Large print Sudoku, made for tired eyes

Every Sudoku here is built around the board, not around the page. The numbers are drawn in Atkinson Hyperlegible, a typeface created by the Braille Institute so that look-alike characters are easy to tell apart. You can choose from three text sizes and from three colour themes: Morning edition, Evening edition and High contrast. The text and button colours are checked against the WCAG 2.2 AAA contrast level of 7 to 1 every time the site is built.

Buttons are at least 44 pixels square, and a tap that lands a little outside a square still chooses the nearest one. Nothing needs dragging, and Undo is always one press away.

A calm way to keep your mind busy

Sudoku asks you to hold a few possibilities in mind, rule some out, and commit when only one is left. Many people find that a pleasant kind of focus. Researchers have not settled whether puzzles protect against memory decline, so we will not promise that. We can say that a puzzle you enjoy is a good reason to sit down with a cup of tea, and that finishing one feels good.

There is no pressure here. The timer counts up rather than down, you can hide it with Zen Mode, and it pauses by itself if you step away.

How to play

Fill the grid so that every row, every column and every 3 by 3 box contains the numbers 1 to 9 exactly once. Tap a square, then tap a number on the number pad, or type the number on a keyboard. The arrow keys move around the board, Backspace clears a square, and Ctrl+Z undoes your last move. Hold Alt and press plus or minus to change the text size, and press Alt+T to change the theme.

If you are stuck, press Hint. The first press highlights a row, column or box where a move is waiting, and a second press fills the number in. Hints only count toward the stars you earn at the end: three stars for none, two for one or two, and one for three or more. The time you take never lowers your stars.

Two sizes, and some relatives

Besides the classic 9 by 9 grid there is a gentler 6 by 6 size. A free Classic Easy puzzle arrives every day, and members will be able to play both sizes at every level. If you enjoy Sudoku, try its relatives: Wordoku with letters, Calcudoku with cage totals, and Colorku with coloured shapes.

Saving and printing

Your progress is saved on your own device after every move, so you can close the page and come back to exactly where you were. The free daily puzzles need no account; members who sign in keep their progress on every device. To print a puzzle, press Ctrl+P (Cmd+P on a Mac): the buttons drop away and the grid prints in large black type.

Frequently asked questions

Is Senior Puzzles Daily free?
Partly. Every day there is a free Easy puzzle of six kinds (Sudoku, Wordoku, Calcudoku, Colorku, Crossword and Word Search), with the Cryptogram coming soon, with no account and nothing to pay. Membership is coming soon and will add the Medium and Hard levels, every theme and grid size, unlimited puzzles every day (always your own next unsolved one), and your scores and history on every device. There are no ads.
Do I need an account or an email address?
Not for the free daily puzzles: your progress is saved on your own device. Members will sign in with Google or with a six-digit code sent to their email address, so there is no password to remember, and their scores and history will follow them to any device.
Can I play without an internet connection?
The free Easy puzzle can be. Once you have visited the site, it keeps a supply of free puzzles on your device, so today’s free puzzle still opens if the connection drops. Puzzles you have not opened before need a connection.
How do I make the numbers bigger?
Use the Text size buttons at the top of any page and choose Medium, Large or, on a larger screen, Extra large. On a keyboard, hold Alt and press the plus key to step up, or the minus key to step down. You can also zoom the board itself with the Zoom In button.
What do Easy, Medium and Hard mean?
Easy is the level that is free every day. Easy puzzles can be finished by spotting the one square where a number fits, or the one number that fits a square. Medium uses the same ideas with fewer numbers given at the start. Hard needs a little more than those simple moves, and the Hint button is there when you want it. Members will be able to play all three levels.
What is the 6 by 6 size, and what are Wordoku, Calcudoku and Colorku?
Sudoku comes in a classic 9 by 9 grid and a gentler 6 by 6 grid, and the 6 by 6 size will be part of membership. Wordoku, Calcudoku and Colorku are relatives with their own pages. Wordoku uses letters instead of numbers. Calcudoku has no boxes: the grid is divided into cages, and the numbers in each cage must add up to the small total shown in its corner. Colorku uses bold coloured shapes. Each has a free 9 by 9 Easy puzzle every day.
