Are you ready to put your logical thinking skills to the test? Look no further than 'The Times Ultimate Killer Su Doku' book, a collection of deadly-level puzzles that will challenge even the most seasoned puzzle enthusiasts. Unlike other books that ease you in with easy and tough puzzles, this one is completely deadly, offering 100 puzzles that are designed to push your mental limits.

The puzzles use the same 9x9 grid as traditional Sudoku, but add an extra layer of mathematical complexity. The aim is to place the numbers from 1-9 once in each region of the puzzle, ensuring that every row, column, and cube contains the digits 1-9 without repeating any number. But that's not all - the outlined cubes must also add up to the same number, making it a true brain-twister.

The book is divided into eight different puzzles per booklet, with each page containing a single puzzle. The booklets are ordered by ascending difficulty, so you can start with the easier ones and work your way up to the most challenging. But be warned - once you get to the higher levels, it's not for the faint of heart.
