Are real-money online casinos legal in South Dakota, and what is actually authorized after the House State Affairs Committee killed SJR 504 in February 2026?
The first ticket went down on November 1, 1989, three days short of a year after voters wrote Amendment B into the state constitution. Thirty-five years later, the Deadwood casino tax has generated $457.4 million for the state and sent $237.4 million of that straight back to the city for historic preservation. The bet ceiling rose three times along the way.
$5
Slots, poker, blackjack, three-card poker, and let it ride launch under Amendment B. To qualify for a license, each operator has to also run a non-gambling business such as a restaurant or saloon.
$100
Voters raise the ceiling after Kevin and Dan Costner condition their Midnight Star resort plans on a higher limit. The bet cap had cleared the legislature twice and been overturned at the ballot before this vote.
$1,000
The legislature raises the cap tenfold; the new ceiling takes effect in July 2012. Deadwood revenue had plateaued near $111M after 2009, the prior all-time high.
Game menu expanded
Voters approved Amendment Q 57-43 in Nov 2014. Craps, keno, and roulette arrive in Deadwood on the effective date, and tribal casinos add the same games under most-favored-nation language in their Class III compacts.
Casinos opened in November 1989 at $5 and never again looked like the small-stakes experiment voters approved. The $100 ladder step came after Kevin Costner threatened to pull his Midnight Star resort, the $1,000 step came after a decade of flat revenue, and the Amendment Q game menu came after another four years of weak post-recession growth. Each step required either a statewide referendum or a constitutional amendment, because Article III Section 25 still treats commercial gaming as the exception, not the rule.
Sixty-five percent of South Dakotans approve the constitutional amendment letting the legislature license slot machines and limited card games inside the city of Deadwood, with net proceeds dedicated to the historic restoration and preservation of the town.
Limited stakes gaming begins under SDCL Chapter 42-7B. South Dakota becomes the third state in the country to authorize commercial casinos after Nevada and New Jersey. Casino revenue more than doubles from $25.6 million in 1990 to $56.6 million in 1991.
Voters approve the expansion 57-43. The new games arrive in Deadwood on July 1, 2015, and tribal casinos with Class III compacts add them the same day under the most-favored-nation language in their agreements.
239,620 yes to 170,191 no, a 58-42 win. The amendment only authorizes sports wagering inside Deadwood; tribal casinos can mirror it through their existing IGRA compacts.
Gov. Kristi Noem signed SB 44 in March, the law took effect July 1, and the Commission on Gaming approved final rules in August. Tin Lizzie Gaming Resort hosts the ceremonial first ticket on the eve of the 2021 NFL season.
Sen. Casey Crabtree and Rep. Greg Jamison's resolution to put statewide mobile sports betting on the November 2026 ballot, with 90 percent of tax revenue earmarked for property tax relief, clears the Senate 23-10. The House State Affairs Committee then defeats it 7-6, leaving online wagering of any kind off the next ballot.
Total Deadwood gaming taxes rose 17 percent over the decade ending in 2024, from $14.7 million to $18.9 million. The city's share stayed flat at about $7.1 million the whole time, because a cap on the residual tier sent the growth to the state general fund. Senate Bill 102 in 2026 rewrote that formula. Gov. Larry Rhoden signed it on March 19, 2026 and the new split takes effect July 1, 2026.
State economist Derek Johnson warned the legislature that the long-term effect of SB 102 is slower growth in general-fund gaming revenue. Backers led by the Deadwood delegation and the Bureau of Finance and Management said that argument cuts the wrong way. The reason gaming revenue exists at all is the Amendment B promise that casino dollars would rebuild a town the state had allowed to crumble, and that promise had stopped tracking inflation a long time ago.
Most coverage of South Dakota gambling starts in Deadwood. The money tells a different story. State video lottery terminals in age-21 bars and small casinos outside Deadwood handled $1.17 billion in fiscal year 2024 and sent $163 million to the state. Deadwood's 9 percent tax sent $19.3 million that same year. Video lottery is roughly eight times the commercial-casino business from the state's point of view.
The South Dakota Lottery has transferred over $3.9 billion to the state since the agency launched in 1987. That total includes draw games, scratch tickets, and video lottery, with VLT contributing the bulk of the recent annual flow. The political consequence is that the legislators most willing to expand commercial gaming sit in districts dependent on VLT route operators, and the agency most exposed to any iGaming bill is the SD Lottery, not the Commission on Gaming.

