Missouri Sweepstakes Casinos

Missouri is one of the most open sweepstakes casino markets in the country, with every major brand active in the state. Equally importantly, the legislature has not considered a bill to ban sweepstakes casino sites, and local officials have not targeted the industry for a crackdown (which has happened in other states).

The most prominent sweepstakes casinos in Missouri include:

• Casino.click Online Casino
• WOW Vegas Online Casino
• Stake.us Online Casino
• Ace.com Online Casino

For those unfamiliar with the concept, sweepstakes casinos operate on a “no purchase necessary” model to avoid classification as illegal online gambling in Missouri.

In short, you can get Sweeps Coins (SCs) for free by participating in promotions, as bonuses when buying Gold Coins (GCs), and through sending requests by mail. When you have a balance of SCS, you can use them to play casino-style games and win additional SCs. Any SCs you win while playing are redeemable for cash prizes, usually at a 1:1 ratio for dollars.

For example, if you play blackjack online using SCs and win 20 more SCs, you can redeem your winnings for $20 in real money. You can also play online slots, roulette, and other table games using SCs for chances to win money.

Are Sweepstakes Casinos Legal in Missouri?

Sweepstakes casinos operate in a legal gray area under Missouri law, but it would be fair to call them “de facto legal” because of three facts:

1. No Missouri statute bans sweepstakes casinos.
2. The legislature has never considered a bill to ban sweepstakes casinos in Missouri.
3. The Missouri Gaming Commission has never asserted jurisdiction over the model or tried to close them by leveraging existing state law.

Operators contend their games are legal because free participation removes the element of consideration from Missouri’s gambling definition under MO Rev Stat § 572.010.

That said, there are some caveats worth understanding:

1. “Not banned” does not equal “legal.”

Missouri law does not explicitly ban sweepstakes casinos, but it also doesn’t authorize them. The lack of specificity hasn’t stopped authorities in other states from using existing law to force sweepstakes casinos out.

Missouri officials haven’t targeted sweepstakes casinos to date, but a change in enforcement posture could easily change the calculus for operators and result in some exiting the market.

2. Sweepstakes casinos are unregulated

The legal gray area that sweepstakes casinos occupy means there is no government oversight. Missouri sweepstakes casinos are unregulated, so there’s no agency vetting operators, auditing their financials, testing their games for fairness, or stepping in to resolve operator-player disputes. That regulatory void is why BettingUSA only recommends established brands with long track records.

3. Missouri’s enforcement posture could change

Missouri’s legal climate has become increasingly uncertain. In April 2026, the Office of the Attorney General pressured Torch Electronics (the state’s largest distributor of unregulated slot-style machines) into suspending all Missouri operations under the threat of criminal prosecution.

Announcing the shutdown, Hanaway declared that “there has never been a gray market.” That campaign targeted physical machines, so it doesn’t necessarily apply directly to sweepstakes casinos.

Still, an Attorney General willing to dismantle a politically connected quasi-gambling operation overnight is worth keeping in mind. It wouldn’t be a big leap for the AG’s office to pivot from targeting physical machines to targeting online sweepstakes games.

Will Missouri Legalize Online Casinos?

Legalization is possible but unlikely within the next few years. Missouri is a unique case because its likeliest path to legalization does not run through the legislature passing a bill that would either legalize online casino apps or initiate a constitutional referendum.

Instead, Missouri’s best hope is an industry-funded ballot initiative. However, the sports betting campaign that succeeded on that path also created the strongest argument against running another one soon.

Here’s why it will likely be a multi-year wait before the first legal and licensed Missouri online casinos launch.

A Constitutional Referendum is Likely Necessary

Legalizing online casinos in Missouri almost certainly requires a constitutional amendment approved by voters. Article III, Section 39(e) of the Missouri Constitution authorizes games of chance only on excursion gambling boats and floating facilities on the Mississippi and Missouri Rivers.

Although online gambling does not fit neatly into that exact framework, any bill that legalizes online casinos without a constitutional amendment would invite legal challenges that it may not survive.

Missouri’s own sports betting history shows how the state resolves the question in practice. Lawmakers filed sports betting bills for six consecutive sessions without passing one. Legal Missouri online sportsbooks arrived only after a citizen-initiated constitutional amendment that voters narrowly approved in 2024.

However, some Missouri lawmakers have proposed legal workarounds. For example, a 2024 bill proposed authorizing online sports betting by considering all online wagers as occurring on a gambling riverboat regardless of the bettor’s location. Past online casino proposals have leaned on that same legal fiction.

