Sudoku Large Print for Seniors

Sudoku Large Print is classic 9×9 sudoku made for comfortable reading: big numbers on a board as wide as your screen, large labelled buttons, and no clock or mistake limit pushing you along. It is a sudoku for seniors first, and pleasant for anyone who prefers a puzzle in large print.

Big numbers, easy to read
The digits fill most of each square, and you can make them bigger still: choose Normal, Large or Extra large text, and turn on high contrast for black-and-white lines. Numbers that were given are printed in bold ink, yours are written in pen blue, so you always know which is which. Every button has a word under its icon.

A new puzzle every day
Today's puzzle is a daily sudoku with the same grid on every phone, gentle at the start of the week and harder towards the weekend, like the puzzle page of a newspaper. Solve it each day to keep your streak going. Alongside it, play as many puzzles as you like at four levels, Easy, Medium, Hard and Expert, all open from the start.

Pencil notes, just like paper
Turn on Notes to jot small candidate numbers in a square. A number you place clears itself from the notes around it, and one tap fills in every note when you want a head start.

No pressure, ever
There is no timer on screen unless you switch it on, no limit on mistakes and no game over. Wrong numbers can be shown in red, or not at all. Undo as often as you like, and use hints without limit: a hint fixes a wrong number first, then fills the easiest square, so it teaches rather than just gives the answer away.

See how far you've come
Statistics show your daily streak and your best run, and for each level how many puzzles you solved, how many without hints, your best time and your average time.

Comfortable day and night
A warm paper look by day and a dark reading-lamp theme in the evening. Every move is saved as you play, so you can close this large print sudoku at any time and carry on exactly where you left off.

Easy to learn
A six-step How to play guide explains the rules and every button in plain words, written for seniors and first-time players alike. Open it from the home screen or in the middle of a game.

The app works offline and needs no account. It is free with ads: a banner at the bottom of the screen, and a full-screen ad only between puzzles, never while you are solving one. A one-time purchase removes all ads and can be restored on a new phone with the same Google account, or watch one short video for two hours without ads. Every level, hint and feature is free for everyone.

Available in English, German, French, Spanish and Dutch.
