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
Very well designed
I’m sort of addicted to this app. Killer Sudoku is a pretty complicated game, requiring the player to keep track of many possibilities. This app provides a lot of useful aids. For each cage, the app provides all the sets of numbers that are possible for it, and you can uncheck sets as you eliminate them as possibilities as you go along. You can, of course, enter “possible numbers” as notes in each square, or across a selection of squares. You can select more than one cage and the app will automatically tell you the sum of all its squares. There’s also a “calculator” that allows you to enter an arbitrary cage size, and it tells you all the possible combinations. There aren’t very many killer sudoku apps on the App Store (I know of two for certain), but this is easily the best one. It offers many sets of puzzles as in-app purchases, in a wide range of difficulties; since the harder puzzles have lots of replay value (unless you have perfect memory, I suppose), then a few of these purchases will last you a long time.
Can’t down load the extra game
Tried it on my iPhone and iPad and neither will let me down load the extra puzzles. What’s more, it tells me there is an error and will not let me cancel it. So I have to delete the app every time and reload it again.
Good games, but useless app!
Developer Response ,
Thanks for the review, and sorry you've hit this problem. It's fixed in version 1.5.3.
my favorite killer sudoku but would like some features
I have tried several killer sudoku app and like this one the best generally. But I wish it would have some features such as game statistics (average completion times, number of hints used, number of error checks, etc). I’d also like to be able to sort games by completion time so that I could try to beat my old times on harder games.
