Ultimate is a sport that inspires players and fans alike because of its ability to develop and showcase the athleticism, skill, teamwork, and character of its participants. The arc of the disc in flight, the opportunity for each individual to contribute equally to their team's success, and the trust given to each player to know and uphold the rules make ultimate a sport that is embraced for its fun and excitement on the field and for the community beyond it. As a low-cost sport requiring minimal equipment, offering single and mixed-gender play, and providing a format that builds communication and conflict resolution skills, ultimate provides a welcoming, high value experience for players and fans from a diverse set of backgrounds and experiences. The Official Rules of Ultimate 2020-2021 describes how the game is played, including how players self-officiate and apply the principles of Spirit of the Game in competition.

The Official Rules of Ultimate 11th Edition describes how the game is played. It is assumed that no player will intentionally violate the rules; thus there are no harsh penalties for inadvertent infractions, but rather a method for resuming play in a manner that simulates what most likely would have occurred absent the infraction. In Ultimate, an intentional infraction is considered cheating and a gross offense against the spirit of sportsmanship. Often a player is in a position to gain an advantage by committing an infraction, but that player is morally bound to abide by the rules. The integrity of Ultimate depends on each player's responsibility to uphold the Spirit of the Game™, and this responsibility should remain paramount.
