Wyoming Gambling Laws In 2026
Wyoming has a smaller gambling market than many states, but its laws allow several regulated options for residents and visitors. Legal gambling options include online sports betting, tribal casino gaming, pari-mutuel horse racing, historical horse racing machines, charitable gaming, and the state lottery. Each category is governed by its own rules, regulators, and age requirements.
This guide explains how Wyoming gambling laws work, what types of betting are legal, and where players can gamble safely within the state. It also covers tribal gaming on the Wind River Reservation, the status of online casinos and poker, sports betting rules, lottery laws, and key regulatory agencies.
Are Online Casinos Legal In WY?
The state does not regulate online casinos or apps, nor do many others, as the practice is limited to Connecticut, Delaware, Maine, Michigan, New Jersey, Pennsylvania, Rhode Island, and West Virginia. Legislators could consider web-based or mobile options in the future, but any such effort would almost certainly need to involve local tribes to get off the ground.
Offshore casino sites are not regulated by the state, but they are able to operate legally within WY because there are no laws suggesting that they cannot.
Minimum Age
Wyoming sets the legal gambling age at 18 or older for state-regulated gambling options, including casino games, pari-mutuel wagering, lottery, and online sports betting.
| Gambling Type | Legal Age |
| Tribal casinos, including slots and table games | 18+ |
| Historical horse racing machines | 18+ |
| Off-track betting and pari-mutuel wagering | 18+ |
| Lottery games | 18+ |
| Online sports betting | 18+ |
| Offshore gambling sites | Sites vary between 18 and 21 |
WY Gambling Laws
Wyoming Criminal Gambling Laws
WY generally prohibits gambling unless the activity falls under a specific legal exception. The state’s criminal gambling provisions are found in Title 6 of the Wyoming Statutes*, which covers gambling offenses, professional gambling, gambling devices, and related criminal penalties. In practice, this means gambling is illegal by default unless local law specifically authorizes it.
Gaming Commission Laws
The Wyoming Gaming Commission is the main state regulator for lawful gaming and pari-mutuel activity. Its responsibilities include oversight of online sports wagering, pari-mutuel wagering, historical horse racing, skill-based amusement games, and charitable gaming, as well as licensing, enforcement, and rulemaking.
The commission’s authority is primarily derived from Title 11, Chapter 25 of the Wyoming Statutes*, which governs pari-mutuel wagering and skill-based amusement games.
Tribal Gaming Laws
Tribal gaming in WY is governed by the federal Indian Gaming Regulatory Act, tribal law, and either a tribal-state compact or federal gaming procedures.
The Eastern Shoshone Tribe operates Class III gaming under a tribal-state compact with the state of Wyoming. The Northern Arapaho Tribe operates Class III gaming under federal Secretarial Procedures following the failure of compact negotiations with the state. Tribal casino gaming is located on the Wind River Reservation and is separate from the state’s commercial sports betting, pari-mutuel, lottery, and charitable gaming laws.
Online Casino and Poker Laws
There are currently no state-regulated real-money online casinos or online poker options. Online sports betting is legal, but casino-style internet gambling has not been authorized by local law. Offshore online casinos accept players in WY, but those sites are not regulated locally.

Mobile Gambling Laws
WY allows mobile gambling in limited, regulated forms. The clearest example is online sports betting, which is legal statewide through licensed sportsbook apps. Bettors can register, deposit, and place wagers from a mobile device as long as they are physically located inside the state and meet the state’s minimum age requirement of 18 or older.
Mobile casino gambling in Wyoming is different. Lawmakers have not yet legalized state-regulated online casinos, mobile slots, online table games, or real-money poker apps.
Mobile betting tied to legal pari-mutuel wagering may also be available through approved racing or advance-deposit wagering platforms, depending on licensing and regulatory approval. In general, mobile gambling is legal only when offered by a licensed or otherwise authorized operator.
Tribal Compacts In WY
Tribal casino gaming is centered on the Wind River Reservation, which is home to the Eastern Shoshone Tribe and the Northern Arapaho Tribe. Tribal casinos are the state’s main form of full-scale, in-person casino gambling.
