Underdogs will have positive number odds - longer odds, in betting parlance - and favorites have negative or shorter odds. These odds consist of positive or negative numbers, depending on which team is the favorite and which is the underdog. These are the most common format in the United States. They are all interchangeable, so don’t panic if you see different formats you can simply switch to the one you’re most comfortable with. Odds are represented as whole numbers (American format), decimals, or fractions. The betting odds for NHL games are the same that you might have seen elsewhere.
