Hockey guides: scoring, overtime and youth game length

Ice hockey plays 3 periods of 20 minutes, and the team with more goals at the end wins. The questions start after that: why an NHL game won in a shootout goes down as 3-2, why a team that loses in overtime still earns a point, and how college, international and youth leagues break a tie.

Start with hockey scoring rules, which keeps a sample game goal by goal over three periods and adds up the line score. Then go deeper where you need it: hockey overtime rules from the NHL to youth leagues, how long a youth hockey game lasts at each age, and field hockey scoring, where a goal only counts from inside the circle and a tie can end in an 8-second shootout.

Every rule here cites the governing body or league it comes from (the NHL, IIHF, NCAA, USA Hockey, Hockey Canada, NFHS, state associations and the FIH), and every app mention matches what the hockey score tracker app actually does, including what it leaves out.
