Washington is a state with an advanced tribal casino gaming industry, cruise casinos, a state lottery and a range of charitable gaming options. A network of horse racing betting venues exists with off-track betting options on simulcast horse races.
Daily Fantasy Sports (DFS) are curiously prohibited, whilst horse racing betting and games of skill the sole legal online gaming options.
Controversially, Washington Governor Jay Inslee signed a sports betting law into effect in March 2020 that limited sports wagers to tribal land. An emergency clause was inserted into the bill to bypass the required voter referendum, which has caused a stir because voters wanted to expand sports betting beyond tribal lands. For the meantime, you can only bet in person and on a mobile device while at a tribal casino.
