Like Sudoku it is a matter of finding a strategy to put the squares into a particular order. The early versions used the digits 1 to 8 with the 9 missing but modern ones have pictures (which comes to the same thing).
The squares are scrambled and have to be shifted one at a time to form an ascending numerical sequence 1 to 8. It is worth mentioning in passing the Chinese Puzzle ➚ that may well be familiar to you, it consists of a 9x9 grid of squares with one square missing. Any philosopher of the renaissance age would have understood the properties of magic squares.ĭürer's Magic Square: All rows, columns and diagonals add up to 34 Chinese Puzzle In Europe the first unequivocal appearance of the square is in Albrecht Dürer's ➚ engraving called 'Melancholia' ➚ in 1514 where a 4x4 magic square is clearly shown with an arrangement of the first sixteen numbers gives a sum of 34 in all rows, columns and both diagonals.
Thabit ibn Qurrah ➚ (ninth century CE) is credited with introducing the magic square to the Western World. The magic square reached Europe from China by way of the Arabs who brought news of many of the Chinese inventions with them along the Silk Road ➚. This image was first printed in the first or second century CE. It was regarded as the gift of the turtle from the River Lo ➚ (the turtle had the magic square inscribed on its back). The 3x3 solution shown is called the Lo Shu diagram ➚. Solutions were considered to have mystical properties and became part of the Chinese I Ching (Book of Changes) ➚ method of telling the future. The aim of the puzzle is to try to devise a new ordering of the numbers to complete the puzzle starting from scratch. Just as in Sudoku a number can only be used once in the grid. The puzzle is both a numerical and positional problem, as all the rows, columns and diagonal lines through the grid must add up to the same number. The Magic square ➚ is first documented in China two thousand years ago. Magic Square puzzles which involve the ordering of consecutive numbers into a square, comes to us from the mists of history. Puzzles continue to stimulate new development in mathematics, as you can see in the film A Beautiful Mind ➚. For many centuries people have been interested in creating and solving them.
Sudoku has its deep roots in ancient number puzzles. Sudoku originated in Switzerland and then traveled to Japan by way of America. The name Sudoku or more correctly 数独 comes from Japan and consists of the Japanese characters Su (meaning 'number') and Doku (meaning ‘single’) but it was not invented in Japan. The long and interesting history of the Sudoku is quite a puzzle in itself. Today's Dragon Tip Need Help? You can submit a puzzle to a web site forum to get help directly from within the program.
