Montana sweepstakes casinos were once an open secret, but that changed as soon as the state signed SB 555 in May 2025. Since October 1, 2025, Montana has started treating online sweepstakes casinos as a felony-level offense, with penalties that can reach ten years. That change truely does not leave any room for confusion. So operators reacted quickly by banning Montana users or blocking them altogether.
Things have moved fast in your state. New enforcement actions, changing rules, and platforms pulling out — it’s a lot. That’s why we’re rebuilding this page right now: to make sure everything you read here is accurate, current, and actually useful to you.
While we finish that, we’re only showing the sweepstakes casinos that still accept players from Montana — and we’re also flagging the major brands that no longer do. The full legal breakdown is coming soon, and it’ll give you everything you need to play safely and stay informed.
Thanks for your patience — it’s worth getting right.
