Unlock the Power of the Parity Principle

“This is a fascinating work and a tool that supplies the reader with an abundant supply of new and usable material… Self-working effects, based on clever mathematical principles are often a relief to perform and give you ability to concentrate fully on your presentation. Parimental explores just one such principle with some 20 different effects to choose from along with some very sound presentational advice.”– From the Foreword by Richard Osterlind

Discover how to influence your audience’s thoughts and anticipate their choices with the Parity Principle, a simple yet powerful concept introduced by Martin Gardner in Scientific American in 1960. This adaptable principle is perfect for both spontaneous performances and structured routines, making it suitable for any setting, including online shows.

The core routine involves arranging nine items in a three-by-three grid. Participants freely select an object and choose a number, moving in any direction. The performer reveals a prediction that indicates which items are not selected, gradually eliminating them until only one remains. The possibilities for the nine items are endless, and this book offers a wealth of creative ideas to inspire you.

Within these pages, you’ll delve into the fundamentals of the Parity Principle and its many applications, enhancing its versatility. You’ll find routines featuring celebrities, colors, business cards, playing cards, cities, symbols, and more. Additionally, insightful essays will help you refine your mentalism skills and elevate your performances.

This book is not just a resource; it’s a gateway to creating astonishing effects and an exploration of a remarkable principle that will leave a lasting impression.

“Parimental will teach you a mentalism technique that you can use to construct powerful routines of your own. If you’re not the creative type, then Jheff has done all the thinking for you, providing an array of solid presentations. If you are looking for foolproof predictions with kicker endings, you’ve found the source.”– Paul Brook

“So glad Jheff is releasing this book. Just BUY IT! You’ll love it!”– Looch

“It’s so versatile and these are the effects we need. As a corporate performer, I’m always looking for routines that can be custom-made and this is one of those. This is a very good investment. Well done, my friend!”– Luca Volpe