Under the federal Indian Gaming Regulatory Act (IGRA), tribes may offer Class III casino gaming on Indian lands if the gaming is authorized by tribal law, located in a state that permits that type of gaming, and conducted under either a tribal-state compact or federal gaming procedures approved by the U.S. Department of the Interior.
The tribal gaming framework in WY is unusual because the two Wind River tribes do not operate under identical legal arrangements.
Why The Tribal Gaming Structure Matters
Wyoming’s tribal gaming system differs from that of many other states because it developed through both negotiation and litigation. The Eastern Shoshone Tribe’s gaming authority comes through a compact with the state, while the Northern Arapaho Tribe’s authority comes through federally issued procedures after compact negotiations failed.
For players, the practical result is that tribal casinos on the Wind River Reservation may offer Las Vegas-style casino gaming, including slot machines and table games, even though the state does not authorize commercial casinos elsewhere.
For regulators, the distinction is important. Tribal casino gaming is not regulated in the same way as WY’s online sports betting market, lottery, pari-mutuel wagering, or historical horse racing machines. Tribal casino gaming is governed by IGRA, tribal law, federal oversight, and, where applicable, the specific terms of a compact or Secretarial Procedures.
Wyoming Tribal Gaming Timeline
1988 — Indian Gaming Regulatory Act enacted
Congress passes IGRA, creating the federal framework for tribal gaming in the United States. IGRA divides gaming into classes and requires Class III casino gaming to be conducted under a tribal-state compact or, in certain cases, federal procedures.
2002 — Northern Arapaho litigation advances
A federal district court finds that the state failed to negotiate in good faith with the Northern Arapaho Tribe over Class III gaming. The decision becomes a major turning point in Wyoming tribal gaming law.
2004 — Tenth Circuit rules for the Northern Arapaho Tribe
The U.S. Court of Appeals for the Tenth Circuit rules that Wyoming must negotiate over a broader range of Class III gaming because state law permits certain forms of gambling, including broad “any game, wager or transaction” language in limited contexts.
2005 — Federal Secretarial Procedures issued for the Northern Arapaho Tribe
After compact negotiations still do not produce an agreement, the U.S. Department of the Interior issues Class III Gaming Procedures for the Northern Arapaho Tribe. This allows the tribe to operate Class III gaming without a traditional compact.
2006 — Eastern Shoshone compact signed and approved
The Eastern Shoshone Tribe and Wyoming enter into a Class III gaming compact. The compact is approved by the U.S. Department of the Interior and establishes the tribe’s legal framework for Class III gaming.
2016 — Eastern Shoshone compact replaced and extended
The Eastern Shoshone Tribe and WY enter into a second Class III gaming compact. The new compact replaces the 2006 agreement and extends the tribe’s compact framework for an additional 20 years, providing continuity through 2046.
Today, Tribal casinos remain Wyoming’s only full-scale casino gaming.
Full casino-style gambling in the state is only available through tribal gaming on the Wind River Reservation, under the Eastern Shoshone compact and the Northern Arapaho Secretarial Procedures.
Offshore
The absence of online casinos in the state has created an exclusive market for offshore gambling sites. The convenience of gambling without the need to travel attracts many local players, and they can partake without legal risk.
The sites listed in our OnlineWyomingCasinos.com casino reviews are located overseas in countries where web-based international gaming is legal. US and federal laws do not prohibit these sites, nor do they have the authority to do so.
Recent Efforts to Expand Gaming
Local lawmakers have considered several recent gaming expansion proposals, but none of them have passed.
- In 2025, HB0162 proposed legalizing interactive gaming, including online versions of casino games such as poker, blackjack, and slots, as well as other commission-approved games. The bill died in committee.
- Lawmakers also considered HB0299, which would have allowed Wyoming tribes to participate in online sports wagering, but that measure failed in the Senate Committee of the Whole.
The Legislature has continued studying historical horse racing, simulcasting, skill-based amusement games, gaming taxes, and regulatory oversight. Recent activity shows that lawmakers are open to debating gaming expansion, but the latest legislative momentum has focused more on regulation, local control, and enforcement than broad new gambling legalization.
