Gambling games are games where players place bets in hopes of winning prizes. This is an activity that is incredibly popular around the world, generating $335 billion in legal revenue in 2009 alone. These games have many variations and can involve nonmonetary objects, such as cards or marbles. In games like Magic: The Gathering, players may stake their collectible game pieces.

Poker, for example, has become incredibly popular in recent years. Poker tournaments are broadcast on television and are also available online. Another type of internet gambling is betting exchanges, which allow players to make wagers with other players for a small fee. This is a new and rapidly growing area of online gambling.

The use of social media has changed the landscape of gambling. While formerly limited to racetracks and brick-and-mortar venues, gambling has now become a global industry, and social media sites have received more attention from gambling researchers than ever before. People can access online gambling venues through hyperlinks in advertisements on social media sites, and they can also access free-to-play simulated gambling games via applications.

Increasing access to online gambling has influenced young adults’ behavior. Social casino games have been an increasingly popular option for social networking users, and online gambling is a big part of this. However, there is a risk of addiction to online gambling.
