This is a fun series of puzzles. I think the rule about shading is already perfectly clear, but here's my attempt at rephrasing, although I will leave it for others to judge whether it's an improvement:

"Every cell which contains a value exactly one greater than an immediate neighbour (diagonally or orthogonally) within its box is shaded"

I think the shading rule could/should be better expressed. If you have any ideas/comments please leave them here or in this forum topic: http://forum.logic-masters.de/showthread.php?tid=2127
