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 120 and 108. Based on these two big magic squares, the inner order magic squares multiples of 12 are studied. By inner orders we understand as the magic squares of orders 96, 84, 72, etc. Instead of working in decreasing order, we worked with increasing orders, such as, orders 12, 24, 36, etc. The construction of the **block-wise bordered** magic squares multiples of 12 is based on equal sum blocks of magic squares of order 12. It is done in six different ways. First three ways are such that each magic square of order 12 is composed by blocks of orders 3, 4 and 6. The forth way is **bordered **magic squares. Two blocks of order 12 composed with small blocks of order 3 and 4 are **pandiagonal**. This lead us to write all orders multiples of 12 as **pandiagonal** magic squares. The only difference is that the **pandiagonal** magic squares multiples of 12 are no more **block-wise bordered** magic squares. Moreover, the magic squares from orders 36 onwards are **block-wise bordered** magic squares. Below are details of these 6 types:

- Blocks of Magic squares of order 12 with blocks of order 3;
- Blocks of Magic squares of order 12 with blocks of order 4;
- Blocks of Magic squares of order 12 with blocks of order 6;
- Blocks of
**Bordered**Magic squares of order 12; - Blocks of
**Pandiagonal**Magic squares of order 12 with blocks of order 3; - Blocks of
**Pandiagonal**Magic squares of order 12 with blocks of order 4;

The advantage in studying **block-wise bordered** magic squares is that when we remove external borders, still we left with magic squares with sequential entries. The **bordered** magic squares also have the same property. The difference is that instead of numbers here we have blocks of equal sum magic squares multiples of 12.

For multiples of orders 4, 6, 8 and 10, see the following links:

- Block-Wise Bordered Magic Squares Multiples of 10;

The advantage in studying **block-wise bordered** magic squares is that when we remove external borders, still we left with magic squares with sequential entries. It is the same property of **bordered** magic squares. The difference is that instead of numbers here we have blocks of equal sum magic squares of order 12.

For this work the examples below are only up to order 72. Higher order examples can be seen in **Excel file** attached with the work. The total work is up to order 120. Below are links for the download of work:

Below are some examples studied in the work. The work is up to order 120 but the examples below are only up to order 72. As written above, in each case, there are four examples:
