Online Gambling is when people use the Internet to gamble, either for real money or virtual credits. In order to play, a person needs three things: a computer or mobile phone with an Internet connection, and some money. Some online casinos require that players download software onto their devices before they can access their games, but most offer instant-play options. Those who choose to play for real money can deposit funds into their account and then use the cash to wager on games or sports events. Winnings are typically deposited into the account or paid via a check sent to the player.

Some states have regulated online gambling, but others have banned it altogether. In the United States, the Unlawful Internet Gambling Enforcement Act (UIGEA) prevents financial institutions from processing transactions for online gambling services, and allows the Secretary of the Treasury to prohibit specific payment methods that can be used to finance such activities. In addition, the federal Wire Act makes it a crime to transmit money to an online gambling establishment.

While gambling is fun for many, those who develop a problem are at risk for serious consequences. These include financial strain, emotional stress, disrupted social and work relationships, and feelings of withdrawal when a person attempts to cut back on their gambling. Recognizing a gambling problem is the first step toward change. In addition to counseling and support groups, treatment may include medication to manage underlying mental health conditions.
