Killer Sudoku - Brain Games App Comments & Reviews
Killer Sudoku - Brain Games Positive Reviews
Game-yes Ads-NOI 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..Version: 1.3.8
Hints disappearedI love this game, it’s a good challenge but I had watched soooo many ads to build up my HINTS and now they are gone? What happened to my game? It’s like it was over written! I have been playing for a few months now and not only are my hints gone but it shows that I have only played one game? A screen popped up that asked what best describes me I’ve never played sudoku I’ve only played classic sudoku I’ve played killer sudoku I was playing killer at the time and I had no choice but to pick one of those 3 choices. There was no exit button. So when I picked I’ve played killer sudoku it took me back to a game and erased all my past history?? WHY?? How can I get back to where I was before that happened?.Version: 2.0.9
I was robbed.Playing the Auutumn challenge, had completed phases 1 & 2, and had 12 puzzles left to play on phase 3. While playing game 52/64 the screen froze on a Free Cell Solitaire ad. It wouldn’t move. Clock wouldn't wind down. It just sat there! So I exited, turned off my iPad and rebooted it. When I got back into Killer Sudoku it had wiped out the 52 completed games and set me up to play game 1/64. With only 1 day and 4 hours left in the challenge there is no way I will complete the level, thus ruining my completion score. I am very disappointed in the game. I had just downloaded the newest version of the game yesterday. So, I am not a happy player right now. F. Harless.Version: 2.9.8
Was fun til ads took overAs of April 2025, Somehow ads took over and 90% of the time when I open the app to play, an ad appears and there is no way to close it. It doesn’t even go away after a minute. I have closed the app and reopened it, that worked maybe 40% of the time, either opening the app to let me play or displaying an ad that can be closed. This happens again after I complete a game. And when am forced to close the app, I loose my reward I earned in the game. I have deleted and reloaded and still having this issue. Before this problem, I really enjoyed this app, but now, I am deleting it and will find a different app..Version: 2.20.1
Meh, and stop with the mid-game adsThe game play isn’t half bad. I like that it won’t allow you to make an errant note. However, I do miss the Fast Pencil feature that their regular sudoku game features. I also find that it lacks compared to Easybrain’s version, as they will color the board by sum, which is very helpful. But my biggest complaint is that recently, out of nowhere, I’m getting Candy Crush ads in the middle of a game that cause the app to crash. And the killer sudoku doesn’t present enough features to pay for, as opposed to the regular sudoku subscription..Version: 2.8.2
BattleThe Battle mode has the potential to be great, but has a couple of major issues. First is the ads: you get an ad before each match, but they are all different lengths. There’s been many times where I’ve finished my ad and my opponent had a shorter ad and placed 5-10 pieces before I could even see the board. The second issue is the matchmaking. I’m usually getting 3 times more wins than losses, because I’m getting put against people who seem to have never touched the game before. Despite these issues, I believe the battle mode has some great potential and hope that the devs see this feedback..Version: 1.10.2
Too many AdsI love the game but the Ads are driving me crazy, not just because there are too many. The “x” to close the app is too small so you can’t close the Ad but must go back and forth between the Ad and download screen. Also, if you do nothing and let the Ad run it’s course, it just stays on the screen. It used to have one Ad per puzzle but now you get an Ad when you start a game as well as when you end a game. I suggest finding another version of this game..Version: 1.16.1
Add Fast Pencil before I cryYour Sudoku games are top tier but ever since you added Fast Pencil to the main game I’ve been spoiled. It’s also the only way I can play with my Apple Pencil, otherwise it forces me to write in and then I mess up because my 7s and 1s look the same lol. Anyways I will keep checking this game for Fast Pencil but will be playing the main game and the Killer Sudokus you have on there with the fast pencil until then. I can’t wait!!!.Version: 1.11.3
Fun but glitchyI enjoy this game a lot, and I was psyched when the “battle” feature appeared yesterday, but I’m very frustrated by the fact that I open the game after being away from my device and find that I have “lost” several battles and my tickets for continue playing have been spent. I also appear to both lose AND win a battle now and then, and my statistics show both results recorded. Not sure how long I will stay with it under the circumstances, which is a bummer because I enjoy the game a lot when it’s working properly..Version: 1.5.2
