Hello Reader! I'm Marie Freeman, and I absolutely LOVE riddles and brain teasers! They're so amazing to me because they both let you have fun and improve your cognitive functions at the same time! You see, I produced this book because I wanted to create something ESPECIALLY designed to entertain you as well as IMPROVE YOU as much as possible. I tried putting together all the best riddles following the most precise criteria of selection, making sure they actually train and strengthen your cognitive skills. This book will be a book that challenges you, a book you can come back to every time you're bored or feel like a little brain-workout! I grouped the riddles into various sections so you will get challenged in multiple ways! From lateral thinking to classical puzzles, this book has it all! I really am convinced you will love this, and in here there is enough material to keep you engaged for many travels! I have spent lots of time by myself and nearly traveled my entire life that I always wished someone would produce a book like this...
