Where online casinos are legal in the US: 2025 state-by-state breakdown

As more Americans turn to their phones and laptops for casino entertainment, only a small group of states currently allow full online casino play, while others offer narrower forms of internet wagering. The landscape remains fractured, with each state setting its own rules on what is permitted, how platforms must operate, and how players are protected. Here’s a clear look at where things stand in 2025, and why this patchwork matters for consumers, policymakers and the industry.

A fragmented map of online casino legality

When it comes to online gambling in the US, the authority to permit or prohibit sits almost entirely with individual states, provided they remain within the boundaries set by federal laws around interstate betting, tribal gaming and financial transactions. The result is a mosaic of rules that can shift dramatically from one state border to the next.

As of 2025, just seven states have authorised full online casino gaming: Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island and West Virginia. Each permits digital versions of slot machines and table games, while most also allow online poker. Nevada, long a pioneer in internet gambling regulation, continues to license only online poker rather than full casino play.

The paths those states took are often very different.

• Connecticut approved online casino operations in 2021 through agreements with its two tribal nations, giving each tribe a single online brand to operate off-reservation.
• Delaware, an early adopter, placed online gaming under the state lottery’s oversight and later joined Nevada and New Jersey in an interstate poker network.
• Michigan’s 2019 law opened the market to tribal and commercial casinos alike, with regulators approving a large cohort of platform providers before launching in 2021.
• Rhode Island, newest to the list, authorised a state-run model in partnership with Bally’s and IGT, launching statewide play in March 2024.
• West Virginia, which allowed its casinos up to three branded platforms each, went live in 2020 and recently joined the interstate poker compact.

Alongside these online casino offerings, which are all tracked and reviewed by SiGMA Play US, a larger group of states has permitted internet lotteries or other limited forms of interactive gambling. Digital lottery games are now available in 13 jurisdictions. More than two dozen states allow online horse-race wagering, and 22 regulate online fantasy sports.

Sports betting has been the fastest adopter. After the Supreme Court struck down the federal ban in 2018, more than 30 states introduced legal online sportsbooks.

This uneven regulatory sprawl has led to some unusual consumer behaviour. In one widely discussed example, Nebraskans, blocked from legal online sports betting at home, were driving across the border into Iowa and parking in a cornfield purely to place wagers on their phones, making the remote field one of the state’s betting hotspots. 

Research groups found lines of cars pulling up, tapping in bets, then returning immediately to Nebraska. Similar workarounds occur nationwide: truck drivers timing their routes through states where betting is legal, and business travellers deliberately routing flights through places where sportsbooks operate.

Responsible gambling and legal considerations

The rapid spread of mobile betting and online gaming has pushed regulators to tighten oversight. According to the American Gaming Association’s latest review, responsible-gaming rules have become far more formalised since 2022. Two-thirds of commercial jurisdictions now require operators to submit detailed responsible-gaming plans, and every commercial gaming state mandates a self-exclusion programme.

Advertising rules have also stiffened across legal gambling in the US. More than 80 percent of jurisdictions restrict how gambling ads can be targeted, with some states prohibiting marketing in media where a notable portion of the audience is expected to be underage. Several states, including Massachusetts, New Jersey, Colorado and North Carolina, now require operators to use data and automated tools to spot customers showing signs of risky behaviour.

Financial protections are becoming equally common. Seventeen states restrict credit card use for gambling, while 29 require operators to provide tools for players to set limits on deposits, losses or time spent. A growing number of states, Indiana, Kentucky, North Carolina and Vermont among them, have earmarked dedicated annual funding for research and treatment of gambling harms.
