Killer Sudoku, also known as Sum Sudoku, blends Sudoku with Kakuro. Like usual Sudoku, each row, column, and 3x3 box must have the numbers 1 to 9 once. The unique part is the shaded areas with a clue number in the corner; the numbers inside these areas must add up to that clue. Killer Sudoku is ideal for puzzle enthusiasts, math lovers, students, brain training advocates, and casual gamers seeking a challenging and mentally stimulating activity.
How To Play Killer Sudoku
The aim is to complete every empty square in each row, column, and 3x3 box with numbers 1 to 9, making sure each number appears just once. Adding a twist, there are 'cages' with a distinct background color and a number in the upper left. Each number in these cages must be unique, and their sum must match the clue given in the cage's top-left corner. Each Sudoku puzzle has one correct solution. This blend of Sudoku and arithmetic adds an intriguing twist, making every puzzle a unique and rewarding challenge.
