Are you looking for a challenging and stimulating puzzle to test your mental agility? Then you’ve come to the right place! Killer Sudoku is a unique and challenging variant of Sudoku that combines the classic rules of Sudoku with an additional layer of complexity. It’s a great way to sharpen your mind and improve your problem-solving skills.

What is Killer Sudoku?

Killer Sudoku is a logic-based puzzle in which you must fill in a grid with numbers so that each row, column, and 3×3 subgrid contains all of the numbers from 1 to 9. However, there’s an extra twist: the grid is also divided into cages, and each cage has a number in its corner that represents the sum of the numbers in that cage.

How to Solve Killer Sudoku

Solving Killer Sudoku can be challenging, but it’s also very rewarding. Here are a few tips to help you get started:

  1. Start with the easy puzzles and work your way up to the more difficult ones.
  2. Try to fill in the numbers in the usual Sudoku way, making sure that each row and column contains all of the numbers from 1 to 9.
  3. Pay attention to the cages and the numbers in their corners. The numbers in the cages should add up to the numbers in the corners.
  4. Use logical deductions to eliminate possible numbers from the grid.
  5. Don’t be afraid to backtrack if you get stuck.
