No. Gambling is illegal in Thailand apart from narrow exceptions, chiefly the state lottery run by the Government Lottery Office; there are no legal casinos, and a bill to allow them was withdrawn in July 2025 and had not become law by November 2026. Even carrying more than 120 playing cards is an offense, according to the UK Foreign Office.
For a visitor, that means one simple rule: do not gamble in Thailand, whether at a card table in a bar, through a betting app on your phone or with a bookmaker at a boxing match. This page explains what the law covers and where the exceptions lie. It is general information, not legal advice; if you are in trouble, contact a lawyer or your embassy.

The 1935 Gambling Act: a ban with permits
Thailand's gambling law dates from 1935, B.E. 2478 in the Thai Buddhist Era calendar. Its starting point is a prohibition: most forms of gambling are not allowed, and only a few exceptions exist. The UK Foreign Office sums up the result in one sentence, "Thailand has strict laws on gambling", and its travel advice does not describe any form of betting that a tourist may join.
Many websites list horse racing at licensed clubs and certain permitted games as further exceptions. We could not read the Act's text on the government's law database, so we cannot confirm which activities a permit can cover or what penalties apply to players compared with organizers. If your question goes beyond "can I play", ask a Thai lawyer.
The legal exception: the Government Lottery
The state lottery is the form of gambling you will actually see. The Government Lottery Office (GLO) runs it: six-digit lottery tickets, a newer three-digit-number lottery and "digital lottery" sales through an online platform.
The GLO also runs a gambling-harm education project and an online self-assessment for lottery addiction risk on its website. We did not find a GLO statement on whether foreign visitors may buy tickets, so if you are curious, read the GLO's own pages before you buy one; we do not explain how to play or how to claim a prize.
The 120-card rule
This is the rule that surprises travelers most. Under the Playing Cards Act of 1943, B.E. 2486, the FCDO says it is illegal to carry more than 120 playing cards, and that a violation "could lead to prosecution, a fine, or even imprisonment". The FCDO gives no fine amount.
A standard pack has 52 cards, plus jokers, so two packs stay under the limit and three go over it. If you travel with several decks, for a card game on a beach or for magic tricks, leave the extras at home. Our page on Thai customs allowances lists other items worth checking before you pack.
Three packs of cards in your bag is already over the limit. The FCDO's figure is "more than 120 playing cards". That is less than three standard packs, so a card-playing family can reach it without noticing.
Online betting and betting apps
No source we read supports the idea, common on forums, that betting on foreign websites is legal for tourists in Thailand. The 1935 Act prohibits most gambling, and it makes no exception for gambling done on a phone. Be wary of gambling sites in general: several official-looking web addresses we checked for other pages, including an old hotline site and a former museum domain, now redirect to online gambling.
Gambling on election results is also an offense; the Election Commission listed it among the banned activities for the local elections of June 2026. If someone invites you into a private card game, a lottery club or a betting group on LINE, the safe answer is no. Most scams aimed at visitors follow a script that starts with a friendly stranger, as our overview of whether Thailand is safe to visit explains.
Betting at muay thai fights
At Bangkok's traditional boxing nights you will see Thai fans shouting and signaling bets across the stands. Rajadamnern Stadium describes legal public betting among local fans on its traditional nights. That is not an invitation to visitors. Our guide to Bangkok's muay thai stadiums covers tickets, seats and etiquette, and our advice there is to watch the betting, not join it.
Casinos: the Entertainment Complex bill
There are no legal casinos in Thailand. A government bill to allow casinos inside large "entertainment complexes" was withdrawn in July 2025. Reports of a revival have appeared since, but we found no official record that the bill has been passed or published in the Royal Gazette, so treat any claim that casinos are now legal as wrong. As of 9 November 2026, casinos remain illegal.
Casinos do exist just across some of Thailand's borders, which is why tours sometimes offer a crossing. The Golden Triangle is one example; our page on the Golden Triangle and Chiang Saen explains the UK warning about the economic zone on the Lao side and the US sanctions on the criminal network behind its casino.
If you are caught
Breaking the gambling law is a criminal matter, and the FCDO's warning on playing cards mentions prosecution and even prison. Our page on what happens if you are arrested in Thailand covers your rights at the police station, interpreters and how your embassy is told. A conviction can also follow you: our guide to a criminal record and entry to Thailand explains how a prison sentence can affect a later visit.
Gambling is one of several Thai laws that catch visitors out; the most serious are the drug laws. Vapes are banned too, as our page on the vaping ban in Thailand explains, and dropping a cigarette butt in the street can bring a fine, as described in our guide to littering fines and street rules.
Frequently asked questions
Are there casinos in Thailand?
No legal ones. The bill that would have allowed casinos in entertainment complexes was withdrawn in July 2025, and we found no official record that it has been passed since. As of November 2026, running or playing in a casino in Thailand is not legal.
Can tourists buy Thai lottery tickets?
The Government Lottery Office runs the only legal lottery, with paper tickets and digital sales through its platform. We found no GLO statement on whether foreign visitors may buy them or claim prizes, so check the GLO's own information before you buy.
Is it illegal to carry playing cards in Thailand?
Carrying more than 120 playing cards is illegal under the Playing Cards Act of 1943, according to the UK Foreign Office, which warns of prosecution, a fine or imprisonment. One or two ordinary packs stay under that limit.
Is online gambling legal in Thailand?
We found no source that makes online gambling legal, for Thais or for visitors. The 1935 Gambling Act prohibits most forms of gambling, and it has no exception for websites or apps. For your own situation, ask a Thai lawyer rather than relying on forum posts.
