The number of tables jumps into the hundreds until the end of July, with some of the biggest tournaments of the year and all kinds of cash games running. However, at the beginning of every summer, the Rio transforms its poker room into the biggest one in the world to host the World Series of Poker. In fact, for most of the year, the Rio’s poker room is one of the more modest ones in Las Vegas, only offering around 10 cash game tables and small daily tournaments.

The Rio shouldn’t actually be on this list at all since there are plenty of bigger poker rooms around. In fact, only one poker room outside of the US can even compare! With that in mind, let’s take a look at which poker rooms are the biggest in the world. It probably won’t come as a surprise to the majority of poker players that most of the biggest poker rooms are located in the US. If you are a recreational player, you don’t want to wait for ages on waiting lists and if you’re a pro, having a vast selection of tables is always welcome. Players can argue for ages about which poker room is the best and there are good arguments for many of them.
