If the line was at the bottom, I'd say "under lock and key".

How about "lucky"? (lock-key)

Nope. They are under. :)

it is under lock and key :)

This was fun. Thanks.

Super fun with the blots!

thank you both kathy and teresa :)

The key is too large for the lock...

lol

Optical illusion. Actually the key is quite a ways in front of the lock.

:)

Well done Travis and I guessed it!

thanks and good for you susan :)

Found to have a unique solution by infrapinklizzard.

Found to be solvable by line and color logic alone by infrapinklizzard.

This is odd. It says the uniqueness and solvability are both questionable. But it is definitely line logic solvable.

Using the built-in helper gets five blobs of black and some white.
Then non-purple-arrow LL makes c13r9 white (no matter whether c12r9 is part of r9's 7 or its 1).
Helper does a lot more.
Then non-purple-arrow LL makes c6r8 black (it must be part of either c6's blot or the 2).
Helper nearly finishes it.
Then non-purple-arrow LL makes c6r13 white (c7r13 must be a 1 in r13).
Helper finishes it.

So, definitely unique solution and definitely LL
And definitely weird on the autosolver's part.

mmm, that is weird :/
