While slot machines have existed in brick and mortar casinos for decades, online slots are a new and evolving creation. The first iteration of real money online slots came to fruition when the first online casinos were created in the late 1990s. It was in the mid-2000s. However, online casinos began to take off both in popularity and ingenuity. Many slots that you can find in your local casinos can now be played online, both for free and, in some cases, for real money.

Several companies exclusively produce online slots. Many of these games are primarily found at offshore online casinos, as opposed to casinos in regulated territories like the UK, or even New Jersey and Pennsylvania online casinos. Some of the most well-known online slot producers include Endorphina, GameArt, and WGS, but they are hardly the only online slot companies.

How Real Money Online Slots Work

For the most part, online slots work the same way as the majority of slot machines that you will find in casinos around the world. Unless otherwise noted, online slots typically use an RNG to generate results for each spin. This means that each spin is as close to truly random as possible. Unlike a deck of cards in an actual, physical casino, the exact time that you hit the spin button will play a role in determining what the result is. If a deck of playing cards is set, the cards will not change based on your decisions. With slots, though unpredictable, your actions do impact the result.

In terms of win frequency or games offered by betting limits, online casinos tend to offer lower limits than most B&M casinos. This is for a few reasons. First, online slots allow for a much faster pace of play. If the online games are 2x faster, you will effectively be risking the same amount if you play for 50c per spin online, as you would be risking $1 per spin in your local casino. The casinos know this, and lower limits help to encourage more play. While some online casinos offer high limit slot play, the majority do not offer many games over $20 or $30 per spin.

Licensed vs. Unlicensed Online Slots

Have you ever noticed how many slot machines in casinos closely resemble the Wheel of Fortune game? This isn’t a coincidence. Game manufacturers saw that the WOF formula was a significant hit among players, and the bonus spin format has been repeated in many different ways. Online casinos, too, know what games players do and don’t want to play. As a result, you will often find games that may look and even sound like your favorite slots, but may, in reality, be close imitations.

The lack of regulations for casinos that operate offshore allows them to operate in a total grey area where they are virtually immune to legal action of any sort. Online casinos that offer “rip off” versions of IGT or Aristocrat slots, for example, do so because they know that they won’t get in trouble. While it is your prerogative to decide whether or not to endorse these games, our recommendation is to check and make sure exactly what game you are playing, especially if you are depositing and risking real money.

Fairness of Online Slots

Perhaps the biggest downside to playing online slots, especially at unregulated websites, is that it can be challenging to prove the fairness of any games that are offered. While Bitcoin casinos can prove that they are provably fair, classic online slots are not as well-vetted. While many of these online casinos do have “licenses” from different gaming bodies, they are usually not from an organization that researches whether the games are genuinely fair. We advise that you tread lightly whenever you are playing online slots for real money.

In casinos, like those in Las Vegas, the gaming commission will perform audits on the machines on the floor. There are various thresholds, depending on the area and commission, that casinos need to abide by. For example, a Las Vegas casino may not be able to hold (have an advantage of) over 10% of the total risk by the player. The higher stakes, generally speaking, the less house edge that exists in casino slots. With online slots, however, fairness is mostly a guessing game. The best thing that you can do is to research the casino itself. If you are playing at a state-licensed casino like those in New Jersey, you have nothing to worry about. If you are playing at an unregulated online casino, however, you should complete a bit of independent research to ensure that they do not have a poor reputation.

Payouts

Another risk to online slots is that of payment. This again comes back to researching before you play for money at a casino. Nothing would be worse than hitting an online progressive slot jackpot and then not being paid by the casino. While many, even most, casinos will be fair and pay you any earnings (so long as you didn’t break any rules), there is always the risk of a rogue operator who will hold your funds.

Progressives, like the percentage hold, are also not monitored, so they add even more risk to the player. For instance, the online casino could be holding half of the money they *claim* is being added to the progressive jackpot. In general, there isn’t any valid way to check that online casino progressives are being operated with total integrity. You should be aware of this potential casino, but keep in mind that joining a reputable online property is the most important step you can take.

Below are a few links to articles we have written about a variety of slot topics. On each page, we try to cover everything from how to play them to general information and even include real-play videos that we have filmed at live casinos. Read on to learn more about slots, and the different varieties offered at casinos.

Types of Slot Machines

There are many different types of slot machines. A lot of new casino visitors may be overwhelmed by the sheer selection of available games, whether you visit a small locals casino or a large resort in Vegas. There are video slot machines, 3 reel slots, 5 reel slots, and so on. These three categories will cover the bulk of machines that you will find in most casinos so that we will focus mainly on those.

