Very original ruleset! Tricky at the beginning, and surprisingly at the end - the last line was really tough to solve.

Cool puzzle idea and a lot of satisfying deductions along the lines! :)
I think scanning around the grid was pretty tricky overall, but going slow and steady should help greatly there.

Clever ruleset, solve was still pretty tricky even after I figured out the implication

Lovely steps throughout the solve! Nice new ruleset.

Short, original ruleset? High rating? A series of small "aha" moments? Simple yet powerful axioms that I could work out myself? I'd better comment quick in case Mark or Simon snip the comments!
