Gambling is risking something of value on an event that relies largely on chance, for example, betting on sports events, casino games or scratchcards. The chances of winning are calculated and presented as ‘odds’, which are generally higher for events with greater uncertainty, such as football matches or buying scratchcards.

Gamblers can also play casino-style games on computers or mobile devices, which are accessible 24 hours a day. These online games require a high degree of concentration and may also increase the risk of gambling problems.

Some people can become addicted to the thrill of gambling and despite it being a recreational activity, it can lead to serious problems. Problematic gambling can affect a person’s life in many ways and is often associated with depression, anxiety or other mental health issues. It can cause relationships to break down, result in work difficulties and even lead to unemployment. It can also be very difficult to get out of debt if someone becomes a gambler, especially if they continue to win or lose money over time.

Those who are not affected by a gambling disorder can learn how to control their urges through various methods, including peer support groups, such as Gamblers Anonymous. Counselling is also available, which can help people understand their relationship with gambling and think about how it affects them and their family. It can also provide information about available treatment options. Research has found that gambling can change parts of the brain involved in feeling reward or excitement, and that treatment can slowly reverse these changes.
