What it helps with

Readable grid

Larger numbers and cleaner spacing make the board easier to parse at a glance.

Less strain

The interface stays quiet so the puzzle is the focus instead of the chrome around it.

Easier input

Bigger targets reduce the precision the game demands from the player.

Why this app exists

Most Sudoku apps are built as if everyone sees and taps the same way.

People looking for large-print brain games for seniors are usually solving a real accessibility problem, not just looking for another way to pass time. Small grids, subtle contrast, and cramped controls turn a relaxing puzzle into unnecessary strain.

DokuDoku started from the idea that readability should change the game itself. Stronger contrast, larger numbers, and more generous touch targets all make a difference before you add a single extra feature.

The result is a calmer Sudoku app for players who are usually asked to adapt to a visual design that was never made with them in mind.
