How is a ice hockey match?

Every hockey game consists of three periods of 20 minutes, and separated by two intervals of 15 minutes each one. The clock counts only the time when the puck is moving, and the clock stops whenever the disc is stopped. This can happen when the referee blows for a foul, ball or puck leaves the field is noted. There is a judge who is responsible for carrying playtime. The team is entitled to a standstill period of 30 seconds per time.

If after these three times there is still drew, proceed to play an extension of five -minute sudden death, in which the first team to score a goal wins. 

In the NHL (National Hockey League) during the regular season, in overtime you play 4 on 4 (goalkeeper included), being as follows: 1 goalkeeper, 2 fenders, one in the middle and one in the end. If after this period is still in draw, the game normally go to a round of free kicks (penalty shot). In the NHL playoffs extensions 20 minute sudden death 5 would be played to 5 (goalkeeper included). In international play in qualifying an extension of 20 minutes you play a 4 v 4 (goalkeeper included), followed by a round of penalty shots launched if the parity is not broken.
