Magic Squares, the predecessor to Sudoku and a fascination of Leonardo DaVinci, is a multi level numbers challenge where the object is to place numbers in the squares so that the numbers in all rows and columns add up to the same value. The trick is that each number can only be used once. GOOD LUCK"
