The Times Killer Su Doku Book 12: 150 lethal Su Doku puzzles (The Times Su Doku)

"The Times" Killer SuDoku are my favourites. The easy puzzles are a bit too easy, but the tough/difficult ones are just about right for spending half an hour more but not the several hours that some of the seriously baffling brands take. Even better are the "Ultimate Killer" Times books, which don't have the easy puzzles to "waste" time on, but which go straight into the challenging grids. Very enjoyable

My mum is a whizz at these she never ceases to amazes me!

Great puzzles, with clearly defined grids / cages; although perhaps not as difficult as they suggest, seeing as I normally do them in about 30% of the time they reckon it should take. Also a little pricey in comparison to others on the market

As expected

This was bought as a present and the recipient was delighted with it.

price was inc from that advertised

Could not work this out. Will stick to normal ones in future.

Challenging puzzles, well printed and a real test of logic.
