What Is a Group of Jigsaw Puzzles Called? (No Official Term — Use These)

English has no specific collective noun for jigsaw puzzles. Use a general or descriptive phrase:

Standard Collectives

• A collection of jigsaw puzzles (implies curation, ownership).
• A set of jigsaw puzzles (implies sold/designed together — e.g., "4-pack").
• An assortment of jigsaw puzzles (variety pack).
• A stack / pile / box of jigsaw puzzles (physical arrangement).
• A library of jigsaw puzzles (metaphorical — for serious collectors).

Creative / Contextual

• A puzzle hoard (affectionate, large quantity).
• A backlog (unbuilt puzzles — gamer term).
• A rotation (puzzles currently in play cycle).
• A stash (hidden/secret stash).

If They're Connected

• A series (same artist, theme, brand line — e.g., "Ravensburger Disney Series").
• A triptych / diptych (2/3 puzzles forming one image).
• A mystery box (unknown contents).

Bottom line: "Collection" is the most accurate general term. "Stash" or "backlog" if you're a puzzler. Invent your own — language evolves!
