Killer Sudoku +

Challenging and good value for money. The interface is easy to use

I am totally addicted to this game! At first, I thought the easy level was hard. Now onto Extreme level, and determined to complete each puzzle without guessing. $1.49 for 100 puzzles will keep me going for a very long time. Love it!

First screen is straight up payment portal. Lots of good sudoku apps out there that give you a chance to assess before big $. Avoid this one.

I just started learning this game mode a couple of days ago and I’m hooked. The easy levels are still kind of hard but helped getting used to the rules, medium is ok, hard is well hard and sometimes can only be solved through guessing haven’t tried extreme. You get 10 puzzles for free and have to buy more (I recommend the mixed packs). Only problem is a lack of tips and tutorials nothing mentions the 45 rule and the hints give a random number with no explanation apart from that great app.

Great. Well crafted puzzles, and the interface has everything you need. Really great work, devs! The perfect killer sudoku app.

No matter how lightly and briefly I touch a cell, it puts in the final number, instead of a pencil mark. Also, although it says that pen marks are disabled when multiple squares are highlighted this isn’t true. Unusable

Game works well and like the design and like that there are so many puzzles to choose from.

This game is ruined by the inability to hide game menu. Requires constant scrolling to see all parts of the puzzle.

I use it every single day. It’s massively improved my maths skills, and it keeps my thinking fresh, whilst at the same time providing a perfect retreat. Thank you. One small thing.i have bought multiple packs from you - but having just had to reset to factory settings after getting my charger port replaced, they have all disappeared when i restored my ioad. Hiw do I retrieve my packs please?

I downloaded this app because it doesn’t track me or share my data. After playing the free puzzles for a while, I paid for a bundle of new puzzles because I really like the app. For me, this has everything I need from sudoku, with the right level of easy/hard and a range of options, all of which can be turned off or ignored so I can play how I want to. As someone with dyscalculia this is really appreciated. You can start each puzzle with no help at all, no “starter” cells filled in, or I can fill in some cells one by one until I am able to get started. This works even with easy puzzles. It’s a level of control over each puzzle I haven’t seen in other apps. The only thing missing for me that I’ve seen in other sudoku apps is the option to highlight all cells filled in with a particular number. As someone who struggles with numbers, especially with seeing all the same numbers, I’ve found that a really useful feature. But I get that most people aren’t like me! Thank you to the developer for respecting my data privacy.
