There is a guy in prision, and he founds a knife and a key (like wolfstein 3d)..
Now, he must get out of prision but before he does he must kill each and every guard.... the building looks like this from above:
_________
|x_|__|__|__|
|__|__|__|__|
|__|__|__|__|
|__|__|__|_e|
The guy is in the first cell (x), in each of the other 15 cells is a guard, the exit is the last cell (e).
The only condition is that (because of religious reasons or whatever) he cannot goes into a cell where he has killed a guard (and each time he enters a cell he kills the guard and leave the body there and the guards cant leave their cell). The doors are vertical and horizontal (not diagonal).
What's the path he must follow to get out?

There's no guard in his original cell so he goes back into that one.

I convinced myself that would do him no good because one of the adjoining ones would have a body......
I never thouoght of returning after the first kill!!
Well Done!!

I almost did that. It's easy enough to eliminate any simple path or any convoluted zigzag path so that only left returning to the original cell, just a question of when.

Depends on the type of puzzles. My english vocabulary isn't that strong. This one took me maybe 5 minutes to solve but only because there's obviously a trick answer and the trick is pretty transparent if you're looking for it.
