The House Edge for Blackjack and Other Casino Games

Casino House Edge Thumbnail

We all know that heading down to the casino or loading up an online version on our phones can be a whole lot of fun. Of course, winning is a big part of the experience. Generally, a happier gambling experience is one that is followed by some monetary rewards. But how do we know which games pay better than others? It’s actually quite simple. The lower the house edge the game offers, the better chance you have of winning cash when playing the title. For this, reason, this helpful guide will introduce you to blackjack house edge and return-to-player ratios on most of the popular casino games you can play on both land-based floors and online casino platforms.

Casino House Edge

In simple terms, the house edge is the profit that a casino stands to make from a game. It is based on a percentage of the player’s original bet. It is the mathematical advantage that the casino has over the player each time a hand/round is played. For instance, if a gamer plays a slot machine with a house edge of 5%, the casino expects that it will make an average profit of 5c for every $1 the person spends on the machine.

The calculation is formulated by a complicated mathematical equation: HOUSE EDGE = (Odds against success – house odds) x probability (percentage) of success. It is always important to know that in the long run, the house always wins. However, there are many lucky players that walk away winners. While some of the wins do come from high-house edge games, more consistent ones come from low-house edge titles.

What is Return to Player (RTP)?

Many casinos tend to focus on presenting players with return-to-player ratios (RTPs) as they seem a lot more impressive than house edge figures. If you do not know how to read them properly, it seems that the odds are ever in your favor. RTP is the percentage of wagers that customers will be paid out over a long period of time.

A 96% RTP on a slot game seems impressive until you realize that someone else may walk away with a win in the future at your cost. The remaining 3% is the house edge. This is what the machines stand to make in average profits from your wagers. But because some games payout big jackpots, the likelihood of landing rewards each time you play a game is slim.

The House Edge of Various Casino Games

Now it is pertinent to know that games that involve skill and decision-making usually have much lower house edge statistics. This means that if you learn to play them properly you have a better chance of winning than if you were playing a game of chance. That’s why Blackjack’s house edge is quite a bit better than roulette’s house edge and is far better than slot machine stats.

The house carries the edge in blackjack for two main reasons. Firstly, the player goes first and could go bust before the dealer even begins. Secondly, one of the dealer’s cards is hidden from the table, so players don’t know what hand they are trying to beat.


Roulette Wheel


Roulette is one of the most popular casino table games in the world. The number of different betting options and odds makes it a game for both high rollers and low-risk takers alike. There are two prominent games, namely European Roulette or American Roulette. The American wheel has an extra pocket (00) on the turn style which lowers your chances of winning.

The roulette statistic tables below not only show you the house edge, but also the odds paid on various bets and the probability of landing rewards playing those options.

As you can clearly see, your less risky bets involve almost a 50/50 chance of doubling your money. This is a similar payout to what you can expect when playing Blackjack and winning. However, if the Blackjack house edge lands in your favor and you win with a natural blackjack hand, you can extend those odds to 3:2. Of course, placing straight-up bets on roulette will multiply your wager by 35x. The higher the payout, the less likely it is you will land it.

Throwing dice in craps


Craps is an American favorite. The sheer number of betting combinations makes it a hot game on the Vegas floor. You can choose to make craps as simple or as complicated as you want to by choosing between single-dice roll outcomes or multi-roll outcomes. It’s more difficult to succeed playing single-bet outcomes, so the house edge is far higher, yet the payout odds are certainly more attractive.

In the table below we will display the kind of bet, the payout range on the bet, and the house edge range on the bet. You may be wondering why there is a Craps House edge range instead of a fixed rate. That’s because different casinos set different odds. As such, be aware of the table rules before you cast your lots.

2 and 12 and all hard hop bets 29:1 to 33:1 5.56% to 16.67%
3 and 11 and all easy hop bets 14:1 to 16:1 5.56% to 16.67%
Any craps (2 or 3 or 12) 7:1 to 7.5:1 5.56% to 11.11%
Any seven 4:1 16.67%

Multi-Roll bets obviously grant you a better chance of landing a win. Here, the house edge can be deciphered in three different ways: For the bet made, for the bet resolved, and for the house edge per roll. Most people concentrate more on the House Edge per bet resolved statistic to gauge the risk involved in the wager.

But there are various games of poker to take into regard when it comes to choosing your seat at the table. They are all based loosely on the same poker hands, but with variances in the gameplay mechanics. Below is a table showing all the popular forms of casino poker along with their RTP and house edge stats.

A set wager limit could win you anything from a 1:1 payoff to thousands of times your stake with the jackpot machines. There are various forms of video poker. Look to the table below to find which one offers the best returns for you.

However, you really need to know your business to make the right calls on every hand and take advantage of the odds. Most video poker players don’t.

Slot Reel


Slot machines are by far the most popular games in the world. The ease of popping in credits and rolling a reel is obviously an attraction for many. Of course, the bonus rounds and special features are also a big drawcard. But slots are games of chance. No degree of skill can help you win a dime. As such, they have some of the highest house edge statistics of any other casino game (bar maybe scratch cards and Keno). Where the Blackjack house edge is near 0.5%, the very best you’ll get out of a slot is 1%, but that is extremely rare. Most of them are around 4% or worse.

Land-based slots are stingier than their online counterparts. That’s because retail casinos must pay utilities and overheads. The costs at online casinos are minimal in comparison. As such, we recommend playing on your desktop or mobile device if you fancy a spin of the reels. Explore the average RTP and house edge of slots in the table below.

Slot Type RTP House Edge
Land-Based Slots 75% – 94% (86% Ave) 25% – 6% (Ave 14%)
Online Slots 88% – 99% (96% Ave) 12% – 1% (4% Ave)
