Some rules vary between North America and the rest of the world.
More significant rule changes were made in the Ultimate Frisbee Association pro league games.

Most differences are minor and they can be found online.<ref>{{cite web |url=http://www.wfdf.org/downloads/cat_view/26-rules-of-play/32-ultimate |title=Downloads &#124; Ultimate &#124; Rules of Play |work=Wfdf.org |access-date=March 1, 2017}}</ref> USAU rules have been slowly shifting toward WFDF compatibility.<ref>{{cite web |archive-date=2020-03-17 |url-status=dead  |archive-url=https://web.archive.org/web/20200317101640/https://www.usaultimate.org/resources/officiating/rules/2020_2021rules.aspx |title=2020-2021 Official Rules of Ultimate |url=https://www.usaultimate.org/resources/officiating/rules/2020_2021rules.aspx |access-date=2022-06-28 |website=USAUltimate.org}}</ref>

====UFA rule changes====
The [[Ultimate Frisbee Association]] (UFA), the semi-professional ultimate league with teams in the U.S. and Canada, has its own variant of the rules, and has made multiple rule changes in recent years. Some of the more important include:<ref>{{cite web |url=http://theaudl.com/rules|title=Rules - The AUDL|website=Theaudl.com|access-date=January 2, 2018|archive-url=https://web.archive.org/web/20171217045157/http://theaudl.com/rules|archive-date=December 17, 2017|url-status=dead|df=mdy-all}}</ref>
* Slightly larger field dimensions.
* Shorter, 20-yard end zones.
* In WFDF, games are played to {{var|X}} points with two halves and global time caps. In the UFA, the game is played in four quarters of 12:00 minutes each. The counted times is only when the disc is in actual play, resulting in games lasting over two hours at times. The game stops on the timed second, rather than at the end of the point. At this point the disc is still allowed to be caught, which can result in "buzzer beater" or "in-bound Greatest" attempts, where players attempt to throw the disc right before the time ends.
* Referees making calls instead of players. Players may invoke the "integrity rule" and overrule the referees' call when the players call is against their own team.
* Most fouls are penalized with a 10- or 20-yard move of position against the fouling team.
* Double-teaming is allowed, but not triple-teaming.
* Stall count is 7 seconds instead of 10 seconds.
* Stall count is counted by the referees rather than the marking player.
