## Killer Sudoku! Description
Even better than killer sudoku on paper!

Killer sudoku is a popular variation on classic sudoku puzzles. To complete a puzzle you must fill the board with numbers that obey traditional sudoku rules AND make each outlined region sum to a specific value. The grid begins blank, but these rules give you all the information you need to solve the puzzle!

Solving a killer sudoku puzzle requires a lot of notes, so we worked hard to make the note entry features in this app perfect. A dedicated note keypad and the ability to select multiple squares makes entering notes fast. You can even make combination lists that float above the puzzle and can be rearranged on the screen! Cross out combinations from your lists as you rule them out.

Our interface is so good, you may prefer it to doing puzzles on paper.

Features: 
- Dual keypads -- no tedious toggling between note and answer mode 
- Multi-square note entry -- a huge timesaver 
- Handy combination lists -- can be rearranged on the screen for easy comparison
- Quick sum button -- add all selected sum labels instantly 
- Quick combination list button -- list all combinations fast by dragging over the desired region
- Built-in mini calculator -- do even long sums easily
- Undo & redo buttons -- step back through your changes to fix a mistake
- Mistake highlighting option -- don't let mistyped entries from set you back
- Auto note option -- automatically remove trivially eliminated notes when you enter an answer
- Two color schemes -- a neutral newspaper color scheme and a rainbow color scheme
- Puzzle gallery -- scroll through puzzles and see your progress instantly
- Comes with 10 free puzzles for testing, and over 3,000 puzzles available for purchase

We made this app free so that you can test it without having to buy anything. It comes with ten free killer sudoku puzzles--two puzzles in each of the five levels. There are also more than three thousand puzzles available to purchase, but the ten free puzzles might just keep you busy for a long time :)

All our killer sudoku puzzles have a unique solution.

## Killer Sudoku! Reviews in United Kingdom

### ***** "Best Killer Sudoku App"
I’ve really enjoyed this game. Great user interface. Just reached Impossible #200. No more games to play. I’m so sad! Thanks for an enjoyable experience.
-- Wynjer, 2025-09-20

### **--- "Good game absorbing"
Enjoy playing
-- I refuse todothis., 2025-08-31

### ***** "Outstanding app"
Really easy to use, and has all the tools to solve puzzles. Really well developed, and extra puzzles very cheap to purchase
-- Up the villa, 2025-08-29

### ***** "Relaxing"
I find these puzzles a good way to relax.  I think I must have been playing over 20years.  As soon as I’ve finished them all I delete the app then restart it, that way you can do the puzzles over and over again!  There’s so many of them you can never remember.  But I am getting much quicker at finishing them.  I’m very immobile with poor sight so can only do them on iPad now.😊⭐️
-- Bramble hedge, 2025-05-09

### ***** "Killer Sudoku"
This app is pure genius. I didn't think it was possible to design killer sudoku on screen. This is far better than the paper version. Well done and thanks. Sam
-- Music fest, 2025-03-26

### **--- "In-App Purchases cannot be re-loaded"
No way to reload in-app purchases if the app gets unloaded.
-- Bagpuss1234567890., 2025-02-04

### ***** "Judy"
Simply the best killer sudoku I have tried. I love it.
-- jesjebby, 2025-01-09

### ***-- "Great if it wasn’t for the cost"
The game design is excellent, very conveniently laid out with useful features like the calculator, and the optional colours for clearer differentiation between groups. Wonderful that both pencil and pen are options at the same time etc. I like how you can put the numbers in in any order eg.2938 to remember the combinations for 11. However you only get 8 free puzzles, at first I thought it was a daily thing where you’d get new ones each day but no. I’ve done them now so I’m deleting the app because I’m not willing to pay for more. If you do want to pay then the app is good, otherwise it won’t last over a week
-- D0nna N0ble, 2024-10-13

### ***** "The best Killer Sudoku"
Having played all the extra hard, impossible & bonus puzzles and packs and wishing there were yet more to buy (?) I can affirm this is the best, most playable killer sudoku app ever. Loved it.
-- MaresmeWeatherPerson, 2024-09-22

### ***** "A1"
Easily the best killer sudoku app available
-- key west padder, 2024-06-04
