Casino house edge – what’s up with that?

Even if you’re new to online gaming, you must have heard the term all over the web. But what does house edge mean in the gaming world?

Can you calculate the house edge? Is the house edge identical for all casino games?

The amount of questions is getting overwhelming.

Long story short, in the following article, you will learn the whole shebang about house edges. After reading, you will know what they mean in casino games and how and why they differ among game types.

What is House Edge?

House edge in gambling refers to the precedence that casinos have over gamblers.

Another term for the house edge is the house advantage. Perhaps this one describes the concept better than “edge”.

There are three main groups:

  • High house edge
  • Medium house edge
  • Low house edge

We aim to explain all three kinds and refer you to the one that works best for you.

High House Edge

High house edges are typically linked with high-risk games such as Keno and some slots. Ambitious players usually go for high house edges. Simply, the “high” attribute allows greater shots for the casino to win over you.

A high house edge goes hand-in-hand with games based on luck. When playing Keno or slots, there is little you can do to affect the outcome.

Slots can’t always be trusted due to their unstable volatility. With slots, software providers typically focus on the RTP value rather than the house edge. This approach can be misleading. That’s why you can always calculate the house edge.

Here’s how you can calculate the house edge in slots:

100% – RTP (Return to Player) = House Advantage

For instance, if a slot comes with a Return to Player estimation of 88.12%, the edge totals a whopping 11.88%. This example refers to Microgaming’s Mega Moolah jackpot slot.

On the other hand, there are slots with incredibly high RTPs, such as NetEnt’s Mega Joker (99%) and Jackpot 6,000 (98.90%).

Therefore, the house edge on slot machines swings between 1% and 15%.

Medium House Edge

If you are after a medium house edge game, your choice is limited to Roulette. If you play single zero Roulette (European Roulette), the house edge can go as low as 2.56%.

Generally speaking, any house edge value that goes below 3% is considered decent. However, Roulette can be tricky, so make sure you are applying the appropriate Roulette strategy. And always play European Roulette if you want to keep that house advantage small.

Low House Edge

This segment will be discussed in detail within the section “House Edge in Different Casino Games”.

Be that as it may, the house edge is a phrase as old as gambling itself. Casinos invented this notion to retain a portion of the stakes regardless of the outcome. To put it bluntly, casinos will always win. That’s the harsh truth. Nevertheless, you can reduce the casino’s funds and increase your own.

Knowing how the house edge works will help you develop the right house edge strategy. As a result, you can rely more on your knowledge than just pure luck. And this, our friend, makes a smart punter.

“Knowledge is power.”

―Francis Bacon

Once you understand the function of the house edge, you’ll know what casino game pays out the best.

What does House Edge Mean?

For many players, the house edge determines what casino game they will play. In the iGaming field, which is a combination of luck and logic, there are two types of players.

The first kind will play a certain casino game for its looks or mechanics. The second sort will solely follow logical thinking and consider only the house edge. Which one are you?

Those who find themselves in the middle of the two player profiles need to learn about the house edge. So, for everyone’s sake, let’s see how the house edge works.

The house edge matters because it dictates the tempo of the game. If you play a low house edge game, you can be more relaxed and don’t have to think as much. On the other side, high house edge titles require complete immersion and focus.

You can look at the house advantage as built-in profit that casinos reserve in case players get a lucky streak.

To exemplify, let’s take Roulette. If you play American (Double Zero) Roulette, the house advantage is 5.26%. Let’s see how we calculate this house edge. There are 38 pockets on the wheel. In other words, your chances of winning are one in 38. Place a €1 bet and the casino will pay you 35 for it. So at this point, you have your initial €1 plus €35 = €36. The total number of pockets is 38, minus €36; that makes it 2. Divide the €2 by 38 and you’ll get the casino advantage – 5.26%.
