Online casino gaming allows players to take on a variety of casino games such as blackjack, poker, and roulette at home or on-the-go in a number of states including Michigan, New Jersey, Pennsylvania, and West Virginia.
But the most plentiful type of online casino game is the online slot, as US players can enjoy hundreds of high-quality real money slot games from the comfort and convenience of their Apple or Android device. Here, we look at the best US online slot apps and sites and break down what sets different online slot casinos apart.
How We Pick the Best Online Slots Apps & Sites
When we pick the best real money slot apps and sites, there are many criteria that we evaluate to make such decisions. Every online casino offers online slot machines, which give players the opportunity to win real money. But each app and site has their own unique characteristics that can be used to pick which one you should use when playing the slots that you love.
Continue reading for a look at the factors we use to decide which online slots apps and sites are the best. You can then look at these criteria on your own when checking out each online casino that you come across to determine if that app or site is worth your time.
Return to Player (RTP) & Volatility
When it comes to playing slots online, US players absolutely must make themselves familiar with the terms Return to Player (RTP) and volatility. RTP refers to the percentage of funds wagered on a slot game that a bettor will win back over a large sample size of spins. Volatility is a product of that RTP percentage, where lower RTP slots carry higher highs and lower lows (higher volatility) than slots with higher RTP percentages (lower volatility).
Ideally, an online slots app or site will have a good mix of high volatility and low volatility slot games. In doing so, an online casino will provide an ideal mix of games for players who have an interest in playing each of these types of games. On top of that, a wide range of RTP percentages will let players target games where they are able to balance their level of comfort with the volatility levels and the potential for big jackpot wins.
Game Design & Availability
Another factor that online US slots players will want to be aware of is the level of game design quality that is up for grabs at each online casino. This is often a product of the different game developers that online casino sites are partnered with, as different developers often produce games that look and feel very unique from one another. Of course, which looks and feels bettors like is very subjective, so the more options that a casino site has the better in most cases.
Gamblers will also want to look at the overall slot game variety at each app or site that they play at. While every online casino has many classic slots to choose from, some offer more than others. Apps and sites with superior variety have a better chance of appealing to the preferences of every player and can help players discover new slot favorites that they had not thought to try before.
Casino App Design
Another often overlooked component when determining which online slot providers are best are the app designs for each online casino. There is a lot that goes into deciding which casino apps are designed the best, but the two most important components are the design with regard to user experience, as well as the aesthetic appeal of the app.
The user experience of each casino is vital to each app’s candidacy as the best online casino app. It needs to be easy to navigate between sections of each casino app, and it needs to be easy to find the games that players want to get involved with. Some apps have a search function or alphabetize their game selection to facilitate that process.
The visuals of each app can also draw players to an online casino or turn them away from that casino site. Everything from the color scheme of an app to what the fonts look like can determine whether or not an online casino is visually appealing. While this certainly does not impact the gameplay at a casino app itself, it does make a good or bad first impression that can really shape the casino experience.
Advantages of Playing Slots at Online Casinos
Some potential online slots players may want to know what the benefits are to playing online slots at all. After all, there are plenty of land-based casinos in the United States that offer brighter lights and bigger screens to play these games on. But there are some undeniable benefits to playing at the online slots apps and sites that we have recommended later on this page, and those key benefits can be found below.
The number one thing that makes online slots apps and sites worth using is the convenience that they come with compared to land-based casinos. To play at a land-based casino, bettors have to go to a physical location, paying for their transportation. That means that if bettors do win at the slots at that casino, some of their winnings are instantly eaten up by simply having to pay for gas or mass transit to get to that facility.
Bettors also have just one available payment method that they can use when they go to a land-base casino. That payment method, of course, is cash. Bettors have to physically give cash to a dealer at table games, or physically put cash into a slot machine to start playing. That means bettors have to already carry cash into a casino, or they have to use an ATM at that casino and pay the ATM fees that come with that transaction.
Those issues simply do not exist when utilizing one of our recommended online slot apps or sites. Bettors can play from wherever they are as long as they are located in a state, eliminating the need to eat into any potential winnings with travel costs. Additionally, bettors can fund their online casino accounts in a number of ways, without needing to carry cash or pay ATM transaction fees.
Bettors should think of all the other ways that online casino gaming is more convenient than land-based casino gaming based on their specific circumstances. This will shed additional light on the benefits of utilizing the apps and sites we recommend on this page as opposed to going to a land-based provider in a place like Las Vegas or Atlantic City.
Easy-to-Find Game Information
Another massive benefit to playing online slots instead of playing slots at a brick-and-mortar casino is the fact that game information is easily accessible on your computer or mobile device. Without having to move, bettors can find the RTP percentage, betting limits and denominations for a massive amount of online slot titles. At a land-based facility, on the other hand, players have to physically sit down at each game they want to learn more about in order to read that information.
