How casinos work

Casinos work to one basic premise - the odds are mathematically in the favour of the house. Read our guide to see which games give you the best chance of winning.

Unlike sports betting, where the greater knowledge of the punter means he can beat the bookmaker over the long term, in a casino it is purely probability that provides the house edge.

However, this does not mean that a player cannot win. In the short term, quite the opposite. Given the low house edge on games such as roulette and blackjack, it is very possible to win money from casinos on a good night.

Roulette and blackjack

For example, the house edge in Roulette is just 2.7%. This means that for every £1 that you stake, on average you can expect to lose just 2.7p.

Put another way, betting on red or black pays out even money. The only house edge is the green zero, which is 1 number out of 37.

The thing about Roulette is that whatever bet you place, you'll be playing to a 2.7% margin. Games such as Blackjack and video poker are different in that they require player decisions and so strategies can be employed.

In Blackjack it is possible to keep taking cards, known hitting, until you bust, and to do this every hand. As such the house will have a 100% margin, or in other terms you will lose every single penny of your stakes.

Alternatively if you play to perfect Blackjack Strategy, you can wager your money at a margin of just 0.5%.
