An NHL 3-way bet is a bet involving only the regulation portion of the NHL game. These wagers do not include any overtime or shootouts, only the three periods of the game totaling 60 minutes.
The three betting options for an NHL 3-way bet are selecting one of the two teams to be winning at the end of regulation or betting that the game will be tied at the end of regulation. You will get better odds on both teams by selecting them to win in a 3-way bet because overtime is not factored in, so there is one more possible outcome, thus improved odds on each team. 3-way bets are also great if you believe the game will be tied after regulation.
