One Per Page
One Puzzle Per Page Large Print Sudoku
One puzzle per page is often the clearest print format for older adults. It gives the grid more room and avoids squeezing notes into a crowded sheet.

Large Sudoku's print mode removes game controls from the page, which keeps attention on the puzzle.
