Casino enthusiasts in Pennsylvania have been able to enjoy online slots legally since 2017 after the state passed a law allowing real money online gambling. Casino sites such as betMGM and BetRivers operating in PA state are heavily regulated by the Pennsylvania Gaming Control Board, which aims to protect players by ensuring operators comply with the law.

Please note that you’ll have to be at least 21 to register and play slots at a Pennsylvania online casino. The Pennsylvania Gaming Control Board requires players to verify their identity before getting started to prevent underage gambling. Players also must be physically located in the state to play at PA online casinos. 

Our goal is to ensure players have access to the best slot sites in the state. As such, we developed a thorough method that rates online casinos according to several parameters, including welcome bonuses, promotions, and the number of games.

Types of Online Slots In Pennsylvania

We could have been really nitpicky here and divided online slots in Pennsylvania into dozens of categories, but that means we would have to explain them all so we narrowed it down to three basic ones to make life easier for you, and us. We’re sure you’ll agree.

Classic Slots

These are the simplest slots to play as there aren’t many features to keep track of. Classic slots are ideal for traditional slot players clinging to the days when it was all about hitting three cherries in a row.

Apart from being simple to play, classic slots are very enjoyable. Graphics and sound effects are easy on the eyes and ears. The early versions of classic slots don’t pay out as much as their modern high-tech counterparts, but seeing as there’s a market still for this category of slots, there are new and innovative titles with all manners of finesse and jackpots even.

A couple of popular three-reel classics in PA are Triple Diamond by IGT and Sapphire Spin from Red Tiger.

New Slots

When we say new slots we’re not talking about the latest slots released, we’re talking about modern beasts with free spins, Megaways, infinity reels, cluster pay, avalanche, bonus buy, giant symbols, progressive jackpots going as high as seven figures, and more. Modern slots have come a long way and game developers are trying to one-up each other with new game mechanics and higher max wins all the time.

Take Starburst by NetEnt as a great example. It use to be quite innovative when it was first released in 2012 as it allowed for winning from both left to right and right to left (Win Both Ways). The slot has wilds, expanding wilds, and respins to help hit winning combinations.

The game is still one of the most played slots to this day. But it wasn’t enough for NetEnt. Starburst started to fall behind mainly because of its 500x max-win, so the game studio constructed an updated version. In 2021 they released Starburst XXXtreme with a max-win of 200,000x and you can find it at BetMGM.

Jackpot Slots

These are the most alluring games on PA online casinos. The jackpot will continue to increase after every wager made and will continue to do so until a lucky player wins. When that happens the base jackpot resets and starts growing again. 

Online casinos usually display the amount accumulated for the jackpot. These slots come with various themes and features. Players can win up to millions playing jackpot slots. A couple of  examples of jackpot slots in PA include Divine Fortune by NetEnt and Cleopatra by IGT. 

Top 3 Slots In Pennsylvania

We promised that we would get to the slots you don’t want to miss and here we are, the top 3 slots in Pennsylvania.

Divine Fortune Megaways

This slot from NetEnt offers plenty of excitement with a chance to win big. Unlike Jumanji from the same developer, Divine Fortune Megaways has key features like falling wilds, wild-on-wild, and free spins. 

Since it’s a Megaways slot you’ll have 11769 ways to win. Collect coins to get to the progressive jackpot minigame where the big bucks are waiting. Wilds during the base game will move one position down after every spin and if a wild lands on a wild it will expand to cover the entire reel. 

The music is very relaxing and it’s easy to drift away so keep a close eye on your bankroll. Other than that, enjoy this action-packed slot to the fullest.

Wheel of Fortune Megaways

Here’s a Megaways slot from IGT that offers 117,649 winning ways and an RTP of 96.46%. Each reel generates two to seven symbols, including the regular wild and scatter symbols. 

You can win up to 81,500x your stake on Wheel of Fortune Megaways compared to Gonzo’s Quest Megaways with 21,000x despite both slots having a relatively similar RTP. 

A purple symbol with a diamond ring pays out the most. It pays out 25x when you get six similar symbols on the reel. There’s a one million Megaways bonus where even the lowest paying symbol pays out a sizable amount. 

Gonzo’s Quest Megaways

Gonzo’s Quest Megaways is a highly volatile slot with a Mayan theme from Red Tiger Gaming that has an RTP of 96% and is one of the most played slots at PA casinos. It has the popular avalanche feature which removes symbols from winning combinations and replaces them with new ones for a chance to keep winning. 