Video Slot Machines

Our articles within the video slot machines section offer a dynamic and in-depth look into many different available games. The easiest way to identify a video slot machine is by identifying the games that look nearest to a video game on a computer screen. When it comes down to it, that’s what these games are. Though they are on electronic screens, many of the games function similar to reel slots in that they are usually offered in 3 and 5 line varieties.

One of the most attractive elements of video slot machines is typically found in the bonus rounds and games that they include. Where conventional slot machines usually trigger a bonus round and then simply offer a fixed amount of “bonus” or “free” games, a video machine will usually incorporate some level of graphics and possibly other features. This is why so many players are most interested in video slot machines because they are much more dynamic and interactive. For many, they are simply more fun and enjoyable experience, and in the end, that is what it’s all about.

3 Reel and 5 Reel Slot Machines

If you walked into a casino in the 1970s, you would have likely encountered 3 and 5 reel machines almost exclusively. These are the sort of machines that are generally printed in advertisements and seen on TV and movies. Reel slot machines are named for the fact that each of the lines (3, 5) is on a reel. A reel slot machine is best identified by the arm that is found on the side of most of the machines. In this day and age, though, many reel machines no longer offer patrons the ability to pull the reel, and it is only there for show.

Reel slots date back to the days where slots paid out in actual money (change). Today, however, these machines almost always function using vouchers. Cash or an existing voucher is inserted to generate playable credits, and a voucher is printed when play is completed. Reel slots are frequently best recognized for their “hit or miss” nature. Where some video slots may offer smaller potential wins in exchange for less dramatic losses, many reel slot machines exist under the premise of potential big wins, but frequent moderate to large losing streaks. As a result, if you are interested and intrigued by the idea of possible variance, reel slots will be appealing.

Slot Machine Payouts

The payouts or RTP (return-to-player) is one of the most important and widely discussed aspects of slot machines. Where to find loose slots and which slots to avoid. Unfortunately, when it comes to brick and mortar casinos, there is no answer to that. The range is high, and you just can’t know for sure which machine will give you the best odds.

The good news is that in online casinos, the situation is very different, and there are plenty of software providers that are forced to post the expected lifetime return of every game. That’s, in fact, one of the biggest advantages of playing slots online vs. land-based casinos. You know exactly which slots to pick and which to avoid. Here you can find an up-to-date list of best USA slots online by payout, which will grant you the highest chances of “going home” with some extra cash.

Playing Slots

There is little tutorial or instruction needed for anyone interested in playing a slot machine. Many experienced players will offer words of wisdom like, “always play the max bet,” but the truth is that, for the most part, your risk and reward tend to be proportionate. As is the case with every casino game, the most important factor in how and what slot machines you should be playing is found in the size and variance tolerance level of your bankroll. If you have a lot of money and are going for the shot at a huge win, you are going to play at a different pace and potentially at different machines than someone with less money who is trying to make their funds last longer.

Cons to Playing Slots

One of the downfalls of slot machines is that they can suck you into their action. Some table games, like Roulette, tend to move along at a slower pace, which either bores or tires players before they run out of money or keep putting more chips on the table. With slots, however, the quick and fast-paced action can easily encourage a player to keep chasing after more and more action. Since the massive wins are so far and few between, ending up with a losing individual slots session should not come as a surprise.

When it comes down to it, even a casino enthusiast who does not typically play slot machines will usually be willing to admit that they absolutely can provide a large dose of excitement. The ups and downs of table games may be thrilling, but few games in the casino offer the prospect of a massive win in the blink of an eye like a slot machine does.

Bonus Rounds

One of the biggest draws to playing slot machines for many casino enthusiasts are bonus rounds. These are only offered on some machines and include everything from free spins in the game itself, to special bonus spins (such as those found at Wheel of Fortune) and other unique types of mini-games built into a machine. One of the most popular bonus rounds in all of slots can be found on the Wheel of Fortune Machine. It is far and away from the most played slot machine, and consequently, it can be found at virtually every casino in America.

Progressive Slot Machines

Progressive slots are another big draw for casino enthusiasts. If you are unfamiliar with slot machines, picture a progressive as an office prize pool that slowly grows over time. Progressives are offered only on certain machines, and their value slowly builds up over time, determined by people putting coins into other machines at various casinos. For example, in Wheel of Fortune, the progressive slowly grows and is paid out only when a player hits 3 “Wheel of Fortune” symbols. Not an easy task by any means, with lower odds. It is different from a jackpot in that it is not a fixed amount of money, but rather it slowly builds up over time as others play the machine. This continues until the progressive is hit and then resets.
