### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Disappointingly easy
  

*by S***L on Reviewed in the United States 🇺🇸 on December 20, 2022*

For a book labeled "super tough", these are not. If you're looking for something that about matches the 3-star puzzles in your local paper, then this is for you.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Okay Puzzles
  

*by C***N on Reviewed in the United States 🇺🇸 on March 22, 2014*

I bought this book after going through the "brown belt" book. I had hoped these puzzles might be a bit harder, but its pretty hard to tell any supposed difference in difficulty between the brown and black.My local newspaper offers sudoku puzzles that are rated on a scale of 1 (easy) to 4 (hardest). I usually have to mark up the "3" puzzles with notes. I always have to mark up the "4" puzzles to solve them, and even with the mark-ups, I don't always succeed in solving them.These puzzles I'd rate between the "2" and "3" level. I solved them all without needing to make any notes. They're enjoyable, but only a few were more than a few minutes' work. For me, that's acceptable: something to help me wake up in the morning, or to keep me occupied when I have a little time to spare. But if you're looking for level "4" puzzles, this is NOT the book you want. I rated the book four stars because I did enjoy the puzzles, but the book does not live up to its name.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

Accurate title. Harder than brown belt but still solvable with some less linear thinking.
