Play Medium Jigsaw Sudoku Online

Medium Jigsaw Sudoku gives you a balanced irregular Sudoku challenge. The rules are familiar, but the non-square regions create new solving paths that make each puzzle feel different from classic Sudoku. Play free, no sign-up required.

How to Play Medium Jigsaw Sudoku

Fill the 9×9 grid with digits 1–9 so every row, column, and jigsaw-shaped region contains each digit exactly once. Medium puzzles usually have fewer immediate placements than Easy puzzles, so you need to combine more clues before each move.

  • Each row must contain digits 1–9 once
  • Each column must contain digits 1–9 once
  • Each irregular region must contain digits 1–9 once
  • Check region borders before placing a number
  • Use candidates when more than one number seems possible

What Makes Medium Jigsaw Sudoku Different?

Medium Jigsaw Sudoku is where irregular regions start to matter more. You will still find clear moves, but many placements require checking how a row, column, and region overlap. A number may be blocked not by a classic box, but by a curved or stretched jigsaw region that reaches into another part of the grid.

This level is ideal if Easy puzzles feel too quick, but you still want a smooth solve without the intensity of Hard or Expert difficulty.

Medium Jigsaw Sudoku Solving Strategies

Strategy 1: Scan One Number at a Time

Pick a digit and check where it can fit across several rows, columns, and regions. Irregular regions often create placements that are not obvious from the row alone.

Strategy 2: Compare Overlapping Areas

Look at how a jigsaw region overlaps with nearby rows and columns. If a digit can only go in one part of a region, that can block the same digit from nearby cells.

Strategy 3: Use Candidates in Crowded Regions

When a region has several empty cells, list the missing digits and remove any that already appear in the connected rows or columns. This usually reveals a safe placement.
