The House Edge: A Comprehensive Guide to Casino Game Probability

Introduction

Casinos are designed to be profitable, and one of the key factors that contribute to their success is the house edge. The house edge is the built-in advantage that casinos have over players in various games, ensuring that they make a profit in the long run. In this article, we’ll delve into the concept of the house edge, its significance, and how it affects different casino games.

What is the House Edge?

The house edge is the percentage of each bet that the casino expects to win over time. It’s the difference between the true odds of a game and the odds offered by the casino. The house edge is usually expressed as a decimal or percentage, and it varies from game to game.

Types of House Edge

There are two types of house edge: the theoretical house edge and the actual house edge.

• Theoretical House Edge: This is the house edge that’s built into a game based on its rules and probability. It’s the edge that the casino expects to win over an infinite number of hands or spins.
• Actual House Edge: This is the house edge that’s observed in real-world casino games. It can be higher or lower than the theoretical house edge due to factors like card counting, betting strategies, and the casino’s rules.
