The intention of these rules is to provide additions to the basic rules to create a smooth-running, spectator-friendly, well-resourced elite sports event. Where there is a discrepancy between the Rules of Ultimate and the Appendix, the Appendix takes precedence. These rules set the standard for World Flying Disc Federation (WFDF) events, but should also guide best practice for non-WFDF events. Specifically, these rules should be applied at the following events:
• World Ultimate and Guts Championships,
• World Masters Ultimate Championships,
• World Ultimate Club Championships,
• World Masters Ultimate Club Championships,
• Continental Championships (e.g. Pan-American Championships, Asia-Oceanic Championships, All Africa Championships),
• The World Games (along with other changes as mandated by WFDF and/or IWGA event hosts),
• World Under-24 Championships,
• World Junior Ultimate Championships.
For non-WFDF events, a selection or modification of these rules may be added to the basic rules of play, according to the level of resources available and the standard of play. Basic modifications for a non-WFDF event may include:
• playing surface,
• number of players,
• size of field,
• length of game, and
• field markings.
