What to check before choosing an ad-free app
- Which ads are removed? Check whether an offer covers banners, between-game interruptions, and optional videos used to unlock hints.
- What is included? Free download, free puzzles, and access to every feature are different promises. Read the purchase details for archives, hints, and assistance settings.
- Does it suit your solving style? Try number entry, notes, undo, and the difficulty before committing to a paid option.
- Do you need offline access? Check the app's description and try opening a puzzle without a connection before relying on it while travelling.
Want Sudoku without a screen?
Our weekly PDF packs include seven puzzles and their solutions, with a choice of difficulty and A4 or US Letter paper. Download directly; joining the email list is optional. For copying a puzzle or making notes, use a blank Sudoku grid.