The construct has never been tested in Missouri courts, and the fact that sports betting ultimately required a constitutional amendment suggests that the industry did not trust it to hold.

The Amendment 2 Blueprint for Online Casinos in Missouri

Missouri’s sports betting saga is likely the template any online casino effort would follow. The legislature debated sports betting bills for years and passed none of them.

The industry eventually stopped waiting. DraftKings and FanDuel bankrolled a constitutional initiative petition campaign that culminated in Amendment 2 appearing on the November 2024 ballot without the legislature’s involvement. It passed by fewer than 2,700 votes out of nearly 3 million cast.

A similar approach could work for Missouri online casinos. If the major online gambling brands decide Missouri is worth the campaign cost, they have a proven template to follow. The open question is whether the first trip through that process poisoned the well for a second.

The Tax Problem That Will Haunt the Next Campaign

Online sportsbook brands pitched Amendment 2 to voters as a windfall for education in Missouri, but the early returns were anything but that. The gap between what the Amendment 2 campaign promised and what it delivered is the biggest new obstacle any future online casino initiative will face.

The sports betting amendment set a 10% tax on adjusted gross revenue but allowed operators to deduct promotional credits  before calculating what they owe.

Missourians wagered $543 million in the state’s first full month of legal online sports betting (December 2025), while the state collected roughly $521,000 in tax revenue. Over the first four months, total handle topped $1.5 billion, while tax collections reached only about $4 million.

Lawmakers noticed and briefly considered (but dropped) a bill that would have raised the tax rate and capped promotional deductions. The lesson for Missouri online casino watchers is that an operator-drafted amendment would include operator-drafted tax terms. Expect opponents of any future Missouri online casinos initiative to lead with the sports betting numbers.

Missouri Voters Have Shown Mixed Interest in Gambling Expansion

The success of Amendment 2 may have been encouraging for online casino proponents, but the result was hardly a mandate.

Amendment 2 passed with just 50.05% of the vote. On the same ballot, Missouri voters rejected Amendment 5, which would have permitted one additional casino license on the Osage River near the Lake of the Ozarks.

Amendment 2’s narrow passage and Amendment 5’s defeat on the same ballot show that Missourians do not support unlimited gambling expansion. To repeat Amendment 2’s blueprint, online gambling brands like BetMGM Casino, FanDuel Casino, and Caesars Palace Casino would have to spend significant sums on a campaign with a very real chance of defeat, all to reach a single state with a population of 6.27 million people.

Legalizing Missouri Online Casinos Without an Amendment

Although legalization doesn’t appear imminent, there are some reasons for proponents to be hopeful.

For one, most of the challenges discussed above deal with the political concerns around a constitutional amendment. Although the amendment route is the safest from future legal challenges, lawmakers have considered legislation crafted to avoid a referendum.

In 2022, lawmakers considered a bill (HB 2144) that would have authorized “interactive gaming” through Missouri’s licensed riverboat casinos. The bill attempted to deal with the constitutional question by mandating a secondary server at every licensee’s physical casino and declaring every wager to have taken place at that location.

Additionally, Missouri is well-prepared to regulate online casinos. The Missouri Gaming Commission already regulates commercial casinos, online sportsbooks, and daily fantasy sports operators.

As a result, the Commission has experience with licensing investigations, geolocation technology, internal controls, operator audits, responsible gambling, and more.

Potential Missouri Online Casino Market

Missouri is already one of the nation’s larger gambling markets, and its sports betting numbers indicate that residents have an appetite for online access.

According to the Missouri Gaming Commission’s 2025 annual report, the state’s land-based casinos generated approximately $1.91 billion in adjusted gross revenue and paid $401.8 million in gaming taxes during the 2025 fiscal year.

If nothing else, those numbers demonstrate strong demand for slots and table games, and online casinos would reach residents statewide. Although Missouri online casinos would likely cannibalize some revenue from riverboat operations, experience in other states clearly demonstrates that statewide online access creates significant added revenue.

The tax structure, licensing requirements, and market access rules would play important roles in determining how much revenue online casinos would generate at market maturity.

Missouri’s approach to taxing online casinos could be especially contentious, with land-based casinos taxed at 21%, while the failed 2022 proposal called for a 12% tax.

Even without naming a specific, speculative number, Missouri has the population, casino participation, and major metropolitan markets to support a substantial online casino industry.
