What exactly is "underground" poker depends on the local laws. In many (but not all) jurisdictions, an unlicensed poker game may still be legal if the game is played in a residential building, the host does not profit from hosting the game, and/or the buy-in fees do not exceed a certain threshold ... Even if the game itself is illegal, in some jurisdictions it is not illegal to just play such a game - in such cases, only the organizers and/or organizers of such games are civilly and/or criminally responsible. The intensity of the harassment of clandestine poker by law enforcement agencies also varies by location. Often, players and hosts of underground poker games are far more concerned with being targeted for armed robbery and other violent criminal acts as opposed to being targeted with legal action.
