Assassin 2
Posted: Tue Dec 11, 2007 5:16 pm
Hi folks,
Hey, I'm the first to post a WT for this one! Come on guys, where are you all?
The question is: Was this the puzzle where Ruud developed his love of 3-cell cages?
Estimated rating: 0.75. Unfortunately, I messed it up a bit and strayed from the optimum route near the start. Clearly, I can't do 0.75-rated puzzles properly any more...
Anyhow, here's my (non-optimal) WT:
Assassin 2 Walkthrough

Now all singles and simple cage sums to end.
