Sports Betting in Washington, Oregon, and Montana

Sports betting is technically legal in Washington, Oregon, and Montana, but each state has significant restrictions placed on the regulated sports betting market, which makes it difficult to place regulated sports bets in each state.

In Washington sports betting is legal, but all bets (both online and in-person) must occur on federally recognized tribal lands. There are currently over 15 tribal casinos taking bets within the state.

In Oregon sports betting is also legal, but DraftKings holds a monopoly over all online sports betting in the state. The Oregon Lottery initially had the only online betting app in the state, but DraftKings took over the online sports betting market in 2022 and is currently the only regulated online sportsbook available to Oregon residents. There are also a few in-person sportsbooks at tribal casinos throughout the state.

Montana is similar to Oregon in that sports betting is legal, but all regulated online betting must be done through the Montana Lottery website. Montana is also more restricted than Oregon in that all sports betting must be done in-person at a Sports Bet Montana location.

Washington, Oregon, and Montana residents do also have the option to place bets online through offshore betting sites that are licensed and regulated outside of the USA, while accepting American bettors. checks this box as an offshore sportsbook licensed and regulated in Curacao, while accepting US bettors.

NBA Betting Options

The three most popular betting markets for NBA games are the spread, win (money line), and total. Below I will use a Celtics vs 76ers regular season game as an example to explain these three popular NBA game wagers.

Point Spread

With a point spread bet the favorite must win by more than the spread amount, while the underdog must either win the game outright or lose by fewer points than the spread.

In the above example the Boston Celtics are 2.5 point favorites (-2.5). Spread bets on the Celtics -2.5 would win if Boston wins the game by 3 or more points. Spread bets on the 76ers +2.5 would win if Philly wins the game outright or loses by 2 or fewer points.

Win (Money Line)

A money line bet is simply a wager on which team will win the game. The risk vs reward of the bet is determined by the odds.

In the above example the Celtics are -145 favorites. This means every $145 wagered on the Celtics would win $100 if the earn the victory. The 76ers are +125 underdogs, which means every $100 risked on the 76ers would win $125 if they won the game.


A total is an over/under wager on the amount of points scored in the game. The oddsmaker sets a total and you can bet on whether the number of points scored by both teams combined will be over or under that amount.

In the above example the over/under is set at 227.5 points. Over bets would win if 228 or more points are scored in the game, while under bets would win if 227 or fewer points are scored.
