don’t like since the update. 1. Commercials are too long 2. You can no longer repeat the same game. Before if you made three or more mistakes you could request a new game and if desired play the exact game you were playing before until you mastered it. Now after three mistakes you only get a brand new game. 3. I play at night and sometimes when the commercials come up the noise is so loud and it wakes my husband. So I have to turn sound off to avoid that, which affects my alarm in the mornings..Version: 1.2.1

Great app! But...I love playing soduku when I’m just lounging in my house or when I’m just bored so this app is perfect since it has different levels! The only complaint I have is I don’t know why, but this app DRAINS my battery fast! It also makes my phone burn up so I’m not sure why because when I’m on another app, this never happens. I played for 20 minutes and my battery percentage literally fell from 50%-10%. Please take into account that I have a iPhone X that I’ve only used for around 6 months so that’s definitely not normal..Version: 1.6.1

Newbie loveSo I just started playing a couple days ago. I’ve downloaded a few games and I like this the best!! Math/ number patterns are very hard for me and thus very easy for me to feel overwhelmed. I had played some 6 number version that while easy I was used to in a few hours. All 9 scared me as it was really hard for me to see the pattern. The easy level of this game was actually easy enough where I quickly became comfortable with all aspects of the game. Thank you so much!! Never thought I could play this game never mind love it!!.Version: 1.6.6

I love/hate this app!The good: having played a dozen iOS Sudoku apps, I find myself gravitating to this one for its aesthetics and gameplay. The bad: there is no way to pay out of ads, forcing the use of ad-blockers with variable success. Many of the ads it displays are ones with loud, grating sound. I often play this game at night and it is very disturbing to those around me. I understand the economics of ad development but I will not patronize developers whose business model is the perpetual irritation of its fans. I’d gladly spend money on this game to eliminate its ads...but I am on the lookout for a better sudoku game than this one..Version: 2.0.2

Overall good game but the ads are annoyingI really like how it provides insights and compares your gameplay to the average of all other players, but the ads are super annoying. Especially since it times you, once I press start I get an ad that delays me by 30 seconds, and as far as I can see there’s no way to remove them. I messed around in the settings to look for a way to pay to get rid of ads but it’s not really worth it..Version: 2.6.4

Worst part: flashes really bright after you finish a boardI love the different color palettes for the boards, but the screen flashes really bright white every time you complete a board.. I use the dark color palette mode when I’m about to sleep, but the bright flash of light freaks me out and is very off putting. I think it’s meant to be satisfying/congratulatory but it hurts my eyes. 4/5 stars for that but will change my review to 5 if it gets fixed. (Sorry for putting that on here, the app support link was broken!).Version: 2.4.4

IOS has some issuesI love Sudoku and love the new four part daily challenge (although multiple ad breaks is discouraging), but here is my issue. I almost always get at least one error in a game because a new tap to place a number puts the new number in the spot I just placed a number. I like to time myself and this completely slows down the game. Not sure if it’s an app issue itself or just a platform issue or if it’s done that way on purpose to make sure you spend more time watching lengthy advertisements from sponsors. Ugh..Version: 2.1.1

Great app but lacking oversightOverall, I really like the app and enjoy the statistics given after completing each puzzle. However, yesterday, the second daily challenge puzzle contained a racial slur fully written out across the top of the puzzle. I would like to give the developers the benefit of the doubt and assume that this was an accident, but regardless there should be more oversight to prevent something like this from happening again..Version: 2.6.4

New update lost 2 starsI was loving this app. Love the new levels from 4x4 to expert. Lost one star due to ads bringing away from playing without me doing anything. Lost another and this is a big one Volume Control. The ads are so loud. They stop the other things I have going on like music or books. I would actually consider some of the games if they were not so loud. I usually turn off the WiFi but now the ads are still there even if I do. After plays 4-5 games this is so frustrating I go one to better games..Version: 2.1.0

Great game, now ads with sound during games!I absolutely love this app...yet I absolutely hate the ads with sound. Now during the game there is even a banner ad from apartments dot com that blares out and disturbs my concentration, while I’m competing against the clock. That’s the only reason I rate 3 stars, instead of 5. I’m probably going to delete the app soon if the sound doesn’t stop. I understand that the developers need to make money...but NO sound please! Even when a different, expected ad runs between games and I turn off the sound for it, the next has sound...specifically quicken loans. The aggravation of this insures that I’ll never use quicken loans! I’m caring for my dad and the sudden sound often wakes him. I like this app enough that would pay a reasonable fee for it ( not subscription, I never do that) but I don’t see the option..Version: 2.3.4

