Sudoku Large and Web Sudoku

The first choice is where you want to play. Sudoku Large is built for iPhone. Web Sudoku provides a puzzle you can open in a web browser.

This comparison was checked on September 18, 2026. Sudoku Large is testing on TestFlight for iPhone.

What Web Sudoku offers

The official Web Sudoku puzzle page provides browser play, difficulty choices labeled Easy, Medium, Hard, and Evil, and an option for pencil marks. It also links to puzzle selection and other formats.

A browser puzzle is useful when you want to start on a computer or move between devices without first choosing a dedicated iPhone app. The page you see and its fit on your screen are worth checking directly.

Why choose an iPhone-focused app

Sudoku Large’s design starts with the phone screen and people who prefer larger type. We consider the digits, box boundaries, and number controls as one reading and input experience.

A browser can enlarge an entire page. An app can make more specific layout choices for a phone. Neither approach guarantees comfort by itself, so compare what is actually visible and usable at your preferred size.

Compare the space you have

On a computer, you may have room for a much larger board. On an iPhone, check whether the full grid, the number controls, and any notes remain visible together. Try enlarging the page and see whether you need to move it from side to side.

If you prefer to solve away from a screen, our large print practice sheet is another format to try. For your phone, see the Sudoku Large design.
