  • 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?

    Overall it's okay. However, my second puzzle in I reached a valid conclusion and the game said it was incorrect; it just happened to be that I ended with only two rows with matching pairs remaining. Both my answer and the game's "default" answer were correct, but it forced me into it's default answer to end the game.

  • 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.

    Good variation of sudoku. I have yet to win one of the events. They are too short for me. I always run out of time before completing all of the puzzles. Can you please make them a couple days longer?
  • 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.

    They took a fairly difficult game and made it so easy a toddler could beat it. Stuck on a number? Its ok some quick addition will fix that. And they have the balls to call it "killer". I thought this would make Sudoku harder instead it made even the hardest puzzles a medium at best. Id give a zero but it wont let me. Thanks for killing Sudoku, oh wait maybe that's what the killer means.

    It really sucks that you can't turn off the answer checker, so if you go to put in a pencil mark but forget to toggle on the pencil, you know if that answer was correct or not, so it doesn't really let you solve the puzzle on your own. I also sometimes hit the wrong number by mistake and and up with errors that way too. Too bad because the game is good otherwise, this feature completely ruins it for me. Uninstalling.

  • 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.

    the advertisement for this app clearly stated that there were "no annoying ads" and "no in app purchases" yet there are both ads and in app purchases that are subscription based. it is one thing to have ads or in app purchases on a free ap but my god at least be honest about it.

  • 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!

    I absolutely love this game! The only thing I'd change, especially for beginners is the fact that you only get 3 chances. I think you should be able to erase as much as you need to (if you need to at all). I am still a beginner, as I've just started playing this a few days ago while our power is out due to the snow/ice storms we've had this past 2 weeks! 👍👍👍👍👍

    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!

    Killer soduku is I think waaayyyy better than regular soduku its way more easier, fun, and sharpens your mind I recommend this for people who have a lot of stress in their life about work, kids, or just everything and you can play it anytime anywhere and there are barely and ads.

    I love this game because I'm proudly apart of the sodoku community, but I'm not the best at the puzzle. It loses the one star because if you get 3 things wrong it ends the game. Most of the time I miss click because of my fat fingers and it doesn't give any mercy.

  • Crash after crash Feb 4, 2021

    By Gillabee
    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!

    My only complaint is the game will disappear for a few seconds slot of times. It finally didn't come back. The easy puzzles are very easy. And I'm starting to solve the medium. My other complaint? Twice I've entered a number by itself. It shows up as a mistake. But I had no way of knowing that before hand. So I'm deleting this.

    I would give this app five stars, but I'm so sick of the Messenger ads! Make those go away and I will give it five stars. It's a fun way to learn Sudoku.

  • 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.

    Great game, but two problems. First, there is supposed to be an option to turn off the mistake notification, but for some reason it doesn't work. Finding out if one is incorrectly placed is cheating, so this should be off by default. Second, I have to force stop the game every time I finish playing. I exit out, it confirms that I am quitting, but then my phone notifies me that the game is draining the battery, so I have to force stop it. Otherwise it is a good game.

    It is so small I can't see it even with reading glasses. A very fun game and challenging. I would enjoy it so much more if I could see it. I have a Samsung fold the largest phone screen available and I don't normally need glasses to read.

  • Too many crashes or you would have a five. Feb 26, 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
  • Great game but not very stable Jan 17, 2021

    By cdnwetzel
    Literally every time I watched an ad I was stuck on a black screen, forced to quit, then had to watch second ad to continue which is great if you’re paid for every ad I watch but it annoyed the heck out of me as the player.

  • 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
