What is the evolution of the house edge, and do casinos always win?

Casinos are a mix of science, art, and psychology. The ones we know today are wonders of technology, and the math behind them and the house edges has become quite sophisticated, guaranteeing longevity and profitability.

Understanding the casino's house edge and history through the ages is essential to knowing how gaming mathematics developed alongside the rise of casinos and gambling in general. The roots of gambling stretch back to ancient cultures, all the way to the early dice games to around 3000 BC, where the element of chance was cherished.

An ancient saying states, "The house always wins," and this reflects a time-tested truth in the gambling world. Ancient China, Egypt, and Rome had their versions of games in which the odds were more a matter of intuition than mathematical certainty.

As gambling evolved in Europe specifically, the idea of creating a structured environment with clear benefits for the house started to become popular. The first recognised development occurred in the 17th century.

European casinos in the 17th century

To make sure you understand, we must begin with some Casinos 101 information.

Gambling began taking shape in Europe, particularly Italy and France, in the 17th century. Casino di Venezia, which opened in 1638 in Venice, is an example of the earliest casinos.

Roulette laid the groundwork for the modern understanding of the house edge. It was designed as a wheel with 36 numbered pockets, where players bet on numbers and colours, and the wheel would spin.

House edge reached popularity in the 19th century

During the 19th century, new games and betting systems were introduced to casinos with their own versions of the house edge. The house edge for games like blackjack and poker became clear as casinos began to optimise their games for profitability.

For example, in blackjack, the house edge occurred through rules such as the dealer's ability to act last and that ties resulted in no loss for the house.

Casino evolution and the refinement of the house edge

Las Vegas became the hub of American gambling in the 20th Century. During this massive expansion of casinos, the house edge became a more central part of the gambling world. The most notable change was the introduction of electronic slot machines in the 1960s.

These slot machines came with a built-in house edge due to the games' random number generators, which ensured the outcome of each spin was in favour of the casino in the long run.

During this time, there was an increased interest in video poker, where the house edge was lessened through strategies and pay tables, which would reward players for skilful play. The house edge for video poker could be reduced to as low as 0.5%, depending on the game and the player's knowledge of the particular game.

House edge in modern casinos

In our current casinos, the house edge is important in determining whether a casino will make a profit. Casinos constantly adjust the house edge through rule changes and new game variations to maintain a positive profit climb.

The house edge concept transcends traditional casinos, influencing sports betting and lotteries, amongst others. As technology evolves, you can be certain that the methods and complexity of house edge performance will also grow. There are exciting innovations for the future, but the foundational principles of gambling will remain.

Let’s look at some interesting facts about the house edge that show how it influences casino games and player strategy:

• House edge doesn’t mean that the casino wins every time – Players can have a lucky streak and win big, causing the house edge to become insignificant.
• Roulette’s house edge varies by version – The House Edge depends on the type of wheel, which varies between 1.35% and 5.26%.
• Casino design influences the house edge – The casino implements strategies to keep you comfortable for longer, like the positioning of tables, lighting, decor, and entertainment.

How to make the house edge work for you

Players are not destined to lose every time they play. It is important to note that the house edge is calculated over an extended period. Players can experience both wins and losses, and unpredictability keeps players engaged and excited.

Let's look at some strategies players can use to minimise the house edge:

The house edge can be a helpful tool for players, as it indicates which games tend to be the most profitable. Games with a high house edge generally pay out less compared to those with a lower house edge.

The house edge assists the casino as a commercial business in covering expenses, not only to maintain the casino but also to pay staff and the costs of the games. The casino's profit comes from the money the gamblers pay into the game.

Whether you are playing at a land-based gaming house or on an online casino platform, understanding the history of house edge is vital to appreciating the detailed balance between player skill and luck.
