By Tomas Klos This is a great book full of delicious calcudoku puzzles (also known as KenKen). They're similar to sudoku, but in these puzzels, the numbers are actually treated as numbers, and you have to reason about arithmetic operations on those numbers to solve these puzzles---in addition to typical sudoku-style logical reasoning. There's something for everybody in this book, from easy to difficult, and there are various different types of puzzles (using simply the numbers 1 through n, but also starting at zero, or from -m to +m, and using other operations in addition to +, -, x and :). All solutions are in the book, and you can score points for solutions to the difficult puzzles on the author's website calcudoku dot org.These puzzles will keep you busy for hours, and even outside of holidays they're a great way of clearing your mind!

This book offers a range of increasingly difficult puzzles. Some can be solved in minutes by school childeren, other cost hours of careful calculations. The introduction really helps the untrained puzzler, clearly explaining solving strategies.I bought the book for my upcoming holiday trip; I have to admit that I couldn't wait that long solving these puzzles.
2 of 2 people found the following review helpful. The first thing to place in the suitcase By clm Nice book for holidays, the first thing I place in the suitcase. It's oriented to a wide range of puzzlers, just take the book and all real-life problems look like a joke as compared with the challenge of solving the Calcudoku which is in front of you.
