The Simple Book of Not-So-Simple Puzzles

Back

This collection of more than one hundred original and highly sophisti­cated puzzles presents challenges that require creative, “outside of the box” thinking. Many different types of puzzles are included, such as word, number, logical, visual, spatial, dissection, dividing, dot-connect­ing, matchstick, coin, and more. Each aesthetically appealing puzzle is designed to improve problem solving skills; train geometric, combinato­rial, and spatial imagination; bolster visual perception and logical rea­soning; and foster the development of a perseverant and self-confident approach to challenges.
