Times Killer Su Doku Book 16: 200 Lethal Su Doku Puzzles

The Times Killers are exceptionally hard and super fun to solve. Recommended!

How the 200 puzzles can be "lethal" when a good number are quoted as 22 minutes or less is beyond me. From past experience of the Sunday Times books I expect some of them to be fairly challenging, but nowhere near the German books produced by Stephan Heine. If you want some serious puzzles his hardcore book 4 is pretty good, although I found most of them do-able.

Bought this for my daughter for her birthday. She had struggled to find a book that only had Killer Sudoku puzzles in it, and where the puzzles were difficult enough.She was very pleased with this book. There are lots of puzzles, there are different levels of difficulty, with plenty of puzzles difficult enough so that they take a reasonable amount of time to complete.

You'll need to allow alot of time to get through these but they deliver on being as difficult as they claim to be.

Didn't notice "lethal " in the title! Certainly challenging.

.....good to keep your mind active, especially under today's COVID like circumstances!
