A year ago I published a book entitled Magic Square Methods and Tricks. It contains entirely new methods for constructing fourbyfour magic squares and various magic tricks that use those methods. The book got excellent reviews and gratifying feedback from readers, including several highly respected magicians. However, some readers (including some of my own family) thought that I was a bit cavalier in saying that the mental math was easy. So I set out to eliminate that requirement. To my surprise, I found that I could simplify the methods without sacrificing versatility and even extend them to work for larger magic squares. The simplified methods require no more than counting through a sequence of numbers in order while following a couple of rules that describe a path through the cells. Others have previously described such pathbased methods, but without discovering the full range of possibilities. For example, you can start with any number in any cell, count upwards or downwards, and by ones, twos, or threes using the same rules. For magic sums that are even, you will always get 52 successful patterns in a fourbyfour magic square; for odd sums, there will always be 36.
When I extended the concepts to fivebyfive squares, I discovered that the rules to describe the path could be even simpler and the results could be even more impressive. The wellknown stair method is easy, but the magic square it produces barely satisfies the definition. My new method can start in any cell, use any sequence in either direction, and will always produce a magic square with 120 predictable, symmetric, easily remembered patterns. If you want to count the predictable ones that are nonsymmetrical (and hard to remember), the number is an astonishing 690. Again, you can fill out the square as fast as you can write the numbers because you are only counting through the sequence. For the first time, there is a method for fivebyfive magic squares that is practical for live performances. The result of these new discoveries is a second book, entitled More Magic Square Methods and Tricks. The magician in me wants to keep these secrets close, so you will not see it advertised, and you will not find it everywhere. But the scholar in me says I must share, so the book will be released at Magic Live! in Las Vegas later this month and available thereafter from a very few dealers. It's a high quality linen bound hardback book with 212 pages, and it costs $50. I am well aware that only the most seriously interested parties will pay that much, and that is fine with me. I will be glad to answer questions to readers of this forum.

I do a 5x5 magic square. I'm starting in any cell with any number. All numbers are in sequence. I do my 5x5 magic square in less then one minute.
I shared this method only with only a few magicians to keep it secret. I recently published an extremely simple method for a 4x4 magic square based on Dürer's square. Once learned the method is impossible to forget! http://www.lybrary.com/melencoliap921956.html

I have this manuscript and recommend it, along with several others from lybrary.com. Anyone who is interested in magic squares should be aware of the modern methods for constructing them. There are several similar methods with interesting variations, but all of them are better than the old methods.
My latest book contains a comprehensive examination of patternbased methods for both fourbyfour and fivebyfive squares. However, it does not expose or replace any of the work of these other authors. If you are reading this topic, you should want all of them.

Hi Jimso, thank you for letting us know about your new book. I have your first book but I haven't had a chance to read it yet. I have been lately interested in learning magic square methods and I'd be interested in getting your new book. I would really prefer an ebook version for many reasons. Is that something you have considered?

Yes, I thought long and hard about that. For several reasons, I rejected it. The material is really more suited to a hard copy. In the preface, I compare it to a recipe book that you come back to over and over, rather than something you read through and discard. There is a lot of depth that you will not fully appreciate on one, or even two or three, readings. Secondly, it is very hard to protect ebooks from piracy. They are so easy to copy and redistribute that you might as well just put everything on an open website. Thirdly, I consider the secrets to be worth protecting from those who are mere curious. The book is expensive enough to discourage casual lookers.
Thanks for your interest, and I hope you find the material to be worth the investment.

Thank you for your response. I understand your concerns about piracy. I prefer an ebook because it is hard for me to read physical books due to a neck/back issue. A computer screen is ideal. I can also read on my phone when I'm traveling. I would even pay more for an ebook than a physical book. Anyway, I am still very interested and will order the physical book.
Best Wishes

I stand corrected on one statement I made above. Forum member hcs pointed out to me an old obscure reference to a method for fivebyfive squares that would be practical in live performances. So I was wrong to say that it is now possible for the first time. My book goes far beyond that historical reference, but I am grateful to have the record clarified. Thanks to HansChristian for that correction.

The book is now available for ordering through Stevens Magic Emporium, www.stevensmagic.com. It will also be available at Magic Live! next week. For the initial release, those are the only sources.

Jimso New user 53 Posts 
I should have mentioned that initial supplies are very limited.

Jimso New user 53 Posts 
The first print run sold out, but more are on the way. You can still place an order with Stevens, and it will be sent as soon as available.
For those who want to see reviews before ordering (understandably), it may be a while because the magazines have a lag time of several months. Maybe someone who has the book will post a review here.

I'm sure Jimso wrote the new gold standard. His two books are a "must read" for every seriously writer about magic squares. My full recommendation for a purchase.

The book is back in stock now at Stevens. I was surprised by the demand, so I apologize to those who had to wait while more were printed.