Great game for reluctant sudoku-er who need cluesI 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..Version: 1.3.8
Great game-Terrible adsGreat game and I can wait through the ads to play again but I don’t understand how they get away with ads that are total lies. A powder you mix in water and drink twice a day and your fat will melt away? Really? They even show a video in reverse to show a dramatization of fat disappearing. Then there is the one that you can win thousands of $$ with videos from 8-10 years ago..Version: 1.6.0
Bad weight loss adsWhy do you keep showing weight loss ads that are known to be scams? I just fact checked “Oprah weight loss gummies” and there is no affiliation with Winfrey. Her image is being used without her permission. I hate all the weight loss ads, because they are all clearly fake, but lying ones claiming that they are endorsed by a celebrity when they are not borders on illegal..Version: 1.13.1
It Drives me CrazyI have loved playing this game until the last few weeks. The app freezes up every few seconds or goes to a black screen. I then have to restart the game and everything I’ve entered is lost. I have played one of the daily challenges 5 times because it starts all over. Also, the daily challenge game is not prefilled and I have to wait a couple of days to play it. Please fix these “bugs”, I would hate to play a different Killer Sudoku app. Thank you..Version: 1.12.11
Battle has been sketchy latelyI love this app! Recently, the Battle mode has been occasionally giving me a blank screen and no opponent. I’ve left those games and taken the loss. I just completed another battle, and won, then it put me on the blank screen so I had to take another loss. I know these are glitches, and they will be corrected, I’m sure..Version: 1.12.5
Bad adsI love this app and play every day. However I am getting very frustrated by the 2.5 minute ads by Gundry. I know you don’t control what ads are on but this is ridiculous. I’m getting so annoyed with this that I want to find a new app. PLEASE to something to control the length of ads permitted. Thank you.Version: 2.35.2
Good game but now interferes with AudibleI love doing brain games while I listen to my audiobook and fall asleep. I’ve been playing this game for the last 6 months with no issue. But lately this app keeps pausing my Audible app. Which ends up upsetting me and keeping me awake since I keep having to go back to audible to hit the play button. Since this is the only time I really play this game, I’ll have to switch to a different app until this gets fixed..Version: 2.10.2
Virus AlertAnd the virus is McAfee. I don’t possess McAfee on my device but I can’t play a game without it dropping me into a McAfee scan. The only solution is to delete your app. Bye bye. So I tried it again and no more McAfee and because I like the game and things went pretty well as the ads were bearable for a while but lately not so much. In fact the ads seem like the only reason to come and its a fight. There’s no turning them off or geout of them. I’m done.Version: 2.17.0
The Battles are great!Great twist on Sudoko. The battles add a great competitive aspect. My only issue is some of the advertisers will use a tiny “x” in the very corner of the screen that is impossible to X out of in order to play. It is really 1 advertiser. The only way I can close the ad is to end the game. It’s a big issue when it occurs in the battles. When that particular ad appears, it means I automatically lose the battle..Version: 1.10.1
Need to be able to win more hints!!I love this game—and it actually feels a bit like I’m using my brain, which makes me feel better about all the time I waste playing! But… every time I step up a level (I am currently stuck on Hard), I am in desperate need of hints before I improve. I don’t do battles, so I’ve amassed over 100 useless tickets. I NEED HINTS, though. I suggest allowing us to buy hints by watching ads all the time not just every now and then; giving us the choice between rewards of battle tickets or hints, or even selling packages of hints (though I would never do that). Meanwhile, I really am addicted! GREAT game!.Version: 1.10.7
Perfect puzzle game!Love it all. Would be a good addition in Battles mode if they add a flash when you complete a number! Would be an aid to the player and a cool visual to confirm there are no more of that number remaining. Currently the player must look down to confirm the number has disappeared. Maybe even a slight phone shake 🫨!😃.Version: 2.8.7
Too many crashes or you would have a five.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.Version: 1.3.10
