About Large Sudoku and the large print design principles behind the senior-friendly Sudoku site.
Why Large Sudoku Exists
Large Sudoku is part of the Large series: large print puzzle and game sites designed for older players who want clear screens, calm pacing, and no forced account flow.
Big numbers, tap-to-fill controls, pencil marks that remain readable, and no countdown pressure.
