How the Hard preset differs
Hard puzzles use an 18 by 18 grid, twenty terms, overlap, reverse paths, and diagonals. Vocabulary familiarity can still make one Hard topic feel different from another.
This hub explains and browses the difficulty. The Hard Printable collection is the print-first route to the same reviewed pages.