Of course, the real draw of online casino play is the ability to play all of those online slots without having to travel and walk around a massive room to play different games. But being able to research all of the different games that you are interested in without having to do all of that traveling and moving around makes picking games to play so much easier than it would be at a brick and mortar casino.
Play From Anywhere In State
As we mentioned earlier, using an online casino means the ability to play online slots without having to go to a physical location. But the flexibility that online casino apps have granted players deserves a little more attention. At online casino apps or sites, players can take on their favorite games from anywhere in each state where that online casino is legal. That means players can take on slots from the border of those states, the middle of those states, and anywhere in-between.
Online casinos verify a player’s location using a couple of different pieces of technology. On desktop devices, locations are verified using a location verification software that players are required to download so that casinos can ensure that they are only taking bets from players located in legal states. On mobile devices, bettors will simply have their location verified using the existing location services on their device.
The biggest advantage to online casino play to many online casino players is the presence of online casino bonus codes. When you go to a land-based casino for the first time, it is highly unlikely that you will walk through the door and be handed extra money to place bets with. But for those looking to enjoy online slots, real money free spins or bonus offers for new players are often up for grabs for those who sign up with a gambling site or app.
There are several major bonus types that have the potential to appeal to different online slots players. The most common type of bonus is the deposit bonus, where bettors receive a bonus that comes as a percentage of a player’s first deposit amount. Those bonus funds can then be used to play slots using the house’s money before using the amount that the player had initially deposited.
Another popular online slots bonus is the no deposit bonus, where online casinos give players a small amount of bonus funds without a first deposit being made. This type of offer lets bettors try a site before they have to deposit funds, which represents a nice value for those new customers.
There are several other online slots bonus types, such as free spins bonuses and loss rebate bonuses. No matter which type of online casino bonus a player utilizes, it is more beneficial than not having access to a bonus at all from a land-based casino.
Popular Online Slot Types
When trying out the best online slots apps and sites listed below, players will see a wide variety of popular games up for grabs. Among those the most popular slots will be games that fall into each of the slot game categories listed below.
From old-school games to more modern titles that have a ton of moving parts, players should get to know each of the different game types out there so that they have an idea of how each game works before they start wagering their money on each of them.
Three-Reel Slot Games
Online slots that have three reels are reminiscent of the old-school slot machines at brick-and-mortar casinos. These games have three reels that spin vertically, which often have anywhere from one to five paylines on which players can hope to form winning combinations. Three-reel slot games tend to be more basic than titles that have more reels, but some of these games do feature bonus rounds and other bells and whistles that come with today’s modern slot titles.
The one huge benefit about three-reel slot titles is the fact that it is often easier to keep track of where a player is putting together winning groups of symbols. Fewer paylines means fewer places to look for wins, which is great for newer slot players or experienced players who want a more straightforward gaming experience.
Five-Reel Slot Games
Some of the best online casino slots are more modern five-reel slots, which feature five vertically spinning reels as opposed to the aforementioned three reels. The big appeal of these games is the fact that there are more reels, which means more opportunities for the reels to show symbols that can combine to form wins. These games also often feature more paylines, thanks to there being more combinations along more reels.
Five-reel games also often feature the potential to play for higher stakes, as bettors can wager on more paylines at the same time. This gives players the chance to win bigger if the symbols on each reel turn out the way they need to.
It should be noted that those playing five-reel slots should be sure to read the rules of the game they are playing before they perform too many spins. With more payline combinations available, bettors should educate themselves on which portions of the screen can be used to form winning combinations to avoid any surprises when a game does or does not pay out on each spin.
One of the most alluring components to online slots comes in games that offer jackpots to players. Some games offer traditional jackpots, which are a fixed amount for those lucky enough to win them. Others are progressive jackpot slots, which are jackpots that grow as bettors continue to wager into them. Either way, the potential for a jackpot payout is certainly capable of elevating any slot title in the eyes of its players.
When looking at jackpot slots, players will want to check the RTP percentages and volatility ratings very closely. The jackpot payouts are baked into the RTP percentages, meaning that non-jackpot winners could win less in these games to make up for the eventual jackpot payout. This is not meant to discourage players from taking on those titles, it is just something for players to be aware of.
Slots With Bonus Rounds
Whether or not a slot title has a jackpot attached to it, the presence of a bonus round or multiple bonus rounds can make a slot game more exciting for players. Bonus rounds are where game designers can get creative with their titles, as they are not confined to the traditional reel structure of typical online slot play. While some bonus rounds remain on the reels in the form of free spins, others can take players to space, the bottom the ocean, or anywhere in between with heavily animated features.
Along with the potential for visually appealing bonus rounds, the most important thing about bonus rounds at online slot games is the potential to earn big payouts. Many online slot bonus rounds offer payouts that are much larger than what are typically awarded during normal slot play. Those big wins can be the most memorable portions of any online slot session, in addition to being the most lucrative.
Best Online Slots Apps & Sites
