# A Ring of Cats and Dogs

We review the first of this year’s nominees for the Book of the Year

Daniel Griller is a teacher and puzzle enthusiast from the UK. A Ring of Cats and Dogs (and Other Curious Puzzles) (Amazon UK) is Daniel’s second puzzle book (his first was Elastic Numbers, released in 2017).

## Style

Like Elastic Numbers, the puzzles in A Ring of Cats and Dogs (and Other Curious Puzzles) are split into four sections—bronze, silver, gold, and diamond—by difficulty. If you’re a seasoned puzzle solver then you’ll find the bronze and many of the silver puzzles a little easy, but the gold and diamond sections contain some real gems that definitely make this book worth buying.

## Control

The first part of this book consists of the bronze, silver, gold and diamond sections, each containing 25 puzzles. The second section contains solutions to each puzzle. These solutions are clearly written and very detailed and provide a very useful lifeline if a puzzle has really stumped you.

## Damage

As you do more and more puzzles, it becomes increasingly hard to find new puzzles that you haven’t done before (or done very similar puzzles before). One of this book’s greatest strengths is that it contains new puzzles that are likely to make even the most experienced puzzlers think.

## Aggression

If you’re a puzzle fan, I strongly recommend this book (as well as Elastic Numbers if you don’t already have it). If you’re not a puzzle fan, then you may find that this book encourages you to become one.
