How the daily puzzle works

• The puzzle changes at midnight in your own time zone.
• Everyone gets the same puzzle on the same day, so you can compare notes with friends.
• The first time you finish it each day counts, and it shows up in your statistics.
• Hints, notes and both ways of entering digits work as in any other game.

Prefer to pick a level?

You can also choose a difficulty:

• Easy: mostly obvious moves
• Medium: scan rows, columns and boxes
• Hard: notes and simple eliminations
• Very Hard: pairs, triples and x-wings
• Expert: wings, chains and rectangles
