The truth is that a lot depends on your chances of winning at an online casino. The casino, game type, game payout and bonus options all play an important role. If you want to get an overview of your chances of playing at online casinos, this article has you covered.

Understanding and Identifying Casino Odds

Knowing and learning the odds available in advance will prepare your mind for what is to come. Be sure to read the house edge and the odds and calculate them to be sure what to expect. Generally, any casino’s odds are based on the number of possible outcomes and the margin offered by your bookmaker on your bet.

The edge of the house

Take this myth to heart: the odds of casino players winning the money are higher and brighter than the odds of the players walking away with the casino money. The house edge represents the gross revenue a casino can potentially make from each game a player plays and bets on.

The fact is that casino games are designed to favor the house. The advantage is built into games to weaken the odds of payout. For example, one variation of roulette offers a house-to-player odds of 39:1, 38:1, or 37:1. Sometimes you can double or triple 00. Some games offer a house edge of up to 15% or 40%. Others offer a house edge of 5%, 2%, 2.5%, 1.4% or 0.5%.

Odds of winning at slot machines

The odds in slot machines are often against the player. They are usually randomly generated by a random number generator (RNG). Slot machines deal with payout ratios that often favor the house against the player. No matter your strategy. But you can look at the potential return to player to calculate your odds of winning at slots. You should check the title of the slot machine that pays the best prize money and what the payout percentage is. Some slot machines have a payout percentage of up to 98%. For example, a slot machine with a 98% payout means you have a chance of winning $98 on every $100 bet you make.

How to Calculate Fraction Odds

Generally, it is quite easy to identify and calculate fractional casino odds. This way you can know your odds of winning even before you bet. Fraction odds are in the form of a fraction, such as 8/1 (8:1), 39/1 (39:1), 5/2, (5:2), etc. This means that if you bet on the denominator, the numerator wins, and vice versa. In a game with odds of 39/1, if you bet on 1, then 8 wins. This means that you will win $39 on every $1 bet. It sounds simple, but in reality, it’s more technical than you might imagine. There are rules and strategies for winning any casino game, whether it’s a card game, a table game, or a slot machine.

How to Convert Fractional Odds to Probability

Although the space is sketchy and tricky, there are ways to calculate and convert your odds of winning from a fraction to a probability or a percentage. The method is quite simple and the same for fractional and American odds. Let’s use the 36/1 roulette odds and convert them to a percentage.

Symbolically, probability of winning = X/(X+Y)*100, where X and Y represent the numerator and denominator of fractional odds respectively. In our case, X=36 and Y=1.

Mathematically, odds of 37/1 = X/(37+1)*100 would give us 1/38*100=2.6%. Your probability of winning is 2.6% after conversion.


There is no doubt that newbie players have great doubts about the fairness of many online casinos. When you hear about the axiom that “the house always wins”, you may become reluctant to play casino games. In the end, you will find that there is a 50% chance of winning at an online casino. Both the player and the dealer have an equal winning or losing advantage. Once earned, players could spend to earn something like a Journey to Italie. Note that in gambling, nothing is left to chance.
