Choosing winning slot machines at the best PA online casinos

While there are no sure-fire ways to guarantee wins when playing slot machines, there are some strategies to improve your odds.

This page provides a full breakdown of real-money online slots, including some tips that you can use to hopefully win more often.

By the end, you will have a better understanding of how slot machines work, the best ones to play, and where to play them.

Selecting the best PA online casinos

Pennsylvania is home to over a dozen online casinos that are regulated by the state’s Gaming Control Board, but they aren’t all equal.

First and foremost, it’s crucial that you choose an online casino that is regulated because those sites utilize Random Number Generators (RNGs), which make for fair payouts.

Below, you will find a table featuring the best PA online casinos, their sign-up bonuses, and the estimated total number of slot titles that they offer:

PA online casino Sign-up bonus Total # of slots
Bally Up to $100 money back guarantee 230+
BetMGM 100% deposit match up to $1,000 + $25 on the house 1,000+

One of the very first things to look for when choosing an online casino is the brand’s welcome offer because some are more favorable than others. After that, slot players will want to see a wide range of slot titles to avoid staleness. BetMGM Online Casino easily takes the cake in this category, offering users over 1,000 slot titles. You can access BetMGM’s welcome offer here.

An underrated aspect of selecting the top online casinos in Pennsylvania is whether or not they offer a Demo Mode on their slot games. This allows you to try different slots for free to see how they perform.

There are various types of slot machines (which we’ll cover below) available to play online. Features such as bonus rounds, free spins, special symbols, and even the overall theme could sway your opinion on a slot. Demo Mode lets you narrow down your search without risking real money.

Types of slot machines: RTP, jackpots, etc.

As you probably already know, online slot machines come in many different forms, and there are some key terms to understand in order to maximize your odds of winning.

RTP: What does it mean?

Let’s begin with what RTP stands for. The acronym indicates the game’s average return to player percentage. But what does that mean?

Well, it signifies the likelihood of winning at a particular online slot based on previous slot wins. Let’s say an online slot’s RTP is 95.60%. This means that the game pays out $95.60 for every $100 wagered on average.

Now, it’s important to remember that a slot’s RTP is not the be-all, end-all. It is simply an indicator for what the theoretical payout percentage is on a given slot.

The higher the RTP, the better chance you have of winning on each spin. We encourage you to look for slot machines with RTPs of 95% or above.

Understanding slot volatility

Understanding a slot machine’s volatility is another way to choose the best slots to play.

Let’s take the following as an example: If a slot is listed as having low volatility, then it pays out smaller wins at a more frequent rate. Meanwhile, a slot with high volatility pays out less often, but the winnings are larger.

Sometimes, a slot’s volatility can be referred to as either risk level or variance. Slots with higher volatility come with more risk, and patience becomes key, as you must wait a bit longer for the bigger wins.

We recommend playing slots with lower volatility as a new player because it requires less patience. To locate a slot’s volatility, it’s best to search the slot title on your preferred search engine (e.g., Slot X volatility).

Jackpot slots come in different forms

The two kinds of jackpot slots that you’ll find at the top online casinos in Pennsylvania are fixed and progressive.

  • Fixed jackpots: A non-progressive jackpot slot, or a fixed jackpot slot, makes it clear what the maximum win is—and it never changes.
  • Progressive jackpots: When playing these kinds of jackpot slots, each spin that doesn’t win will contribute to the growing jackpot. Meaning, the jackpot grows rather than being fixated at a certain amount. They tend to hit less often, but when they do, they’re normally quite large.

How to win at slots: Choosing the right slot

Again, there is no concrete way to guarantee winning when playing slot machines, as it is gambling. Yet, we advise you to consider the following strategies to give yourself better odds of winning:

Picking a slot

You can begin your slot-picking process by simply choosing one that stands out to you. This could mean the game’s theme, title, or something else that appeals to you.

From there, we recommend looking into the slot’s RTP%, volatility, as well as the minimum/maximum bets and payouts. We also encourage you to navigate to the casino’s ‘Promotions’ tab to see if any specific slots are linked to current bonuses. Lastly, try Demo Mode before risking your hard-earned money.

Bankroll limits

This is important because the goal of playing slots is to have fun, not necessarily to win a life-changing amount of money—because that’s incredibly rare.

Thus, set a budget to ensure that you don’t lose more than you can afford. Not only that, but you should bet wisely. Meaning, don’t just play the max bet every spin. Take it slow, and learn more about the slot machine as you play. Advanced slot players recommend not betting more than 1-2% of your total bankroll on a given spin.

In-game strategies

Since slot machines don’t really require skill because you simply spin the reels and let the game play out, your in-game strategies are rather limited.

But you can do your homework prior to playing. Get the slot’s RTP% and volatility level. Then, try to gain a better understanding of the game’s key features, such as multipliers, bonus rounds, wilds, and whatever else that’s unique about the specific slot.
