Dinsun Expert Review

Our Expert Score

87/100

Sudoku.com by Easybrain is essentially the definitive version of Sudoku for mobile. It avoids the clutter found in many other apps and focuses on what matters: the puzzle. The 'Note-taking' feature is particularly well-executed, automatically updating your possible numbers as you fill in cells, which removes the tedious bookkeeping of paper puzzles.

The app scales beautifully for all skill levels. If you're a beginner, the 'Auto-check' and 'Highlight Duplicates' features act like training wheels. For experts, the 'Expert' difficulty and 'Fast Mode' provide a legitimate challenge. The Daily Challenges and Seasonal Events (like the current Dragon Dance) give you a reason to log in every day. While there are ads, they are relatively unobtrusive compared to other free puzzle games, and the overall polish makes this my go-to app for my morning brain workout.

Absolutely LOVE sudoku but . . .
Wed Apr 09 2025 S'mala

I’ve written a review a long time ago. Two things : There used to be no ads. Then you added some and people complained and you took some away. Now (and have been) back for a long time. Ok - I can understand why. What I can’t understand is why there has to be three or more pages you have to hit to get out of them. Why can’t you just have three different adds let us get out of each instead. My biggest issue is that I have arthritis and it is very difficult not to hit numbers by mistake. I’m good at sudoku. Yes - I’ll make mistakes but, more often than not, it’s that I’ve hit the wrong number because they’re so close. Also - you have to hit the exact spot to do notes and since you rush to finish your time, the note button will not always light up and it counts as a mistake. Please - just make it easier to tap the note button without having to hit one small spot that makes it go on. And I agree with another person - I’ll get a great score and time and get less than the times I make mistakes and have to watch ads. Even if it happens multiple times in a row and get a better score. It doesn’t make any sense. You seem to get punished for doing better. It seems to want you to make mistakes so you HAVE to watch ads if you want better scores. Also - while I’m at it and in a roll, why is it that no matter how long it takes me I seem to be in the 99%. Again, doesn’t make sense. This has all been going on for a while now. I should’ve written back when it changed. Thanks for listening

My go-to Sudoku app.
Thu Feb 11 2021 TV_Sucks

I play Sudoku on my phone, computer and in books and I would say that this is my favorite format. The app has a clean look and is very simple to use, yet also has extensive depth and functionality accessible through settings. This allows for tailoring to suit your preferred look or functionality. The events and awards give me a reason to keep using the app and offer a sense of accomplishment, supplemented by the statistics menu. However, I keep encountering an issue that, while not detrminetal to my experience, is still mildly frustrating. The issue is in reference to the "number-first input" setting, which allows you to lock a number by tapping and holding that number, in turn allowing you to use it for multiple cells. The issue that I experience is that while I have a cell selected which has a user-inputted number (a blue number) and attempt to tap and hold to select a different number, it will actually change the number that was in the selected cell. If I press very firmly there seems to be no issue. I am not entirely sure if the problem is caused by the app or my own device (iPhone 11), so I've given benefit of the doubt with 5 stars anyway. I will say, however, that my game statistics ("wins with no mistakes" specifically) are skewed for that reason, since the app will interpret that as a mistake. I would say that this issue accounts for possibly as much as 25% of my "mistakes" in total. I would love to hear some feedback as to whether this is an isolated (exclusive to me) issue or if others have experience the same problem. Thanks, devs, for a great app. Keep up the good work.

Pretty good app, default settings are terrible
Tue Jun 14 2022 ajj487

The game has a “correct/incorrect” solving mode which I am not a fan of, I’d prefer to solve a puzzle and check at the end to see if it’s solved and allow myself to find mistakes while solving instead of just immediately getting “BRAWP WRONG”. However if you do get a correct tile and then later accidentally note or input another number, your correct answer is lost and you take another incorrect answer, if this system is going to stay, correct answers need to be locked in and unchanging. Some of these things are changeable in options, they should not be set like this to teach/learn sudoku, it’s unintuitive and promotes winning over making mistakes and learning, especially the 3 mistake limit. Next thinking about solving tools, only one set of notes that gets very in the way and is locked to a grid orientation, especially on mobile that makes some sense but I would still love a highlight tool or a way to mark cells in more than one way with the same set of numbers, it’s far easier to keep track of patterns and observations that way. Also there’s way too many ads, you will never solve a puzzle without being interrupted at least one time. Removing ads is $5 and without the other issues I have with the app I’d be happy to pay, until then they’re asking more than most apps for something I can just close and re open the app to skip. That or stop selling your space to the worst possible mobile ads that are intrusive and you can’t exit out of them.

