December 01, 2020

Everything you need to know about a casino's house edge is in detailed explanation. Understand the house edge and choose the most profitable site to play at.

Most of us know that going to the casino is risky and the old-fashioned saying "The house always wins" seems to be true. All of that can be explained with House Edge.

What is House Edge?

House Edge plays an important role for the house at casinos. Although casino games are largely based on luck, there’s one rule that applies to all of them: it is House Edge. And the saying "The house always wins" seems to be true in all cases.

Obviously, casinos must maintain this advantage. Casinos are places where players come to gamble, of course, casinos need to make sure they can't lose constantly, of course, no matter what, they need to stay in business. In other words, they need to have an edge over the players. In fact, each game has a different House Edge.

For example, if you put $ 100 in a slot, there's a chance the casino will make $ 4 profit from you. Even if you win on that particular time, the casino will beat the majority of the other players, grabbing $4 from most of them. And the saying "The house always wins" seems to be true in all cases.

However, House Edge does not mean you can't win casino games. In fact, there have been tens of millions of winners even if the game they were playing had a high House Edge. Hence, House Edge just means the casino will be making money long enough from many other players.

Difference Between RTP (Returns to Player) and HE (House Edge)

RTP stands for Return to Player. It is the money that is returned to you after you have placed your bet. For example, if you bet $ 100 on a slot with an RTP of 96.8%. Theoretically, the profit would be 96.8 dollars but in the long run.

However, if you think you are guaranteed $ 96.8 back from every $ 100, you're wrong. You can easily lose $ 100 in a single play. As a result, you can only understand that $97 of it is being returned at some point to someone. There could be one lucky player who gets $ 968 while dozens of players lose $ 1,000 in total.

Simply put, RTP and HE are two sides of the same coin. Since RTP reflects the total stake returned, it is easy to calculate HE by subtracting the RTP from 100%. 

For example, a slot has a theoretical RTP of 96.8%. From there, we can calculate HE by subtracting the RTP from 100%, in this example, we have HE of 3.2%.
