Wow!!! That was not easy at all. There were so many pitfalls but a very very nice solve. Each small deduction felt so rewarding. Nothing was ever very obvious. Each digit had to be earned and did not really even the next one or two steps very smooth. Had to do heavy wading through this. Thanks a lot for sharing this masterpiece.
