What's the difference between magic squares and sudoku?
While magic squares are similar to sudoku, there's one key difference. In magic squares, the rows, columns, and diagonals all add up to the same number. In sudoku, only the rows and columns add up to the same amount. Diagonals do not matter on sudoku.
However, in some of the more advanced sudoku puzzles, there are more restrictions, and this sometimes does yield a magic square. Check out Cracking the Cryptic on YouTube if you want to see one of those (https://www.youtube.com/watch?v=hAyZ9K2EBF0).
