Magic Number Square

What does a magic square look like?
3x3

4x4

What is a magic square?

A magic square is a NxN square when the digits are added diagonally, vertically, and horizontally all equal the same number. For Example...
down
2+9+4=15
7+5+3=15
6+1+8=15
across
2+7+6=15
9+5+1=15
4+3+8=15
diagonal
2+5+8=15
6+5+4=15

How does it work?
1. Add four extra square like shown in the picture titled before.
2. Then starting with the green square write one and count up diagonally. When you run out of squares jump down to the diagonal square below the number 1 and repeat but for number 4.
3. "Fold" in each extra square. Follow the color pattern just like the picture!
Hint: The middle number in the number line is always the middle number in the square!
