Contact Killer Sudoku Support

However the last update seemed to add some problems! First, they found a way to force you to watch even MORE ads be adding them into the middle of each game. You complete some numbers and are forced to watch an ad. Frustrating! And not sure if watching the ad adds to the time it tracks to solve the puzzle. Second, and a more serious issue, playing this game causes some serious drain on my phone battery and processing. My phone sometimes s l o w s down noticeably and the battery will heat up - so there is some serious processing going on in the background that is causing this! And I’ve tried ONLY having this app open, nothing else, and still have this issue, so it is definitely this game that causes it. It is so bad that on 3 recent occasions my phone has just locked up and I had to shut it down and reboot. One of those times I had to Google how to force a reboot because it would not shut down! I’ll move on to another killer sudoku app until maybe this issue is fixed in an update. Until then, downloaders beware!

Below is a review I wrote a couple of weeks ago. After seeing developer comments about removing the mid-game ads, I stuck with it a while longer. They haven’t kept that promise, so I’m done. There are plenty of other Killer Sudoku apps, and I’m switching to a new one. This has been one of my daily go-to games for some time. As a game it probably deserves four stars - it generally plays well, but the keyboard interface for numbers, notes, and hints is clumsy and I, at least, wind up taking hints when I’m trying to do notes and so on. It’s a relatively minor irritation but enough to cost a star. Recently, though, they’ve added ads in the middle of a game. For a timed game with the level of concentration demanded by killer sudoku, this is completely unacceptable, and it’s not like there aren’t other killer sudoku apps out there. That immediately takes the app down to one star. If they want to run an ad before the game that’s one thing, and all part of the story. If this practice of running ads during the game persists much longer, I’ll be finding a new app for this.

I’d like to start off by saying I really love this app; I downloaded it after normal sudoku got too easy for me, and it’s been a fun way to challenge myself. However, a few weeks ago my phone started freezing while I was in the app, forcing me to restart it. It was a relative rare occurrence, at first, so I kept playing (there’s not much else for me to do right now in quarantine), but it’s grown more and more frequent until just now, when it crashed twice in ten minutes and the second time almost bricked my phone. (My phone made noises when I tried to restart it. It’s never done that before.) I’m deleting this app for now for the health of my phone, but I’d like to please beg the developers to fix whatever this is. I don’t know what causes it, as the crashes appear to be completely random. I have an iPhone XR, and both my phone software and the app are updated to the most recent update. I’d be more than happy to change my review once this issue is fixed, but for now I’d advise people to be wary downloading this app.
