Cool! Not easy, but easier than others in this series. No guessing.

Enjoyable solve.

Question: how come this puzzles cannot be rated for solvability?

Re: Jota
When I create a puzzle, the creation tool has a checker which is very powerful, and can discover if the puzzle has multiple solutions. The checker also looks to see if the puzzle is solvable using only line logic, or only line & color logic. As long as the checker determines that the puzzle can be solved using one of these two methods, then when the puzzle is published the solvability status is pre-set.

One of the admins can probably explain more about how the system works and why it was setup this way. Props to whoever created and/or improved the creation tool checker, it greatly increases the speed at which puzzles can be created and tested.

I am very careful when I add blots to make sure a puzzle never moves beyond line & color logic only. My goal is to get the puzzle close to that line, but to never cross it.
