In basketball, a game is divided into four periods. Each period typically lasts 12 minutes in the NBA or 10 minutes in international play. The game is split into two halves, with a halftime break in between the 2nd and 3rd periods. If the score is tied at the end, overtime periods are played to determine the winner. These periods help structure the flow of the game.
