Gambling involves risking something of value (money or anything else) on an event that is unpredictable. The event could be a football match, a scratchcard or a game of poker. The player decides what to bet on and then matches that choice to a set of odds, which are the chances of winning. These odds are calculated by the betting company, and can be found on the back of the ticket or in the game rules. The gambler also places a stake, which is the amount of money they are willing to lose if they do not win.

People with mental health problems are also more likely to develop a gambling problem. People who play video games, especially those that require micro-transactions and payments, are also at risk of developing a gambling problem.

People who have trouble controlling their spending, lying about how much they spend and chasing their losses should seek help.

This can impact their physical and emotional health, their relationships and work performance, and they may even face legal problems. It can be hard to recognize gambling addiction, but there are some signs to look out for:
