#1: bugaboo (bugaboo) on Mar 17, 2012

the end can be solved with a sort of inverted smile logic
where the remaining 1 clues are on opposite sides of the larger remaining (4) clue instead of being both on one side as is typical
kind of cool
i dont know if i have seen this type of smile logic before
no guessing

wait until you see the next puzzle then yoda

A fun puzzle but something you shouldn't try at home!

No, Running Man! Don't run with garden shears!

I have a different end-game than you, bugaboo. Starting with color logic on the blue 3 in r20 and the blue 3 in c2, both can be placed entirely. Then line logic fills almost all of the grid.

There are still left:
- one pixel each in the four black 2 clues from r15 - r18
and correspondingly
- the black 1s in c7 and 11
- the black 2 in c9

To the experienced eye, these will make a zig-zag. However, to prove it, you can use a couple methods:
- extended edge logic on either vertical 1
(eg. if the 1 in c7 goes in r17, then that will force the 2 in r18 to extend into c9, where the vertical 2 will be cut off - so c7r17 must be white)

- two-way logic on either vertical 1
(eg. if the 1 in c7 is in r17, then c9r18 is white which forces c9r15-16 to be black; if the 1 in c7 is in r18, then c9r18 is white, forcing c9r16 to be black: either way c9r16 is black.)

Then a tiny bit of line logic to finish.

Looking at the 2, I think I see what you were saying, bug. I took the 4 in your hint as being a clue rather than the size of the space.

The vertical 1||2||1 definitely makes an extended, bent smile. :P

However, the 2 in c9 can also have plain edge logic applied to it (eg. if it were to go all the way to the top it would kill the 1 in c11. So c9r15 must be white, then line logic to finish.)

So, actually easier than regular smile logic, or any of my other ways above.

Fun puzzle. Love the video!

Found to be logically solvable by gator.

I used the plain edge logic way. :)

Nice puzzle.
