18+ South Dakota Casinos
A $5 bet was the most you could place when Deadwood legalized casino games in 1989. The cap is now $1,000, but you still have to be 21 to place it: poker and table games in Deadwood, and at tribal casinos that serve alcohol, are for players 21 and over.
Some tribal casinos that do not serve alcohol let players in at 18 for bingo and other real-money games, so the list of South Dakota’s 18+ local casinos is worth checking venue by venue. Eighteen is also the age for the lottery, charitable bingo and raffles, and pari-mutuel bets on horse and dog races, at the track or by simulcast.
No South Dakota law prohibits licensed offshore online casinos, and the ones we list accept players from 18 for casino games, poker and sports betting. Anyone planning a trip can compare the other states within the US that allow 18+ casinos.

Is It Legal To Gamble Online In South Dakota?
It is only legal for South Dakota players to gamble at offshore online casinos. While online casinos require different minimum gambling ages from 18, 19, to 21, not every online gaming site will accept players from SD or the US. This is due to conflicts in regulations and requirements between the US and online brands.
US federal law does not prohibit US citizens from participating in legal online casino gambling while also allowing states to regulate their own state-based gaming sites or completely ban access to offshore online sites. Thankfully, most states do not specify any prohibitions against foreign online gambling; thus, federal law takes precedence.

Brief History Of South Dakota’s Gambling Laws
South Dakota’s gambling roots come from its gold rush period. Once gold was discovered in the Black Hills of South Dakota in 1874, gold-miners rushed to this prosperous state. In 1876, Deadwood turned from a gold camp into a gold-fueled town as gamblers, outlaws, gold prospectors, and gunslingers fed into the growth of this town.
Home to famous figures like Wild Bill, this town underwent several fires and hardships that led to the abandonment of Deadwood and was long forgotten until 1989.
During the late 1800’s and early 1900s SD experienced the same blanket ban on gambling as other states within the US did.
In 1933, pari-mutuel wagering was legalized as a way to bring economic development and revenue to the state to combat the Great Depression.
In 1987, charitable gambling was allowed in SD.
By 1988, the first scratch-offs were sold.
In 1989, casino games were allowed within Deadwood city limits with a $5 maximum bet. Video lottery terminals were also legalized.
In 1990, off-track wagering on horse and dog races was permitted.
In 1992, the first lotteries were sold and drawn.
In 1993, tribal gaming compacts were signed with SD.
By 2000, bet limits were raised to $100.
In 2012, maximum bet limits were increased once again and set at $1,000.

FAQs
South Dakota’s minimum gambling age varies across gambling venues. At 18, residents and state visitors can play the lottery, bingo, and participate in parimutuel gambling on horse and dog races, charitable gambling, and gamble at some tribal casinos in the state that do not serve alcohol. However, those players at least 21 and older can gamble on poker and casino games in Deadwood and other tribal casinos that serve alcohol.
SD players that gamble on legally sanctioned and licensed online casinos are safe and protected under federal law. Our list only features safe and legal gaming destinations, however, not all casinos found online are legal or safe, this is because most illegal sites disguise themselves to seem legitimate.
This is why we personally review each brand for legality, security, and even quality before we include them in our guides. Illegal online casinos have a habit of excluding their licensing, credentials, certificates, audits, and fair gaming compliance from their websites which should be a huge red-flag to players even thinking about putting their money and information on these sites. Be safe and stick with verified and recommended gaming sources.
This answer depends on whether the online casino provider is using random number generators in their games. If an online gaming site states that they are utilizing RNGs and show their audits from third-party testing agencies, then you can rest assured that their games are fair and provide honest results.
However, if the gaming destination does not state its usage of RNGs and does not present its audits or fair gaming practice compliance then you can assume that their games are rigged and not fair to players.
Not every legal online casino will accept SD players. This is due to conflicts between the US and certain international brands. For this reason, there are many online casinos that do not serve American players at all, and for the few that do, they require players to be 21, not 18. This is why we did all of the legwork and provided a list in our guide of verified legal brands that accept 18+ players from SD.
Absolutely. Mount Rushmore State players can enjoy full access to games on their preferred device, whether a cell or tablet. This is because online casinos have become forward-thinking and created web-based applications for their desktop casinos.
