On 2nd try for me. But I believe it's just that those boards with group of directional blocks within confined space suit my mind: I watch and sort of see straight the only way to get it done. I then push and it rapidly works. It's like a puzzle to me and I'm good at that somehow. If only that could be the same with holes boards and pipelining boards... LOL
I can't believe I finally found the 60 ''Odeferous Knaves''. This wasn't easy, at all. Had several sittings, over 4 days ... Was always 8 or more off, but today found a 4 off and soon after that solved it! GREAT combination! (26 tries, officially, unofficially probably much more, including the resets be4 reaching the exit).
