One of the biggest draws to playing poker online is that beginners can learn at their own pace. It is often intimidating to sit down at a poker table in a traditional poker room when you're just starting out. In the online world, you can make mistakes without being worried about being embarrassed by more experienced players. Many poker pros got their start playing online and encourage anyone else who wishes to learn the game do so as well.
Online poker is also a top choice for professional and more experienced poker players. The digital dealer deals hands much faster than any land-based dealer could, so players can get in more hands per hour and play Pai Gow Poker. For profitable players, this means making more money in a shorter amount of time.
In the online poker world, you can also find many variations of games that you would rarely find in a land-based poker room. Games like Omaha and Stud poker are commonly found online, but rarely seen in traditional card rooms.
