Gambling is an activity where people risk money or belongings to predict the outcome of a game involving chance, such as on scratchcards and fruit machines or by betting with friends. The purpose of gambling is to win money, but it can also be a way to relieve stress and socialise with friends.

Some people gamble as a form of entertainment, but others become dependent on it and start to spend more than they can afford.
