# Debunking Casino Myths: Understanding House Edge and Odds

## Casino games are a popular form of entertainment and gambling for millions of people around the world. However, there are also many myths and misconceptions that surround casino games and affect the way people play and perceive them.

Some of these myths are harmless, while others can lead to unrealistic expectations, poor decisions, or even addiction. As you read on, we will debunk some of the most common casino myths by explaining the concept of the house edge and odds, providing you with a clear understanding of how these factors influence your chances of winning. And ultimately, we will help you make more informed gambling decisions.

### What is House Edge?

House edge is the mathematical advantage that the casino has over the player in any given game. It is expressed as a percentage of the player’s initial bet that the casino expects to keep as profit in the long run.

For example, if a game has a house edge of 5%, it means that for every £100 wagered by the player, the casino expects to win £5 on average. House edge is not a fixed or constant value, but it varies depending on the game, the rules, and the strategy used by the player.

By comparing the actual odds of a game with its true odds, you can deduce the house edge of that game. True odds in this context are the probabilities of each possible outcome occurring, based on the laws of mathematics and probability. On the other hand, actual odds are the payouts that the casino offers to the winners, based on the game’s design and rules. The difference between the true odds and actual odds is what gives the casino its edge over the player.

For example, in roulette, there are 37 numbers on the wheel (0 to 36), and each number has an equal chance of being hit by the ball. Therefore, the true odds of any single number winning are 1 in 37, or 2.7%. However, if you bet on a single number and win, the casino will only pay you 35 to 1, or £35 for every £1 wagered. This means that the actual odds are 35 in 37, or 94.6%. The difference between the true odds and the actual odds is 2.7%, which is also the house edge for this bet.

### What are Odds?

Odds are another way of expressing the probability of an event occurring. They can be expressed as either fractional odds or decimal odds. Fractional odds show how much you will win relative to how much you bet, while decimal odds show how much you will win including your original stake. That is why to some extent, you should know how to read odds.

For example, if you bet £10 on a coin toss at fractional odds of 2/1 (or 3.0 in decimal), it means that you have a 50% chance of winning, and if you win, you will get £20 profit plus your £10 stake back, for a total return of £30. If you bet £10 on a coin toss at fractional odds of 1/2 (or 1.5 in decimal), it means that you have a 66.7% chance of winning, and if you win, you will get £5 profit plus your £10 stake back, for a total return of £15.
