First-ever Digital Root puzzle book that incorporates Letter-Root and Word-Root. www.mindkam.co.uk Join the community. Enjoy the Challenge.

This book contains Last Root Standing Puzzles to train you for the MindKam Challenge.

After a brief origin story and what-is/how-to introduction to digital roots, you will head for the challenges. You also get the DR prized rule of 9 plus my rule of I and R. Once you know these simple little hacks, you will be flying.

The challenges come with my solutions at the back.

The games are suitable for most people over 12, though younger puzzlers can also learn letter and word roots. I am creating a book for younger puzzlers that will be out soon.

Your guide to the challenges is Seven 'n' Five, a duel character who was once two numbers (7 and 5) and is now a number 3 with two minds. Digital roots can play tricks on you.

I have taken this challenge everywhere, applying digital/letter/word roots to the world around me. Now much older, I am pleased to be able to use this tool to either sharpen my thoughts or clear the fog.

This book makes a great gift and a talking point. Challenge colleagues, friends, and family with the new skills you have gained by completing these puzzles.

Suitable for all levels. Beginners and seasoned puzzlers. Teens, Adults.

This a UK English spelling version, though that characteristic plays a small part in the challenges. All English speakers can enjoy this very first-ever Digital Root Puzzle book-hours of fun.

Many thanks, Terry Liddiard
