Gambling involves the risking of money or something of value, with an element of chance and the aim of winning. It can include playing card games like poker and blackjack, fruit machines, video-draw poker, slots and two-up; betting on events such as horse races or football accumulators; and speculating on business, insurance or stock market investments. While some skills can improve the odds of winning, it is important to remember that gambling is a game of chance.

Problematic gamblers can experience significant social, family and financial harm. These people often hide their gambling activity, lie about it and attempt to convince others that they can manage their problem. They can also become reliant on medication, alcohol or other substances to help them deal with their addiction.

The human brain is wired to feel excited when we win. But even when we lose, our body still produces a surge of dopamine. This neurological response explains why some people keep gambling, even when it’s no longer fun.

Gambling is a big business. From dealers and odds compilers to marketers and PR staff, all gambling companies need to turn a profit. To do this they need to attract large numbers of customers and keep them coming back.

The secret to this is offering a ‘service’ that is both affordable and enjoyable. This means reducing the house edge – the edge that the casino has over players – and increasing the turnover of bets. The latter is achieved by offering low margins on bets, lowering the minimum stakes and increasing the number of fixed-odds games.
