You can play killer sudoku online, right here! Tap on a cell to move the cursor to that cell. Tap on the keyboard that pops up to enter a value into the cell. If you are not sure of a value, you can enter multiple values in a cell. If you enter a value in a cell that is already there, it will be removed. If you press the shift key, any values entered overwrite all the others in that cell.

Use the >> and << keys to move to other keyboards.

If you have cookies enabled, you can save your current solution and come back to it later. Even if you don't explicitly save your solution, your work is autosaved. If you accidentally leave the page (e.g., you press backspace), and return before you exit the browser, you won't lose any work.

If you want some help generating the possible ways to create a sum, use the sum calculator button, which will pop up a window to help.

Good Luck!

If you have suggestions, or iphone usability issues, please email us. Thank you.
