  • Too many crashes or you would have a five. Mar 11, 2021

    By Sicilian Cook
    Please fix the crashes. Generally happens when I’ve made thee mistakes, the ad comes up and when it’s over I hit the X and the screen turn dark and just stays dark until I reset my I pad Thank you for fixing the problem, it’s a great game and I play it all the time

    Not sure if I want to keep this on my phone. They trick you like I am noticing most "free" games are doing more and more. It starts out fun and addictive. Then after a certain amount of time ads start popping up before and after each game. I understand needing to advertise to make money, but this is overkill. Yes, there is a way to pay for the ads to be removed. I don't feel like being charged weekly or monthly to not be bombarded with ads on a "free" app. Should have a disclaimer about ads.
  • Great game for reluctant sudoku-er who need clues Jan 29, 2021

    By Thusarik
    I never got into sudoku. But the boxes of “add this up to find this answer” that then helps fill in the puzzle are great. The only reason for only 4 stars instead of 5 is, I don’t like how you only get a certain amount of tries before it knocks you out of the game. I get to a point where it’s between two numbers, and I want to keep track of this knowledge, but I can’t, so I have to move onto a different line and lose that knowledge. On paper, you can write things in the margins. But then again, I’m not a sudoku-er.
  • Game-yes Ads-NO Mar 1, 2021

    By Kthon43
    I love the game. Much more fun and challenging than regular sudoku. BUT, I hate the ads!!! They are 30 to 45 seconds long before and after every game. If you re-start a game you have to watch one or two ads. There is no way to turn them off, skip to the end, or shorten them. VERY annoying!! I understand the need for ads and will tolerate 10 to 15 second spots before you play the first time, but the frequency here is just too much. I’m going to search for a game with less intrusive ads.
  • What did I just get into? Nov 24, 2020

    By [steven99]
    I am absolutely in love with this puzzle game. I like the math included in the puzzle, giving you a new way to puzzle out the actual answer. What a great addition to the game, subtracting my boredom without dividing my attention and multiplying my joy. Do you see what I just did there?

    Game is great, works perfectly. I wish it had the ability to load all the possibilities as notes, though, like Brainium's regular Sudoku. And maybe hints like that game.

    I used to do Sudoku by the thousands but never had to do math to solve them. I like having the extra step of addition that requires that I think. I just turned 80!

    I like this game. But the constant crashes are getting old! Seriously, I have to delete and reload this app several times a day. Will have to look for another version, because this is annoying!

    This is a fun app for a bit. The sudoku is great. But after about 20 puzzles or so, the ads get obscene. And the only way to remove them is via a subscription. $1 a week for some sudoku? No thank you

    Doesn't offer a perpetual ad free version. Would be glad to buy that if offered but it's not. Therefore, choosing a different game.
  • Apr 21, 2021

    By Bob Staff
    Loved this game at first. I accepted the ads that are understandably needed to support a free app. They were at the beginning and end of a game, and if you wanted to add more hints, etc. BUT the latest update not slaps ads in the middle of the games. Finish a cell- ad. Finish a row- ad. That's just taking advantage of your popularity. Uninstalled.
  • Apr 18, 2021

    By Jennifer Elizalde
    Just got the game and already upset with it 🤷‍♀️. I dont like the fact that the game ends once you make 3 mistakes. Just makes me mad. Making a mistake and then going to to figure out which one was wrong is part of the fun! Plus, what if you accidently put in a wrong number, whole game is over. Idk, it just doesnt make sense to me. Also, i thought this game would be more on the easy side considering it has groups with the sum of each group but more often than not, there are too many blank space
  • May 5, 2021

    By Gary M
    Too many freaking ads because all the daily challenges are the killer level. Bomb 3 times and then watch a million ads to solve each challenge. No one responds from customer service. Game has potential but its not worth watching all the 30 second ads for a wrong choice.
  • Too many ads. Too expensive (60$) a year Jan 4, 2021

    By cjpeters17
    The game cost for no ads version is sky high and gouging for these developers I tried to give it a one for a rating but funny it wouldn’t accept any combination of letters as a nick name. I tried to give it even gobbilygook letters. Really? Only when I changed the rating to a two. Thumbs down to developers and app to these ethically challenged developers.
  • May 3, 2021

    By Alexander Fort
    It was a good game. As soon as you complete a few expert level puzzles, all the daily challenges become expert level. They aren't hard, just annoying.
  • Annoying ads 😡 Feb 16, 2021

    By dapperapper
    I played this for 2 days and enjoyed it. Then on day 3 the ads started between games AND at the bottom of the screen. I wouldn’t mind ads in between games, but the ads at the bottom of the screen are annoying and make the game unplayable. And to the developer...you know what you can do with your subscription!
  • Offensive ads Mar 25, 2021

