Yes, gambling is largely illegal in Thailand. For example, the extent of gambling in Thailand in terms of sports betting and the national lottery is widespread. However, on the other hand, thankfully, when it comes to online gambling in Thailand, it is 100% legal. In one way or another, online gambling is a better form of gambling in Thailand today because it is relatively not only more convenient and easy but also it is much more private and safe than playing at illegal anti establishment casinos.
