It’ll come as no surprise to you that online casinos are there to make money. In fact, the biggest online casinos in the world make millions and millions every year. Not all games contribute evenly to a casino’s profits though, as some manage to skim more money from players than others. On this page, we’re going to be taking a look at the games online casinos make the most money on.
A quick note first though: we’re not going to be looking at overall profits. If we were simply looking at which game contributed most to a casino’s coffers, the number one contributor would be slots, without any doubt. Instead, we’re going to look at profit as a percentage of the money spent on a game. This effectively means we’ll be using the house edge for this list – the higher the house edge, the more the game earns.
The game with the biggest house edge in most online casinos in keno, which is why experienced gamblers give it a wide berth all the time. Sure, it’s a really enjoyable game to play, but the average house edge of around 15% means that the casino takes £15 from every £100 wagered. This is a huge amount when compared to other games. So, if everyone decided to start playing keno, the online casinos would be exceptionally happy!
We’re singling out American roulette here, simply because casinos make more money from this version of the game than any others. The house edge at American roulette is 5.26%, so the casino wins, on average, £5.26 for every £100 spent. The reason American roulette has a higher house edge than others is the double-zero on the wheel, which gives players a lower chance of winning when placing even-money bets.
It’s tough to choose where to place slots, as the house edge can vary so much. On average though, you’ll find that slots have a house edge of around 4%, however you should check this before you start spinning the reels of any virtual machine. Please remember that you’ll often find that progressive slots actually have the highest house edges, so despite the potentially massive prizes, experienced players will often avoid them.
We’re putting blackjack here, even though the house edge is actually very low, coming in at around 1%. Why are we doing this? Well, blackjack is a game of skill, and this 1% house edge only applies to those who play perfectly throughout their entire playing session – something that only a very small percentage of people can do. Most will not play optimal strategy, and this means that the house edge gets considerably bigger.
French roulette has a slightly lower house edge than European roulette, however we’re putting them in the same category here. If you play these games perfectly – by this, we mean only ever placing even-money bets – you’ll find that European roulette has a house edge of 2.70%, while French roulette has a house edge of 1.35%. If you want the best chance to win money straightaway, we’d therefore recommend French roulette to you.
There you have it – details of which games make casinos the most money. What you should learn is this: the games with the highest house edges are most lucrative for casinos, and they are also the games you should avoid. Pick a game with a low house edge and you’ll always give yourself the best chance possible of beating the casino.
