Questions

Is it really free? Yes. Keep the small "Daily sudoku by Kodiak Sudoku" link under the puzzle; that is all we ask.

Does it work on WordPress, Squarespace or Wix? Yes. Add an HTML or "Embed code" block and paste the snippet.

Can I change the size? Edit the height in the snippet. 720 fits the board and number pad on most screens.
