No, online gambling and online casinos are not legal in Singapore. Almost all forms of gambling are prohibited in Singapore. Thus, all casino games are outright ban in the country. Moreover, overseas gambling sites are ban as well. However, very few land-based gambling establishments are an exception to the rule. Furthermore, there is no proper license-issuing body in place. Therefore, there are no existing legal online casinos in Singapore.
However, according to all legal experts, it is not illegal to gamble from foreign sites in one's own home. Therefore, it means that Singaporean residents can take advantage of this. And, in turn, many foreign online casinos accept Singaporean players. Notably, these offshore online gambling sites are licensed and regulated in their jurisdiction.
