Welcome to the Puzzle Doctor’s Killer Sudoku Logic Puzzles – Hard Level Book 5
Killer Sudoku is a fun variant of the popular traditional Sudoku puzzle! This logic puzzle combines the classic structure of Sudoku with a bit of number-crunching. Like standard Sudoku, the objective of each puzzle is to fill in the grid with digits 1 through 9 in such a way that no column, row, or grid block contains the same number twice.
Also known as Sum Sudoku, Killer Sudoku distinguishes itself with sub-regions or ‘cages’ where the numbers within each cage must add up to the sum displayed and no numbers may repeat within a cage. This game offers a rich problem-solving workout beyond ordinary Sudoku.
