Very enjoyable! Each step took me a bit of new thought and some time to reason through in the first half, but it flowed very nicely.

Loved it. The Dutch whispers were surprisingly effective in this one. There were couple of really nice things to discover.

Took the plunge on a coin toss as I knew a certain number had to go in one of two cells . . . and the whole puzzle practically filled itself in from there. One day I will learn to see why the other cell couldn't have been that number but for now I'll just keep on filling in until it clearly goes wrong then back out all the way!!!

Keep looking and you will eventually find the logic!