    By bizarrocat
    I love the game but I am offended by the ads. Some are political, such as an ad against liberal immigration policies that show former President Obama apparently hanging his head in shame. There are too many ads for violent games. The worst was a first shooter game showing a crosshair on a wolf (endangered species!) then the wolf falling over dead. That one really upset me. Please choose more politically neutral and less violent ads.
  • Love game hate porno ads Dec 25, 2020

    By Allyperr
    Great Sudoko game and challenging. But I keep getting this ad for Kings Throne - game of lust that really bothers me. I have to sit and watch these half naked girls bounce for 15 seconds. It’s the same ad over and over. All of the other ads are fine but of all the games I play this one really bothers me. Stop that one ad and I would give this game 5 stars

    Challenging games. It keeps your right-side of the brain very active. Only thing missing (or maybe I don't know) are the combination hints. But, still worth spending time.

  • Review Dec 7, 2020

    By Sarah Joos
    After the second game, I realized the summation total for x number of boxes. This option, while beneficial for some, removes the logic from this game and makes it HARDLY a killer Sudoku:/
  • Mar 1, 2021

    By Doll Doll
    This is a great exercise for my brain. I have suffered an accident ending up in some damage. As I played the first the game forces me to look at several points of view to solve the problem. I struggle with my tunnel vision and only see one option and this game makes look around and not to make an impulsive choice. Thanks.

    By Yhana Figures
    It's a fun game but I left after they started putting ads in the middle of the games. Annoying to stop the flow, especially when the games are timed. Before or after the games were fine but in the middle messed me up.
  • Nice game Apr 5, 2021

    By timmy tox
    Suggestions for improvements: 1. Use very different fonts (in color, size or style) in pencil mode, to reduce confusion with fill mode. Current changing to grey color is not strong enough. 2. Auto pencil filling would reduce tedious work in expert level. You can make it a pay feature :-).
  • Locking ads Mar 28, 2021

    By Scfoster
    Like has previously been stated, some of the ads just lock in place and I cannot continue with the game. I'm offered 3 free hints to watch the ad, but once the ad is done, i cannot get to the game. It stays on the ad. The only way to get rid of it is to reboot my ipad.
  • May 3, 2021

    By Rachel Drake
    The levels are well done, the added groups make even blank boards solvable. The ads are frequent, but can generally be skipped after 5 seconds.
  • Fun, but too many ads!!!! Mar 14, 2021

    By jane doeberg
    Game is interesting and fun, but way too many, way too long ads!!!! The ads will probably be the reason I drop this game.

  • Love the game. But not all the crashing Jan 21, 2021

    By katiebugbb8
    This game is so addicting. Thankfully it freezes up A LOT, so it makes you have to put it down. Unfortunately I have to restart my phone to correct the problem. And an ad after every game is very annoying especially the ones that are sort of inappropriate.
  • Mar 30, 2021

    By Alan Kennedy
    Forced ad watching after each game in addition to banner. Premium is pretty cheap, but I don't like the app itself enough to pay to remove ads. On the one hand, it's well polished imo, but on the other, the way it handles mistakes (telling you immediately when you make one) can itself be used to solve puzzles. Also, make three typos and you have to restart the puzzle (though this can be disabled for some puzzles).
  • Mar 24, 2021

    By T3hHappyEmo
    I see there is an option to turn off the game over after 3 mistakes, but I dont see any option to stop highlighting mistakes. Putting down a wrong number and then making more mistakes off of that, and having to backtrack and figure out where the mistake is at is part of the fun of sudoku.
  • Difficult to See Jan 29, 2021

    By 22Cool
    This is a great Killer Sudoku. HOWEVER, the little pencil numbers are VERY hard to see. They need much more contrast, and I suggest the game use a bright color for those tiny numbers. AND, the blinking adds are nerve-wracking.
  • Pencil entries are hard to enter & read May 3, 2021

    By Mastervestor
    The pencil entries are hard to see. Too much eye strain playing this version of sudoku. There are better versions available that are much easier on the eyes.
  • Good puzzle, but... Feb 15, 2021

    By bmosh42
    I really enjoy the puzzle. I appreciate the fact that commercials support the puzzle, but am frustrated that the commercials are so lengthy. That’s why I gave 3 stars instead of a higher rating.
  • Great game; adverts get stuck Nov 26, 2020

    By Mimi_spirit
    Great game. Easy to follow. Sometimes the ads get stuck and you can’t get them off your screen for days and you have to re-install the app.
  • Limited mistakes? Feb 15, 2021

    By HSMathews
    I enjoy traditional Sudoku and have found this version challenging. My only gripe is to be penalized for mistakes. After three you get closed out.

    The number and length of ads in this app is excessive and ridiculous, and the cost to remove them is absolute highway robbery. Whoever is in charge of these decisions should be ashamed of themselves.

    The game play is fine although the graphics could be improved for older eyes. The primary complaint is the politically biased ads.