South Dakota has nine federally recognized tribes. Eight of them run casinos under Class III compacts signed with the state and approved by the U.S. Department of the Interior. The eleven properties spread across nine counties and cover every quadrant of the state. Dakota Sioux Casino north of Watertown opened the first tribal sportsbook on April 27, 2022, seven months after Deadwood's first legal sports bet.

The Class III compacts each tribe signed with the state include a most-favored-nation clause, which is why Deadwood’s Amendment Q expansion in 2015 also gave tribal casinos craps, keno, and roulette. The same clause spread sports betting to tribal sportsbooks in 2022 once Deadwood had a legal book under SB 44. Mobile wagering still ends at the property line on either side of the line.
South Dakota built its gambling map by adding constitutional carve-outs one at a time, and online casinos have never been one of them. Article III Section 25 forbids the legislature from authorizing games of chance, lotteries, or gift enterprises, and every legal form in the state sits inside an exception voters wrote into that section. The SD Lottery came in by amendment in November 1986. Deadwood limited gaming arrived in November 1988 with Amendment B, which passed 65 percent and let the legislature license slot machines and card games inside Deadwood's pre-1880s downtown footprint, with proceeds funding historic preservation. Casinos opened on November 1, 1989. Amendment Q expanded the games to include keno, craps, and roulette in 2014, effective July 1, 2015. The full Deadwood framework lives in SDCL Chapter 42-7B. The South Dakota Commission on Gaming, a five-member board appointed by the governor and attached to the Department of Revenue, enforces it.
Online casinos run into two walls. SDCL Chapter 22-25A directly criminalizes engaging in or facilitating gambling using the internet. The constitution offers no online-casino exception, so authorizing one would require a statewide vote. The Commission on Gaming reinforced that position in an August 2025 public alert warning South Dakotans that the offshore sites and sweepstakes-model casinos advertising in the state are not licensed and carry no consumer protections. Sports betting followed the slower path: 58 percent of voters passed a new Amendment B in November 2020 (239,620 yes to 170,191 no), the legislature enacted SB 44 in early 2021, Gov. Kristi Noem signed it in March, and the first bet went down at Deadwood's Tin Lizzie Gaming Resort on September 9, 2021. The same compacts let tribal casinos open sportsbooks shortly after; Dakota Sioux Casino north of Watertown launched on April 27, 2022. Mobile sports betting beyond casino property has failed in three straight attempts: SJR 502 cleared the Senate 18-17 in 2022 before dying in House State Affairs 10-3, and SJR 504 passed the Senate 23-10 on February 11, 2026 only to be killed in the same House committee 7-6 weeks later.
Sen. Casey Crabtree of Madison and Rep. Greg Jamison of Sioux Falls drafted SJR 504 as a property-tax-relief vehicle wrapped around a sports-betting expansion. Mobile wagering would have run statewide, but every platform would have had to partner with a licensed Deadwood casino and host its servers inside the city. The Senate sent the question toward the November 2026 ballot 23-10. The House State Affairs Committee killed it 7-6 a week later.
Opponents on the House committee used the handle math against the bill. South Dakota sports betting took $2.65M in 2021 (partial year), $7.19M in 2022, $9.03M in 2023, $9.24M in 2024, and $10.80M in 2025. A 9 percent tax on those revenues, with 90 percent routed to property tax relief, would not move the typical homeowner’s bill more than a few dollars a year even if mobile betting triples the market. Sponsors framed the question as a constitutional vote on tax relief; opponents framed it as the camel’s nose for iGaming. Seven votes carried the day.

About 22 limited-stakes casinos operate inside Deadwood, ranging from small Main Street rooms to full resorts like Cadillac Jack's, Deadwood Mountain Grand, Tin Lizzie, and the Hard Rock Hotel & Casino that opened in 2024. The Commission on Gaming licenses every device and table under SDCL Chapter 42-7B. Minimum age is 21.
Nine federally recognized tribes run eleven casinos under Class III compacts. Properties include Royal River (Flandreau Santee Sioux), Dakota Sioux and Dakota Connection (Sisseton-Wahpeton), Fort Randall and Yankton Sioux Travel Plaza (Yankton Sioux), Lode Star (Crow Creek), Golden Buffalo (Lower Brule), Rosebud and Turtle Creek Crossing (Rosebud Sioux), Prairie Wind (Oglala Sioux), and Grand River (Standing Rock). Minimum age is 21.
