How Does Slots Work?

Today there are thousands of different slots to choose between when you’re playing online and all have their own themes, graphic styles and functions but in the end, they all work in the same way. Most slots today has three of five wheels with different types of symbols on them, these symbols are customized according to the theme of the game to give an extra layer of excitement and fun to it. The goal of slots is to get winning combinations of the symbols which pays according to a pay table, the better the symbol the bigger the winnings.

Slot machines today also offers bonus rounds and additional features that can be won inside the game or randomly triggered while playing so that you can never foresee what’s going to happen next. This is called RNG which stands for Random Number Generator and it’s something that every serious online casino uses.

Another good thing to keep track of is the volatility in slots, this is how much and how often a slot pays out. High volatility means that the payouts will be big but won’t happen as often while Low volatility is lower risk but the payouts will be smaller. This is the basics of slot machines and how they work.

Bonus Features in Slots

When it comes to the bonus rounds it’s something that has gotten more and more popular lately since it adds more excitement to playing slots. Bonus rounds can consist of extra big winnings, free spin rounds where you get to play for free and get additional effects for the chance of really big wins.

The three most common things you’ll find in bonuses are Wilds, Scatters and Multipliers but there are tons of different bonus features today, some of the most popular ones are the following:

Wilds: These symbols are used to help you build paying lines and will replace all other symbols except for the bonus symbols. A good example we can use is that if you have a star or a diamond on wheel 1 and 2 but none on 3, if you then have a Wild on wheel 3 it’ll still count as a line win because the Wild symbol counts as a star or a diamond. Imagine the Wild symbol as the joker in a card deck which can replace other cards to get a winning hand. Apart from the normal Wild symbol that only takes up one symbol slot you can also get Expanding Wilds which covers the entire reel or Sticky Wilds which means that the Wild will stay in place for the duration of the bonus round.

Scatter Symbol: The scatter symbol is the feature used to trigger the Free Rounds or Bonus in a slot, you usually need a combination of 3 or 5 of these anywhere on the board. You’ll usually get more Free Spins or a better bonus the more Scatter symbols you hit, but every slot works in different ways so there are no set rules here.

Pick and Click Bonus: This is one of the most common bonus forms and it’s a bonus where your own choices decide the outcome of the bonus. Some people think that this is rigged and it doesn’t matter what your choices are but some providers have proven that it’s fair and your own picks do in fact matter. You’re given a bunch of options to click on and behind can hide bonus features, coin wins and there’s usually one or two of the options that end the bonus which you do not want to click. Some games like Blood Suckers 2 even sends you to the next level if you manage to find the right symbol which will then contain even better wins.

Multiplier: Multipliers is used in almost every  Casino Bonus and it’s something that will increase your winnings by a lot if you get high Multipliers. If you, for example, get 10 Free Spins with an x3 multiplier that means that all your winnings during these spins will be tripled compared to if it was a normal base game spin.

High Variance Slots

The market has been blooming with high variance slots lately. More and more players are looking for the big winnings of high multipliers, rather than playing lower variance slots that just cant pay these big amounts. It’s hard to tell the exact reason for this, but we definitely think the Youtube and Twitch community has some play in this. Players want to hit that incredible big win that they can share with their friends and community. It also obviously feels really good hitting something big, rather than just winning low amounts.

Providers such as Big Time Gaming, Push Gaming and Relax Gaming have been in an arms race lately in creating higher and more volatile slots. Bonanza was most likely the trigger of this, as it definitely revolutionized the slots market, and it was incredibly volatile for it’s time. Since then, even more volatile slots have entered the market with the potential of winning upwards of 50 000 times your stake. For reference, Bonanza could pay out around 15-20 000 times the stake. We’re getting up into the Jackpot level of payout territory now, and it’s gonna be interesting to follow the race. How volatile can a slot actually get?

High Max Win Slots

Players want slots that payout crazy amounts, but how volatile is too volatile? Who knows, but it’s definitely going to be interesting to follow. Just a couple of years ago, a win of 1000x or similar was something incredible. Today, that’s pretty much nothing when discussing high volatile slots. Some slots have the potential of paying out upwards of 50 000 times the stake, which is completely wild.

