I chose to color the puzzle completely first. Once I got the break in, it took about 20 seconds to fill in the entire thing. This was absolutely the most enjoyable puzzle I have played in a long, long time. Thank you for setting and sharing!

I agree with the previous comments about the difficulty, it should be 2 stars. Could this puzzle be inspired by "Germ-Man Whispers" by heliopolix?, the solving path is very similar.

Wow, very enjoyable! Thank you! The puzzle almost unfolded itself step by step once i settled on a "parity choice" as it were.

Nice and interesting puzzle, although I’d say it’s a 2 star for difficulty due to the break in.

Absolutely loved the break in, it took me about 25 minutes to get a single digit and about 2 to fill in the grid :D

To solve a puzzle to leave a negative comment of this sort takes the biscuit!!
Thanks for your puzzles Gerhard. 1963 was a very fine vintage I can say from experience!

Felt more like a 2 star difficulty, but once you break in, it flows beautifully
