How to Win at Slot Machines

Last updated: October 13, 2023

Here you will find our slots guide on how to win at slot machines, collated and prepared by our team of gambling experts and aficionados at Casino Today. Plus, we will also share some easy to implement strategies that will help players, just like you, to improve the chances of winning on slot machines overall.

An Introduction to Slot Machines

Before we get stuck into this how to win on slot machines guide, we want to start with something that should probably be well-known amongst all players, regardless of whether you are a newbie or a seasoned player.

All slot machines at both online casinos or brick and mortar casinos – are entirely chance-based.

This means that no matter what you may already think, there is no sure way to guarantee that you will win when playing slot machines. However, there are some tried and true methods that players with the know-how use to improve their chances of winning and maximizing their opportunity.

Like we’ve mentioned, in reality, there is no one strategy to follow when playing the slots as they are randomly generated outcomes.

Continue reading, and we will share with you an insight into how slot machines operate, plus what players can do to be fully informed when making decisions on what slot game to play and how best to play to win.

Just don’t forget to take everything with a pinch of salt, as with all casino gambling games – there will always be a house edge that favors the casino.

Slot Machines and The House Edge

All casino games include a house edge, and this is essentially the advantage that the casino (whether online or downtown) has over players.

In terms of slot machines, this edge is factored into the algorithm that the software developer created to operate as the random number generator, which determines the random outcomes on every spin.

The house edge is not the same among all casino games, though. The edge will vary between different variations of your favorite casino games. For table and card games, they may also vary depending on which state you are playing at (or which online casino).

Now, although we cannot give you a specific percentage for the house edge for all casino games, we can use a general example to explain this to you.

When playing slot machine games, the house edge can be different depending on how you play. What we mean by this is that as you change the number of pay lines or the number of credits (or commonly referred to as coins) that you pay per bet, the house edge will change too.

In short, this is because when players are playing across more pay lines, there are more opportunities to win.

For example, if you were trying to win at a typical slot machine game and you were making spins that cost 1c per spin, you could reasonably expect the house edge to be about 15%. However, if you increased the number of pay lines to a point where your bet per spin was 25c – you could expect the house edge to drop significantly to 8%.

If you were to raise the bet for your spins higher, say to a point where you were placing spins that were costing you $1 per spin, then the house edge might be as low as 6%.

To help this make more sense to you, consider thinking about the house edge across a period of play. Say you were playing your favorite slot game throughout one hour while playing for this hour, you were making $1 spins – with this example, we would consider that after the hour you would have spent $100. So, with a 6% house edge, a player would (on average) expect to have lost about $6 to the casino (i.e., spent $100 and won $94 back).

Typically, the house edge in slots is higher than most table or card games. European roulette, for example (the variant with just the one zero), has a house edge of approximately 2.5%, whereas American roulette (the two zeroes variant) has an increased house edge at 5.25%.

Comparing Slots Odds and Paylines

Players must note that although the odds of hitting a win across a particular pay line may have a mathematical chance of occurring, the casino will always feature that slight (sometimes not so slight!) advantage.

With the foundation of slots being random number generators, no two spins are linked, and there are endless possibilities.

When we look back at the very first slot machines, we can appreciate that they had the one pay line across three reals that each included ten symbols. Therefore, with 30 total symbols, there would be a total number of 1,000 possibilities.

Over the years, the number of symbols increased on these slot machines; thus, the combination possibilities blew out to significant outcomes like the 64,000 for three-reel slots with 40 symbols on each.

With the development of video slots, that figure grew exponentially. It is widely considered that most modern slot machines will have between 1 million and 50 million total combinations. While we would like to say it stopped there, with the latest innovations for five-reel video slots having 100 symbols per wheel, meaning players end up with a potent combination of over 10 billion outcomes!

Modern Slot Machines

When compared with the original mechanical slot games, the modern video slots are unrecognizable to those machines of the 1890s and early 1900s.

Developments in technology have meant that pay lines and ways-to-win have grown exponentially with casino games. When you include these increases with the innovative changes to bonus rounds and unique features that are also included in many of the top slots today, it is no wonder that we see even the smaller jackpots reaching significant figures.

For players today, the modern slot machines and games are a far cry from their original predecessors. As developers changed the way we win at slots, the games themselves changed, too, including all the bells and whistles that keep players coming back for more.

Some of the components which are relatively new to the slots are improved animations and graphics, unique features, and bonus rounds, including game components separate to the spinning of reels, as well as the much loved progressive jackpots.

