Game play is relatively quick as a result. NAQT format balances the diversity of subjects found in CB packets with question difficulty often seen in the ACF format. Timeouts and player substitution during timeouts is allowed. In addition, there are power tossups, where 15 points may be earned during an early intrarupt. Game length can vary a little, but a standard length for NAQT is 9 minute halves and a total of 28 tossups.
Questions come from one of three sources.
Organizations such as CBCI and NAQT, or other vendors sell packets for use in intramurals and invitationals. These are written by a small group of professional writers. They also write all of the packets used in tournaments they run, e.g. CB Regional Tournaments, and NAQT Sectionals. The school hosting a tournament may choose to write all the packets used. Members of the host school's team generally write the packets.
