Some popular mobile online gaming titles in Thailand include Garena RoV, Garena Free Fire, Roblox, and PUBG Mobile. For online games on consoles and PCs, Thais prefer multiplayer online battle arena (MOBA) titles such as Dota 2 and League of Legends.
Please note that even though there is no direct law against online casinos in Thailand, they are still considered to be prohibited by the government officials. So, do not get involved in any kind of gambling activity other than the legal ones to be safe.
