Done. 1 guess.

Done, no guesses.

Usually Phil, when you fill all the greens in, you see at least one square where there is only one number which will fit, and that number leads to another and so on.

But I have no idea what an either way virtual is either.

it sounds like a forcing chain or possibly and xy wing

If someone could enlighten me on exactly where the square on this puzzle that unlocks it is and why I would appreciate it. I must be a bit dim but can't see a square where there is only one possibility.

Probably needs someone who hasn't done it yet to hopefully arrive at the same tricky bit after filling in 5 squares all in the top third

Might help a few others who have to guess on the experts at some point

Difficulty score 34. No green, the second time :).

The server threw a fit and the first time I finished it didn't register. Normally that would be quite frustrating, but this one was so easy it didn't really matter much.

Yesterday's expert - 62. Not too bad after the first trick.

only 1 hesitation then straight through to the end

Help me out drwho, how did you spot the trick?

32 filled in and trying without greens

3's, 7's or 9's the key, probably coloring. Greens tempting.

Phil, you still there?

Hummm...click fest.

Sorry man gone for awhile, must have missed something easy on this one.

phil check rows 3 and 9 for the trick that solves todays

nope, can't see it

Next time I see an "either way virtual" or a "block pincer" I'll announce a Spoiler Alert and give a better clue for finding it.

done, ng 1ugess

that would be 1 guess - fingers on wrong keys

Did it, no green, no guess. This time there was an "either way, fill it in." These tricks happen when the open cells for one number form a loop around the board. Choosing one of two possible cells for a number in one block results in that number appearing in a particular cell of another block. Choosing the other cell in the first block and going around the loop in the opposite direction results in the same cell. So, either way, just fill it in. SPOILER ALERT 1! I'll tell you that the number is a three. SPOILER ALERT 2! I'll tell you that the initial block with two openings for a three is upper middle. SPOILER ALERT 3! I'll tell you that the block where the three goes in the same place either way is lower right, if I remember.
