Description
Killer Sudoku is a fun and challenging variant of Sudoku. If you love Sudoku, why not give Killer Sudoku a try?
As with Sudoku, the objective of Killer Sudoku is to fill the grid with the numbers 1 to 9 such that each row, column and nonet (3x3 group of cells) contains each number only once. In addition, a Killer Sudoku grid is divided into cages, shown with dashed lines. The top-left corner of each cage shows the sum of the numbers within it. The same number cannot appear more than once in a cage.
There are ten puzzles included for free, and thousands available for download. The puzzles are graded into difficulty levels, all excellent quality and with a unique solution.
The app and puzzles are from the maker of https://www.dailykillersudoku.com.

Ratings and Reviews
Great sudoku app with no tracking!
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.
Best for experts
I’ve bought all the 100 packs of hard and extreme puzzles in this app and can’t find another app to match this one for a challenge. This app demands skill with the numbers and sometimes it takes me 15 mins and sometimes an hour. I think I will have to buy the 500 pack although presumably there’s overlap with the 100s that I’ve already done.
This app is also better in use than other apps: you can type number options in cells and select multiple cells. It also gives number options although I try not to use this.
Variations
I enjoy the problems, however, I do find that problems, which are supposed to be of similar difficulty, can take from as little as 30 minutes to over 1.5 hours, a small number never being finished but abandoned.
I can spend/waste a lot of time every day on them!