Gonzo’s Quest Megaways pays out a maximum of 21,000x your stake with 117,649 winning ways. Montezuma Megaways is an alternative to Gonzo’s Quest for having a the same game mechanic, but its max win of 12,500x can’t match the winning opportunities available in Gonzo’s Quest Megaways.

How To Play Online Slots In Pennsylvania

When at your favorite PA casino, choose a slot you want to play and look for the operating buttons, including “spin,” “max bet.”, and your bankroll. Check the game’s paytable to understand the value of each symbol, which ones to look out for, and the payouts for combinations. 

You then choose the value of your bet and the number of paylines, if it’s an older slot, and click spin to get started. Spin the wheels manually or choose autoplay if you don’t want to exhaust your finger. Make sure you know all of the features of the game and this is especially the case when there are free spins and bonus games available. 

Top Online Slot Bonus Features

Slots have various payout-boosting features to extend your gameplay. Developers are constantly introducing new game mechanics and modes to make their slots more appealing. Before playing an online slot, here are some features you must look out for.

Wild Symbols 

These substitute other symbols in a game to give you a chance to create a winning combination. Some slots have wilds with various features, including sticky wilds, walking wilds, expanding wilds, and cascading wilds.

Free Spins

These are spins of the reels that you don’t pay for that usually include some added feature like win multipliers and the possibility to retrigger the feature. You can get to free spins in different ways but it usually involves landing a number of scatter symbols or wins in a row in the base game. 

Win Multipliers

These symbols multiply your winnings by a given number. A multiplier worth 2x as part of a winning combination gives you twice the money you would have without the multiplier and so on. Although multipliers are very common, not all slots have them. 

Tumbling Reels 

Most slots by IGT have tumbling reels. The feature allows players to win multiple times on a single spin. You create winning spins that don’t seem to end using this feature. 

After choosing your bet and hitting the spin button, you may win when the spin forms left-to-right matches on the screen. After receiving your earnings, all winning symbols vanish from the reels, and those that remain slide down the screen. New symbols fall to fill the vacant spaces for a chance to create more winning combinations. You’ll win again when new winning combinations are formed. This goes on until you no longer create any more winning combinations. 

Pick Me Bonus 

A pick me bonus is a mini-game where you win prizes by picking from different selections. Sometimes you get to pick a determined amount of times and there are times when you get to pick until you pick the symbol that stops the game.

Welcome bonuses with free spins

Online casinos launch various offers designed to attract new players, granting them deposit bonuses and other perks. But if you’re a slot fan, you’ll want a welcome bonus with free spins. 

Free spins are a casino bonus that lets you play slots for free. Each spin is worth a predetermined value, typically between $0.10 and $0.20. The best part about this bonus is that, even though you can play for free, it can offer you real money rewards. 

However, free spins are often subject to wagering requirements that require players to wager their bonus several times before claiming their winnings. For instance, if you receive 50 free spins worth $0.20 each with a wagering requirement of 20x, you’ll need to bet $200 before being eligible for a withdrawal.

Slot promotions in the Keystone State

Fortunately, welcome offers aren’t the only way to enjoy slots with a bonus. Online casinos frequently release ingenious promotions that keep the fun going, including tournaments and deposit bonuses.

For example, players who join Caesars Pennsylvania can participate in regular tournaments with prize pools of up to $50,000. To secure a spot in the giveaway, you must play your favorite slots during the promotional period. Additionally, Caesars rewards players who deposit at least $40 with a $10 casino bonus. This offer has a wagering requirement of 10x for slots and a time limit of seven days.

You can also find multiple generous offers at BetMGM Pennsylvania. The casino regularly promotes slots by offering players bonuses in select games after they make a deposit. The wagering requirement for these offers is typically 20x. BetMGM regularly features tournaments that reward the highest-scoring slot players with cash prizes.

If you’re a high-roller with a passion for slots, we recommend trying BetMGM’s tournaments. However, if you prefer taking things slowly, you should claim a deposit bonus with Caesars or enter its giveaways.

Slot library and categories

Online casinos in Pennsylvania are constantly introducing new games to keep players entertained. Sites are neatly organized into different categories, allowing you to quickly find games and sort them by popularity, features, providers, and mechanics.

