Casino bonus eligibility: You should be able to claim a casino bonus when you play online slots for real money. Not all slots are eligible, however. We will flag any games that won't count toward a bonus contribution.

Types of Online Slots Machines

The beauty of online slot machines in Pennsylvania is that there is such a wide variety available. You can choose a simple classic slot with no bonus features or hit the multiway slots and play 4,000+ paylines at once.

Here are some of the most popular online casino slots types you will find out there.


3-Reel: Many older style slots will have 3 reels and usually 1-3 paylines. 3 reel-slots tend to have minimal bonus features as well.

5-Reel: Most modern slots have 5 reels. It allows for more paylines and additional symbols such as scatters and wilds. The volatility of 5-reel slots depends heavily on the arrangement of high-paying symbols.

6-Reel: 6-reel slots have more rows than conventional 5-reel machines. They also tend to have a lot more paylines. It's not unusual to find thousands of win lines in a 6-reel slot.

Classic Slots

Classic slots utilize old-school symbols such as fruit and bells. They are reminiscent of vintage machines you might find in a Vegas or Atlantic City casino. Classic slots will also have nostalgic sound effects, but bonus features will be hard to find.

Video Slots

Video slots first appeared in land-based casinos in the 1970s. They use microchips to determine the outcome of each spin instead of a mechanical device.

All online video slots are governed by Random Number Generators (RNGs) that keep the spins fair. You may also find video footage or animation that is integral to the gameplay.

Progressive Slots

Progressive jackpot slots work differently than conventional online slot machines. A small portion of your wager goes toward a bigger jackpot. You can win the jackpot by triggering a random bonus feature. Progressive jackpots can be fed into by thousands of players. The longer a jackpot goes unclaimed, the bigger it gets.

3D Slots

3D slots boast immersive graphics and animated symbols. In some branded slots, you can also enjoy video footage from music videos or Hollywood movies. The increased power of 3D slots means the bonus features are usually more original than in regular video slots.

Multiway Slots

Multiway slots award cash prizes when you match symbols anywhere on adjacent reels. Because multiway slots don't use standard paylines, there are often many more ways to win. Some multiway slots have more than 100,000 possible win lines.

Online Slot Bonus Offers in PA

The best casinos for online slots in PA usually carry some kind of promotion. You will find top deals at all our recommended casino sites here at

Free Spins

As a new customer, you can usually claim free spins on a nominated slot. You will bank any winnings in a special prize pool. The winnings are released once you wager the amount several times over on the casino site.

Slot Tournaments

Some PA online casinos run slot leaderboard challenges. Play a set number of spins on nominated slots and try to win as much as you can. The highest winners will share prize cash or gifts such as gadgets and holidays.

Common Slot Bonus Features

Slots are easy to play, and many games have the same features. Here are some common online slot features to look for:


Scatters are special symbols that award prizes wherever they land. They don't form part of a winning combination and pay out separately. Scatters usually trigger a bonus feature too if you land enough on the reels at the same time.

Wild Symbols

Wilds act like jokers and fill in the gaps in incomplete combinations. Some online casino slots also feature wild varieties that have special characteristics:

Walking wilds: Walking wilds will move across the reels, one reel at a time. After each move, you are awarded a free re-spin.

Transferring wilds: Transferring wilds appear in online slots with more than one reel set. The wild symbol will copy and transfer over to the same spot on a second or third set of reels.

Wild multipliers: Some wild symbols carry special multipliers that are added to your payout. Multipliers can accumulate if you land more than one wild on a single spin.

Trail Bonus

A trail bonus is a mini-game which awards payouts and free spins the further your progress. There is usually a big jackpot if you make it to the end of the trail.

Tumbling Reels

The Tumbling Reels feature is sometimes known as Avalanche Reels or Cascading Reels. On every successful spin, the winning symbols vanish and are replaced by those sitting above on the reels. You can then make more winning combinations indefinitely. Some of the best online slots with Tumbling Reels award multipliers that increase with every successive winning spin.

Nudge and Hold

Nudge and Hold are features in some classic slots. At random, the Nudge and Hold feature will trigger. You can hold any reel you like for the next spin, or nudge one or more reels up and down to complete a winning payline.


Volatility is a feature of all online slots. Low-volatility slots pay out small prizes often, while high-volatility slots pay out large prizes less frequently.

You can judge a slot's volatility by practicing with free-play games or by checking the paytable. The spread of jackpot payouts will give you a clue as to whether a slot is volatile or not.


All online slots have an RTP (Return to Player percentage). This is the long-term payout that a slot will theoretically make to players. You can usually find the RTP in the paytable. An RTP of 95-99% is good for an online slot. A game with an RTP lower than 95% should be avoided.

Popular NetEnt slots include Starburst, Gonzo's Quest and Jack Hammer 2. NetEnt also provides record-breaking progressive jackpot slots such as Divine Fortune and Mega Fortune.
