Gambling Laws in South Korea

South Korea takes a split approach to gambling. The state runs a set of authorized games that Korean citizens can play, from horse racing to the lottery, and it licenses casinos that only foreign visitors may enter. Everything outside those categories is prohibited under criminal law, and the law reaches further than most: it applies to Korean citizens even when they gamble in countries where it is perfectly legal. This page explains what is allowed, who may play what, and what the rules mean in practice.

What gambling is allowed

The National Gambling Control Commission recognizes seven authorized gambling industries: casinos, horse racing, cycle racing, motorboat racing, lotteries, sports promotion voting tickets, and bullfighting¹. The official support pages of the racing bodies list the same set: casino, horse racing, cycle racing, motorboat racing, lottery, sports promotion voting ticket, and bullfighting⁵.

For Korean citizens, most of these are genuinely accessible:

• Horse racing at tracks run by the Korea Racing Authority, including LetsRun Park in Seoul and Busan-Gyeongnam¹
• Cycle racing and motorboat racing at venues such as Gwangmyeong Speedom and the Misari motorboat park¹
• Lotteries, including Lotto 6/45 and instant games, sold at outlets nationwide¹
• Sports Toto, the sports promotion voting ticket, covering soccer, basketball, and baseball pools plus fixed-odds Proto betting¹
• Bullfighting events, a small traditional category¹

The one big exception is the casino. Korean nationals are permitted to gamble only in limited circumstances, typically small wagers for entertainment, at a handful of government-approved venues such as the horse racing track in Seoul and Kangwon Land⁶. Outside the authorized categories, gambling is prohibited under Korean criminal law⁷.

So the practical picture for a Korean citizen is: buy lottery tickets, bet on the state's racing and sports pools, or make the trip to Kangwon Land. Anything else, from a private poker game for money to an offshore betting site, falls under the criminal law.

Casinos open only to foreign visitors

Korea's casino industry is open only to foreign visitors, as domestic gambling is tightly controlled under the law⁸. There are 17 land-based casinos in the country, and 16 of them are legally reserved exclusively for foreign passport holders and expatriates². Only foreign passport holders may enter 16 of the 17 casinos⁹.

The rules at the door are simple and strictly checked:

• Bring a valid foreign passport or identity document; entry requires a nationality check¹⁰
• The minimum age at foreigner-only casinos is 19²
• Korean citizens are absolutely barred from entry¹¹

The one exception is Kangwon Land, the casino at High1 Resort in Gangwon Province, which is the only casino in Korea where both Koreans and foreigners are allowed to gamble¹². It exists under a special provision of the Tourism Promotion Act, which otherwise keeps residents out of licensed casinos³.

The foreigner-only list includes well-known venues such as Paradise Casino Walkerhill in Seoul, Seven Luck Casino in Seoul and Busan, Inspire Casino and Resort in Incheon, and the cluster of casinos in Jeju¹³. Paradise City, near Incheon airport, is the largest-scale foreigner-only casino in the country⁸. Poker rooms such as Paradise Grand Casino Jeju are likewise open to foreign passport holders only¹⁴.

This arrangement is unusual. Korea and Vietnam are the only countries that operate foreigner-exclusive casino operations¹⁵. The policy has a long history: the government has said new casino licenses would only be approved for foreigner-only operations¹⁶, and plans for casino resorts in places such as Saemangeum were drawn up around casinos catering to non-Koreans only¹⁷.

For a visitor, the system works smoothly. Tourists can gamble in casinos scattered throughout the country¹⁸, and the industry has been regaining momentum as Chinese group tourists return¹⁰. If you are planning a trip, our casinos in South Korea page lists the venues by city, and our guide to gambling in South Korea as a visitor covers the practical details.

Online gambling

Online gambling in South Korea is prohibited, even though some forms of land-based gambling are legal³. The ban covers online casino games and online poker, both listed as prohibited, and it applies to residents regardless of where a site is based¹⁹. Online sports betting exists only as a state monopoly through the authorized pools¹⁹.

The authorities have made it clear that those caught gambling online face penalties and charges³. Korean citizens are advised not to join international online casinos, or they will face prosecution and punishment³.

The definition is broad. Under Korean law, wagering money online on the outcome of an event is considered illegal gambling, which is why the recent boom in cryptocurrency prediction markets sits in a legal gray zone rather than an accepted market¹³. Even if the site is based overseas, winnings from gambling are considered illegal earnings under Korean law²⁰.

