Think of the grid as if the vertical columns left and right were adjacent to each other. and the horizontal rows top and bottom were also adjacent to each other. Start on an outside edge and place the digit 1in the middle of the row or column you selected. move diagonally to the next square outside the grid. Use the idea that the rows and columns are beside each other and go to the position on the opposite side. For example following the 816 357 492 example above , 1 is in the top row center. 2 is up one row (go to the bottom row) and right one column. 3 is up one row and right one column which takes you off the square so back to the most left column. For 4 a up one row and right one column would place you in the square taken by 1. The rule is drop down a square and put the 4 in that square, then resume your diagonal action for 5, then for 6. Another diagonal would put you in the square 4 is currently in, so use the drop down rule for 7. diagonal takes you to the opposite column for 8 and the next diagonal takes you to the opposite row for 9. Every odd numbered magic squares I have seen always has one center diagonal with the middle number in the center and all the numbers above and below it ordered from corner to corner like the 456 above.<br />I have no clue if a pattern exists for even numbered squaresAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1147784181901427860.post-16989408175402517912013-04-10T03:47:59.365-07:002013-04-10T03:47:59.365-07:00reflections would also work!reflections would also work!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1147784181901427860.post-39875961149849958122012-01-04T20:21:49.405-08:002012-01-04T20:21:49.405-08:00Here's the answer:
