Under NCAA rules, a college basketball game is divided into two 20-minute halves, with a 15-minute halftime break in between. However, the actual length of the game can be influenced by various factors, such as timeouts, injuries, ejections, and stoppages in play. These extended interruptions can add several minutes to the overall duration of the game, making the total playing time closer to two hours. In fact, studies have shown that the average game lasts around 2 hours and 5 minutes, with an additional 10-15 minutes allocated for halftime, timeouts, and other stoppages. It's worth noting that some games may even extend beyond three hours if there are multiple ejections or a prolonged injury timeout.
