 Extended Knight's Tour (Posted on 2008-07-10)
Our valiant knight is about to embark on a longer tour than usual, but he doesn't mind, because there is a lovely young maid waiting at his destination.

The Knight enters the upper chess board at number 1, visiting each cell, just once, in numerical order. When he reaches number 64, he makes another Knight's Move to number 65 in the lower board. He then proceeds in the same manner until he reaches his destination at number 128.

Can you recreate the tour?
 6
 128
KEY:
Blue = cube numbers (1, 8, 27,64 and 125)
Green = squares which are not cubes (4, 9, 16, 25, 36, 49, 81, 100 and 121)
Red = prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113 and 127)
Yellow = multiples of ten which are not square (10, 20, 30, 40, 50, 60, 70, 80, 90, 110 and 120)
Purple = multiples of 11 not included in any other category (22, 33, 44, 55, 66, 77, 88 and 99)
Gold = multiples of 17 greater than 60 (68, 85, 102 and 119)
Rose = multiples of 19 greater than 60 (76, 95 and 114)

Please refer to the above list of numbers for those which occur in more than one category.

It took me about an hour and a half to do the top part. The only part that took looking several moves deep was trying to figure out the connections of where 12 is now. I realized shortly it couldn't connect to where 33 was now, and then also that it couldn't connect to 27 was now.

After getting that done and getting 36 placed, the rest of the numbers were not hard to fill in.
