Man...I hate .NET debugging but I'll give it a shot. It just adds to the challenge. =D

Ok, I understood the algo.
But how do you fill a 8x8-Matrix with 3 coords per step (+/- 1 field and not in line) and hit each field only once or three times?

The Keygen will have to do this ...

Good luck to all others who have the same problem.

ok, I forgot the coordiante (i;j) with 0 <= i,j <= 6

But the keygen has to understand it also :-)

KeyGen is working for i and j != 2 or 5 ...

... keep going!

@alsor keep it up. but i forgot to add an important function to the program making it easier it should be fairly easy if you have a better look at it.

please see KernelJ's keygen; it's very cool

awesome keygen ;D

Gold medal to kernelJ cheers. The keygen is gr8. I had a totally different idea about it but it turned out to be a bit different(i forgot to add a function :P LOL). And about that constructor i just thought it wd be redundant :)......

heh, my approach was a bit easier then kernelJ's, I allowed two blocks to overlap, so i only had to remove the tile which had name, then place blocks all over to invert it
cool keygen :p

congratulations to KernelJ

I didn't have the idea to put the first L into the middle of the squares :-)
