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. Ten of its seventeen puzzles sit at 15×15, the size where cross-referencing actually starts to matter, with two full 20×20 boards for anyone who wants a longer sit-down solve and three 10×10s at the gentler end.
