Big Sudoku Book for Adults: 1000+ Medium to Hard Puzzles

Brilliant book. My other half said it keeps me quiet!! LOL

Good size and clearly set. Great value for money and came quickly. Bought as a gift but will be buying one for me.

It's alright. The puzzles are fine but not the hardest out there. It's the paper quality which irks me somewhat. It's not really good, quite thin and rough in my opinion which makes the experience of doing the puzzles a bit unpleasant. Otherwise okay.
