Gambling is an activity in which you bet money on an uncertain event. In many cases, the bet is against your own interests. If you win, you make money; if you lose, you lose the money you bet. Most often, people gamble because they are trying to win something of value. However, some people gamble for purely intellectual purposes.

Gambling has a negative impact on families and individuals. Often, people who start gambling become addicted to it. This behavior is called pathological gambling.
