A little time for yourself

Sudoku

Nine rows, nine columns, one quiet challenge. Fill every row, column and 3 × 3 box with the numbers 1–9, without repeats.

Choose your difficulty, take on a shared daily puzzle or revisit an earlier date. Your entries and notes stay in your browser, ready when you return to the same board.

Find your next break

Explore five difficulty levels on the classic 9 × 9 grid, from Very easy to Very hard. New to the game? The illustrated Sudoku guide walks through rules and logical steps.

Pre-launch dates belong to a backfilled archive collection, not puzzles published on those past dates. Only available catalogue entries are listed. A date is a link to a board, not a new copy of your progress.
