Gambling is an activity in which someone puts something of value at risk on the outcome of a random event. It is common for people to gamble as a way to enjoy entertainment or to win money, but some become addicted to gambling and are unable to control their behavior. There are many factors that contribute to developing a gambling addiction, including mental health problems and social and environmental conditions. Some people are more susceptible to gambling than others, including people who have family history of addiction, depression, impulsivity and boredom susceptibility, poor understanding of probability and use of escape coping, as well as stressful life experiences.

Some forms of gambling are private, such as playing card games with friends in a home setting and betting on events like horse races or football matches within a social circle. Some public gambling takes place in casinos, on cruise ships and in other venues. Gambling can also be done online or over the phone.

The majority of people who gamble responsibly and find it an enjoyable diversion, but 20 percent overindulge and are unable to control their behavior, leading them into debts that impact their ability to support themselves and their families. It is important for individuals to strengthen their support network and seek help if they are concerned about their gambling habits. A good place to start is with a peer support group, such as Gamblers Anonymous, which follows the model of Alcoholics Anonymous, and may be available in a local community.
