Odds and House Edge

Beating The House: Know Odds

Odds and house edge matter in online casino gaming. They affect your decisions and chances of winning. This guide explains odds and house edge and how they differ in different games. It also gives tips to make your gaming experience better.

Before diving into the specifics, let’s establish a foundation for the key terms:

  • Odds: The probability that an event will occur. In casino games, odds are used to calculate potential payouts and understand the likelihood of winning a particular bet.
  • House Edge: The advantage that the casino has over players in any given game. It represents the percentage of each bet that the casino expects to keep over time.

Understanding Odds

Odds indicate the chance of a specific result happening during a game. They indicate the potential payout for a successful bet and are commonly presented in different forms.

Types of Odds

There are three primary types of odds used in online casinos:

  • Decimal Odds: Commonly used in Australia and most other parts of the world, decimal odds are easy to understand. They represent the total payout, including the initial stake, for a successful bet.
  • Fractional Odds: More common in the UK, fractional odds show the potential profit relative to the stake. For example, 3/1 odds mean you can win three times your stake.
  • American Odds (Moneyline): Popular in the US, American odds indicate how much you need to wager to win a specific amount (for negative odds) or how much you would win from a specific wager (for positive odds).

How Odds Work in Casino Games

The potential payouts for different bets in casino games are determined by the odds. These odds differ depending on the type of bet made, such as a single number bet or a red/black bet in roulette. Being aware of the odds can assist in selecting bets that strike a good balance between risk and reward.

Factors Affecting Odds

Several factors influence odds in casino games:

  • Game rules and variations: Different variations of a game can affect the odds and payouts. For example, American roulette has a higher house edge than European roulette due to the presence of an extra zero.
  • Player decisions and strategies: In games like blackjack and video poker, player decisions can impact the odds. Utilizing optimal strategies can help improve your chances of winning.

Unpacking House Edge

The casino’s advantage over players in a particular game is known as the house edge. This is typically shown as a percentage of every wager that the casino anticipates keeping in the long run. For example, if a game has a house edge of 5%, the casino expects to hold onto 5% of all wagers made.

Role of House Edge in Casino Games

The casino’s profitability is maintained over time through the use of a built-in advantage known as the house edge. This advantage differs among games and may even vary within various versions of the same game.

Calculating House Edge in Different Games

Let’s explore the house edge in some popular casino games:

  • Slots: The house edge in slots is often expressed as the Return to Player (RTP), which indicates the percentage of wagers returned to players over time. Slots typically have an RTP ranging from 90% to 98%, meaning the house edge is 2-10%.
  • Table Games: In blackjack, the house edge can vary from as low as 0.5% to higher depending on the variation and the player’s strategy. In roulette, American roulette has a house edge of 5.26%, while European roulette has a lower house edge of 2.7%.
  • Video Poker: The house edge in video poker varies depending on the paytable and the player’s strategy. Optimal play can reduce the house edge to less than 1%.

How the House Edge Impacts Players’ Chances of Winning

The casino has a better chance of winning when the house edge is higher, making it harder for players to win. On the other hand, when the house edge is lower, players have a better chance of winning and have a more enjoyable gaming experience.

Game-Specific Guides

Let’s take a closer look at the odds and house edge for some popular casino games and provide strategies for maximizing player advantage:


  • Explaining Return to Player (RTP) and Variance: RTP is the percentage of wagers returned to players over time, while variance refers to the risk and frequency of payouts. High RTP and low variance slots offer a steady stream of smaller wins, while low RTP and high variance slots offer larger, less frequent wins.
  • Strategies for Finding Slots with the Best Odds: Look for slots with high RTP (above 95%) for better chances of winning. Research the paytable and game features to understand how they impact payouts.
  • Understanding How Different Slot Features Affect House Edge: Features such as multipliers, wilds, and bonus rounds can influence payouts and RTP.


  • Basic Strategy for Minimizing House Edge: Basic strategy charts guide players on the best decisions based on their hand and the dealer’s up card, minimizing the house edge to as low as 0.5%.
  • Card Counting and Its Impact on Odds: Advanced players can use card counting techniques to track high and low cards, adjusting their bets accordingly to gain an edge over the house.
  • Variations of Blackjack and How They Influence House Edge: Different rules, such as the number of decks and dealer hit/stand policies, can affect the house edge.


  • American vs. European Roulette: American roulette features an extra zero (00), increasing the house edge to 5.26%. European roulette has a single zero, resulting in a lower house edge of 2.7%.
  • Strategies for Managing Bets and Minimizing House Edge: Betting on even-money options (red/black, odd/even) can offer more consistent results, while avoiding single number bets reduces risk.


  • Banker, Player, and Tie Bets: The banker bet has the lowest house edge (around 1.06%), followed by the player bet (1.24%). The tie bet has a high house edge (around 14%), making it risky.
  • Tips for Optimizing Baccarat Strategy: Stick with the banker bet for the best odds and avoid the tie bet.

Video Poker

  • Finding the Best Paytables for Higher RTP: Pay attention to the paytable to find games with favorable payouts and high RTP.
  • Utilizing Strategy Charts for Video Poker: Using strategy charts can help you make optimal decisions and reduce the house edge.

Managing Risk

Bankroll Management Tips

Managing your bankroll is essential for maintaining a healthy gambling experience:

  • Set a budget and stick to it.
  • Divide your bankroll into sessions and avoid chasing losses.
  • Use small portions of your bankroll for each bet.

Setting Limits to Minimize Losses

Establish both win and loss limits for every session. Once you hit your designated win limit, think about collecting your winnings. If you reach your pre-determined loss limit, take a break and leave the game.
