Print and play
Print and play (often abbreviated PnP) is a game distributed as a PDF or image set that players print at home, cut out, and assemble themselves. It's the cheapest way to share a prototype or sell a finished game without ever holding inventory.
Why it matters
Designers reach for PnP during playtesting (send a PDF to a remote tester) and again as a low-risk first product (sell the PDF, skip manufacturing). The tradeoffs are home-print quality and the time players spend cutting.
Example
A 54-card PnP deck is usually a letter-size or A4 PDF with 9 cards per page (3 × 3), including crop marks at every corner. A player prints 6 pages, cuts with a paper trimmer, and has the deck.
