Easy Windmill Sudoku Puzzles

About Windmill Sudoku Puzzles

Windmill Sudoku, also known as Kazaguruma Sudoku, is a type of Sudoku puzzle that looks like the regular version but has a special rule. It has a "windmill" pattern, which adds extra challenges to the puzzle. This pattern includes a central grid, like in regular Sudoku, but with additional rules that create a windmill shape. These extra rules make the puzzle more difficult, but the main idea is the same as regular Sudoku.

These windmills can be rotated, and the numbers in the cells must obey the standard Sudoku rules: each row, column, and windmill must contain the numbers 1 through 9 without repetition.

Basic Rules / How to Play

• Grid Structure: The puzzle consists of five 9x9 grids. These grids overlap in a unique pattern, resembling a windmill.
• Number Placement: Each grid must be filled with numbers from 1 to 9.
• No Repetition: Each row, column, and 3x3 subgrid must contain the digits from 1 to 9, with no repetition in any row, column, or subgrid.
• Windmill Pattern: The "windmill" is a pattern that starts from the center of a 3x3 block and spreads out in different shapes. These shapes can be diagonals, crosses, or other patterns that connect with specific rows, columns, or smaller blocks.

Solving Tips and Techniques:

To solve a Windmill Sudoku puzzle, you need to use methods from regular Sudoku along with special strategies for the unique rules of the windmill pattern. Here are some common techniques:

• Scanning: Look at the rows, columns, and smaller grids to figure out where the numbers should go.
• Elimination: Remove numbers that can't be correct from the empty cells by using the given digits and rules. This helps to limit the possible choices for each empty cell.
• Cross Hatching: Look at the rows and columns that cross a certain small grid and figuring out where numbers can or can't be placed.
• Focus on the Windmill Pattern: Look for the windmill shape in the grid. Pay attention to how it fits with the rows, columns, and smaller sections. This can help you figure out where certain numbers should or shouldn't be placed.

You can solve Windmill Sudoku puzzles easily by using regular Sudoku methods along with strategies designed specifically for the windmill pattern.
