Logicsmith Exhibition 2: Polyominous

Would you like to try your hand at logicsmithing, and possibly be featured on my blog? Read on!

In an intriguing experiment on its online puzzle site, the Japanese company Nikoli asked its authors to create different Slitherlink puzzles all using the same arrangement of givens. I've decided to try a similar experiment here, using the puzzle Polyominous (link to rules, Polyominous puzzles from my blog). Your challenge is to replace each of the question marks in the grid below with an integer to create a uniquely solvable Polyominous puzzle.
For those of you who were around for the first Logicsmith Exhibition, I have followed your advice and opted for a smaller grid than last time. I noticed that the huge group of 32 unclued cells in the middle seemed to be a bit of a choke point, so I tried to avoid that. Also, this grid contains an unusually high density of givens -- 50% of the cells are givens, in fact. Finally, I'm giving you three weeks instead of just two. These factors should make it considerably easier to construct a puzzle (I hope!).

Send your puzzle (and optionally, its solution) to my e-mail address at After three weeks (meaning the deadline is December 16), I will post the puzzle I have constructed for this layout, as well as some of my favorite submissions from other people. Good luck, and have fun!

I've crafted a couple puzzles. How do you recommend digitizing them? Do you have a template for Paint.NET you can share? Will you take our givens in some format and create the png yourself? What's best for you?

You may send your puzzles in any format, and I will make the image myself. :)

Just sent you my own submission. I can only do so much with such a high given density, but it's an alright puzzle. I much prefer the one I made for the first Exhibition, which I'll be sending along in a couple of days. I want to solve the others first to see how I did in comparison... - ZM

Thanks for your submission! I'll probably have a less dense arrangement next time around. :)
