Killer Sudoku Djape

This is a special, 10th anniversary edition of the first book with Killer Sudoku puzzles by Djape. Introduced by The Times, the British publisher who pioneered the sudoku craze, the "killer sudoku" poses a double challenge: the basic rules of sudoku still apply, but puzzles initially have no numbers showing. All that is known is the sum of the numbers inside irregular boxes, called cages, in which the classic 9 x 9 sudoku grid is subdivided. Killer Sudoku contains 101 of these brain-busters grouped into six levels of difficulty. The introduction explains the basic techniques needed to solve these new versions of the world's most popular number puzzle.----------------------------------------------------------addoku, sumdoku, samunamupure, fiendish killer sudoku, difficult killer sudoku, sudoku k, sudoku killer, hard killer sudoku, killer sudoku book, addoku book, sumdoku book, samunamupure book, difficult killer sudoku book, cool, thinker, brain, iq killer sudoku, insane killer sudoku, djape killer sudoku, djape, djape killer, djape insane
