What Is a House Edge?

In the world of online gaming, the house edge simply refers to the advantage that the casino has over players. Usually, you’ll come across it expressed as a percentage, for instance – 5%, 10%, etc. Of course, every casino is different and you should always do your research first. Naturally, the bigger the house edge, the more you will lose. Hence why you should seek a top Canadian online casino with a lower edge percentage than its competitors. This percentage is what you can expect to lose to the casino. 

Although every time you play the operator gets to keep a part of your investment, you can also expect some returns. The RTP, or ‘Return to Player’ coefficient will help you gauge the size of your rewards in the long run. This figure also comes in the form of a percentage and the higher it is, the better.

Finding the House Edge

It is essential to understand what the odds are before playing any casino game, like for instance roulette or online slots. So of course, knowing how to calculate the casino house edge is an indispensable skill. Actually, doing so is not too complicated at all. All you need to do is follow a simple formula and do the calculations. Here’s the formula: 

  • House Edge = (Odds against Success – House Odds) x Probability of Success

The odds against success value here is simply the number of ways to lose divided by the number of ways to win. So if we’re playing French roulette and making a straight bet, then this value is 36/1 since out of 37 pockets, we can win only if the ball lands in the 1 we chose. For this very reason, in this case, our probability of success is 1 in 37, and so on.

If you want the edge value expressed as a percentage, then simply calculate: 

  • House Percentage = House Edge x 100

Various Casino Games and Their House Edge

An important factor in the size of the casino advantage is the type of casino game you choose to play. Needless to say, some games offer better playing conditions than others. Here’s a quick rundown of the basics:

Crapsup to 16.67%

House Edge In Slots

Unfortunately, there is an unwritten rule in online gambling – the easier the game, the worse the odds. For instance, online slots are one of the most popular and easy-to-play casino games but the odds are not great. Usually, you can expect to win approximately between 2 and 15% of the time. 

There’s nothing online casino operators love more than a game that generates cash most of the time. In fact, that’s why there are so many slots to choose from. Operators can ensure speedy profits by cycling the game between tight and loose. So let’s say you want to wager $100 on a game with a 25% house edge. In this case, you can expect to lose $25 although that won’t necessarily happen.