Bad timing for commercials
Fri Feb 23 2024 jaimeLynn25

I recently got into Sudoku again quite a few years ago I dappled in it now I have seven apps for different makers of the sudoku game. I’m gonna narrow it down to two or three that I like the most and I’m playing them back to back playing a couple games in each one until I figure out what I do and don’t like so originally I like this one the most because it was the first one I downloaded in this recent journey of getting back into it but what I’ve came to realize is it gives the ads at all the wrong times you’re just getting on a roll and it congratulates you if you finish a number or a cell or a block whatever and how it congratulates you by giving you an ad it’ll be like a cute little emoji congratulations way to go you’re doing great and then Bam you gonna add I understand these apps to be free have to have ads but it’s just all bad timing. Maybe if you mess up or something give you an ad give you an ad when you finish the game or when you start a new game something like that, I’ll try and keep track of what the other ones do but I’ve played the other ones all a few times and I was not annoyed with the ad so this must have the most ones out of the seven that I have and it’s super annoying because you just get on a roll, you got numbers in your head what you’re gonna play next and then you gotta wait for an ad and you lose it all in your mindso if it wasn’t for that, I would probably give it a five star

Ads and Statistics
Sun Apr 21 2024 SlitherinSloth

You guys used to run a lot less ads. I get needing revenue to continue running the app but I have pretty quick times. There’s no reason I should have to watch 3 ads for a 2:20 minute level. Secondly, I used to have a flawless statistic sheet across the board. 100% wins. Just recently I noticed I dropped to 99% and saw that I have 131 started and 130 won. But my streak is 130… that means I should’ve lost the first one I ever started and I never should’ve had 100% wins. Which means the loss was randomly added to my account. It’s also on the daily challenges which you CANT reset not to mention no one wants to reset 130 games. Please fix whatever glitch happened on my account so I can have my 100% back. I dealt with the ads because of my statistics, but with my statistics being skewed and now not flawless anymore; its not worth staying on an app I already have other issues with. Your generic computer response because you scanned the word “ads” has cost you a player. I may be a drop in the bucket but maybe enough people will get fed up with the lack of respect and the obnoxious level of advertising that ruins timed runs. The main issue, and most of my review has to do with the statistic glitch. And even if; I watch 45 seconds of nonskippable ads to play a 2.5 minute level. Having ads to run a game and being overkill are very different. I’d argue having close to a 1/3 of my time on this app being spent in adds is overkill.

Solid app, these features would make it even better
Sat May 04 2024 neinjamb

Worth the $5 for sure. If you play this game often, buy it and support the developers. Love the UI with the ability to quickly change the colors. Also the app is fast it doesn’t glitch or lag, allowing me to play fast. Some other apps are laggy and it slows me down. Please make the following changes: 1. The HINT button needs to be renamed. It is not a “hint” it just reveals the square. Call it REVEAL. 2. Add a setting to allow paying users to remove the HINT button. I keep accidentally tapping it 3. Create an actual HINT button that gives a hint 4. Make the “tournaments” real, with players competing against each other instead of a scoreboard full of fake users and fake scores 5. Prevent users from doing unlimited HINTS or reveals in tournament games. 6. This is BIG one that would make things so much easier. Please add a calendar selection feature so that players can easily browse to past daily puzzles. Currently players must swipe one month at a time. If I have completed the past two years worth of puzzles and want to play some older ones, I would have to swipe 24 times to get to the puzzles that I want to play! Take a look at the NYT Games crossword app and the way they handle the calendar.

If it’s not broken why try to fix it?
Tue Aug 08 2023 ketchupmilk

I loved this app but the sudden change to a new interface is really bugging me. There was no actual app update to indicate the change. There now is significant lag that is eating away at my times and making it so I have to touch numbers or blocks multiple times for it to register. The scoring has also noticeably changed and my new scores don’t even hit my previous averages. Less important but still worth discussing: Completing a block or a row is now less visually satisfying. In dark mode there still is a wave of blocks to indicate the completion, but it’s a wave of black instead of a wave of light, which makes it more difficult to see the effect and takes away some of the sparkle for me. I used to try leaving the center block blank for the satisfying ripple of total puzzle completion and now I’m not really as motivated to play seeing the kinda dismal wave of darkness. I do like the completed puzzle being displayed upon finishing, but i feel it is clunky to have to scroll just to see all the stats of the completed puzzle, when the original layout displayed everything in a completely fine way. (Edit: after seeing so many new comments about the ads getting worse I change my tune about paying for the app. It was worth it before but unless the update is reverted or fixed it seems like it’s downgraded either way)

Ad raging / horrible hints
Wed Jun 21 2023 Jaredchasedheraround

I am in no need of a sudoku game. I do enjoy it, but I do not enjoy 15-30 second ad pop ups interrupting my experience. It was actually taking away from my time to do other things so in a way, I thank you for helping me remove this app from my phone. Also what’s up with the hints? I was playing on expert and trying to get the hang of little to no details, I narrowed down the 3rd row from the top running horizontal. 4/7 in left box, 3/6, 3/6 in middle section, 4/7 in right box as well as other areas. I hit the hint and it wanted to say I didn’t have enough info in the inner boxes and added back the 4/7 in the middle. If I could show a pic I would. The horrible hint wanted to further confuse what I had simplified. How is someone to be more “advanced” if the hints are the opposite of useful? I later solved the puzzle with no thanks to the hints and also proved that only 3/6 would fit in those middle boxes. This wasn’t the first time I noticed this garbage hint. Though there were some moments when it would help me see where I messed up and how I should have reasonably seen a number I missed. So if the “hint” wants to add numbers to the uncertain boxes, you’d better screenshot it and double check. It sent me backwards on my progress
