this is actually pretty funny.

Funny. If you paste the link in the comment box instead of in the description people will be able to go directly to it.

Funny indeed! Enjoyed the solve!

If there was a category for rating how amusing the picture is, this would get a 5.

LL/CL leaves only blue.

Edge logic on the 4 in r7 makes c6-7 white (or there'd be a conflict in r9)

Then edge logic on the 4 in r8 makes c4-7 white for the same reason.

Then line logic to finish.


(Note that you could do edge logic on the 4 in r8 without doing the one in r7 first. However, it's easier to see if the 4 in r7 is done. Also, realistically, the 4 in r7 is more likely to be looked at for edge logic first because it is closer to an actual edge...)

Found to be solvable with moderate lookahead by infrapinklizzard.
