Puzzle Description:

Have a nice day.

A little edge logic on the 10 in c1 to eliminate r1-2 is all that's needed apart from line logic.

very nice! love the viewpoint! I had no idea 'til it was done.

Why is it 70s?

:) bak @ ya

nice puzzle joe :)

...alternatively, if you EL dot just C1R20, then it's LL from there also. that's half the amount of edge logic you describe ;P

I really feel dumb, but what am I supposed to see? lol

It's the lower left corner of a smiley face button. :)

Now I feel even dumber. Now that I know what it is. Neat puzzle.

Sorry, Thomas - it's another americanocentric puzzle, or at least the title is. The yellow smiley face (particularly with the "T"s at the ends of the mouth) was ubiquitous in America in the 1970s. Mostly in conjunction with the phrase "Have a nice day."

Found to be solvable with moderate lookahead by infrapinklizzard.

And I forgot to rate the solvability - oops.

David - I realize you're being facetious, but it raises an interesting point. bugaboo would often put the bare minimum of pixels needed as well. What I did here was to put what I saw as the first piece of edge logic I did.


There are at least two ways to do edge logic - piecemeal or positionally, and holistically.

The first way is to place the clue in each possible position and to rule out each one as you go. This would give you a maximum of one pixel ruled out at a time -- a piecemeal approach.
[In this case, you'd hypothetically start the 10 in r1 and realise that there'd be a conflict in c2r3 and so rule out r1c1. You could then continue on to rule out r2, but you don't need to in order to finish with just line logic.]

The second way is the way I tend to think. It uses the content of the comparison row to quickly locate places where the placement row cannot go. This really doesn't have a maximum pixel count, as you can rule out large swathes if the comparison clue cannot fit (eg if there's lots of alternating 1s and non-1s crossing a long clue).
[In this case, since there is a 9 in c2, the 10 in c1 cannot reach above r3 without creating a too-short block in c2. Therefore everything above r3 (ie c1r1-2) is white.]

so what you're saying is....i win?

with sprinkles on top

cool! neat puzz


hahahaha @ 12/13

hmm...sprinkles on top usually make my puzzles have multiple solutions :(

That's why you can't see the top here. :D

Fun puzz, Joe! Congratulations for the sprinkles, David.

Took a bit to see. Fun solve.
