During past years author worked with **block-wise**, **bordered** and **block-bordered** magic squares. This work make connection between **block-wise** and **bordered** magic squares. We started with **block-wise bordered** magic squares of orders 144 and 126. Based on these two big magic squares, the inner order magic squares multiples of 18 are studied. By inner orders we understand that magic squares of orders 108, 90, 72, etc. The construction of the **block-wise bordered** magic squares multiples of 18 is based on **equal sum blocks** of magic squares of order 18. We have taken **37 different types of magic squares of order 18**. The advantage in studying **block-wise bordered** magic squares is that when we remove external border, still we are left with magic squares with sequential entries. It is the same property of **bordered** magic squares with single digits. The difference is that instead of numbers here we have blocks of equal sum magic squares of order 18. For multiples of even orders 4 to 16 see the links below:

1. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 4.

2. Block-Wise Bordered Magic Squares Multiples of Magic Squares of Order 6.

3. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 8 – Revised

4. Block-Wise Bordered Magic Squares Multiples of 10 – Revised.

5. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 12 – Revised.

6. Block-Wise Bordered Magic Squares Multiples of 14 – Revised.

7. Block-Wise Bordered and Pandiagonal Magic Squares Multiples of 16.