Plus, with online casinos growing significantly, it is no doubt that players can expect more changes to come.

Random Number Generators

As we mentioned earlier, all slot machines are developed upon the foundation that they are mostly a random number generator (if you are still confused over this think of it as a random outcome generator).

While the original slot machines were limited in their outcomes, primarily because they were mechanical by nature – the developments we have seen over the years with video slots and online slots have allowed the game to grow through increased payline variations and win potentials.

With computing technology forever increasing, it is evident that video slots will never have a limit to their potential. This sounds very lucrative for casino owners; however, from the perspective of players, we would hope that this means more innovation in terms of entertainment and opportunistic features (similar to the old banked bonuses – which we will touch on later).

This was all made possible through the development of RNG’s. What RNG did for the slots was open up the possibilities for endless potential and a real gamble on the spin’s outcome. But, with this increase in pay lines, it added another layer to the varying degree of payout amounts.

It is interesting to think of where slot machines are at today and compare them to the original machines, which were a one-trick pony – allowing players to test their luck to win a single jackpot. Nowadays, there are so many ways to win that many wins are less than the bet placed on the spin.

Programmable and Random Slot Machines

More prominent in the modern age than ever before is the manufacture processes and potential of factories and companies. Companies can now mass produce items and with making minor changes – which is essentially the same thing with casino slot games.

These games are arguably the most popular casino pastime in the world, which makes it odd when you think that they are all the same game – except with slight changes to how it looks and acts.

Slots are just like smartphones, companies like Apple and Samsung just keep pumping them out, and each time they change just enough to make you want to buy them!

With the slot machines and games, they are all fundamentally the same game, just with a different skin over the top. This allows casinos and software developers the opportunity to provide players with a seemingly never-ending supply of games, each with different payouts, pay lines, and special features – thus catering to the demands of players without breaking the bank for research and development.

What this also means is that these games can also be developed with a specific payout percentage in mind, because while these games are RNG’s, the developers do have control over the range at which these payouts are pushed through.

This is an exciting concept because we know slots are random; however, at the same time, they are pre-determined or programmed to behave in a certain way.

Programmable Games

Following on from what we discussed previously when you think about increasing your chances of winning at slots, the strategies that players can implement are significantly few and far between – because the software developers have the power to program and predetermine the parameters at which the RNG operates.

But really, it is their game, so what would you expect? Casinos are just like every other business, too – they want to make money.

So, with the programmable nature of slot games, developers program or write the house edge into the code or otherwise the algorithm. Ultimately setting the tone for the casino and deciding the players’ fate well before they’ve taken their first spin.

The Spinning Wheel Machines

The original slot machines were mechanical, which is why they were also referred to as spinning wheel machines or drum machines (because the wheel inside was similar to a spinning drum). When they initially were launched, they were a massive hit with casinos thanks to their simple nature.

Insert coin, spin, hope for a jackpot.

Which is, for the most part, the attraction that players still have for slots today.

Although these spinning wheel machines are long gone from casinos today, players are still fond of their aesthetics. Similar to the popularity of classic three-reel slots with video slots players.

The fascination players have with these machines, and the slow ticking sounds that are accompanied by watching the last symbols land on the reel is timeless – and an aspect that many developers continue to cater to.

But, this has us thinking about payouts and those which are less than the cost of a spin.

If only all payouts were larger and still as frequent, having the anticipatory factor that watching the last symbol land to complete a winning combination has. Now, although these frequent payouts aren’t always as high as players hope, they are still enough to keep us playing!

Summarizing What to Remember

  • House edge is a predetermined aspect of all slots and will affect how a slot plays, and therefore its entertainment value
  • Slot machines have changed rapidly over the years and at the same time so has the number of possible outcomes
  • Slots are built upon the foundation of a simple random number generator, meaning all spins are unique
  • While the result of a slot machine spin is random, they are at the same time pre-determined by developers to follow a law of averages so to speak
  • Players today love the innovative video slots, but they also really love representations of classic three-reel slots and spinning wheels

Is It Possible to Beat Slot Machines

Although software developers are surging forward with new developments and changes for the world of slot machine games, when the dust settles – the slots are still purely a game of chance.

Being a chance-based game (which is not an uncommon notion) makes it difficult to pinpoint a strategy that allows a player to beat the house consistently. While slots will continue to change as they look to maintain player interest and excitement, we will begin to see more innovation as developers look to start increasing the amount of skill that can be applied by players.

