Slot Machine Odds Of Winning

Slot Machine Odds Of Winning

As far as the casino industry is concerned, slot machine games are the most played games, yet, they are the least understood.

A Bit of History on Physically Setting Odds. The random number generator (RNG) was developed for slot machines by Bally Technologies in 1984. About a decade later, most slot machines had this RNG, which allowed for easily adjustable odds of winning. There are three main factors to consider when deciding which are the best online slots games worth spending your hard-earned money on: the gameplay, the odds of winning and the host reputation. Finding an immersive gameplay experience is essential to get the most enjoyment out of any slots machine game.

  1. In all the modern slot machines the player's odds of hitting the winning combination of numbers and symbols would depend on how the reels are set up. Every stop on the reel can correspond to more than a single stop on the reel.
  2. What Are Odds of Winning in Slot Games. First of all you should know what odds of winning in slot games are. Odds of winning are displayed in percentages and they represent a percentage rate a slot machine pays back to a player. The bigger the percentage the higher odds of winning are. What that practically means?
  3. Some times of day are better than others. This isn’t true. Casinos aren’t able to reprogram the.

In the UK, slot machine games, also known as the fruit machine games, are some of the most sought after games at the land based casinos, and in the US, where they were first played in the 1890’s, they continue enjoying prominence and popularity among the players!

Australia, where they are referred to as Pokies, has more slots per capita than the US though, and while not at the same level as Australia, slot machine games continue to receive game time across different European countries and different gambling hotspots in Macau.

Online, hundreds of millions of bettors continue playing video slot machine games, as casual players through different social media application or for real cash at the different online casinos.

But even to those who have devoted their free time playing slots; the different slot terms, how they work, and the odds of winning the jackpots remain in the dark!

Is it possible to win playing slots jackpot?

The first and popular question that most of bettors ask is ‘Can I win the jackpot games?’ Right after this, they’ll ask ‘Is there a strategy or secret to winning big?’

It’s natural enough for any player to want to win! What’s the point of playing anyway? Is it not to experience the thrill and big wins that come with the video slot games?

Can I win while playing the jackpot slot games?

Sometimes, yes! All the payoffs as indicated on the video slot game actually represent your chance of winning. Any slots player who very often plays the game will increase his/her chances of winning and a reason to celebrate. But we are yet to see someone, besides the woman who won €1.75 million who while playing the same video slot game in a month, defied the odds of 625million:1 and won the same game twice in a row!

Is there a strategy or a secret to winning big?

Let nobody lie to you that they used a well worked out formula to win the video slot games! With rare cases, 99% of the slot machine games purely rely on chance. The results are determined by the Random Number Generator, and there’s nothing the casino or bettor can do to influence how the numbers are generated.

To this popular question, there isn’t any magical strategy or formula to increase your chances of winning! Only cross your fingers and pray lady luck is on your side!

What are the odds of winning a casino jackpot?

The odds of winning any casino jackpot vary from one game to another, on different coin values for the different bets you place, and in some cases on a slot machine game with the same denomination but playing on different machines. Casinos don’t usually advertise the odds of the different games and neither do they post them on the different machines.

Therefore, the best that we could do to estimate the odds of winning the different jackpot is to compare different games, offered at different casinos. For the estimate, we focused our attention on the United Kingdom market, where the casino average payouts are made public by the UK Gambling Commission for bettors to see.

The percentages are different from one casino to another but the overall look of the paybacks look like this: Slot machines normally pay higher percentages if you place bigger bets. Below are some average house edges and returns, based on the information that we gathered from the UK Gambling Commission.

Odds Of Winning On Slots

Take note that the percentage of bets returned to the bettor as winnings increase as the size of the bet gets bigger. Gamblers who choose to go for the more expensive jackpot games get a larger portion of their wager back, and also stand a better chance of winning.

Does this mean that players should focus on placing bigger bets? No! By playing the more expensive game and get a larger portion of the bets you place back, but at the end of it, lose more money as you’ll be taking a bigger risk. The best thing to do is to let your bankroll guide you, and also avoid betting more money than you can afford.

Modern Video Slot Odds

Most of the modernised slot machines don’t have 10 numbers on each reel and most of the slot games, both at the online and land based casinos, have at least five reels as opposed to the traditional three reels. This means that the developers and programmers are always dealing with more complex machines, featuring hundreds if not thousands of stops, symbols or random numbers on each reel.

