Difficulty score 78. No green.

no green, maybe, but you probably used your sonic screwdriver.

He gave it a jelly belly and made friends with it, and then it yielded up its secrets.

Today's was easy, No sonic screwdrivers, or spanners or anything else needed. Just one short simple coloring chain.

Mmmm... Jelly babies. You're making me hungry.

Go!

If my record keeping is accurate, last month we had 15 experts. That is a new record. Again, almost half the puzzles were experts.

My first adventure at coloring didn't work out. Doing something wrong.

The second didn't work out either.

Nuts.

I think I'll start the whole thing over and try to get coloring right.

What do you mean by "coloring"?

Dalebo. With coloring, you use the red and green to mark a separate color for each element of a duo -- a duo being exactly two occurrences of the same digit in a constituency. Some duos are pairs (two digits in a cell), some two occurrences of one digit in a constituency but the cells may have more than two digits. Chains of these -- red, green, red, green -- come into conflict if two digits of the same color appear in one cell or if a digit appears twice in a constituency having the same color. Google "Coloring chain Sudoku.

oh - phone call, big break there, no keeping track of time today.

have to say, I don't use the reds at all.
