The game of poker involves both luck and skill. In the short term, luck can play a significant role in determining the outcome of individual hands or sessions. However, over the long term, skill becomes a more important factor in determining success in poker.

Five-card draw (also known as Cantrell draw) is a poker variant that is considered the simplest variant of poker, and is the basis for video poker. As a result, it is often the first variant learned by new players. It is commonly played in home games but rarely played in casino and tournament play.
