Thailand Gambling Laws

Thailand is one of the strictest gambling countries in Asia, and also one of the most enthusiastic. The government lottery draws twice a month to long queues, horse racing runs at state tracks, and an enormous illegal market, from underground lottery numbers to online casinos, fills the gap the law leaves open. This page explains what the law actually says, what happens if you break it, and what is changing.

What is legal in Thailand: the two exceptions

Only two forms of gambling are legal in the country: the government lottery and horse racing operated by the state¹. Every press account of Thai gambling policy repeats the same fact: the only legal forms of gambling are an official lottery and state-run horse racing⁶.

That is the whole list. There are no legal casinos, no legal sportsbooks, no legal poker rooms, no legal bingo halls. The government lottery is so embedded in Thai life that researchers have called it the only legal form of gambling in Thai society⁹, and it is enormously popular, with draws on the 1st and 16th of each month. You can read more about it, including ticket prices and prize tiers, on our Thailand Lottery page, and about the newer digital lottery and N3 lottery.

Horse racing is the other exception. Betting is legal only at the state-controlled racecourses, not on any online platform. Our Horse Racing in Thailand page covers the tracks, race days and how to place a bet.

Everything else, from a card game with money on the table to a bet on a football match, falls outside the two exceptions. Even traditional Thai games like Pok Deng, which nearly everyone knows how to play, are illegal the moment money or anything of value rides on the outcome.

The Gambling Act of 1935 (B.E. 2478): the legal basis

The foundation of it all is the Gambling Act B.E. 2478, passed in 1935. Most forms of gambling in Thailand are prohibited under it unless explicitly licensed¹⁰, and it bans nearly every form of gambling outright, carving out only the narrow exceptions described above¹¹. The Act prohibits all forms of betting and games of skill or chance where a wager, in money or goods, is placed on the outcome¹².

A few things worth knowing about how the Act works in practice:

• It is old. Written in the 1930s, it does not directly mention the internet, which is why online gambling sits in a gray zone rather than being named and banned the way casinos are¹³.
• It distinguishes types of gambling. Some activities are banned outright, while others fall into categories that require special permission, which is how poker was eventually able to be reclassified¹⁴.
• It applies to everyone in the country. There is no carve-out for tourists, expats or diplomats².

The Act also contains provisions for taxing certain types of gambling, which is where the stamp duty on lottery prizes comes from¹⁵. Gambling has been officially banned since 1935, and the ban has been strictly enforced for most of the decades since¹⁶.

Penalties for players: fines and imprisonment

What actually happens if you are caught? For ordinary players, the penalties range from 500 to 5,000 baht, roughly $15 to $150, and people found gambling are usually just fined, though imprisonment of up to three years is possible depending on the severity of the offense². Being found in an underground poker room can mean a fine or even one year in jail¹⁷.

Specific offenses carry specific maximums. Football gambling, for example, is punishable by imprisonment of up to 2 years or a fine of up to THB 2,000, or both¹⁸. The police do raid illegal venues, and they also raid private homes: in one widely reported 2025 case, police raided friends playing a board game at home because betting was suspected, and violators may face fines or imprisonment¹⁹.

A few practical points:

• Small-stakes home games are not safe. The board game raid shows that even a private gathering can attract police attention if money is involved¹⁹.
• The severity usually depends on your role. A player in a raided venue typically faces the lower end of the fine range; organizers and venue owners face far more serious charges².
• Paying a fine does not necessarily end the matter for foreigners, who also face immigration consequences (see below).

Online gambling: a gray zone the law does not directly cover

Online gambling is where the 1935 Act shows its age. The Act does not cover online gambling directly, but it bans nearly all wagering activities, so the country's gaming landscape remains in a gray zone¹³. There is no legal sportsbook, no legal online casino, and no legal bookmaker of any kind in Thailand¹¹, and no online casino has ever been approved or regulated by the Thai government²⁰.

In practice, many residents gamble online anyway, using offshore operators licensed in other jurisdictions, led by Curacao²⁰. One directory counts 867 casinos accepting players from Thailand²⁰. But the practical reality and the legal reality are different things: using offshore betting sites is illegal for Thai residents regardless of where the operator itself is based¹¹. A license in Curacao or Malta protects the operator, not the player sitting in Bangkok.

The pending entertainment complex bill did not address online gambling at all; it is land-based only¹¹. So there is no sign of licensed online gambling arriving in Thailand soon. Our Online Gambling in Thailand page goes deeper into how people actually play, and Gambling Payments in Thailand covers the money side.

