This series contains manuscripts and published material describing games and the rules for playing them. All items are in English, unless otherwise indicated in brackets in the folder title.

Numerous manuscripts were written by Sid Sackson and consist of drafts and notes that show development of his games over time. There are also several sets of published rules for some of Sackson’s published games. Some of the game descriptions in this series were transcribed by Sackson, but he was not the author/designer of the games. Many items in this series do not have an obvious author, publisher, and/or date of manuscript/published rules. Sackson usually noted on an item the date he received it, but this may not be the date the item was written or published. He also often made the notation “See [date]” on items, which are his cross-references to entries in his work diaries (Series I).

Game descriptions or rules that were sent to Sackson as attachments or enclosures to correspondence are filed in Series II: Correspondence with the letters they accompanied. Materials held in this series were previously separated from any correspondence or publications.

References in folder titles may indicate how Sackson game prototypes and several game prototypes by other designers are identified in the museum’s holdings, per their Object ID numbers. (Many of the Sackson-originating prototypes in the museum’s collection are unlabeled, undated, and/or incomplete. They are cross-referenced below only if they have game descriptions included in this series.)