Which sounds like it would be a win-win situation, right?

Well, that may not be the case – as you will see in the topics we cover in this chapter, things are not always as they seem.

What Happened to Banked Bonuses

In the 1990s, casinos were booming, and as part of this meteoric rise in participation came a feature that many thought would be here to stay.

But it didn’t.

This newly introduced feature was called ‘banked bonuses’ and allowed players to collect or bank a range of symbols during their play. These symbols would be collected up to a predetermined point when the awarded bonus action is activated.

What a smart player would do is wander around the casino floors, checking the bonus banks of slot machines hoping to find one that was close to its activation point (or triggering the bonus). Once this lucky machine is located, the player would jump on and start spinning.

This would allow players to finally have the edge over the casino because they had a much smaller window to play through until cracking the bonus.

As you would expect, casinos were not too fond of this after a while, and as a result, it is rare to find one of these slot machines still in rotation today.

Does It Pay to Chase Jackpots

One of the popular tricks to winning on slot machines is to live a life of jackpot hunting, which is a relatively straightforward idea which some players swear they’ve had substantial success with.

The basic understanding of being a jackpot hunter or chasing these jackpots is that while it is impossible to predict the outcomes of spins, many players believe that they can look at the value of jackpots compared to others and find a machine that is on the edge of triggering a jackpot win.

So, this is looking for a game that has a considerably higher jackpot value than the same game at other machines or casinos.

Following a system like this would involve quite a bit of pre-play research of games, so most players may not find it worth the effort.

What players do when jackpot hunting is walking the floors and recording data for themselves of prior payouts and the average jackpot payout. With this information, a player would then have an idea of what the average jackpot payout was and can look to play on slot machines that are sitting at that value.

If this were to work, it would be advantageous to players because it would lower the cash or bankroll needed to score a big win.

Now, there is no real guarantee that this type of jackpot hunting system works. In contrast, it would theoretically work with an understanding of averages, and we just don’t see this as being a particular strategy that would be effective enough to focus your time and effort into.

What are Skill-Based Bonuses

The implementation of skill-based bonuses in slot machines threw a big spanner in the works. What these bonuses did was provide players with an opportunity to use their skills to win a bonus event.

Players liked these features because it meant that they could enjoy playing bonuses that they felt that they had more power over and did not have to rely on random outcomes of spins.

The downside to this was that more often than not a player’s skill level was not good enough to get the full value out of the bonus, and therefore even if a player was to completely boss the bonus, most times this would not also cover the house edge in its entirety.

A prime example of these skill-based bonuses is the game Centipede (yes, just like the old Atari classic) by the iGaming software developer IGT (International Game Technology). The bonus for this game involved players playing a game of centipede. On average, it is expected that the maximum edge that skill has in these slot games is give-or-take 4%, which is generally still much lower than the house edge.

So, even if you were an absolute pro at the centipede bonus, the skill you bring to the game will not outweigh the house edge.

We feel that, for the most part, players who prefer to stick to these skill-based bonus games are doing so out of their interest in feeling that they have control rather than the actual winning chances being increased.

Summarizing What to Remember

  • Bonus banking games of the 1990s came and went like a flash, mostly because casinos certainly don’t like to payout money
  • Many players swear by jackpot hunting, but there is no hard evidence which supports this strategy, and most players would be bored by walking around casinos recording data
  • Skill-based games were a hit with some players, but they still don’t do enough to tip the ball into the player’s court

Playing Progressive Jackpots for Once in a Lifetime Wins

Over the years, jackpots have continued to reach more towering heights than ever before, especially with the introduction of these massive progressive jackpots.

Many players purely focus their slots gaming onto these progressive jackpot slots in the hopes of hitting the lottery for the once in a lifetime payday. It is easy to see why players take this chance.

When you visit a casino or log in online, the most eye-attracting aspect is the massive bank of screens flashing an ever-increasing jackpot. This draws players in, which is why they include these values above every slot machine.

Initially, these jackpots were confined to each machine and typically the same amount, but nowadays, players are lucky enough to have the chance to experience progressive jackpots.

These progressive jackpots are like a rolling jackpot; with every spin or bet placed by a player, a small portion goes towards the jackpot. The slot continues like this until someone is lucky enough to trigger the jackpot.

