Doubles play in disc golf comes in a variety of formats. Best Shot, Best Disc, Alternate Shot, Worst Shot, and Tough Shot. Except where noted, all standard PDGA rules apply. These rules may also be extended beyond doubles to triples or other formats if needed.
Audio versions of the official PDGA Rules of Disc Golf, and Sections 1, 2 & 3 of the Competition Manual are in separate files under the DiscGolf365 account on YouTube. They are also available (along with TONS of other Disc Golf content) @ DiscGolf365.com
