How to Play Online Slots in Pennsylvania
It's easy to start playing online slots in Pennsylvania. At most online casinos, you can try games for free first. Once you've selected your favorite games, make a deposit (and be sure to collect all those casino bonuses, including a deposit bonus) and try real money slots.
Step 1: Choosing a Slot Site
The most important step is selecting a good casino. We review thoroughly every PA online slot site and its mobile app to save you time. We recommend signing up to a few sites so you can experience a range of games and promotions.
Step 2: Register Your Account
Opening a casino account should take just a few minutes. You will have to provide basic information such as your name, address and email address. You will also have to provide part of your Social Security number to prove you are 21 or older.
PA slot sites use the latest geolocation software to confirm you are within state borders when you log on and play, but you can download casino apps from anywhere in the country ahead of a visit to Pennsylvania.
Step 3: Make a Deposit
You will have to verify your ID before you make a deposit. You will normally be asked to supply a copy of your passport or PA driver's license to confirm your ID.
Once cleared, you can make a deposit and start online gaming. Head to the casino cashier and select a valid payment option. Not all VISA and MasterCard issuers will allow gambling deposits, so we recommend you use a prepaid card, bank transfer, or e-wallet such as PayPal . If the casino offers Play+, you will be able to register for the card and fund it with a credit card right after registering your casino account. PayPal is one of the most popular methods and you can find all PayPal online slots here on Slotsource.
Deposits are usually instant, and the best Pennsylvania online slot sites won't charge a fee. Some online casinos require bonus codes to collect your welcome bonus, while some will give you the bonus just for signing up. Make sure to collect all that you are entitled to!
Step 4: Selecting Games
Now it's time to play the best online slots in PA. Head to the lobby and find the slots tab. You can usually filter the lobby by game type or provider to find your favorite games fast. You can also add slot games to your Favorites list for easier access, or try out a demo play slot before you commit real money and start betting.
Step 5: Playing Games
Playing slots is simple. First, select your preferred coin size and number of paylines. Hit the Spin button and watch as the reels come to a random stop. You win money by lining up matching symbols on win lines, which are typically horizontal, though some slots have vertical or diagonal win lines.
You can also win prizes by triggering bonus features such as free spins. Progressive slots are now offered at most of the slot sites in PA. These offer huge linked jackpots when you trigger a special bonus game.