It makes me thinkI concentrate on numbers and my mind lets go of the million things that go through it, just for a few minutes a bay. Then I can focus more clearly on other things one or two at a time..Version: 2.0.9
Recent changesLoved this game because it only gave advertisements between games. I wouldn’t mind several (3?) between games. Now doing a killer it breaks away every couple of minutes while you are trying to think. I may continue to do the daily but am looking for a different app now..Version: 3.5.1
Love game but need link to calendar brought backI love playing the game but I miss the link to the calendar. I start a game and sometime don’t come back for a few days. The only way to resume a game from another day is to start the game for today and go back to get to calendar to pick which day I want to play. Please bring it back!.Version: 2.0.0
Like the Game New Update Makes Ads WorseI play the game regularly. I like the combination of sudoku and math. But the latest update the ads often hang and have to be watched more than once. Sometimes the game glitches for the banner ads to load - not registering my tap and having the number enter on the wrong square..Version: 2.0.0
What happened!?!?!Love this game sbc the different levels of challenge. I’ve been playing it for several years. Now, however, the game goes to blank screen after game is completed and I have to exit and restart the game. It has gotten progressively worse! Please advise… I’d hate to leave this way to use and fun game but frustration level is going from Difficult to Extreme!!.Version: 2.12.2
Horrible adsAfter each game, ads for other hames come up without a way to exit. Every click goes to the get app screen. Can’t get out of the ads, and after 1 game and 5 minutes of ads I give up. The game is excellent but not worth the ad frustration..Version: 3.3.4
What did I just get into?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?.Version: 1.3.2
Love game but too few gamesSuch a fun puzzle game. Only problem is that after playing for a few months I have the dozen or so puzzles almost memorized. It reduces the challenge to say the least. I will continue to play, hoping that you can increase the number soon..Version: 2.14.3
Great Game - Technical GlitchThe game will not recognize the “1” key when in Notes mode. Doesn’t happen all the time; but only effects the “1” key. Have to close and restart the app in order to use the “1” key and continue the game..Version: 1.14.0
Fun… But a Challenge!First of all… I LOVE how on an iPad you can now use your Apple Pencil (Both Generations) to Scribble your numbers in and turn it to Text! Otherwise, if you are an iPhone user or dont have the Apple Pencil, You can still have fun with this Brain-Twisting App! Thank You!.Version: 1.12.8
What the what?I play this game on my iPad and prefer to play in landscape mode, not portrait. Reloaded the game after a recent update and now the numbers are piled on top of each other when in landscape. So it’s taken the perfect game and made it less so..Version: 1.12.3
Best I’ve triedI’ve tried a few Killer Sudoku one and like this one the best. I liked the idea of the coloured one, but shaded squares looked like different colours. This one moves quickly with few ads and auto completion..Version: 3.4.5
AmazingAmazingly fun game! This is the only sudoku app I have and I play it multiple times a day. Only complaint I have is the same as others’: price is too high. Wish it was a one-time payment..Version: 2.49.0
DiAds constantly freeze game…all stats are lost.Version: 3.3.2
Ad BugPlease fix ad Chartboost as it hangs the game..Version: 3.0.0
So tired of the bugsWhen I load the daily game, 3 out of 4 times it loads without numbers in place. The only fix is to restart, and each time you have to watch an add!.Version: 1.12.1
Great app but nasty monetizationThis is a great app with good puzzles. My only gripe is the price: there is no way this app is worth $20+ per year. A one time payment would be fine, but not recurring..Version: 2.37.1
Good game - app stopped workingThis game was very enjoyable, but it stopped working for me and just crashes shortly after opening now. Tried everything: rebooting, reinstall, but to no avail. Shame, as I quite liked it..Version: 2.29.0
Choose levelWould like to be able to choose level of difficulty in daily challenge.Version: 2.0.9

Bon pour la mémoire lovePour passer du bon temps Victor 1er.Version: 1.10.0
Needs another note colourThere are times where I need to mark a square as NOT a number, but I can’t fill it in yet. Another note colour—maybe in red—would make things more pleasant..Version: 1.8.0
Why change a good thing?It use to be better when it indicated best time, now it shows best time of the week which resets every week and we lose our best time overall. If you want best time of the week just add that feature but keep best time overall..Version: 1.6.0
