Took a while for the rule set to sink in and required a bit of a different plan of attack to the other yin yang puzzles I have tried, but it was a fun struggle.

Tough one, I though. But very satisfying 'til the end. I kept breaking it and couldn't figure out why and just restarted and tried different approaches. I usually get angry and give up if I break it, but something made me keep going. Good work pieguy!
