100 Hard Killer Sudoku Puzzles

Just like classic Sudoku, Killer Sudoku(also called killer su doku, sumdoku, sum doku, sumoku, addoku, or samunamupure)is a number placing puzzle game based on a grid with 9x9 cells. The object of the game is to place number1 to 9 in the empty cells so that each row, each column, and 3x3 box contains the same number only once. Besides, the sum of all numbers in a cage must match the small number printed in the corner, and the filled-in digits must be different.

In this pocket-size puzzle book, we've included 100 really challenging puzzles.

With the unique matte finish book cover, this book can be a great gift for family members, friends, and co-workers, especially those who love playing Sudoku and want to try a different and difficultSudoku style.
