Three products that look the same
Open three apps on an American phone. Each shows slot reels, a virtual balance and a shop. In the first, the balance can never become money; you buy chips to keep playing and that is the whole transaction. In the second, you buy one currency and are given a second one free, and the second one can be redeemed for cash prizes. In the third, you deposit dollars, play with dollars and withdraw dollars, and the app only works in a handful of states.
The first is social casino. The second is a sweepstakes casino. The third is licensed real-money iGaming. The games are frequently identical, sometimes from the same supplier. The difference is what the balance is, and on that difference rests a segment that the analysts Eilers & Krejcik projected would generate $11 billion in 2025 in the United States, an industry association, a run of state bans, a wave of lawsuits and the most contested question in American gambling regulation after prediction markets.
This course is about the second model, and it starts by placing it between the other two.
Social casino: play, never pay out
Social casino grew out of Facebook games around the turn of the 2010s: DoubleDown Casino, one of the first, launched on Facebook in April 2010. A player receives a free balance of virtual coins, plays slots, bingo or poker with them, and can buy more coins when they run out. Coins have no cash value, cannot be withdrawn and cannot be transferred. The business model is the mobile-games model: a small minority of players spend (DoubleDown reported that in 2024 an average of 6.7% of its monthly social casino players made a purchase in the month), a very small minority spend heavily, and the product is tuned to convert and retain them.
Legally, social casino has been treated as a game, not gambling, in almost every jurisdiction, because the player cannot win anything of value. That position has been challenged in court, notably in Washington state, where the Ninth Circuit federal appeals court held in 2018, in Kater v. Churchill Downs, that virtual chips that extend play were a "thing of value" under the state's unusually broad gambling statute, which covers any credit involving "a privilege of playing at a game or scheme without charge", and operators settled class actions for large sums: $155 million in the Big Fish Casino case and $415 million in the DoubleDown Casino case. Elsewhere the position has held, and social casino remains a substantial, mature and mostly uncontroversial segment, much of it owned, at one time or another, by public companies from the land-based industry: the casino and racing group Churchill Downs sold Big Fish Games, the owner of Big Fish Casino, to the slot maker Aristocrat in January 2018, and the slot maker IGT owned DoubleDown Casino until 2017.
Its relevance here is that it built the audience, the content library, the monetisation playbook and the supplier relationships that sweepstakes casino then used.
Sweepstakes casino: two currencies, one of which pays
A sweepstakes casino also gives the player a free balance of virtual coins, usually called gold coins, and also sells more of them. What it adds is a second currency, usually called sweeps coins, that the player receives free as a bonus when buying gold coins, free through daily logins and promotions, and free on request by post. Sweeps coins are played on the same games. Winnings in sweeps coins can be redeemed, once a playthrough requirement is met, for cash prizes at a fixed rate, typically one sweeps coin to one dollar, and New York's attorney general found that buyers of gold coins received approximately one sweeps coin for every dollar spent.
The player experience is a real-money casino with an extra step. The legal claim is that it is not a casino at all but a promotional sweepstakes, of the kind that fast-food chains and soft-drink companies have run for decades, attached to the sale of a product, gold coins, that has no cash value. Lesson three takes that claim apart. For now the essential point is that the model was designed by lawyers to fall outside the definition of gambling, and that it has operated at scale, in most American states, for more than a decade on that basis.
The model's leading operator was an Australian company, VGW, whose Chumba Casino began serving New Yorkers in 2012 and whose brands became the largest in the segment, and the model was copied widely in the 2020s, while only a few states had legalised the real-money version. By 2025 one industry count put the number of sweepstakes casino sites serving American players above 140, with VGW's share down from well over 90% to roughly half, plus sweepstakes sportsbooks and poker rooms built on the same mechanics.
