Gambling is a risky activity in which someone stakes or risks something of value on an event with uncertain outcome (e.g., a football match or a scratchcard). It includes any game of chance that involves an agreement between two parties in which each will receive something of value contingent upon the outcome of an event not under their control or influence. It does not include bona fide business transactions, such as buying securities or commodities at a future date, contracts of indemnity or guaranty, and life, health, or accidental insurance.

The act of gambling can be a harmful behaviour and can lead to serious problems like debt, bankruptcy and loss of relationships. In some cases, the problem can escalate to involve illegal activities like stealing, fraud and money laundering. The first step in overcoming a gambling addiction is to recognise that there is a problem and get help.

It is important to only gamble with money you can afford to lose, and to set limits for yourself on how much time and how much you will spend gambling each week. It is also a good idea to avoid online betting sites and to keep your bank accounts closed and limit the amount of cash you carry with you.

It is also a good idea to learn how to manage negative emotions in healthier ways, and find other sources of enjoyment and socialization. Many people turn to gambling as a way of self-soothing unpleasant feelings, such as loneliness, boredom or anxiety, but this can be an expensive and harmful habit.
