Sure, let’s begin with the basic rules.

And how many periods of play are there?
user
Well, most professional games have three 15-minute periods of play, plus a halftime that’s also 15 minutes.  If you’re watching a college game, they usually have two 15-minute periods of play, with no halftime.  Sometimes there are also overtime periods of 5-7 minutes each, and sometimes there are sudden-death overtimes, where the game ends when one team scores.  So in total, a professional game can last for up to 120 minutes of play.