Deadwood casinos have taken legal sports bets since September 9, 2021. Tribal sportsbooks followed, starting with Dakota Sioux on April 27, 2022. On-site mobile wagering inside a licensed casino is permitted, but the apps refuse bets the moment a player steps outside the property. Minimum age is 21.
The SD Lottery sells Powerball, Mega Millions, Lucky for Life, Lotto America, Dakota Cash, and scratch tickets through licensed retailers only. State law and the lottery's own rules forbid online or mail-order ticket sales. The lottery mobile app exists, but it only scans tickets and pays prizes from $101 to $5,000, with a minimum player age of 18.
Roughly 9,000 SD Lottery video-lottery terminals run in age-21 licensed establishments, mostly bars and small casinos outside Deadwood. Net machine income is split with the state and remains one of South Dakota's largest gambling revenue lines. The minimum player age is 21.
The Commission on Gaming regulates live and simulcast horse racing under SDCL Chapter 42-7. Wagering happens at licensed racetracks and off-track sites. Sweepstakes and offshore casinos remain unauthorized; the Commission's August 2025 alert reminded residents that those operators sit outside any state consumer-protection framework.
No state bordering South Dakota or sitting on the same plains belt has licensed online casino games. Iowa runs the only statewide mobile sports-betting market in the cluster, live since August 2019. Wyoming followed in September 2021. Everyone else sits on retail, tribal-only, reservation-only, or no sports betting at all.
| State | Commercial | Tribal | Sports betting | iCasino |
|---|---|---|---|---|
| South Dakota | Deadwood only | 11 properties | Retail + on-site mobile | No |
| North Dakota | None | 6 resorts | Reservation-only mobile | No |
| Iowa | Statewide (19 casinos) | 4 properties | Statewide mobile since 2019 | No |
| Minnesota | None | 21 properties | None | No |
| Nebraska | 6 racetrack casinos | 5 properties | Retail only since 2023 | No |
| Wyoming | None | Wind River Class III | Statewide mobile since 2021 | No |
| Montana | None | Class III at multiple sites | Lottery-run, retail only | No |
Iowa is the obvious cross-border outlet. Sioux Falls residents sit about 25 miles from the Iowa line, and Iowa apps geolocate within seconds. Wyoming pulls traffic from the Black Hills counties. North Dakota and Minnesota offer nothing extra to a South Dakota player looking for mobile wagering. None of the seven states allow real-money online slots or table games, which is the gap any future SD iGaming push would have to argue against, not for.
No. SDCL Chapter 22-25A prohibits internet gambling, and the state constitution offers no online-casino exception. The South Dakota Commission on Gaming issued a public alert in August 2025 warning residents that offshore sites and sweepstakes-style casinos advertising to SD players are unauthorized. Any site promoting a 'South Dakota online casino real money' product operates outside state oversight.
Only when you are physically inside a licensed casino. Amendment B in 2020 authorized sports betting only within Deadwood, and tribal casinos opened books under their existing compacts in 2022. Mobile apps from those venues refuse bets the moment you leave the property. Statewide mobile betting failed at the legislature in 2022 (SJR 502) and again in 2026 when the House State Affairs Committee killed SJR 504 by 7-6 after the Senate passed it 23-10.
No. The South Dakota Commission on Gaming's August 2025 public alert treats sweepstakes casinos as unauthorized gambling under SDCL Chapter 22-25A and the SDCL 22-25-1 definition of a wager. The state is not licensing the model, and players have no regulatory recourse if a site stops paying out.
No. The South Dakota Lottery sells Powerball, Mega Millions, Lucky for Life, Lotto America, Dakota Cash, and scratch tickets only at licensed retailers in the state. The lottery's mobile app scans tickets and pays prizes from $101 to $5,000, but it does not sell tickets. Buyers must be at least 18.
21 at Deadwood casinos under SDCL Chapter 42-7B, 21 at tribal casinos under their Class III compacts, 21 for any sports wager, 21 for video lottery in bars and small parlors, and 18 for the SD Lottery's draw and scratch tickets and for parimutuel horse racing.
Not on the current track. No iGaming bill has been introduced in the 2025-26 sessions. Lawmakers cannot even get statewide mobile sports betting past the House State Affairs Committee, which killed SJR 502 in 2022 and SJR 504 in 2026. Authorizing online casinos would require a new constitutional amendment on the statewide ballot, and no sponsor is drafting one as of May 2026.
