Challenge yourself with number puzzles
The latest volume in the hugely popular Killer Su Doku series from The Times, featuring the highest-quality puzzles with an extra element of arithmetic.
These puzzles will test your skills to the limit, adding the challenge of arithmetic and taking Su Doku to a new and even deadlier level of difficulty.
The puzzles use the same 9x9 grid as Su Doku but with an added mathematical challenge. The aim is not only to complete every row, column and cube so that it contains the numbers 1-9, it is also necessary to ensure that the outlined cubes add up to the same number as well.
With 200 new Moderate, Tricky, Tough and Deadly Killer Su Doku puzzles, there is no chance to ease yourself in with simple puzzles. These puzzles are for those who like to live dangerously and push beyond their mental comfort zone.

Durable and loved by my dog.
Color: Red - Bacon
I recently bought this toy for my German Shepherd and Belgian Malinois mix, and I can't express enough how much she adores it. The durability of the material is impressive; it withstands her enthusiastic chewing without showing any signs of wear and tear. Its size is perfect for her to carry around with ease, and it keeps her thoroughly entertained for hours.
I've noticed that there’s no color transfer or degradation from her vigorous play, which gives me peace of mind. I can let her enjoy it without constant supervision, as I trust that she won't be able to chew off any little pieces that could pose a choking hazard. All in all, it's an incredible value for the quality, and I’ll definitely be purchasing another one for her in the near future.

Great, easy to chew toy!
Color: Orange - Maple Wood
Nice durable chew toy. My English Bulldog loves chewing the ends as well as the middle and the design is easy for him to hold with his paws as he chews

Great product
Color: Multicolor, Color: Multicolor
I have three aggressive, chewing dogs that absolutely love these bones. I've had them for a couple of months and they have yet to break them or damage them. Lots of chewing left.

Great for aggressive chewers!! My grand-dog loves it. It is slightly heavy, perfect for him. It definitely cleans his teeth. He plays with it all the time.
