Slot Games That Fit Your Style

You can find all the latest and most popular online slots at all the top casinos in PA. 

However, finding the right slot game(s) for you is really all about your preferences and how you enjoy playing. 

What to Pay Attention to When Choosing a Slot Game

With such a huge variety of online slots available to choose from in Pennsylvania, how do you know which one is worth spending your money on?

In general, you want to look for slot titles that have a high RTP percentage and bonuses like free spins

Let’s take a look at other factors you should think about before choosing a slot to play. 

1. Look Out for Volatility 

If you like to take risks and don’t care about the money you’re spending on the game, you want to look at high volatility slots. These types of games, offer large payouts but not as frequently as low to medium volatile slots. 

Low volatility slots are great for players who have a budget or might be new to gambling online. They offer frequent small payouts, but it’s rare to hit a jackpot on one of these slots.   

Jumanji Gameplay

If you want a slot that has the best of both worlds, check out medium volatility titles like Jumanji. Medium volatility slots offer frequent payouts smaller than high volatile slots, but greater than low volatile slots. 

High Volatility SlotsMedium Volatility Slots Low Volatility Slots 
Raging RhinoJumanjiBlood Suckers II
Dead or AliveCleopatraButterfly Staxx
MontezumaDivine FortuneStarburst

2. Pay Attention to RTP 

Return To Player (RTP) is is the amount of money you will get back from a slot over time, represented as a percentage.

The higher this number is, the better

Blood Suckers has an RTP of 98% which is arguably the highest in the PA market. 

When looking for an online slot to play, we recommend slots with an RTP of 96 to 99%

3. Graphics and Sounds

As technology advances, game providers are getting more and more creative with the online slots they release. 

Instead of just being about the symbols on the reels, video slots are telling stories through the game.

A great example of this would be Wild Worlds, one of NetEnt’s more recent titles (2019), where players will spin the reels in the good guy’s headquarters, and battle evil villains in different bonus rounds. 

If you’re the type of player who prefers a simple, less animated game, stick with the classic 3-reel slots.

4. Themes 

You can find online slots to play just based on the theme of the game. Christmas and Halloween-themed slots tend to roll out towards the end of the year, but some stay available all year round! 

If Christmas is your favorite time of the year, why not check out Jingle Spin

Or, if you aren’t looking for a seasonal game, there are themes you can choose based on animals, movies, and even celebrities. 

5. Stick to a Budget 

Typically, the more you wager on a slot game, the more you could win. This is why having a budget while you play is very important. 

You want to establish your budget before you hit the slots. This will help you to avoid chasing your losses and wager more than you originally wanted to. 

Remember, always play smart

6. Risk & Payouts

What Types of Slots are Out There? 

We’ve listed the different types of online slots you can play and what makes them so popular in Pennsylvania. 

Take a look at our list below. 

Number of reels 

Reels are the vertical lines displayed on the slot and what holds your symbols.

Every online slot has a minimum of three reels, with the majority of titles featuring at least 5 to 7.

3-Reel Slots

These types of games are often referred to as classic slots because most of the titles have been around on casino floors for a long time before debuting online.

3-reel slots often have little to no features available and between one to five paylines, but still offer users the chance to win big. 

5-Reel Slots

Most video slots have 5 reels and are probably the most popular in PA. Compared to 3-reel slots, you’re getting a lot more paylines and bonuses which means even more chances to win! 

7-Reel Slots

Even greater than 5-reels are 7-reel slots. These types of slots can have anywhere between 20 to 50 symbols and are rare in PA. 

Game Type

Classic Slots
Online Slots in Pennsylvania

Classic slots have 3 – 5 reels and usually use basic symbols, like fruit or numbers, with very little animation.

Compared to the video slots, you won’t find many online classic slots to play anymore. These slots usually offer limited features, but they can still offer good bonuses and high payouts. 

Classic online slots tend to have the lowest min/max bets, which is attractive to new players.  

Video Slots

Video slots are multi-reel slots that have numerous paylines. They are the most common slot type and offer all kinds of ways to win! 

These slots feature multiple themes, strong visuals, and different bonus rounds. 

Progressive Jackpot Slots

Slot games that offer a jackpot prize that increases every time a player spins.

Every time a player deposits on a progressive slot, a percentage of their bets go towards the jackpot. Over time this number can reach the millions until one lucky person hits it, and then the jackpot resets. 

By far the most popular progressive slot in the market right now would be Divine Fortune

Divine Fortune Gameplay

Megaways Slots

Big Time Gaming was the first provider to give us the popular Megaways slots

These slots can have up to 117,649 paylines for you to win on. 

Remember, the more paylines, the more matches; the more matches, the more winnings. 

Bonus Buy Slots

Some online slots actually give you the option to buy your way straight to the bonus round. If you’ve found a bonus buy slot, you’ll notice a large button usually on the side of the game that reads “Buy Pass.”

To buy the bonus, the slot requires a large wager of around 60x to 100x your wager. So a $1 wager could mean $100 to get yourself into the bonus round. 

While the bonus round has the potential to increase your winnings significantly, it’s also possible to walk out of a bonus game with nothing. 

Typically, bonus buy slots are great for high rollers or a player who doesn’t mind spending a lot with no expectations. You should not enter a bonus round convinced you’re going to walk away rich. 

*Did you know?

SugarHouse and BetRivers were the most popular online casinos in PA in 2020. Together they saw a total revenue of $19.3 million in December. $15.9 million of that came from online slot players.

Is there such a thing as a “slot strategy?”

Your strategy going into slots is going to be a lot different than any other casino game online. Slots are based purely on luck, but there are things you can do to optimize your bet and hopefully see some big wins.

Next time you’re playing slots, keep these points in mind: 

  1. Set a budget! It’s very easy to get carried away while playing slots. Look for games with low minimum wagers and most importantly, do not chase any losses!

How do Slot Games Work?

To be able to succeed at playing any game, you need to understand the fundamentals first. 

Here’s how the average online slot game works:

  1. Place your wager and hit spin.
  2. Watch the reels spin and come to a stop. 
  3. On each reel, you will notice the symbols line up. 
  4. If the reels have matching symbols along the paylines of the game, you’ll win a prize. 
  5. If a reel has a Wild symbol, it will replace a symbol along the payline to increase your chance of winning. 
  6. If you receive enough Scatter symbols in your spin, you’ll receive a bonus round. Bonus rounds come in multiple differentiations based on the game being played, but the most common are free spins. 
  7. If you are playing a progressive slot, you will be playing towards the ever-increasing jackpot in the game. The jackpots in progressives go up each time a player spins the reel.
