You're wrong, this is totally solvable without guessing necessary.

Solved without any guessing.

I was able to solve this one, but I had to look two moves ahead to do so. It wasn't that hard to keep in my head through, so I'm going to call this one solvable for now. Jan, please let me know if you think otherwise.

Found to be logically solvable by Gator.

You can place all but 3 of the reds and you can place 4 blues with plain line/color logic. Then, like gator said, by looking a few moves ahead lets you finish it. It borders on guessing.

Good puzzle, Brian. No guessing required. It was apparent that the blues were zigzags and I could easily tell where the zigzag starts and ends by looking at the clues.

Very neat wall fun :)

I definitely should have been more clear on this one.

We are going to start on the left with the 5 blue clue in row 11. We are going to look two moves ahead to see how rows 15-17 are affected.

When R11C1-R11C5 are blue, then (looking two moves ahead - look at all those dots!) R15C7-R17C7 would have to be blue. So R11C1 is a dot.

When R11C2-R11C6 are blue, then we will see it is impossible to finish row 16 when looking two moves ahead. So R11C2 is a dot. Then some line logic.

Looking at the possible places to put the 3 clue in row 10, R11C6 will always be blue. Line logic to finish.
