Do not collapse these categories
- Online casino: slots and casino-style table games offered over the internet.
- Sports betting: wagers on sporting events; authorization does not automatically include casino games.
- Online poker: peer-to-peer poker can be licensed without a broader casino market.
- Offshore and sweepstakes sites: availability is not the same as state authorization or consumer protection.
Sports betting and sweepstakes in Montana
- Sports betting: Legal at authorized retail locations only; statewide mobile wagering is not offered. Sports Bet Montana wagering runs through the state lottery, but the app only functions on the physical premises of licensed retail locations; it is not a statewide mobile product. See licensed sportsbooks.
- Sweepstakes casinos: Banned or blocked in effect. Senate Bill 555, signed by Governor Gianforte May 12, 2025, became the first explicit statewide sweepstakes-casino ban in the country, effective October 1, 2025. Read the sweeps guide.
How to verify before playing
- Start with the state regulator, not an operator's footer or an affiliate review.
- Match the exact website or app name to the approved operator list.
- Confirm age, physical-location and self-exclusion rules.
- Read the bonus wagering, withdrawal and maximum-bet terms before depositing.
