The creation and solution of magic squares has certainly escalated over the last several years. But, I hasten to add, for me and possibly many others, it was Harry Lorayne's books and tapes that piqued my interest not only in magic squares but in the broader area of mathematical magic. I am forever indebted to him for introducing me to this form of entertainment.

I have today released a new magic square method: "Birthday Magic Square" https://www.lybrary.com/birthday-magic-square-p-923360.html There is zero math and the effect turns out to be stronger for spectators. This has become my favorite impromptu magic square effect. People are loving it.

Thanks Chris! It was really a refreshing booklet! I can really recommend it!

The good thing about the new generations born after 2002 is that if you split their birthdays in four pieces (example 2008-may-31), you will get 31, 5, 20, 8 and no number will stand out as suprisingly high as the case is where people is born 1950-1999.

Gus, thanks. I am very happy you liked my recent publication. With my method all numbers cluster around the numbers that have been entered by the spectator. And on top you have a bit of flexibility to shape in which direction they will lean.

It's not enough to just read Jim Solberg's books once. I'm constantly finding new ideas and suggestions because my knowledge and point of view are also changing. For example, I just found an excellent idea to force a magic sum in Jim's new book.
Thank you for sharing your knowledge!

very good work! I like the concept of the basic square with the zones. to enter in the trick with 4 different numbers instead of a "two digit number between 34 and 99" makes it "more random"...

I will release the new update of Melencolia I next week. Stay tuned!

I finished my update. Read more at Lybrary.com. Enjoy!

The Melencolia update is a big deal, folks. HCS is correct in saying it is the first workable solution for the 6x6 magic square of consecutive numbers for mathemagicians. For those who do not know, the 6x6 case is so unique that it needs special handling. Up until now, the published methods were too awkward to use in a live performance, even though the size is within reason. Larger sizes have workable methods, but would take too long for most audiences. The point is, this is a breakthrough development. Bravo, hcs!

Thank you very much for your kind words! I appreciate that very much. But also your three books are an invaluable source! I read them again and again to get inspirations.

Just when we thought that the only news to be had was about the coronavirus and along comes Version 3.30 of Melencolia! Christmas in March. What a wonderful treat and pleasant news for a change. Looking forward to reading it.

Thank you very much for your kind words! I appreciate that very much!

My ebook about magic squares, "Melencolia I" has seen a substantial update by me. It includes groundbreaking developments for magic squares. If you have purchased an earlier version at Lybrary.com, go to your digital shelf and download the new version.

===========================================================

If you have not yet read this ebook and you have an interest in magic squares, I strongly recommend the ebook:
https://www.lybrary.com/melencolia-p-921956.html

My favorite trick is One More Thing. I dedicate One More Thing to Jim Solberg with sincere gratitude.

It is nothing short of impressive how this marvelous encyclopedia is developing and growing. Hats off to hcs for his constant dedication and the generosity to share his vast knowledge with us.

@Nicolino
Very much appreciated!

While as a retailer of Melencolia I do benefit from its sales, I have also explored, performed, and investigated magic squares for 30 years. Actually my entry into magic was through magic squares, which is rather unique in terms of entry points into a magic passion. What Hans-Christian has written here is astonishing. It pushes the methodology to new frontiers. Folks with a passion for magic squares, or math, or clever methods where you use your brain rather than your fingers will experience a lot of joy reading this ebook.

For anyone who loves tricks with magic squares, there is a lot to absorb from the latest version of Melencolia. You can study it for a long time, which is reason enough to thank hcs for his incredible generosity. However, if you are not sure it is worth the trouble to make that effort, I would like to alert you to a huge payoff. Take a peek at the end of the manuscript, where there is an effect he calls One More Thing. Ignore the method on first reading and just imagine the response of the audience. If that does not inspire you to learn the method, you should give up magic squares.

@Chris and Jimso
Thank you very much for your warm words and recommendations!
