The "Fantastic Book Of Logic Puzzles" is a neat little puzzlebook for anyone interested in exercising their mind or just thinking away a rainy day. Muriel Mandell starts with some very basic "truth or lie" puzzles and gradually escalates the difficulty to probability calculations by the end. Each section is centered around a particular fantasy/sci-fi theme and is devoted to a particular class of logic puzzle. In here, puzzlers will deal with truth-lie scenarios, probability calculations, elimination grids, measuring puzzles, "cross the ravine" problems, and the like. Children will find this a great introduction to thinking logically, and adults will find the problems in this book fun to solve. Good for any age - highly recommended for anyone interested in these kinds of puzzles.
