6x6 Easy Jigsaw Sudoku Puzzles

About Jigsaw (Irregular) Sudoku Puzzles

Jigsaw Sudoku, also called Irregular Sudoku, is a different type of Sudoku puzzle. It follows the usual Sudoku rules but has a twist: instead of the regular square boxes, it uses areas with unusual shapes, like puzzle pieces. These are called "cages" or "jigsaw pieces." These uneven shapes can look different and don't have to be perfect squares.

Rules / How to Play

• Row Rule: Each row must contain all numbers from 1 to 6, without repetition.
• Column Rule: Each column must contain all numbers from 1 to 6, without repetition.
• Irregular Region Rule: Each irregularly shaped region must also contain all numbers from 1 to 6, without repetition.
• Prefilled Numbers: Some cells are pre-filled with numbers. These clues help guide the solver to the unique solution.

Solving Tips and Techniques:

Solving Jigsaw Sudoku requires a combination of classic Sudoku techniques and some additional strategies to account for the irregular shapes.

• Start with the Simplest Regions: Start with the areas that have the fewest clues. This makes it easier to find possible answers.
• Unique Numbers: Find the numbers that are missing in each row, column, or section, and fill them in, making sure no number repeats in any row, column, or section.
• Single Candidate (Naked Singles): If a cell can only have one number because of the rules, write that number in the cell.
• Single Position (Hidden Singles): If a number can only fit in one spot in a row, column, or box, put it in that spot.
• Use Pencil Marks: Use pencil marks to note down possible numbers for each box.
