About Jigsaw Sudoku (PuzzleMadness)

Jigsaw Sudoku keeps the rows and columns of a normal sudoku but swaps the nine 3x3 boxes for nine regions of any shape, each still nine squares in size. The usual techniques carry over, but the odd shapes make some deductions harder to see, because a region can stretch across three or four rows.

The daily page opens today's puzzle on its own, and its title carries the date (on 3 October 2026 it read "Daily Medium Jigsaw Sudoku Puzzle for Saturday 3rd October 2026 (Medium)"). There is a separate dated puzzle for each difficulty: Easy, Medium, Hard, Tough and Mixed. Past days stay in the archive, so a missed puzzle can be played later, and there is a print version and an image download of the grid. PuzzleMadness does not publish solutions: the site tells you when you have finished a grid correctly or made a mistake. Each completed puzzle adds to your total on the Jigsaw Sudoku monthly and all-time leaderboards, where only your best score on any one puzzle counts.

Solve it as you would a normal sudoku and look carefully at where each region reaches. A region that dips into a row or column often forces a digit out of the rest of that line. Start with Easy if the shapes feel strange; the Tough grids give far fewer starting digits.

PuzzleMadness is a British puzzle site with dozens of daily puzzle types in the browser, from many sudoku variants to logic grids such as Nurikabe, Hashi and Slitherlink. It is free to play and carries ads. A free account keeps track of the puzzles you have finished and puts your name on the leaderboards, and the badges next to usernames mark how many puzzles a player has completed.

How to play Jigsaw Sudoku (PuzzleMadness)

1. Open the day's Jigsaw Sudoku page and pick Easy, Medium, Hard, Tough or Mixed.
2. Select a square and type or tap a digit; use pencil marks for candidates.
3. Make every row, every column and every outlined region contain 1 to 9 exactly once.
4. Fill the last square correctly and the site records your score.

Tips

• Trace the outline of each region before you start; the bends are where the deductions hide.
• Count how many squares of a region sit in one row: if they must hold a digit, it is ruled out of the rest of that row.
• Pencil marks pay off sooner here than in a classic sudoku.
