Before we get cracking talking about numbers, house edge, and which games are more favorable to gamblers and punters alike rather than the house - we first need to truly understand what house edge is and how it works in lay ma terms.
What is house edge?
If you have not heard of the proverb, "the house always wins", you have probably been living a cave for most of your life. It is true! The house does always win. What is the house? Well, the house in the scenario refers to the casino. It can be a land based casino or a virtual online casino. The house may not always win every single hand or every single game, but eventually over the long run - the house does win! This is because all games in a casino are mathematically designed to achieve exactly this. A casino is a business at the end of the day and making money is unmistakably the motive!
The fact is that if casinos did not employ such mathematical strategies to give them the upper hand or the edge then they simply would not be able to carry on doing business, the casino would more or less become a charity which makes donations to anyone and everyone that comes in for a game. Furthermore, the casino has to make some money because even if not for the sake of profit, they still have to bear operational costs such as staff salary, electricity, real estate, wages, other bills, etc.
However, just because the house has the edge it does not mean every player will lose 10% (if the return to player percent was 90%). What it actually means is that in the long run, the house will return 90% of all of the money that has been gambled and keep 10% of all of the money that has been gambled.
Knowing this, you can now comprehend why it would be in your favor, as a casino game player, to get an idea of which game have the highest house edge and which ones have the lowest house edge. It is simple! The higher the house edge, the lesser your chance of winning big and the lower the house edge the higher your chances of winning big.
In other words, your odds of winning are inversely proportional to the house edge. So what you must be looking to do, from a strategic stand point, is to play more of the games where the house edge is low and avoid, as much as possible, the games where the house edge is too high.
