How To Play Sudoku

To take notes, click the small numbers inside a cell when it is selected. Alternatively, click the notes button in the lower right corner, and then click the numbers in the button bar.

Keyboard Shortcuts

Press the arrow keys to move the cursor around. Press a number key from 1 through 9 to set a number. Press backspace to clear a number. Press N to switch to note-taking mode, or press Shift-1 through Shift-9 to set notes without switching modes.
