Sports betting taps into the passion of many fans for their favorite teams and athletes. It can also enliven even boring or one-sided contests when handicapping systems offer odds and point spreads. However, it’s important to understand the risks before placing a wager.

Gambling on athletic competitions is usually conducted through bookmakers, known as “bookies” in the United States, or via casinos, online gambling operations and other entities. Some of these operate legally, while others may be illegitimate or unregulated.

The popularity of sports betting grew in the 1970s, but it was legalized nationwide only in Nevada in 1992 after Congress enacted PASPA (Professional and Amateur Sports Protection Act). This restriction led to illegal bookies and underground operations, which thrived even after the Supreme Court struck down the ban in 2018 and opened the door for states to pass their own laws.

Casinos have been quick to jump on the bandwagon and offer sports betting, including some that have signed partnerships with major online casino malaysia bookmakers. The NHL, for example, became the first major professional league to introduce a team in Nevada with the Vegas Golden Knights, and has since signed sponsorship agreements with both William Hill and MGM Resorts International.

While the majority of sports bets are placed on individual games, some bettors place their wagers on a combination of events called parlays or props. In Las Vegas, for example, casino sportsbooks often offer a variety of these, from “simple” bets on the game’s winner or total points to more complex combinations. The rules and details vary by casino, so be sure to check them carefully. Many of these bets feature a house-banked pool that grows larger if no one hits them, and can result in large payouts.
