Inspired by this article I wrote today: http://www.brighthub.com/environment/science-environmental/articles/44257.aspx
My model was the second image. I didn't mark this as a spoiler, but if you click the link, consider yourself spoiled. =)

I managed to solve it by logic alone. When line logic fails you, edge logic becomes your friend. You'll have to be pretty savvy with it. It's possible I made a mistake, though, so if nobody else can do it, I'll rework it. If Adam or Jan can't do it, then I know it's not solvable!

Add Gator to the list, too. He is usually right on.

This is definitely solvable by logic. After doing line logic to get the entire bottom and right side (and some of the left) I used edge logic on the top 5. Simple edge logic lets you place only a couple dots, but looking more closely at the top rows, you see most of the central columns alternating with 1's and 2's to start those central columns. The 5 can not cross through most of that area (it would create 1's in R2) and you can then place 2 of the 5, which then allows you to solve a lot more rather easily for a while; then I got stuck toward the very end again, and had to revert to even more edge logic.

Very tough puzzle, but a great image. I loved solving it. Along the way, once it started taking shape, it kept looking like a dinosaur.

Thanks, Adam. I actually thought of Gator after I wrote that comment. I remember a devilish but beautiful small puzzle he created!

I solved this the same way when I was test-solving. That block of 5 at the top is tricky, but I placed it the same way you did—looking at more than one line with edge logic. But I had to re-edit and test-solve so many times that I began doubting myself. Thanks for confirming it!

By the way, thanks for considering me among the great "solvers" on this site.

Okay, I was able to see the edge logic on the top row, and have it almost solved, and am stuck. I checked the comments hoping there would be a hint. If there is edge logic needed toward the end, I would love to have someone point me in the right direction. I know what it SHOULD look like, but I don't want to guess if there is a way to figure it out with edge logic.

Not sure where else you would need edge logic. I've worked this so much I can't even trust myself! But a possible site would be rows 17 and 18. Or possibly rows 5 and 6.

Thanks - that did it! Great image. And very interesting article. The females can clone themselves! How cool is that. Not much fun, but cool.

Towards the end and besides the edge logic, I used the fact that no matter how the first 2 clue on row 6 was placed, it would cause either R7C6 or R7C7 to be filled in. This makes the rest of what is left of row 7 dots.

Great image and a ton of fun to solve.

Needing a ruling on solvability on this one, too. I personally strive to create only logically solvable puzzles, so if one of mine is ruled as definitely needing some guessing, I want to know so I can edit it. But I believe this one is logically solvable, if you can think about two steps ahead. Which even my patchy short term memory can manage!

I used both edge logic and two-way logic for this one. I only had to look one step ahead for the edge logic. It IS logically solvable.

Robyn, I know how you feel, but don't edit it yet. When you edit a puzzle we have already solved, then we need to go back and solve it all over again. I kind of like it the way it is. Some people will mark it as requires guessing. Then Jan will come along and make a determination. If some of the regulars (like Gator and Adam) post how they solve it with edge logic and Jan agrees, then he will remove the guessing rating and it will be declared officially solvable by logic alone.

Personally, I'm torn between creating puzzles that are all solvable by logic alone, and creating some that are more challenging and need edge logic and risk getting the guessing rating. Oh well, no big deal. It's all fun.

I did it without guessing and w/o reading this comments.

Ditto #14 - it took me a while, but I solved it without guessing or getting too scientific!

Found to be logically solvable by Gator.

Wasn't this Jan's Robot?

See topic #189.

Thanks!

what a fantastic image and a fabulous solve

logically solvable.

Fantastic image.

ditto bugaboo and Shiro

Gorgeous!

Fantastic image. Very tough puzzle. Did have to guess a couple of times.

Since Valerie mentioned this puzzle in the forums, I took a 2nd look at it. After LL failed, there was the previously-mentioned edge logic between R2 C19 and R2 C29. After that, I use edge/two-way logic to place the clump between R5 C8-10 and R10 C6.

I agree with the ruling of moderate lookahead.