Real-money iGaming: licensed, taxed, limited
Licensed online casino is live in seven American states at the time of writing, Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island and West Virginia, with an eighth, Maine, authorised in January 2026 but not yet launched. It comes with high tax rates, state-by-state licences, mandatory responsible gambling controls, a minimum age of 21 and geofencing to the licensing state. It is the product the sweepstakes model imitates, and its slow spread is the reason the sweepstakes model exists. A resident of Texas, Florida or Georgia cannot play a licensed online slot; a sweepstakes casino will serve them today, and the largest operator still offers its sweepstakes play there. California was in the same position until a law signed in October 2025 made it unlawful to offer an online sweepstakes game in the state, and that operator now offers Californians only its free-to-play coins.
From the licensed industry's point of view the sweepstakes casino is a competitor offering the same product without the licence, the tax, the age limit or the obligations. From the sweepstakes operator's point of view the licensed industry is trying to use the state to close a market it has failed to open legally. Both descriptions are accurate, and the political fight between them is the subject of lesson three and lesson seven.
Why the segment grew
Four things drove the growth of sweepstakes casino after 2020.
Geography. Forty-three states have no live licensed online casino, and Maine's 2026 law was the first new authorisation since Rhode Island's in 2023. The sweepstakes model addressed all of them, and it had most room to grow where the licensed product did not exist.
Marketing freedom. Licensed operators face advertising restrictions and cannot market in states where they are not licensed. Sweepstakes operators advertised nationally, on television, through influencers and through affiliates who earned commissions on a product they could promote in every state.
Payments. Buying gold coins was, on the card network's books, buying a digital good. Card processing that could be declined for a gambling merchant code was approved for a games merchant. Visa's current rules put "games of chance to win prizes of monetary value" in the gambling code, 7995, and exclude games of chance from the digital games code, 5816. Lesson six covers how that changed.
Content. The supplier base that had grown up serving social casino and regulated markets was willing, for a time, to serve sweepstakes operators too, so the product could match a licensed casino game for game. Lesson five covers the suppliers' retreat.
Why it became a fight
The segment operated for a decade with little attention. Three things changed. Its scale became visible, and with it the tax that states were not collecting. Licensed operators, tribal gaming and the state lotteries, all of which lose customers to it, organised against it. And a number of operators pushed the model past its legal design: aggressive marketing of the cash prizes, minimal age checks, sports and poker products with no promotional pretence. In 2025 five states, California, Connecticut, Montana, New Jersey and New York, passed bans; attorneys general and gaming regulators in others sent cease-and-desist letters, New York's attorney general to 26 platforms before its ban and Tennessee's to 38; class actions alleging illegal gambling were filed against the largest brands, VGW among them; and California's law extended liability to payment processors, geolocation providers, content suppliers and media affiliates that knowingly support an online sweepstakes game. In September 2026 VGW agreed to pay New York $8 million.
The industry's response was to form a trade association, the Social and Promotional Gaming Association, launched in September 2024, publish a code of conduct built on age verification limiting purchases to over-18s, identity and location checks and anti-money-laundering policies, and argue for clear regulation of social sweepstakes games, pointing to age verification and other player protections, rather than bans. That is the argument of the moment, and lesson seven examines it.
What this course covers
Lesson two explains the dual-currency model in the detail needed to run one or assess one: the two currencies, the free entry route, the playthrough, the redemption. Lesson three is the legal theory and where it breaks: the three elements of gambling, the promotional sweepstakes exemption, the state responses and the litigation. Lesson four is the economics: who pays, how much, what it costs to acquire them and what the margin looks like against a licensed casino. Lesson five is product and content: the games, the suppliers who serve the segment and the ones who left. Lesson six is compliance in a grey market: age, identity, geofencing, money laundering, responsible gambling, payments and advertising. Lesson seven is strategy: for an operator deciding whether to convert, exit or fight; for a supplier or affiliate weighing exposure; and for a regulator choosing between prohibition and licensing.
The course does not take a side on whether the model is lawful. That is being decided state by state, and the answer is different in Montana, which banned the model by statute in 2025, from Texas, where the largest operator still offers it. What it does insist on is precision: the model works because of a legal design, and a professional who cannot describe that design cannot assess where it holds and where it fails.
