The legality of online casinos is a tricky subject to address, as laws vary greatly in different jurisdictions. In the United States, for instance, it would certainly be safe to say that operating an online casino is against the law; however, players have never been prosecuted for gambling on websites, and even in cases where the US government has determined that online gambling sites were illegal – such as in the recent case against PokerStars, Full Tilt Poker and Absolute Poker that rocked the online poker world – players were able to get their money returned to them, and no action was taken against those who played on the site.
In most parts of the world, playing on gambling websites, including online casinos, is unambiguously legal. However, there are many nations in which only certain sites are endorsed by local governments; for instance, France and Italy have recently introduced legislation that allows online gambling, but only on sites licensed by their respective governments.
As always, if you’re unsure about the laws in your jurisdiction, check to find out exactly what is permitted and what is not before you begin gambling online. In most cases, you’ll find that there are no prohibitions against online gambling; if there are, it’s likely the case that these laws are targeted at individuals and companies operating online gambling sites, and not players who choose to gamble on existing sites.
