Panmagic square

A panmagic square is a special kind of puzzle where numbers are arranged in a square grid so that all the rows, columns, and diagonals add up to the same number. Imagine a big rectangle divided into smaller squares, and each square has a number in it.

When you add up all the numbers in any row, they should equal the same number as when you add up all the numbers in any column. And if you add up all the numbers in a diagonal line going from the top left corner to the bottom right corner, or from the top right corner to the bottom left corner, the total should also be the same as the other numbers.

This puzzle can be very tricky to solve because there are many possible solutions, but only a few that meet these conditions. Once you solve a panmagic square, it can be really satisfying because it requires a lot of thinking, logic, and math skills to get it right.
