Yeah I figured, but I didn't know if there was an actual parity error because I was working (impossibly) towards the wrong solution, or if there was a hard part that I might still work through and still arrive at a wrong but plausible solution. Does that make sense? There are enough ambiguous elements in the puzzle that make it kind of cat-mustachy and unrewarding. Do the symbols mean anything, or are they just differentiators? One of them is the reverse-space image of one of the others, is that significant? One of them is a unit block - maybe they go in order of unit block count? What's the physical analog or metaphor of the lock, like pins and tumblers or? Should colors be aligned vertically or horizontally, or not at all? Is there a unique solution?
I see. I guess I need to work on this, make the symbols more distinct or something. You only need to align colors and symbols in either rows or columns, so there's multiple solutions.
