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.

Excellent

Having fun with this, altho I think we are asked to rate before we really get an idea. I only played 6 games and was either asked to rate now or no thanks. Good game so far. Using all the available help, so I need to stretch myself a bit more once I get the hang of it and turn off the shading, and then the error indicator. You can certainly ease your way in, and lots of valuable hints and tips. I have no doubt I will purchase upgrades soon. Great game to learn new games with. Well thought out. I wrote this review several weeks ago and it doesn't seem to submit. Now I have installed the update and it is stuck on pause, can't use the game at all. Not happy but the game is fantastic. Hope it can be sorted ASAP

Best killer sudoku app.

I have loved using this app for years now. However Since downloading the app again for a new iPad every game is incorrect. Have tried buying the mega packs again but asks if we want to get free and won’t allow me to buy. My app is now virtually useless. Desperate to get it fixed. Looks like your last bug fix has caused this problem. I tried emailing you re this problem but has been ignored. Please check it out for yourselves.

Good app, shame about the price

The app is really well designed. Having a second keypad for pencilled in numbers is genius. I wish the draft numbers would be arranged in a grid so that the same digits were in the same positions. I haven’t gone beyond the 3rd level of difficulty - the puzzles are really hard. Having said that, I think the puzzle packs are too expensive. Not sure I’d purchase a second lot.
