"Offshore casino" gets used for very different things, and the difference matters to anyone in the US. This guide sets out what the term means, what state regulators say about offshore sites, how sweepstakes casinos work, and what neither model guarantees. It doesn't recommend any offshore site.
| Model | How it works | Who oversees it |
|---|---|---|
| Offshore real-money casino | You deposit money and bet it on casino games or sports. | No US state. Regulators treat these sites as illegal operators. |
| State-licensed online casino | Real-money casino games, only in states that license them. | That state's gaming regulator. |
| Sweepstakes casino | Two currencies: Gold Coins for play only, and Sweeps Coins, a promotional entry that may be redeemed for prizes where the operator allows it. A free way to get Sweeps Coins is offered. | Not licensed as gambling. Each state decides whether the model is allowed, and some restrict or ban it. |
| Social casino without prizes | Virtual coins only. Nothing can be redeemed. | Consumer and app-store rules. |
What "offshore casino" means
An offshore casino is a gambling site that takes real-money bets from US players without a license from the state where the player is. The company may hold a license somewhere else, or none at all, but no US state regulator supervises it. Where a company is incorporated isn't the point. The point is that it offers real-money gambling into a state that hasn't licensed it.
That's why "best offshore casino" is the wrong question for a US player. A ranking can compare bonuses and payout speed, but it can't change the fact that the operator sits outside every state's rules.
What state regulators say
On October 8, 2026 the Michigan Gaming Control Board (MGCB) said it had sent cease-and-desist letters to 32 offshore operators "found to be illegally offering online casino games, sweepstakes-style games, and sports betting to Michigan residents." The board pointed to a risk that's easy to miss. Licensed Michigan operators must honor the state's responsible gaming database, which lets people ban themselves from online gambling. Offshore operators don't have to, so a person who has self-excluded can still open an account and deposit on an unlicensed site.
The board's executive director, Henry Williams, put it plainly: "Offshore sites don't respect it."
The same regulator has also acted against sweepstakes-style operators. In January 2024 the MGCB announced cease-and-desist letters to three companies, two of them sweepstakes operators, for offering online games in Michigan without a state license. So the sweepstakes label on its own doesn't settle whether a site may operate in a given state.
How big the illegal market is
The American Gaming Association, the trade group for licensed US casino operators, estimated in August 2025 that illegal online slot and table sites take $18.6 billion in revenue a year, and that illegal operators hold 66 percent of the US online casino market, down from 75 percent in 2022. These are an industry association's estimates, built on a survey of nearly 2,500 adults and public market data, not official government figures.
How sweepstakes casinos differ
A sweepstakes casino runs on promotional sweepstakes rules rather than a gambling license. You play with Gold Coins, which have no cash value. Sweeps Coins come free with sign-up offers and daily bonuses, by mail-in request, or as a bonus with an optional Gold Coin purchase, and they can be redeemed for prizes once you meet the operator's rules. The free route matters, because a sweepstakes can't require a purchase to enter.
Three things are worth knowing before you rely on that model:
- Availability depends on your state. Some states restrict or ban sweepstakes casinos, and the list changes. Check our state restrictions guide and the operator's own excluded-state list.
- Redemptions need identity checks. Expect to verify your identity and address before a first prize redemption.
- The official rules decide. Each operator publishes sweepstakes rules covering eligibility, the free entry method, minimum redemptions and how long they take. Read them before you buy anything.
Before you sign up anywhere
- Check whether your state licenses real-money online casinos, and if it does, confirm the site on your state regulator's list.
- For a sweepstakes casino, check your state on our state restrictions guide and in the operator's official rules.
- Find the free entry method in the rules. If you can't find one, treat that as a warning sign.
- Set limits before you play, and know where the self-exclusion and limit tools are.

FAQ
Are offshore casinos legal for US players?
Offshore sites that take real-money bets from US players aren't licensed by any US state, and regulators such as Michigan's treat them as illegal operators. Whether a player can face consequences depends on state law. The practical risks are the same everywhere: no state regulator to complain to, and no duty to honor state self-exclusion.
Is a sweepstakes casino the same as an offshore casino?
No. A sweepstakes casino uses a promotional model with a free way to enter, not real-money betting. But it isn't automatically legal everywhere either: states decide, and some restrict or ban the model. Check our state restrictions guide.
Can I win real money at a sweepstakes casino?
Sweeps Coins can be redeemed for prizes, often cash, where the operator allows it and once you meet its redemption rules and identity checks. Gold Coins can never be redeemed.