Foreigners and expats: same penalties, plus deportation

The Gambling Act applies to foreigners exactly as it does to Thai citizens. The penalties are the same, and the authorities have been known to hold foreigners in jail to await deportation, with fines and deportation often the combined response². For an expat, that can mean the end of a visa and residence, not just a fine.

When licensed casino resorts eventually open, the plan is the opposite: the complexes will be open to all foreigners²¹, and the bill will allow foreigners as well as Thai citizens to play in the casinos²². Under the draft rules, foreigners entering a casino will need to present a passport or an equivalent document, and an entry levy will be charged to foreigners¹⁵, similar to the system in Singapore. Our Gambling in Thailand as a Visitor page has more for tourists.

Tournament poker: officially legal, framework pending

The biggest recent change is poker. Tournament poker became officially legal in Thailand in August 2025, when the acting prime minister overturned a long-standing ban³. The first tournament under the new rules ran on July 31, 2025, delayed by one day from its planned July 30 start¹⁴.

But the details are still being worked out. The ban was lifted by ministerial order, while the legislative framework is still being studied, and competitions may initially be allowed only on a case-by-case basis while a committee works through the rules⁶. Poker remains under Category B of the Gambling Act, activities that require special permission¹⁴, and it can only be played during specific events, and only after a formal Poker Sports Association is established¹⁴. A full legal framework governing the new law has yet to be implemented³.

Cash games and online poker are a different matter. Any poker game is still viewed as gambling in Thailand rather than a mind sport¹⁷, and online poker should be treated as a legally high-risk activity, with no platform formally licensed by Thai authorities¹⁰. That said, there has not yet been a reported case of a poker player getting into legal trouble simply for playing online². Our Poker in Thailand and Poker Tournaments for Thai Players pages cover the practical side.

Casino plans: Bangkok, Phuket and Pattaya

Thailand is moving toward legal casinos for the first time since 1935. The cabinet approved a draft law to legalize casinos and entertainment complexes in January 2025⁷, and the government had already forged ahead with the plan after public consultation in 2024⁸.

The shape of the plan:

Five potential sites have been identified: two in Bangkok, and one each in the Eastern Economic Corridor, Chiang Mai and Phuket⁴. Both tourists and Thai residents will be permitted to enter and gamble¹⁶. The bill sets the minimum gambling age at 20⁵, and individuals under 20 will be prohibited from entering the venues⁴. For Thai citizens, an earlier version of the plan proposed that only Thais who are at least 20 and have a minimum 500,000 baht in bank accounts would be allowed to gamble²³. The government will have the final say on casino locations²¹.

If it all happens, analysts think the casino plan could put Thailand behind only Las Vegas and Macau in gaming revenue⁵, and could make the country the main gambling hub in Southeast Asia¹⁶. Neighboring countries are watching closely, with Cambodian casinos on notice as Thailand finalizes the new law²². We cover the whole project on our Thailand's Entertainment Complex Casino Plan page.

Taxes on winnings: 15% withholding above THB 1,000

If you do win, tax comes into play. As of 2022, Thailand imposes a 15% withholding tax on gambling winnings exceeding 1,000 baht²⁴.

For the legal lottery, the deductions are different and happen at the counter when you claim. Government lottery prize claimants must pay stamp duty at the rate of THB 1 per THB 200 of prize money, or part thereof²⁵. Charity lottery prizes have income tax withheld at source at 1 percent of the prize money²⁵. Some sources describe the lottery stamp duty as 0.5 percent, which matches the 1 baht per 200 baht rate²⁷.

Online casino winnings, including from foreign online casinos, are taxable as assessable income under Section 40 (8) of the Revenue Code for Thai players²⁷. Our Tax on Gambling Winnings in Thailand page has the details and worked examples.

Where to get help with gambling

Thailand has no legal self-exclusion register and no national responsible gambling system, but there are real places to turn. The Department of Mental Health under the Ministry of Public Health runs a gambling quitline on 1323, a call center available 24 hours a day, with free calls and web chat²⁸. The Social Help Center hotline 1300 offers 24/7, free and confidential support and information²⁹, and you can contact a gambling hotline in Thailand for free and confidential support³⁰. The Government Lottery Office also lists a gambling consultation helpline on 0-2528-9999, press 9, for people who feel anxiety from gambling and their family members³¹. Our Gambling Help in Thailand page collects all of these in one place.
