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.

I have worked on most Killer Sudoku puzzle books I can find, and this has been so far the most interesting and challenging one. One major problem for me is that the numbers printed are so small and light that I must use reading glasses to work on them! I have found only one mis-print(?) of numbers, compared to finding several errors in other Sudoku books. First three levels are okay. When it gets to the advanced levels, this book is too chanllenging for beginners and/or casual players. It is a good gift only for serious Killer Sudoku lovers.