Too many adsGame is good. Hard and expert levels are not hard. The number of ads are absolutely ridiculous - some adds longer than it takes to play a game but still gas to be after each completion, and it is the same ad or two over and over and over again. It doesn’t matter if you can click on X after 15 seconds or so or if app is free, no need for add after each game when it’s the same ad..Version: 2.2.4

New updateThe multi part daily challenge is okay, but for goodness sakes the first two puzzles in it are exactly the same pattern. The only difference is one contains numbers, the other letters. I do really like the third challenge in that it’s a different format (1-6 rectangles rather than 1-4 or 1-9 squares), but wish they’d make it an option for straight gameplay instead as part of a long, drawn out, daily challenge. TLDR: new update is kinda tedious and teases us with what the app could be, but isn’t..Version: 2.0.1

Excellent puzzles, great player insightsI usually play daily, starting in the morning to get the brain juices flowing. I can solve puzzles faster now and have become more efficient thanks to insights provided at the end of each game. The option to play different layouts is intriguing and they are fun, but I usually find myself playing the classic layout....creature of habit, I guess..Version: 2.4.4

Needs paid ad removalI love that this game has statIstics. I was looking for a sudoku app with stats and was really excited to find this one! But I was spending more time loading ads than actually playing. I would love to pay to turn off the ads. I won’t be playing it again until that’s an option..Version: 2.3.4

Love the feedback….best Sudoku app, BUT….Love the feedback as you solve each puzzle, but the ads have become overly annoying…. I have no problem waiting for them to pass, but some of the ads you can’t get past…. Have to kill the app to get past…. Was not the case before, and this is taking away from the quality of the app..Version: 2.6.2

Concentrate, concentrate, concentrateFor Sudoku lovers only. Wonderful game that focuses your attention. This app has a decent interface, but I don’t see a way to reset a game so that I can start over if I screw up. !!UPDATE!! Yes, you can reset a game if you undo the “mistake limit” in settings. So this game is purt-near perfect, and I’m upgrading my rating to 5 stars!.Version: 1.9.2

Decent Sudoku, Terrible Battery DrainThe daily puzzles provide some decent easy/medium level challenge. You won’t have to do any particularly challenging strategies to beat them (e.g. X-wings or hidden triples), but it’s a solid app for what it gives. I did try their hardest puzzle and that still held true, not just the daily challenges. 3 stars given for two reasons: 1. The battery drain on this app is ridiculous. I spent <15 minutes on the app and it drained 10% of my battery. That’s just unacceptable. 2. The ads are really obnoxious. I get having ads to play, but this has multiple for each puzzle, and then you still have banner ads during the puzzle itself. If those things don’t bother you then it’s worth checking out if you like Sudoku..Version: 1.7.4

Please fix!I really love this game, I love Sudoko in general. But this is my favorite app to play on. Unfortunately, the only problem I have with the app is every time I finish a daily challenge it just sits on an incomplete circle. When I tap on the circle it will say resume game. So I hit resume game and it will be a completed puzzle... but the timer keeps going and you can not do anything with this complete puzzle. The game still reads as incomplete, so please fix!!!.Version: 1.8.0

Great game but......So this is a gr8te game but hard for stupid people like me. I not very good at it so I give it 5 stars for making me feel stupid..Version: 1.5.0

AdvertisementGreat game but I dislike the advertisements that pop up between games.Version: 1.7.4

MediumRare 🥩.Version: 2.6.4

How soon is soon?I do love this sudoku game so I've really been holding out for a journey...I've had this game for a couple months and it always says "the next journey will be available soon" how soon is soon?.Version: 2.4.6

Ads are exhaustingI would happily give the company $10 to not see ads. They are exhausting and never ending, and every one of them seems to have a different skip UI. Oh, and they love to steal audio focus - so that’s fun. Please take my money. Please!.Version: 2.2.2

Animated Ads make me crazy!I love this Sudoku game but the animated ads jumping around are distracting, annoying and break my concentration. They are especially bad when they take up almost a quarter of the screen and I have to close the app to get rid of them..Version: 2.1.0

Bad “update”I’ve loved this game for years and play it almost daily. Today I opened it up and the appearance has completely changed! Numbers are smaller, weird highlights and arrows everywhere. Super distracting, and I will probably look for a different game now. Colours are muted and the flavour is gone. Sad to see this..Version: 2.6.5