This is what you would consider the holy grail of winning at slots. However, there is more than just the one progressive jackpot to choose from, and we will break each of these down for you shortly, but first, there is an essential component of playing these games.

Not all bets count.

The payout rates of these games are less frequent, but they are more significant when they do (this is what is referred to as a highly volatile slot). However, given that wins are few and far between and not all bets count – it is therefore imperative to be placing the bets that do count!

For this reason, exactly, it is essential to read the terms and conditions at the casino. This helps to find any secrets or fine print that might stop you from winning. Typically speaking, on progressive jackpot slot machines – your bets will have to be for the maximum bet amount to qualify. This is a general rule of thumb to live by.

The Standalone Progressive Jackpot

As the name suggests, a standalone progressive jackpot is precisely that. These slot machines are confined entirely to each machine or game; therefore, all of the bets placed on that machine will contribute a small portion towards the jackpot kitty.

If you play at brick and mortar casinos, it is common for there to be a number of these slots grouped up. This is to create the idea that the machines are all linked up; however, this is not often the case.

Playing a standalone progressive jackpot is still an excellent choice to make. Once the payout is triggered, the jackpot will return to the base value and begin to accumulate again.

What Kinds of Progressive Jackpots Are There?

There are more variants of progressive jackpots for players to trigger, both of which affect creating a much more massive jackpot. Outside of the standalone or solo progressives, there are two more variants.

Local Progressive Jackpots

In a basic sense, a local progressive is a group of machines or slot games that have their jackpot linked together.

When you see several of the same machines all sitting next to each other, this is either to help show players that all of the machines are linked together for a more significant payday or to pretend that this is the case (as we said earlier).

The biggest jackpot on these machines are contributed to by each of the linked machines at the casino, this allows for larger jackpots but also an added risk of someone else winning before you!

Networked Progressive Jackpots

Think of networked progressives like your home wifi network. The jackpot is your wireless router, and each of the devices or computers in your home are connected and contributing their part to the jackpot.

This is where you will see the significant jackpots, and we are talking millions and six-figure paydays.

With these networks of slot machines all linked together, the jackpot accumulates quickly – but with such a vast network contributing, it also means that someone else might win before you.

A network of slots could include thousands of games all linked together, they could be all over the world, or they could just be among that software provider or casino.

The Effect That Progressives Jackpots Have Had on Winning Slots

For players, these extreme jackpots have had a significant impact on the industry, both positively and negatively.

While many players fixate on these jackpots because of their millions, they have created a false sense of hope for many players because all they see is the big payday at the end of the tunnel.

Unfortunately, your chance of winning the big one is about as good a chance as you have at winning the state lottery. But, players just cannot get away from the temptation of changing their lives.

In terms of winning at slots, just because you play on a progressive jackpot slot, it doesn’t mean that you have a better chance of winning. You could make a pretty strong argument that this would be quite the opposite.

Progressives are volatile slots, meaning that they pay out less often, but when they do payout, the wins are more massive. In theory, it sounds great, but in fact, the lower volatile slots are better for players bankroll and for winning at slots.

Low volatile slots feature frequent, yet much smaller wins. These slots can be thought of as chipping away at smaller yet more comfortable to manage wins. Whereas the progressives, involve a very long and very costly grind to break through any ground.

Summarizing What to Remember

  • Progressive jackpots allow players to win big paydays, except it is important to remember that not all bets are eligible to trigger the jackpot
  • Progressive jackpots can come in many forms, including standalone (by themselves), locally linked to other machines of the same game in-house, and networked amongst many casinos and many of the same game
  • These jackpot slots may not always be the best game to play because high volatility slots can be rougher on the player. Low volatile slots are more frequent wins at smaller amounts and are better for overall bankroll management

How to Pick the Best Slot Machines to Increase Your Chance to Win

Can you find that one slot machine that will guarantee you a win? While we are hoping to help improve your chances of winning, it is vital to stay realistic and understand the parameters of these chance-based games.

Obviously can’t guarantee wins, but we can help you to find strategies and tricks at winning slots. Which when used together with a little bit of luck, it will help you to choose the best slot games and use the best strategies.

Focusing on Return to Player Percentages

Return to player percentages are the estimated amount of bets over some time that the casino would expect to win.

These percentages are an indication of the returns for the casino but are not a guarantee of what players will win.

Players can find these percentages within the slot machine you are looking at playing.

While we recommend that players do investigate the return to player percentages, take it with a grain of salt and don’t merely live by them. When looking, aim for a game that is around 96%.

