What is Pazuju?
Pazuju takes the rules of Sudoku and adds one twist: the grid isn't handed to you whole. Every puzzle starts as a set of irregularly shaped pieces. A few are already on the board. You drag and rotate the rest into place until they cover the grid completely, without overlapping. Then you fill in the numbers, so that each number appears once in every row, once in every column, and once inside every piece, whatever its shape.
That first assembly stage changes the solve. You're working out the board's layout before you can start on the numbers, and the shape of each piece becomes part of the logic.
Three puzzles, every day
Each day brings three new puzzles in three board sizes, named after the creatures on their cards:
- Grasshopper, a 6×6 board you can finish in a few minutes
- Snake, an 8×8 board for a short sitting
- Dragon, a 10×10 board for the full challenge
Difficulty doesn't depend on size. Each puzzle is rated Beginner, Intermediate, Advanced, or Expert by how many solving techniques it takes, and the harder puzzle moves between sizes from day to day, so you never know which board will be the toughest.
Past puzzles stay playable through the date picker on the Play page, so you can catch up on days you missed. Pazuju is free to play and needs no sign-up. It saves your progress, and you can add a nickname to post your solve times on each puzzle's leaderboard and build a daily streak.
From book to daily puzzle
Pazuju started on paper. Its creator, Jonathan Tillger, first published the puzzle in the book Pazuju: The Evolution of the Number Game Is Here. This site brings the same puzzle online as a free daily game. If you'd rather solve with a pencil, the book is on the Books page.
