Understanding the odds in top games

Casino games are not about luck alone. Probability and logical math play a key role in determining the outcome of a game.

Whether drawing a card or spinning the slot reels, your chances of winning depend on the probability of getting a specific result.

As such, understanding probability can help you make informed decisions and give you an edge during your next casino endeavor.

So, let’s see how probability works in popular casino games.


The House edge in online casino games

Traditional casinos and online sweepstakes casinos are fundamentally businesses. While providing fun and entertainment to the players, they are meant to make profits. This is where they utilize a mathematical concept called house edge.

House edge is an advantage casinos have in any game. It represents the percentage of each bet placed by players that the casino expects to retain. House edge varies with each casino game. The lower the house edge, the better the odds for players.

Understanding this concept can help you make informed decisions about which game to bet on and improve your chances of winning.


How to calculate the odds of a casino game?

Odds are all about probability. To estimate the odds of winning your bet in any casino game, it is essential to know the number of probable outcomes that will generate a win and the total number of probable outcomes.

For instance, when you toss a coin, there are only two potential outcomes: heads or tails. Therefore, if you bet on heads, the odds of winning will be 1 in 2 or 50%.

Let’s see what odds some popular casino games have to offer.


Winning a game of Blackjack focuses on getting a total higher than the dealer’s hand without going over 21.

The chances of obtaining a Blackjack are the number of ways we can draw two cards from a deck to reach 21.

Calculating the odds while using a single deck is easier. You can win with just two cards when you have an Ace and 10 that adds up to 21, and a single deck of cards has 16 10s and 4 Aces.

So, the probability of getting a blackjack is about 4.8%.

When playing with two decks, the proportion of each number remains the same, but the chances of getting a specific outcome are reduced. Why?

Removing a card from 104 cards does not impact it as much as removing one from 52 cards. So, when multiple desks are used, the probability of winning the game changes.

The chances of getting no bust are 26.5%, while percentages for ‘standing’ and ‘decision’ hands are 30% and 38.7%, respectively.


A game of Roulette involves a spinning wheel with pockets representing numbers where the ball should land.

The American version of Roulette has 38 pockets, while the European one has 37, but the odds for each version remain the same.

The chances of winning a straight bet in Roulette, that is, the ball landing on a specific number, is 1 in 38 or 37, depending on the version.

That is why betting on split, street, and corner range of numbers increases the odds of winning.

When you bet on a red or black, the probability becomes almost 50%. The same goes for betting on an even or odd number.

Slot machine

Slot machines have a built-in microchip called Random Number Generator (RNG), where each number represents a specific position of reels on the pay line.

The number of reel positions in a machine can be determined by the number of reels and the number of symbols on each reel.

For instance, if a machine has 3 reels with 25 symbols each, the maximum number of combinations will be 253, which equals 15,625.

Only one combination from 15,625 results will win as the RNG for this slot machine will rotate between 1 and 15,625. As such, the odds for players while playing slots are low.

So, the best strategy for winning in a slot machine is to play the maximum possible coins allowed in it.

Moreover, every slot machine game offers a payout percentage to pick the one that provides better rewards.

Wrapping Up

Understanding the probability behind casino games can significantly improve your chances of winning a bet.

Considering the house edge and calculating the odds in Blackjack, Roulette, Slots, or any other casino game can help you build a winning strategy and add depth to your gaming experience.
