Gambling is when you risk something of value (like money) based on an outcome that is at least partly determined by chance. It includes activities like betting on sports games or buying scratch cards. Defining gambling helps governments set laws and regulations that protect consumers, maintain fairness, and prevent exploitation.

People may be tempted to gamble for entertainment, but it can turn into a serious addiction if you lose control. Problem gambling is more common among certain groups, such as young people and men. It also tends to affect people with low incomes, who may have more to gain with a big win, and those with depression or anxiety disorders.

You may have a gambling addiction if you are spending more than you can afford, lying to friends and family about your gambling habits, or becoming secretive about your spending. You may also have trouble controlling your emotions and feel compelled to keep gambling in the hope that you will win back what you’ve lost.

It’s important to recognize when you or a loved one has a gambling addiction so that you can seek help and support. You can find help by strengthening your support network, taking up a hobby that does not involve gambling, or joining a peer-support group, such as Gamblers Anonymous, which follows a program based on Alcoholics Anonymous. You can also try hypnotherapy, which has been shown to be effective for many people with gambling problems.
