Gambling: broadly illegal, with two legal exceptions — and a casino debate in flux

Facts verified · 2026-07-11

Gambling is illegal in Thailand by default under the Gambling Act B.E. 2478 (1935), which bans most betting, card games for money, and the operation of gambling dens. There are two long-standing legal exceptions: the state-run Government Lottery (the twice-monthly draw) and licensed horse racing. Everything else — casinos, unlicensed lotteries, sports betting, and online gambling in all its forms — is unlawful, and online gambling is actively policed, with sites blocked and account holders investigated. Playing informally for small stakes is technically an offence, though enforcement focuses on operators.

The live question is casinos. An "Entertainment Complex" bill that would license a small number of integrated resorts with casino floors was approved in principle by the cabinet in early 2025, then shelved in mid-2025 after public opposition and political upheaval, and lapsed when parliament was dissolved at the end of 2025. As of mid-2026 it is being revived under a new coalition, with debate possible later in the year — but as things stand today, no casino is legal in Thailand, and you should treat any that appears to operate as illegal.

The Entertainment Complex / casino legislation is genuinely unsettled in 2026 — it has been proposed, shelved and revived repeatedly; nothing has passed, so verify the current legal state before assuming casinos are permitted.