Currently, BetMGM has one of the largest slot sections in the Keystone State. It offers 460 games developed by top-rated providers, including NetEnt and Big Time Gaming. Games are divided into several categories, including “Featured”, “New”, and “Jackpots”. You can also sort slots by provider.

Caesars doesn’t have as many slots as BetMGM Pennsylvania online casino. Nonetheless, the selection still includes some serious heavy-hitters, including Megaways and jackpot slots. Overall, the portfolio features 222 games. Check the table below for a comparison between BetMGM and Caesars.

What You Need To Know When Playing Online Casino Slots

Even though bonuses are a fantastic way to enjoy online slots, they have a few restrictions. For instance, casinos typically limit the players’ maximum bet while using a bonus. This is done, so players take their time playing through the bonus. Casinos also restrict which slots are compatible with bonuses. The most commonly restricted games are jackpot slots, such as Mega Moolah, Wheel of Fortune, and Divine Fortune.

You should always take your time to read the bonus terms and conditions before opting into them. Failure to play by the rules can void your bonus and potential winnings. It can also result in account suspension in extreme cases. To maximize your potential, we also recommend understanding how online slots work and their underlying mechanics, such as RTP, volatility, and game features. Read more about these topics below:

Slot RTP and volatility

If you have ever played online slots, you likely came across these two terms. The RTP, or return to player percentage, is the average amount a slot will pay back to players during its lifetime. It’s worth noting that RTP doesn’t reflect your returns after a slot session, as the percentage is calculated from billions of spins.

On the other hand, volatility represents the slot’s balance between the winning frequency and the average win payout. Low volatility slots have small payouts and consistent wins, while high volatility slots have less common wins, which are significant, to say the least. 

RTP and volatility aren’t correlated, as slots can have different combinations of these parameters. Take Microgaming’s Mega Moolah and NetEnt’s Mega Joker, for instance. While they’re two jackpot slots with prizes worth millions, Mega Moolah has an RTP of 88.12% and low volatility, while Mega Joker has an RTP of 99% and high volatility.

Because they’re the most popular casino games you can play, slots are constantly being improved with exciting game mechanics that add a new layer of excitement to keep players coming back for more. Check out some of the best slot mechanics available at online casinos in Pennsylvania:

  • Megaways
    Megaways is a reel modifier mechanic that changes the number of paylines. Every reel can have two to seven symbols, resulting in up to 117,649 paylines on the best configuration. The most popular Megaways slots include Twin Spin Megaways, Medusa Megaways, and Bonanza Megaways.
  • Cluster Pays
    Instead of using paylines, Cluster Pays slots rely on clusters to trigger a win. These games typically have a 7×7 playing grid where players must obtain clusters with at least five symbols to win.
  • Cascading Reels
    Cascading Reels were made popular by NetEnt. This mechanic removes winning symbols, allowing new ones to fill the empty spaces, which can create consecutive wins in the same spin. It’s regularly paired with free spins, wilds, and other features.
  • Mighty Ways
    You could consider Mighty Ways a mix between Megaways and Cascading Reels. Winning symbols are removed from the reels, and two additional symbols are added, increasing the reel height to eight rows.

Myths About Online Slots In Pennsylvania

Many players will argue that online slots are rigged, but that couldn’t be further from the truth. Modern slots rely on an algorithm known as a random number generator (RNG), which ensures that every spin is entirely random and impossible to tamper with.

Gambling commissions like the Pennsylvania Gaming Control Board constantly test casinos and developers to ensure their games are fair. Additionally, regulators rely on the efforts of third-party auditors to confirm a slot’s fairness, such as eCOGRA and BMM Testlabs.

Bankroll Management When You Play Slots Online

Even though playing slots is fun, it requires being aware of your limits. Here are a few tips to help you enjoy slots responsibly:

  • Avoid chasing losses
    Chasing losses often leads to more losses. Chasing losses is betting more on the next spin or spoon to recoup losses. It’s best to log out and call it a day when you’re losing.
  • Set spending limits
    Before you start playing, set a budget and stick to it. If you run out of funds, take a break and try your luck another day. 
  • Set time limits
    Time can fly when you’re playing at online casinos. We recommend setting a time limit and stopping once it ends.

Players in Pennsylvania have access to some of the best online slots in the business. Casinos in the state have focused on developing exciting portfolios powered by top-rated iGaming providers. The best part is that there are plenty of bonuses to get you started, including welcome offers and regular tournaments. Don’t forget to stick to the bonus rules and play responsibly.
