In our Crack The Safe books, pure reasoning is the name of the game. The format is such that the clues are easy to digest and, in a sense, obvious. There's no need to translate verbal statements into logical facts, as is the case in our Grids For Kids books. Instead, all of the solver's effort is focused on the reasoning process. So put on your Sherlock Holmes hat and remember: this time, you're not nabbing the safe cracker, you ARE the safe cracker!
This book consists of 30 puzzles, as well as detailed solution tutorials. Each puzzle involves finding the correct combination for a combination lock, given certain clues regarding the "closeness" of some incorrect guesses.
The puzzles progress in order from easiest to more difficult. All lock combinations in this Level 1 book contain three unique digits - no digits are repeated.
