Killer Sudoku is a variation of Sudoku that adds an extra challenge by using cages to restrict the placement of numbers.
The basic rules of Killer Sudoku are the same as standard Sudoku:
Each row, column, and 3x3 block must contain the numbers 1-9 exactly once.
The new rule in Killer Sudoku is that there are cages in the puzzle. Each cage has a number in its corner that tells you the sum of the numbers in that cage.

The new rule in Killer Sudoku is that there are cages in the puzzle. Each cage has a number in its corner that tells you the sum of the numbers in that cage.
For example, if a cage has the number 15 in its corner, then the numbers in that cage must add up to 15.
No number appears more than once in a cage.
To solve a Killer Sudoku puzzle, you need to fill in the grid so that the numbers in each row, column, and 3x3 block add up to the correct number, and the numbers in each cage add up to the number in the cage's corner.
Here are the Killer Sudoku rules in detail:
The numbers 1-9 must appear exactly once in each row, column, and 3x3 block.
The numbers in each cage must add up to the number in the cage's corner.

The numbers in the cages can be used to eliminate possible numbers in other cells.
The numbers in the cages can also be used to create patterns that can help you solve the puzzle.
Killer Sudoku can be a challenging puzzle, but it can also be a lot of fun. By adding this extra layer of complexity, Killer Sudoku forces you to think more strategically about the placement of numbers.

Here are some tips for solving Killer Sudoku puzzles:
Look for patterns and eliminate any numbers that cannot be in a particular square.
Use the cage numbers to your advantage. If you know that the numbers in a cage must add up to a certain number, you can rule out any other numbers that do not fit that pattern.
Be patient and persistent. Killer Sudoku puzzles can be challenging, but they are also very rewarding.
