The Mechanics of a Fruit Machine – the Classic Version

We’ve already talked in length about fruit machines in our article about the history of slot symbols, where we explained how they came to be. They are classic slots, but the early models didn’t give out coin payments and bore the distinct fruity symbols on their reels. The classic free offline slots had 3 spinning reels, a coin slot where you could insert your wager, and a lever that started the game. Later on, when winning money on those was legalised, other components were added – mainly a hopper, which held the coins available for payouts.

To play slots offline was pretty straightforward. Of course, the regulations were still lax, so proprietors didn’t have to publish the odds of winning – but slot fans tried to track them anyways by dissecting old models and studying the number of symbols on the reels. Combined with the payouts for different combinations – the only publicised information – this allowed them to track the payback percentage of the different models of offline slots machines. However, those days are long gone now – modern-day fruit machines are a much different beast.

Most Popular Offline Slots in the World

The beauty of the online fruit machines is just how different and diverse they can be. The slots offline are no different and this has led to some of them enjoying a broader appeal compared to the rest. No surprises here, as it is completely normal for some games to be favourited more compare to others. Check out the following list, where we have listed the most popular offline slots based on punters’ preferences.

Worthy Online Slot Alternatives

While you may be considering the offline slots to be your jam, do not disregard the world of digital reel machines. There are thousands of digital games for you to choose from, which are nicely dispersed across dozens of types and genres. It’s impossible for you not to find something to your liking, especially when we talk about UK free slots. So before we proceed with the topic at hand, have a glimpse at some worthy online slot machines that you can take a swing at from the comfort of your home.

How Do Free Offline Slots Work Today – A Look into the RNG

The inventor of slot machines would hardly recognise the modern-day free offline slots you can play in casinos and pubs. The classic mechanical models have gotten quite hard to find, while increased government regulation and the public’s thirst for better visuals and bigger prizes slowly made fruit machines more and more complex. Virtual screens have long replaced the traditional reels, and the outcome of each spin is determined by RNG engines.

This fact still surprises many players, because it means that free offline slots games are much closer to their online counterparts than you would think. The sophisticated machinery inside is now used mainly to power up the visual effects, while most machines handle even the payments online. Real coin slots are quite scarce, so if you want to see a genuine river of coins falling down, you might have to search for a while.

Reel Stops – the True Meaning of RNG

Much like online reel machines, offline slots are controlled by the Random Number Generator – the infamous RNG. The RNG module actually replaced the old mechanical reels. Modern slots do have virtual reels with a set number of symbols, but the true odds of landing a certain combination do not depend on the actual number of symbols.

Instead, the RNG modules are programmed with a specific number of ‘reel stops’. For instance, a reel could have a total of 25 symbols, but 100 possible reel stops, each of them corresponding to one of the symbols. You can see a simplified example in the figure below, which shows how modern programming can make two identical slots to behave differently. Keep in mind that the exact same principle can be applied to online slots.

In the example above, we study the first reels of two land-based slots, whit the symbols ordered from highest-paying to lowest paying one. As you can see, both have an identical composition in terms of symbols, with the single Bell symbol being the highest-paying one. If this were a classic slot, you would have a 1 in 10 chance of landing the bell symbols. However, with reel stops things get more complex – when you press the spin button, the RNG module determines which symbol you will hit by issuing a random number.

If you look at the total of the numbers, you can see that in Slot A, you have a 1/44 chance to hit the Bell, since it has a single corresponding number from 44. In contrast, in Slot B there is a 1/20 chance – the RNG module issues 2 numbers for the Bell symbol out of a total of 40. Furthermore, in Slot A there is a 6/11 chance to land one of the lowest-paying lemon symbols, while in Slot B this chance is only 1 to 2.

Reel stops allow the slot producers to fine-tune the odds of landing specific combinations. Don’t get the wrong idea – this is not cheating, since most modern slot games (at least the online versions) publish their slots RTP rates – this is another name for payback percentages. Neither the casino nor the game-producers can fiddle with the RNG after the probability for hitting different combinations has been programmed, and the RTP has been formalised. In fact, the larger number of reel stops allows slots to have higher maximum prizes. The lowest the odds of landing a certain combination, the higher payout that can be attached to it.

