Accessible-first Sudoku

Sudoku should challenge your brain, not your eyesight.

DokuDoku is a large-print Sudoku app with high contrast, a zoomed entry view, and clear controls for lower-strain play on iPhone and iPad. Built for players who want a clearer puzzle interface, including seniors and people with low vision.

Everything in one place

A lot of puzzle apps quietly assume everyone sees the same screen.

Large-print puzzle design is not cosmetic. Small grids, subtle contrast, and cramped controls can turn a relaxing puzzle into unnecessary strain.

Make the whole grid readable

Large, high-contrast numbers and clearly separated sectors keep the full puzzle understandable at a glance.

Zoom in before entering a number

Open any 3×3 section for larger cells, notes, and a roomier number pad that asks for less precision.

Adjust the experience to fit

Large print, dark mode, haptics, daily reminders, and eight languages are available from one settings screen.
