Can you create a 4x4 magic square that still works with the same total when turned upside down?
[A Magic Square is a grid of numbers whose rows, columns and long diagonals add up to the same total. All the numbers in the square must be different.]
[By 'turned upside down' I mean that if 106 is the number in the top left corner in the original magic square, then 901 is in the bottom right corner of the inverted square]

re: solution - very nice by SilverKnight)
hmm.. i cant really explain it lol its like... i guess a couple of numbers... i kinda figured it would be 2-digit numbers all around coz it cant be 1-digit ands for higher, i just thought it would be simpler than that lol. so basically its a lot of luck and guess & check. oh yeah.. i thought that probably each row,column, and diagonal had like 1, 6, 8, 9 once, so i looked for a number that end in the ones digit 4. eventually i got to that... lol