More and more providers are opting for High Max Win Slots. We even see providers such as Quickspin, who is previously known for their low volatile slots, releasing High volatile slots with incredible max wins. As for providers mainly known for their high volatile slots, it’s Big Time Gaming and Relax Gaming mainly. Players are constantly anticipating their new slots, and they always end up high on the Popular Slots tabs at online casinos.

The problem with these High Max Win Slots is that they have to be very High Variance in order to be able to pay out these amounts. This means that most players will never be able to win big on these slots. With such high variance, eventually it just feels impossible to hit anything. You can go double digit spins before you even see a win. Eventually players will most likely get bored, but who knows, it’s hard to tell as the volatility in slots has just been getting crazier every year.

Design

The design on slots is something that is very interesting. Back in the days, when slots were mainly just on land based casinos, bars, and pizzerias, they mainly just consisted of fruit symbols with 3 wheels, 3 rows and 9 paylines. Since then, they’ve evolved a ton. Today, they could be compared to video games with very high quality graphics and cool designs. Most providers have their own niche and design patterns that they usually go for. This is how you can easily tell providers from each other, and why you most likely have favorite providers.

The design aspect of slots is actually very fascinating. And following the evolution has been very cool. We can’t wait to see what slots will look like in the future. We will most likely get really cool designed ones with the new generation of VR headsets with Virtual casinos and Slots. We know that NetEnt already started designing their own slots for these types of casinos.

Something else that is also very refreshing is the fact that slots don’t even follow the same rules of wheels and rows set-up anymore as they used to. Look at the Megaways feature for example, with dynamic paylines that change for every spin. Slots such as Fruit Warp from Thunderkick don’t even have paylines, but instead just random fruits thrown at you. There’s tons of cool designs and the providers are constantly coming up with new and interesting design ideas.

RTP

RTP is a term that is thrown around when talking about slots a lot. But what does it actually mean? It’s quite simple. All slots are built to make the casino money in the long run, and the RTP guarantees that. RTP stands for Return to Player, and is a procent that tells you how much you’re expected to get back over millions, if not billions of spins on the slot.

Example: A slot has a RTP of 96.7%. This means that if you deposited 100 dollars, you’re expected to get back 96.7 dollars over a long period of time.

Something to keep in mind is that this number doesn’t affect you in the slightest short-term. RTP is only used long term, over millions and millions of spins. You can still win big from slots when playing and have an RTP way above the expected over a shorter time period. That’s what makes slots so fun, they’re unpredictable short term and have the potential of paying out big. Never use RTP to determine what slots to play.

What Makes a Slot Popular?

What makes a slot popular depends on what type of game provider it is, some people have their favourite game provider and only plays their games while many of us have our own favourite slots that we always come back to and feel comfortable with. Maybe it’s a certain type of bonus round that you strive for, a fun theme or the chance of spinning and winning the jackpot in games like Mega Fortune or Hall of Gods.

Other people care less about titles and look for the best free spin deals where you sometimes can get tons of Free Spins or Free Money when signing up. A fun theme that you’ll quickly see is very popular is themes based on movies, tv series or music bands. Here we find titles like Guns N’ Roses, Halloween, and Game of Thrones. These are classics that gets you really nostalgic when you play them and some people find that fun.

New Slots Released Every Day

Slot machines give you the chance of winning really nice amounts of money if you’re lucky and it’s also really exciting, that’s the most common reasons why it has exploded recently and gotten so popular. From the beginning it was very simple slots which you could only play in physical locations such as land-based casinos, pizza places and at the local bar but with the sudden spike in popularity the last few years it has gotten popular online as well and now there are thousands of online slots that can be played on online casinos.

The different slot providers are constantly fighting about who can make the best slots which have resulted in new slots almost every single day with new themes, exciting features and fun bonus rounds. You’ll notice that different game providers have different niches and different styles, some providers focus on high volatile slots while others focus on low volatile ones and some like to keep the classy old school theme while others focus on today’s amazing graphics. There’s really something for everything and that what makes it so great.
