The date 1514 A.D. actually means something to you? It's possible to instantly construct that kind of magic square on the backside of a business card and hand it out as giveaway. I love the method because of its simplicity. Even better: once learned the method is impossible to forget!
 Works with any magic sum greater 33 or with the century and year numbers of any named year.
 The magic square is balanced.
 The numbers are in sequence. There are no duplicate numbers.
 The magic sum can be obtained in up to 68 different ways.
 Extremely simple calculations and memory work.
