For a set of the same kind, pass `count` with `size` (6 to 12, counting the clue row and column) and `difficulty` (easy, medium, hard).\n2. When the puzzles differ, pass one object per puzzle in `puzzles` (`size`, `difficulty`, `seed`).\n3. Layout options are `per_page` (1, 2 or 4), `paper` (letter or a4), `title`, `name_line` and `answer_key`.\n4. Share the PDF link. Tell the user they can also fill in digits and press Check in the card.\n5. Do not write the answers in chat unless the user asks; they are on the answer pages.\n6. To reprint the same puzzles, call again with the same `seed` and settings.\n\nIf the reply notes that a hard puzzle was made at medium for a seed, pass that on and offer another seed. It does not solve a puzzle from a photo and does not make grids larger than 12 x 12.\n"
