Box Brain Sudoku

Accessibility

Sudoku you can play by ear, by touch or at any size.

Box Brain Sudoku works with VoiceOver from the first screen to the last digit. There is help for low vision, colour blindness, hearing loss and motion sensitivity too, and every bit of it is free.

Quick setup

Set the app up for how you see and hear it. You can change any of this later in Settings.

I am colour blindAdds shapes to the board, so nothing depends on telling colours apart.

Offered on the very first screen of the app, on Home, and in Settings › Accessibility.

VoiceOver

Hear the board

With VoiceOver, every cell says where it is, what it holds and the clues around it, like a Killer cage's total and how much it still needs. Swipe up or down on a cell for its actions: read its row, column or box, or enter, note and erase a digit, without seeing the board.

Try it here. Tap a cell or move with the arrow keys, then read a row, column or box. The words are the ones the app speaks.

Hearing and seeing the board

Settings for every way you play

Turn on just what helps. Each one works on its own or with the others.

Read aloud

No screen reader needed: the app speaks the selected cell and each move with your phone's voice. Hold a cell to hear its row, column and box.

Large digits

Bigger numbers in the grid

Larger text and bold text

The app follows the text size, bold text and contrast set on your phone.

High Contrast skin

Black on white with bold lines and big digits. Free for everyone.

Shapes for colour blindness

A ring on the selected cell, dashed rings on hint cells and a symbol on each colour mark

Flash for sounds

The screen edge flashes on a mistake and when you finish a row, column, box or puzzle, with or without sound

Haptics

A light tap on each entry, a firmer one on a mistake, a double tap when you finish a row, column or box

Sound effects

Soft sounds for entries, mistakes and solves. Quiet when your phone is on silent.

Reduce Motion

Turn on Reduce Motion on your iPhone or iPad and the board stops sliding and bouncing. Everything still works the same.

Colour blindness

Shapes, not just colours

Nothing in the game depends on telling colours apart. Turn on shapes and the selected cell gets a ring, hint cells get dashed rings, and each colour mark carries its own symbol.

  • A ring on the selected cell, not only a tint.
  • Dashed rings show where a hint is pointing.
  • A symbol on each colour mark, so marks read in any light.
Braille

Braille sheets, free for everyone

Make puzzles as a .brf file for a braille embosser or a braille display, or a PDF of raised dots for swell paper. Classic, Diagonal, Hyper and Anti-Knight, from easy to hard, each with its answer. In the app, or right here on the website.

Questions

Do I need Box Brain Pro for any of this?

No. Every accessibility feature, Read aloud and braille sheets are in the free version, and always will be.

Which modes work with VoiceOver?

All twelve. Each cell reads its own clues too: a Killer cage's total, arrows, thermometers, dots, greater-than signs, even and odd cells, and Sandwich sums.

Should I use Read aloud or VoiceOver?

Either. Read aloud is for when you want the board spoken but not the whole phone. When VoiceOver is on, Read aloud stays quiet so the two never talk over each other.

Where are the settings?

On the first screen when you open the app, on Home, and any time in Settings › Accessibility.

Is this website accessible too?

We build it to work with a keyboard and a screen reader, at any text size and with Reduce Motion. If anything gets in your way, please tell us.

Tell us what would help

Accessibility is never finished. If something is hard to use, or a feature would make the game better for you, we want to hear it.
