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!

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
- Autosave -- switch puzzles at any time without losing your work
- Multi-square note entry -- a huge timesaver
- Combination lists -- can be rearranged on the screen for easy comparison
- Puzzle gallery -- scroll through puzzles and see your progress instantly
- Quick sum button -- add all selected sum labels instantly
- Quick combination list button -- list 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 feature -- automatically remove eliminated notes when you enter an answer
- Two color schemes -- a neutral newspaper color scheme and a rainbow color scheme
- 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.

What's New in Version 3.6

Bug fixes for auto note.

New in the last version, in case you missed it:
- Cross out combinations from a combination list: just tap to cross out, and tap again to undo
- New auto note feature: automatically removes eliminated notes when you enter an answer
- No timer option: hides the timer and removes your finish times from the puzzle list
- Bonus #160 no longer crashes. Thanks to the users who emailed about this!

I am really excited about the new features in this version! In particular, crossing off combinations from a list is extremely handy. I find the auto note feature a bit TOO useful sometimes, but for the harder puzzles it's a great way to remove some of the busywork so you can focus on the more complicated strategy. The new auto note and timer options can be found by pressing the button with a light bulb on it.

I hope you guys enjoy the update, and thanks again to everyone who sent feedback! Happy Puzzling --Sarah

Customer Reviews

Greater than before, but still with suggested improvements

Thank you for letting me turn off/hide timer! I'd still like to see: 1. An option to keep entered numbers in ascending order. 2. A way to get the most difficult puzzles without having to buy the pack with all levels. I have no use for Easy and Medium puzzles. 3. A way to check for errors all at once in the whole puzzle, instead of just getting error feedback when I try to enter a wrong number from the top or left number pad.

Great design, fun game

Love the update! Being able to cross out combinations saves me reaching for the back of an envelope to take my own notes on the harder impossible games. Auto notes make it a somewhat different game; I think I'll like trading off to play some games with them on and some with them off.

The dual keypads are awesome, I wish more apps would use them. The layout and controls are easy to see and to use. Nice tools, too.

A different take on Sudoku

I am enjoying Sudoku Killer. It is different from my previous apps in that it doesn't provide any filled in squares but provides sums of various blocks. It is then the challenge to complete the puzzle so that the numbers total the provided sums plus follow sudoku rules concerning no duplicate numbers in rows, columns or squares. Quite interesting and quite challenging.
