I love logic puzzles but, like other reviewers, have struggled to find books of just logic puzzles in the shops.
This book was a real find - 200 really well written puzzles, plenty of space for working out and all the answers in the back. It starts out with relatively easy puzzles and then progresses onto trickier ones - I haven't been brave enough to tackle the ones at the back of the book yet as they look really hard!
Each puzzle is rated for difficulty (as a percentage of people who solved it successfully on the Puzzle Baron website - where there are even more puzzles for the true addicts!) and an average time to solve it given. I'm ashamed to say I'm currently performing below average but enjoying it thoroughly!
If you're new to logic puzzles there are lots of instructions at the front.
I'd whole-heartedly recommend this book and have already added Volume 2 to my wish list!
