The Times Big Book of Ultimate Killer Su Doku book 2: 360 of the deadliest Su Doku puzzles Paperback – January 1, 2023

Over the past decade, I've repeatedly purchased every ultimate killer sudoku book published by The Times. Having solved more than 10,000 UKS puzzles to date, I can attest that this is the first-ever book published by The Times (or anyone else) that requires superior skill. Beginners won't want to buy this book. Several puzzles in the Big Book 2 have taken me more than thirty minutes to solve, rather than the typical 8-15 minutes utilized to solve a two-hour puzzle.My only complaint is that there is no cage reference section. Apparently the authors figured that anyone working at this level has most of the cage reference memorized anyway. Kudos to The Times for putting out a truly killer book.

Typical Times Sudoku book with challenging puzzles.

C’è un errore nelle istruzioni a pagina viii -27 in quattro gabbie NON contiene sempre 9+8 (vede puzzle numero 6 per esempio)

Die "The Times" Bücher mit Killer-Sudoku sind erstklassig. Wer schwere Sudokus liebt, der findet heir das Richtige.

The Times are definitely the best series of Killer Sudoku books. Great value for money. Endless hours of fun.

I love killer Sudoku and the single books have a grid of combinations. Beware this book doesn't. I'll have to tear out of my previous book.
