By far the most popular and loved game amongst players, it is no surprise that slots make up the majority of PA casinos online game libraries.

The following is a list of Pennsylvania casinos online that have been granted slot licenses and approved by the Pennsylvania Gaming Control Board to offer a variety of online slots. Thanks to the PGCB, players never have to worry about a game being rigged as each title undergoes multiple tests to ensure it's safe and secure to play before entering any game library. Online casinos in the state have partnered with a number of world-known game providers including IGT and NetEnt, to provide players with the very best.

Slots online are extremely easy to play, just push the button on the screen, cross your fingers, and watch the symbols turn! You can decide how much you'd like to bet on each spin, starting as low as 0.10 cents and going as high as a few hundred dollars a spin. Generally, there are two types of online slots players in Pennsylvania have to choose from; progressive slots and traditional slots.

Progressive Slots

Progressive slots, also known as jackpot slots, are almost identical to the traditional version except for one difference which is giving the player the chance to win a huge payout on a single spin.

The jackpots are made by pooling a small amount from each bet made on the machine into one large pool that is released when a lucky player hits it. Most of the time there are smaller jackpots also offered with the grand one and while these slots offer worse odds than traditional, the jackpot can climb into the millions of dollars.

Traditional Slots

Unlike a progressive slot, it’s very rare that a player will see a score in the six to seven-figure digits unless placing a large wager but that doesn’t mean they can’t win plenty of cash. Traditional slots will offer static jackpots instead of the dynamic progressive jackpots.

Popular traditional slots in PA include:

  • Cleopatra
  • Gonzo’s Quest
  • Starburst
  • China Shores

Payline and RTP 


Basically, the object of slots is to line up the symbols that appear on the reel and depending on the number of paylines the slot includes, it will determine how many ways a player can do so. A lot of slots allow players to increase their number of paylines as they increase their bet. While classic slots like 3-Reel are pretty straightforward, some slots like Bonus Video Slots can feature hundreds at a time, however many will offer the player the chance to see the paylines line up with a click of a button. 


RTP is the Return To Player rate that comes from the percentage of how much money a game is taking in that will eventually pay back to players. It is not guaranteed that a player will get this money back or even win playing the slot, but for every $1 put into the game the slot will give back a percentage to someone. 

House edge (what the casino makes on a game) is the opposite of RTP.

For example, a slot machine has an RTP of 95%. This means the house edge is five percent and casinos will keep this from every bet as time goes on. If a player puts in $300 playing the slot, $285 will go to paying back players but, that doesn't necessarily include the player who put in the original $300. 

Casinos are able to set the RTP on a slot and in order for a player to win, they must be on the right side of the games RTP. 

Advantages of Playing Slots Online 

There isn’t much of a difference between the slots in PA casinos and those online. The games are pretty well the same in terms of the titles offered online and at a brick and mortar and a lot of the slots at PA land-based casinos will transition to the online casino. That being said, a lot of titles will be exclusive to online and offer players high-quality graphics and software that will fit perfectly on their desktop or mobile screen. Here are some advantages to playing online compared to going to a casino:

  • Fast: It is much quicker to log into an online casino than to get out to a land-based one.
  • Instead of walking around a casino trying to find a specific slot game to play, online players can change slots with the click of a button.
  • Instant payouts.
  • More slot games to choose from in online PA casinos. 
  • Players can play the online version of their favorite slot games from the comfort of their homes.

Mobile Slots

Mobile slots are probably the biggest advantage that comes with choosing to play slots online instead of at the land-based venue. All of the casinos online in PA so far have a mobile app available for download that also features a wide variety of online slots, accessible so long as players stay within PA borders. Mobile casinos do not have the storage space to carry as many games as the desktop sites, however, slots is one of the few games that are played best through a mobile device because of how perfect it fits on a screen, providing a very pleasant gaming experience! While mobile libraries are smaller they are still packed with a variety of slot titles, so it shouldn't be hard finding a game that suits you.
