Killer Sudoku Calculator is a small set of free tools for people who solve killer sudoku, whether it comes from a newspaper, a puzzle book or an app.
What it does
- The calculator lists every combination for a cage, shows the digits that must and can't be in it, and works through several cages in one row, column or box with the 45 rule.
- The combinations chart shows all 502 cage combinations on one page, ready to print.
- The solver takes a whole grid and gives you one step at a time, with the reason, or the full solution.
How it works
Everything runs in your browser. The numbers you enter are not sent anywhere, and the solver saves your grid only on your own device. There is no sign-up.
The site has no connection with any newspaper, publisher or puzzle app. Killer sudoku is used here as the general name of the puzzle.