Enforcement is real, and the penalties are spelled out in the law. Article 246 of the Criminal Act punishes anyone who gambles or bets for the purpose of gaining property with a fine of up to KRW 10 million²¹. Habitual gamblers face stiffer treatment, with imprisonment for not more than three years²². Our page on online gambling in South Korea goes into more detail on how the ban works and what sites are blocked²⁰.

Social casinos

Social casino games, the app-based games played with virtual money rather than real cash, sit in a different category. They are not prohibited in Korea, and services are allowed as long as spending regulations are kept²³. In regulatory terms, social casino play is treated as regulated rather than banned¹⁹.

The rules that keep them on the right side of the line are specific:

• Spending is capped at $500 per month per person²³
• Auto-betting is not allowed²³
• Games must include a self-control system that blocks a player from other gambling games from the same company if spending exceeds one-tenth of the monthly purchase limit within 24 hours²³

So a Korean player can legally enjoy slot-style or poker-style app games with virtual chips, but the games cannot be designed to feel like automated real-money betting, and heavy spenders get locked out automatically.

Gambling by Korean nationals abroad remains punishable

This is the part of Korean gambling law that surprises most people. Korea prohibits gambling by its nationals under the Criminal Act and related laws, and a national who participates in gambling in a country where gambling is legal, online or offline, can still be punished under domestic law⁴. The prohibition applies to Koreans abroad²⁴.

The legal basis is the personality principle: the Penal Code applies to crimes committed by South Korean citizens even abroad, alongside the territorial principle for crimes committed inside Korea¹¹. A Supreme Court ruling put it plainly: gambling at a foreign casino that does not punish gambling is not thereby stripped of illegality; it remains punishable for Korean nationals²⁵. The same logic extends to sports betting: liability is the same even where the sports gambling site is operated outside South Korea by foreigners²⁶.

There is an important soft edge, though. The courts distinguish casual play from gambling trips:

• A one-off visit during travel, or gambling once with family or friends for a not-very-large amount, is treated as temporary amusement and is not punished¹¹
• Leaving the country in order to gamble, or gambling repeatedly with large amounts, is treated as an overseas gambling trip and is clearly punishable¹¹

In other words, a Korean who drops a small sum at a Macau or Las Vegas table during a family holiday is in a different position from one who flies out specifically to play. Our page on gambling trips abroad from South Korea covers where Koreans actually go and how the rules apply.

Penalties for players: fines and imprisonment

The penalties sit in the Criminal Act. Article 246 stipulates that a person gambling for the purpose of gaining property is liable to a fine of up to KRW 10 million². Unlawful gambling may be punished by a fine not exceeding KRW 10 million, except gambling for a mere pastime²⁷.

The heavier tier applies to repeat behavior. Habitual gamblers can be punished by a prison sentence of up to 3 years or a fine of up to KRW 20 million². Habitual unlawful gambling is subject to imprisonment for not more than three years or a fine not exceeding KRW 20 million²⁸.

In summary:

Two related points are worth knowing. First, a Korean national who enters a foreigner-only casino using a forged passport faces severe punishment if caught¹¹. Second, overseas gambling often brings a companion charge under the Foreign Exchange Transactions Act, the offense known as hwichigi (currency smuggling), which can make the final punishment heavier¹¹.

Enforcement in practice: when citizens are prosecuted

Enforcement against Korean players using offshore gambling sites is ongoing⁶. Gambling is illegal for Korean citizens under the Criminal Act, and every casino other than Kangwon Land is restricted to foreign passport holders²¹. Illegal gambling, in the official definition, includes internet gambling, hwatu (Korean playing cards), poker, and adult arcades⁵.

In practice, prosecutors focus on the patterns described above: people who travel abroad specifically to gamble, people who gamble repeatedly with large amounts, and people who move money through unofficial channels to fund it¹¹. A single casual flutter on a trip is rarely pursued; organized overseas gambling trips and offshore site activity are¹¹.

The scale of the underground market is large enough that there have been calls to establish a unified task force to combat illegal overseas gambling⁶. Illegal gambling also carries a high risk of gambling addiction, and the official guidance is to be careful, since those caught are punished under the relevant laws²⁹. If you or someone you know is struggling, the racing bodies' clinics and our gambling help in South Korea page list the support services available, including self-exclusion and entry limits.

For foreign visitors, none of this is a concern: the casinos, the racing tracks, and the lottery are all open to you with a passport, and the foreigner-only casinos are set up entirely around your business.
