How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 127 of the 225 cells, about 56%, which is enough of a skeleton to work outwards from. The most generous opening is row 1, which gives up 15 cells on its own. 5 of the 30 lines are decided outright by their clues, with no room to slide. From there the board finishes on row-and-column logic alone — there is no point where you have to try a cell both ways and see which one breaks. The finished picture fills 82 cells, and the longest unbroken run anywhere in the clues is 10.
About this category
Symbols, vials, and half-finished experiments — the alchemy set leans into the visual clutter of a wizard's workbench, which turns out to be a good fit for nonograms: lots of small internal detail means real clue interplay between rows and columns, not just one big blocky silhouette. Most of the set sits at 15×15, the size where cross-referencing actually starts to matter, with a couple of full 20×20 boards for anyone who wants a longer sit-down solve and a few 10×10s at the gentler end.
