The disc may only pass through the goal in the scoring direction, passing otherwise results in a turnover. Like ultimate, turnovers also result when a disc is dropped, intercepted, or goes out of bounds, or when the thrower is stalled. The thrower has 5 seconds to throw, the duration of which is enforced by opponents' stall count. Unlike ultimate, a stall count may be called from anywhere on the playing field, provided it is audible to the thrower. After any turnover or score, the disc must be passed beyond the clear line before the next point may be scored. Play is continuous, with no pause after scores or clears.
Most throwing and receiving rules are identical to those of ultimate. Defensive rules differ in that inadvertent picks are not a violation in goaltimate, and zone defense directly in front of the goal is illegal.
Subsitutions occur on the fly, so teams typically take the opportunity to make subs immediately after gaining possession of the disc.
Games are usually played to 5, in a best of 5 match.
