Slots Online: Return to Player & Volatility 

Your chances of winning cash on online slots are based on the RTP percentage and volatility.

These will vary depending on the online slot game you are playing. 

What is the Return to Player

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, one of the most popular slots designed by the Swedish game provider NetEnt, has an RTP of 98%. 

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

What is volatility

Volatility is all about the risk involved in an online slot game. You’ll find slots with high, medium, and low volatility. 

High volatility slots offer big payouts occasionally.

Low volatility slots offer smaller winnings much more often.

You can still see a big prize playing either type, but the jackpots are found in the high-risk slot games.  

Different Types of Slots

The following are the most common types of virtual slots you will find in Pennsylvania right now.

Classic slots

What are classic slots?

Compared to the video slots, you won’t find many online classic slots to play anymore.   

How do classic slots work?

Classic slot graphics are limited, but they can still offer good bonuses and high payouts. 

Best classic slots

Double Diamond is one of the most basic slots in the market, but remains a player favorite!

The slot is designed by IGT and features 3-reels and one pay line.

How to choose which Online Slots to play

With such a huge variety of PA slots available to choose from, how do you know which one is worth depositing to?

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

Bonuses are important in slots because they give you a better chance of increasing your cash.

For example, an online slot that features scatter symbols could unlock free spins. This could lead to entering a bonus round and potentially doubling your bankroll.

If you like to take risks and not pay attention to your bank account, you want to look at high volatility slots.

Low volatility slots are great for the players who have a budget and aren’t looking for a huge jackpot.  

The best way to do your research on a specific slot is to test it in demo mode.

This way you’re spending nothing and can learn what each symbol means and how often the bonus rounds come along.
