This one took a little longer and was a little messier. There was a Type 6, a Type 1, an ER and an XY-Chain finished it off.

Marty,

I found the UR's, and then an ER solved it. No chain at the end.

As you can imagine, I enjoy finding those rare puzzles where a Type 6 UR is on the simplest path to a solution.

I did it all with just UR's. Smile
