Thanks for a great puzzle. I too thought finding the first digit was hard, so I've rated it 2 stars for difficulty.

@goodcity Agreed about the "hard to find a first digit" part. I've been staring at this thing for almost 25 minutes and I've got nothing. I've pulled out SET, windoku, and everything else I can think of and I've got nothing.
EDIT:
Hah. No sooner did I post my previous comment then I got my first digit and then the rest flowed reasonably smoothly. Great puzzle!

Hard to find a first digit, then hard to stop finding digits !
