In a magic square of numbers, all rows, columns and diagonals have the same sum, or magic total. Here is an example:

1*5*9
8*3*4
6*7*2

(mt=15)

Here’s another:

06*07*11*10
15*02*14*03
04*13*01*16
09*12*08*05

(mt=34)

And another:

04*25*20*10*06
01*13*11*21*19
23*09*07*08*18
15*16*03*14*17
22*02*24*12*05

(mt=65)

And another:

35*15*10*18*11*22
05*25*33*12*07*29
34*30*04*14*21*08
02*16*27*17*23*26
03*24*09*19*36*20
32*01*28*31*13*06

(mt=111)

In all those magic squares, the magic total is fixed: the sum of all numbers from 1 to 36 is 666, so any individual line in a 6×6 magic square has to equal 666 / 6 or 111. In other kinds of magic figure, this rule doesn’t apply:

2*7*3
4***8
6*5*1

(mt=12)

6*3*4
2***8
5*7*1

(mt=13)

8*5*1
2***6
4*3*7

(mt=14)

8*1*6
4***2
3*5*7

(mt=15)
