Solvable via edge logic on the right to get started. In fact, this is the first puzzle I *intentionally* created to require edge logic (in the past, it's just "happened").

Ditto edge logic on R side comment. I kept expecting a "tricycle" and it never appeared. Nice image. Very fun to solve.

Found to be logically solvable by jan.

I can't get beyond a very few squares. Don't see how this is solvable without guessing.

Just re-tested it. You need a little edge logic and a lot of perseverance, but it is logically solvable, though difficult. Hmm, I think I'm going to make easier puzzles for a while. PBNs are no fun if you get too frustrated. Plus, I'm tired of spending so much time test-solving!

BlackCat: Use edge logic on the right. This means first suppose the block of 11 is all the way at the top. What would then have to go in the second column from the right? If it's impossible, put a dot in the top right corner and shift the 11 down by one space. Repeat until it seems possible, then try putting the block of 11 all the way down and shift it up when impossible.

I repeated this process with the bottom row of 3 1 5, and with the left column of 3. Guess I'm getting good at edge logic!
