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.
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.