Some Common Slot Superstitions – That (Usually) Don’t Work

You can’t consider yourself a true offline slots casino player without having a chat about ‘sure-fire’ ways to win from time to time. Slot strategies have always been a part of the banter, though you should be warned that most of them go into myth territory. Here are a few of the main beliefs of punters that play slots offline – and the sad truth about them.

Hot and Cold Slots – many casino players believe that the behaviour of fruit machines can be predicted to a degree. Hot slots are the ones that are in a good streak, offering frequent wins, while the cold ones have gone stale and refuse to give payouts. Theoretically, hot offline slots should turn cold at some moment, and vice versa, so players often go seeking machines on a hot streak, or cold ones that should go hot soon. However, even if there has been some merit to this tactic once, it is quite useless nowadays as proven in our slot strategy article.
Reel Stop to Win the Day – There are some slot machines that offer you the chance to use a reel stop button. This is quite different from the RNG function we discussed earlier. Reel stops interrupt the spin, and people believe that this gives you a chance to target winning combinations. Quite simply, this isn’t true. With modern slot machines, everything is governed by the RNG. What you see on the screen has nothing to do with your final result – which means that reel stops are simply making your spins faster, unless it’s explicitly stated otherwise.
The Casino Can Influence the Outcome – being suspicious towards the casino is perfectly natural. It does hold an advantage over us – a well-known fact that allows the casinos to maintain their lavish decors. However, some gamblers take it too far by accusing casino staff that they are changing the behaviour of their slot during a playthrough. To put things bluntly, this isn’t possible – slots offline are subject to strict inspections by the licensing authorities in every region where gambling is regulated. Most slot machines are sealed, and if a random inspection doesn’t find the seal intact, there are severe sanctions for the offending casino.

You Can Actually Play Offline Slots Games Online – Here’s How

Online fruit machines might be all the rage in today’s day and age, but they aren’t all that different from the free offline slot games you can play in Las Vegas. When the first digital reel machines appeared back in 1994 (read more about slot history here), they marked the beginning of a booming industry. However, there are many software studios that specialise in remastering already existing offline slots and offering you the chance to play them from your PC or mobile.

The leading brand here is IGT, one of the most recognisable slot manufacturers internationally. The company introduced the first video slots in casinos across the world during the 80s and quickly became a global leader in terms of production. Many of the most popular Las Vegas slots are IGT productions, and the company was quick to grasp the opportunity and transfer its products to the online scene.

IGT slots can be somewhat lacking if you compare them to online slots from leading software developers such as NetEnt. Due to the company’s unique position as a strong offline slot manufacturer, though, the products of IGT are the best means for fans of online gambling to feel as if they are touring the bustling halls of Las Vegas and other famous resorts.

Slots Are Now the Most Popular Casino Game Worldwide

Most gambling fans are well aware that, for good or bad, slots are the undisputed winner of any casino game popularity contest. However, you might be surprised to hear that this wasn’t always so. The ability to play slots offline started to appear towards the end of the 19th century and even though they gathered a dedicated following rather quickly, they were considered sub-par to poker, roulette and blackjack until the 1980s. Back then, technological advancements allowed for the first video slots to appear, and they quickly stole the show with their superior graphics and bigger win potential. According to the statistics of the United Kingdom Gambling Commission, slots are by far the dominant gaming machines in the gambling industry, and their numbers continue to grow steadily.

Online vs Offline Slots – The Main Dilemma

There is little competition between online reel machines and slots offline. The two types of games are actually extremely similar, considering that they work quite the same. However, playing an offline and online game feels totally different. While digital games are much more accessible for the average player, real fruit machines will remain in use and prosper. Much like online casinos will never take the place of brick-and-mortar ones, online slots and fruit machines also aren’t in direct competition.

Land-Based Slot Machines vs. Online Slot Games

Land-Based	Online
Harder to Find the Payback Percentage	RTP Is Usually Listed
A Social Atmosphere	Can Be Played in Solitarity
Spectacular Designs	More Visual Effects
Can be Hard to Find	Can Be Played Long-Distance

In the end, whether you prefer digital ot free offline slots is entirely a question of personal taste. Many people enjoy the bustling casino environment and the more chances for interaction, but others prefer to spin the reels from the comfort of their homes and consider gambling as an indoors activity. If you meet someone who claims that offline slots machines are superior to online ones – or vice-versa – then he is definitely pulling your leg. There are good and bad offline slots, just as there are good and bad online titles.
