Yes, it is. Most card games that include betting are legal in the US, except in states where gambling, in general, is illegal. However, it’s tough to find Andar Bahar in land-based casinos in America. That’s a bit different when it comes to online Andar Bahar, as the status of online casinos depends on the state you’re in. In most states, online gambling is prohibited, but that only applies to casinos operating within state borders. Still, as a player, you’re free to visit offshore casinos and play the game without fear of prosecution.
