Penguin Magic July 22nd 2019. I love this Magic Square! This is, by far, my favorite version of the Magic Square, and I have tried many methods. No need to memorize and it works every time! On top of that, the dry-erase board really does fit neatly into an inside suit jacket pocket, hence the “Executive” grid. I prefer to use this with a “Psypher Pro” pad to secretly obtain their chosen number. My only suggestion, and this is NOT a criticism, is that I think they should release this method as a pad as well. Then you would be able to give the sheet to the spectator as a souvenir at the end. They would be able to review the math later on their own and share it with others. Don’t worry about the algebraic border – the math is nonsense and they’ll never pick up on the code. Finally, McCaig/Volpe method of “adjusting” the results to allow for the size of the chosen number is terrific. And it can be used to vary the results even if two people had chosen similar, OR EVEN THE SAME, number. Not that you would be likely to perform this for multiple people in a group, but you could! One final comment – I find the border code to be clear and easy to read without having to use reading glasses! A plus! Highly recommended!
