Legal since 1989, making Deadwood the third legal casino town in America after Nevada and Atlantic City. Around 21 casinos operate inside the city limits, with slots, blackjack, craps, roulette and poker. The maximum bet is 1,000 dollars — raised from five dollars in 1989, then 100 dollars, by a 2012 law.
Legal, and genuinely good for a state this size — though smaller than listings suggest. State figures show exactly 12 player-banked poker tables in all of Deadwood. Three rooms are confirmed running: Silverado Franklin (cash games daily from 10am), Cadillac Jack’s and the historic Saloon No. 10. Several tribal casinos also spread poker on set nights.
Legal statewide, and bigger than the casinos. About 11,120 video lottery terminals sit in roughly 1,400 bars, taverns and stores across South Dakota, capped at two dollars a game. They returned more to the state last year than the entire Deadwood casino industry earned. You must be 21.
Legal but strictly on site. Voters approved sports betting for Deadwood in 2020 and it launched in September 2021; tribal casinos offer it too. There is no mobile app of any kind — not even inside the casinos. You bet at a window or kiosk, at 21 and over, taxed at 9%.
Legal. Roughly a dozen tribal casinos operate across the state’s Sioux tribes under Class III compacts, from Dakota Sioux at Watertown to Rosebud on the Nebraska line. Several have sportsbooks, and a few run real poker — Dakota Sioux has a dedicated poker room on Friday and Saturday nights.
Legal since 1987, run as a division of the Department of Revenue — Powerball, Mega Millions, Lotto America, Dakota Cash and scratch tickets, at 18 and over. There are no online ticket sales and no courier apps; the state’s app only lets you cash a winning ticket.
Legal — and the only real-money gambling you can legally do online in South Dakota. A 2026 law confirmed that licensed totalizator hubs may run online pari-mutuel platforms. Live racing is almost gone, down to a short meet at Fort Pierre, with one simulcast site in the state.
Legal for qualifying groups — veterans’ and religious organisations, charities, fire departments, civic and booster clubs — running bingo and raffles. There’s no state licence; you register locally with the county or city at least 30 days ahead. No bingo prize may exceed 2,000 dollars in a single play.
Available, but never regulated. South Dakota has no fantasy-sports law at all — the state’s posture still rests on a 2015 Attorney General statement declining to prosecute without direction from the legislature. DraftKings, FanDuel, PrizePicks and Underdog accept players here, with no state oversight behind them.
A gray area. South Dakota has passed no sweepstakes ban and no bill has even been introduced, so these sites operate here — unaddressed by state law rather than approved by it.
Not legal. The state constitution bans games of chance unless voters carve out an exception — which is how Deadwood, then craps and roulette, then sports betting each became legal. No online casino or poker bill has been introduced at all in recent sessions, so there’s nothing on the horizon.
A resolution to let voters approve statewide mobile sports betting passed the Senate 23-10, then died in a House committee. Separately, Amendment L on the November 2026 ballot would require 60% approval for future constitutional amendments — sports betting itself passed with only 58.47% in 2020.
The first legal wager was placed on September 9 by Deadwood’s mayor, and the ticket now sits in a museum. Betting stayed inside the casinos — there is still no app.
Amendment B passed with 58.47% of the vote, allowing wagering on sporting events within the city limits of Deadwood — and nowhere else.
Amendment Q added the three games to Deadwood’s legal list, and they went live in July 2015. Keno has been legal ever since — and nobody spreads it; the state’s own figures show zero keno tables.
The legislature raised Deadwood’s maximum bet from 100 dollars to 1,000, twelve years after voters had lifted it from the original five-dollar cap.
After a volunteer campaign to save a decaying historic town, voters approved casino gambling for Deadwood by 65%, and gaming began on November 1, 1989 — the third legal casino jurisdiction in the country. By law, the town’s share of the money must go to historic preservation.
South Dakota is a real gambling state that has almost entirely refused to go online. Deadwood has been a licensed casino town since 1989 — the third in America after Nevada and Atlantic City — and there are around 11,120 video lottery machines in bars across the state, which last year sent more money to the treasury than the whole Deadwood casino industry earned. And yet you cannot legally play a casino game or a hand of poker online here.