Below are some of the factors that are always considered when modern video slot odds are determined:

  • When the slot machines are on video, the programmer can choose to make the reels as long as he/she needs them to be. If for example, to achieve the right odds the programmer requires a slot reel to feature a sequence of 1000 symbols, then he/she will have to program a 1,000 symbol reel.
  • However, in the land-based casinos, it difficult for the programmer to fit the 1000 symbols in the mechanical slot machines. Therefore to achieve this, the programmers use what is referred to as the ‘Virtual Reel’. Thanks to this feature, the slot machines at the brick and mortar casinos with the small reels can act as if they have more symbols. For example, the programmer could tell the machine ‘Any time the RNG software stops on number 7, stop on the jackpot symbol. Any time it stops on numbers 5, 3, 1 or 9, stop on the first bar.’ By programming the machine this way, the highly sought symbol that triggers the jackpot can only appear once after several hundred or thousands spins. This plays a huge role in determining the odds of the jackpot. A good example was in 2003 when the world record jackpot of Megabucks machine paid out a mind-blowing $39 million. According to IGT, the company behind this game, the odds of winning the jackpot were approximately 1 in 50 million.

The Free Spins & Bonus Factor

Almost all the modern video slot games, including jackpots, have bonus events which come in different forms including the spinning of a bonus wheel as with Mega Millions; Pick’em bonuses as seen in Jackpot Party and you can check out free spins on our favourite sites at a number of highly recommended online casino operators.

During the bonus round, you have the chance of accumulating credits without spending any extra cash thanks to the in-game free spins bonus round. This has to account for while setting the game’s odds and paybacks during the regular reel spins. But how do the free spins contribute to the game’s overall jackpot?

One of my friend, who happens to be a programmer told me that one of the games he has developed has a 90% RTP; 60% of this comes from the general reel spins, 30% comes from the different in-game bonuses, including the free spins and the remaining 10% comes from the house.

So how do you increase your odds of winning the casino jackpot?

Below are rules of thumb that every bettor should follow to increase their chance of winning while playing video slot games.

  • Always choose games that you understand better
  • Make the most of the casino bonuses and offers to boost your bankroll. Most sites powered by NetEnt have free spins offers and deposit offers
  • To ensure that your bankroll goes further, reduce the number of coins that you bet on each line and increase the number of paylines. This increase your chances of winning the bet

How do odds work in slot machines? Unlike some other games, they’re fixed. However you play, the odds of winning do not go up or down, but always stay the same.

Payout odds vary based on the machine. Two slot machines may look identical, yet may have different odds. So you can’t tell by the appearance of the machine.

The odds of hitting the top award vary greatly by machine, and may be as low as one in 17,000,000 spins – comparable to winning Lotto 6/49.


Over the long run, the machine is guaranteed to make money.

Slot Payouts

How To Pick A Winning Slot Machine


When playing slots, knowing the payback or payout percentage of various machines can help you understand your chances of winning.

  • Every slot machine arrives from the manufacturer with a computer chip capable of pre-determining how much of the overall player spend the machine will pay back to players over its lifetime. Machines are set by the casino, also known as the house, to payback a certain percentage of coins played, including paying out the jackpot
  • The pre-programmed amount that the house keeps is called the hold

The payback percentage, regulated by the Alcohol and Gaming Commission of Ontario (AGCO), is: Minimum: 85%

The payback percentage is meant to be representative of the machine’s entire lifecycle, which can be many millions of spins. When the payback percentage is 85%, this doesn’t mean that you can expect to win back $85 if you gamble $100 on that individual session.

The payback percentage doesn’t affect the short-term. Because of randomness, anything can happen when you play.

Compared to other casino games, slots favour the house more.

Payouts of different machines

Slot Machines With Best Odds Of Winning

It's easy to think the higher the “denomination”, the more a machine pays out - for example, that a dollar machine will pay more than quarter machines. In Ontario, this isn't always the case. Rummy rules. Always check the paytable to know what a machine pays out.

OLG doesn’t have complete control over the payouts of slot machines. This is regulated by the Alcohol and Gaming Commission of Ontario (AGCO).

Casinos are not allowed to change a machine’s payout while someone is playing or winning on them, nor can they adjust machines during weekends.
