A knight enters the grid at number 1 and then moves, as if he were on a chessboard, to number 2. He visits every square in numerical order, before exiting at number 64.
KEY:
Blue = cube numbers (1, 8, 27 and 64)
Green = squares which are not cubes (4, 9, 16, 25, 36 and 49)
Red = prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59 and 61)
Yellow = multiples of ten (10, 20, 30, 40, 50 and 60)
Purple = multiples of 11 which are not prime (22, 33, 44 and 55)
One number has been added to get you started.

Thanks, Leming!
Last night I made an 8x8 "Killer Skyscrapers" which (obviously) is a combination of Killer Sudoku and Skyscrapers. I just need to check for redundant clues, errors etc, then I'll post it!
It's good to know that you are a kindred spirit! :) I, too, am a glutton for punishment, where puzzles are concerned!
