# Roll a deck back to a historical version

> Restores the deck's field state from the historical version at the given 1-based ``version_number`` (matching the order returned by ``GET /decks/<id>/versions``). The rollback is a forward-saving event -- the historical chain GROWS by one record. Owners only; non-owners and out-of-range versions alike return ``404 FLEXSLOT_NOT_FOUND``.