What is Slot Volatility and Why You Need to Pay Attention

One of the essential factors to consider when selecting your preferred slot machine game is the risk level associated with playing it. This can also be known as variance, or more commonly in gambling circles, as the slot volatility.

Some players consider that the volatility is what determines a player’s likelihood of coming out on top with a win on the slots.

Slot volatility comes in two forms, high and low.

With low volatility comes the chance of frequent wins but at much smaller amounts. When compared to high volatility slots, the chance of winning is much lower, but the payouts are much higher. These highly volatile slots can be more lucrative for players. However, they are much riskier and can have you drill through your bankroll like no tomorrow.

We recommend choosing a slot game that suits your playstyle preferences. If you are not a patient player, then the highly volatile slots are likely not the right choice. Therefore, for many of us players, the lower volatility slots are a much better option.

Make sure to remember this, though, and It is more difficult to find the actual variance or volatility of individual slot machine games than seeking information on RTP percentages. While more casinos are beginning to show this information on their lobby, you will need to do some pre-plan researching to find.

Being realistic, although you may not find actual figures, a look at the payout figures will give you a fair indication of the actual volatility of that game. An alternative method is to make use of the free spin options or practice mode available to players, and have a few spins before making your assessment of the results before risking your bankroll.

Research and Understand Games Before Playing

One of the most important factors to remember before you start to play is – do not get drawn in like a moth to a flame because of the sights and sounds attracting you to a particular slot machine.

Always ensure that you carry out some due diligence, particularly when deciding on which online casino or local casino to play with. Make sure that sites are legitimate and feature reputable gaming licenses in place with regulators such as the Malta Gaming Authority or the United Kingdom Gambling Commission.

Don’t forget to research the particular slot machine game too – don’t just load up and start placing bets without knowing what to look out for to win.

Maximizing the Value of Slot Machine Wins

The best way to increase your wins is to maximize the value of your wins, which can be done quickly by betting the maximum amount on each bet or spin.

Remember that small bets will rarely qualify for the mega jackpots on offer, and the potential winnings that you may receive are directly related to the amounts that you are willing to bet on each spin.

Maximizing the value of your potential winnings finally comes down to the level of risk you are willing to accept. If you are happy playing with small bets per spin and receiving smaller, frequent wins, then stick to a strategy that involves low volatile slots.

Whereas if you are happy to set aside a larger bankroll and accept that you might lose it all before that mega winning pay line arrives, the choice is yours.

It’s Important to Learn From Other Players

Whatever game you play, whether it be a table game or the slots, there will just always be other players around you with comments or reactions to the game.

When playing slots in the casino, a non-paying machine will soon be noticed, and other players will seek to avoid that game. Another way of utilizing information from other players is to check out the online forums, blogs, etc. Everyone loves to discuss their views on particular games and machines, and the communities are generally pretty rad too.

Specialty and Themed Slots: Good or Bad?

There is a problem with the latest specialty and theme-based slot machines. This is that software developers are basing more of their games on popular TV shows, movies, characters, and brands.

These fancy themes draw players to them even though they may not have the best RTP results. Many of the licensed slots that are being released pay more to license holders of intellectual property because of the well-known or marketable aspects of particular brands.

In turn, this will likely lead to a higher house edge to recover these higher fees.

Should You Claim Free Spins Bonuses

We share plenty of the best free spins and casino bonuses. One of the most underrated aspects of these bonuses is not that you can get free cash-value but that having free spins allows you to test out a game and familiarize yourself first.

You should always claim your free spins because even though many of these bonuses will have a maximum cashout limit (typically they are between five to ten times the number of spins), all it takes is one bit of luck to get a big win. You could have scored that maximum cashout amount from nothing.

Summarizing What to Remember

  • Return to player percentages are an essential component of understanding the actual value behind a slot
  • When it comes to choosing a game that suits how you like to play, it is important to look at the rate of volatility for slot games
  • Always research and look into a game before choosing to play if you want to make the best decision for your bankroll and improve your chances of winning
  • Don’t cut your wins short, always place maximum bets so that when you do win, you aren’t leaving money on the reel!
  • Consider the higher fees or costs that may have been associated with licensed or big brand name slot games; the house edge will likely be higher on these games
  • Always look into claiming free spins and use them to boost your chances of winning with free attempts at the big one, as well as for learning to play a new game before risking your cash
