Are Sweepstakes Casinos Legal in Montana?
No. Sweepstakes casinos are illegal in Montana.
Governor Greg Gianforte signed SB 555 on May 12, 2025. The law took effect on October 1, 2025, and amended Montana’s existing gambling code instead of creating a separate sweepstakes chapter.
The statute does not need to use the word “sweepstakes.” MCA 23-5-112 now states that internet gambling includes online casinos “by whatever name known.” It covers platforms that accept wagers and issue prizes using any form of currency.
Are Crypto Casinos and Contest Platforms Legal in Montana?
Offshore crypto casinos are not lawful alternatives in Montana. SB 555 covers online casinos using any form of currency and specifically reaches sites operated through offshore sources.
The same caution applies to CardCrush and other contest platforms. A different label does not determine legality. Any service involving casino-style wagering and prizes must be assessed under Montana’s broad internet gambling definition.
Crush Cards is an independent review site, not a Montana regulator. Coverage of a contest platform does not establish that the product is permitted in the state.
Because Montana criminalizes solicitation of illegal gambling, this page does not provide links or calls to action for offshore casinos, crypto casinos, or prize-based contest sites.
Legal Gambling Options in Montana
Sports Bet Montana
Sports Bet Montana is the state’s authorized sportsbook. Players can prepare wagers through its website or app, but a wager can only be placed while physically present at an authorized Sports Bet Montana location.
It is not statewide mobile betting from home. The service uses location controls to confirm that the player is at a licensed premises.
Montana Lottery
The Montana Lottery offers scratch tickets, state draw games, and multistate games such as Powerball and Mega Millions. Tickets are sold through authorized retailers, with selected account and information functions available online.
Tribal Gaming
Tribal gaming operates under federal law and state-tribal compacts. Available games, wagering limits, and age requirements depend on the compact and individual property.
SB 555 preserves the statutory exception for qualifying Class II and Class III gaming conducted on Indian lands under federal requirements.
Licensed Local Gambling
Montana permits approved video gambling machines, poker, sports pools, raffles, and other limited activities under specific licenses and rules. The Montana Department of Justice maintains records of licensed gambling businesses and machines.
These local options do not create a license for online casino gaming.
What SB 555 Changed
SB 555 amended four sections of the Montana Code Annotated: MCA 23-5-112, 23-5-123, 23-5-154, and 23-5-162.
| Provision | What it does |
|---|---|
| MCA 23-5-112 | Defines online casinos using wagers and prizes in any form of currency as prohibited internet gambling |
| MCA 23-5-123 | Directs gambling-related fines and penalties to the Montana Department of Justice |
| MCA 23-5-154 | Prohibits knowingly advertising or soliciting participation in illegal gambling |
| MCA 23-5-162 | Applies felony liability to knowingly operating an illegal internet gambling site within Montana |
MCA 23-5-151 remains Montana’s general rule that all public gambling is prohibited unless a statute specifically authorizes it. The online-casino definition itself is found in MCA 23-5-112.
Penalties and Enforcement
MCA 23-5-162 applies felony liability to someone who purposely or knowingly operates an illegal internet gambling site within Montana, including a site operated through an offshore source.
Each violation can carry:
- A fine of up to $50,000.
- Imprisonment for up to 10 years.
- Both a fine and imprisonment.
- Revocation of Montana gambling licenses and permanent ineligibility for another license.
Advertising is addressed separately. MCA 23-5-154 makes it a crime to knowingly advertise or solicit participation in an illegal gambling enterprise. The applicable penalty depends on the conduct and related provisions. It should not be described as automatically carrying the same felony sentence as operating the site.
The Montana Department of Justice Gambling Control Division oversees enforcement of most state gambling laws. The Montana Lottery, sports wagering, and horse racing operate through separate regulatory structures.
Do Individual Players Face Liability?
SB 555 directly strengthens the rules for illegal operators and solicitation. It does not create an express exemption protecting individual players.
Montana’s wider gambling code includes misdemeanor and felony provisions that can apply to knowingly participating in prohibited conduct or obtaining value through an illegal gambling enterprise. The exact exposure depends on the facts, amount involved, and statute used.
Using a VPN does not change the player’s physical location or legal position. It can also violate operator terms and lead to a frozen account or rejected redemption.
Which Operators Left Montana?
Major national platforms began restricting Montana before the October 2025 effective date. Operators that have listed Montana as restricted include Chumba Casino, LuckyLand Slots, McLuck, Pulsz, Mega Bonanza, PlayFame, Funrize, and NoLimitCoins.
Restricted-state lists can change. However, an operator unexpectedly accepting a Montana registration would not override SB 555 or amount to state approval.
Anyone with an old account should check the operator’s closure notices and contact official customer support about remaining records. Do not make another purchase to unlock a balance or use false location information to bypass a restriction.

The Bottom Line
Sweepstakes casinos are illegal in Montana under SB 555. The law covers online casinos by any name when they accept wagers and issue prizes using currency. Major operators have responded by excluding the state.
The felony penalties of up to $50,000 and 10 years apply to knowingly operating an illegal internet gambling site. Advertising and solicitation create separate criminal exposure. Montana residents should use regulated options such as Sports Bet Montana, the state lottery, tribal gaming, or licensed local gambling.