The reason is structural. South Dakota’s constitution bans games of chance unless voters specifically carve out an exception — which is exactly how Deadwood got casinos in 1988, how craps and roulette arrived in 2014, and how sports betting passed in 2020. Online casino and poker would need the same statewide vote, and no bill to start that process has even been introduced in recent sessions. Full-iGaming states like Pennsylvania, Michigan and New Jersey license real online casinos; South Dakota isn’t in that conversation.
Even sports betting stops at the county line. Betting is legal only inside Deadwood casinos and tribal casinos, at a window or a kiosk — there is no mobile app at all, not even on the casino floor. Lawmakers have tried three times to put statewide mobile betting to voters and failed each time, most recently in 2026 when a resolution cleared the Senate and then died in a House committee. That matters most in Sioux Falls, home to about a quarter of the state’s population, which sits 385 miles from Deadwood and twelve miles from Iowa, where betting on your phone is perfectly legal.
The one genuine exception is horses: licensed online pari-mutuel wagering is legal, and a 2026 law spelled out who may offer it. Everything else online means unregulated offshore sites with no South Dakota protection. Neighbouring North Dakota runs its bar gambling through charities instead, and Montana through video machines — but all three Northern Plains states share the same answer on online casino and poker: no.
The practical reality: South Dakota’s legal gambling is Deadwood’s casinos and poker rooms, tribal casinos, video lottery in bars, the state lottery, and licensed online horse betting. Sports betting is in-person only — there’s no app anywhere in the state. Online casino and poker aren’t legal and would need a statewide vote to change.
Deadwood is the destination, the bars have the video lottery, and the tribal casinos fill in the rest of the map.

South Dakota’s casino story starts in a town that gambled to save itself. By the 1980s Deadwood was a decaying gold-rush relic; a volunteer campaign put casino gambling on the 1988 ballot, it passed with 65%, and gaming began on November 1, 1989 — making Deadwood the third legal casino jurisdiction in the United States after Nevada and Atlantic City. The deal written into the constitution still holds: the town’s share of the money must be spent on historic preservation. Bet limits started at five dollars, went to 100 in 2000, and reached 1,000 dollars in 2012.
For poker players, Deadwood punches above its weight but is smaller than the internet suggests. State figures put the whole town at 12 player-banked poker tables — the rest of what casinos call ‘poker’ is house-banked carnival games like Three Card and Ultimate Texas Hold’em. Three rooms are confirmed running: Silverado Franklin, with daily cash games from 10am and the state championship series; Cadillac Jack’s, with a poker room and daily tournaments; and Saloon No. 10 — the bar where Wild Bill Hickok was shot holding aces and eights in 1876, and which still deals hold’em, Omaha and stud today. Deadwood marks its 150th anniversary in 2026. Tin Lizzie, The Lodge, Deadwood Mountain Grand, Mineral Palace and Gold Dust have table pits but no live poker room.
Away from Deadwood, roughly a dozen tribal casinos run under Class III compacts across the state’s Sioux tribes. A few genuinely spread poker: Dakota Sioux near Watertown has a dedicated poker room on Friday and Saturday nights with a running bad-beat jackpot, Lode Star at Fort Thompson deals cards Thursday through Sunday, and Grand River at Mobridge runs a weekly game. Others — including Royal River, the state’s largest tribal casino — offer only house-banked card games, whatever some listings claim. One measure of how far Deadwood’s pull reaches: the Wyoming State Poker Championship isn’t played in Wyoming at all — it’s a flight of a tournament series at the Silverado Franklin, because Wyoming has no poker room of its own.
The South Dakota Commission on Gaming, part of the Department of Revenue, licenses Deadwood's casinos, poker rooms and sportsbooks, publishes monthly figures, and runs a self-exclusion request process.
The state Lottery regulates video lottery terminals with statutory bet and payback limits, and tribal casinos operate under federal compacts with tribal gaming commissions. Lottery money also funds problem-gambling treatment.
No South Dakota protection. Online casinos, poker rooms and sweepstakes sites are unlicensed here — no fund segregation, no dispute process, and no recourse if a site refuses to pay.
Our guidance: South Dakota’s regulated options are genuinely good in person — Deadwood’s casinos and poker rooms, tribal casinos, video lottery, the state lottery, and licensed online horse betting. What it lacks is any legal online casino or poker, so playing those means unregulated offshore sites with no state recourse. If gambling stops being fun, South Dakota funds its own helpline, below.
With video lottery in bars statewide and casinos in Deadwood, help is close at hand. If gambling stops being fun — or you're chasing losses — free, confidential support is available 24/7.
