Very nice. For a long time I thought it was a lobster. Couldn't figure out what "pink" had to do with a lobster.

Lovely image. I hadn't gotten to this one yet.

Lots of fun. I love the image. It was good even with the guessing.

"My" method, Robyn???

I got the first couple of steps that Gator took, but didn't make it the rest of the way. However each of his steps is perfectly clear once it is pointed out.

Hmm...the whole point of the rating system is to help people find puzzles that are of an appropriate difficulty level for them. This puzzle is fine if (1) you are fond of straining your brain over really hard logic puzzles, or (2) you are fond of pretty pictures and don't mind guessing based on "picture logic" when the going gets tough.

The problem is that the difficulty ratings assigned by those two sets of people just get averaged together. So if we tag this as "logically solvable" which it technically is, then it shows up in the ratings as a moderately difficult logically solvable puzzle, which it isn't.

Maybe I should have two difficulty ratings for each puzzle, how hard it is to solve logically, and how hard it is to guess. But I think that making the rating system too complex just makes it more confusing and doesn't end up being that helpful.

I can imagine 50x50 puzzles that can be solved only by performing a sequence of hundreds of subtle moves like the ones Gator describes above. Assuming some madman actually worked out the sequence and posted it, would we then rate that puzzle as logically solvable?

I guess we probably would.

So I guess the only consistent thing to do is to say that it is logically solvable, and I guess it's better to be consistent.

Maybe the best fix is if I add more ratings to the the Solvability scale:

• Requires much guessing
• Requires some guessing
• Logically Solvable by line & color logic alone
• Logically Solvable with some advanced techniques.
• Logically Solvable with lots of advanced techniques.

The "line & color" category would always be flagged by the checker. The distinction between the last two would be subjective.

Found to be logically solvable by jan.

Sorry, Adam. Typo. I meant Arduinna's method.

I love it!
