What are Online Slots?

Online slots are the virtual version of your typical slot machine and are the most popular online casino game on the web. These gambling machines have three or more spinning reels that display symbols.

The goal is to spin the reels and have the symbols match up to form winning combinations. In order to play, you would place a bet, spin the reels, and hope for the best possible winning combination.

Over the years these machines have evolved and modern slots are more exciting than ever. The majority of slots are played online through online casinos. 

The best online casinos offer hundreds of slots titles to choose from, and these modern online slots can offer up to millions of dollars in rewards. This depends on the type of slot you choose, which we explain further down. 

Online slots are legal and regulated at a federal level in the United States. Right now you can play at an online casino legally in either New Jersey, Pennsylvania, and West Virginia. 

Random Number Generators

Modern-day slots are controlled by a random number generator (RNG) which is used to generate completely random number combinations. This controls the payback percentage for each slot machine. 

The RNG is programmed to have a specific payback percentage for its respective slot game. Usually, the more money the machine requires per bet, the higher the payback percentage will be. 

These payback percentages are rarely ever changed due to the amount of work it requires to make these revisions. 

Why Play Online Slots?

85% of online casino gamblers play slots nearly exclusively. Slots players are in luck when it comes to online slots. This is because:

  • Much better RTP on online slots (with many games at 98%!)
  • Generally higher jackpot payouts
  • Big bonuses available to claim
  • No need to wait for a machine
  • Huge variety of games 

Now with new casino technology, slots can provide even more entertainment for players and a much greater abundance of games with exciting graphics and special features.

Modern slots are the biggest draw toward US online casinos. 

Bonuses and Promotions

Oftentimes, online casinos will advertise their game selections by offering free play bonuses and free spins bonuses. 

These casino bonuses allow you to try out online casino games before registering with a casino or depositing your own money. 

Free play and free spins bonuses are a great way for online casinos to reel in new customers. There are so many casino options on the market, it can be tough competition for casinos. 

You can use the free play and spins to rack up some big cash prizes on different online slots games. It's risk-free and any money won from the bonus can be withdrawn as soon as the wagering requirements have been met.

The more you play, the more free spins you have a chance at collecting!

How to Win at Online Slots

Slot machines are much less intimidating compared to table games. There is not a huge deal of strategy involved. If you want to win the slot machine jackpot, you have to bet some money and for the most part, hope for the best. 

However, there are some slot machine tips that can increase your winning odds and help guide you to the best slot machines to play

High RTP percentage: It is very important to familiarize yourself with the slots you choose to play. Different titles have different return-to-player (RTP) rates. One important aspect of winning at online slots is finding a game that lets you win most.

  3. Manage your money! Like all casino games, don’t go chasing your losses. Look for slots with minimum bets that fit in your budget and set limitations for yourself. 

So how much are you willing to gamble? Knowing how much risk you are willing to take is an indicator of how much money you could walk away with. 

What kind of slots player are you? Are you someone who likes to go in big and take your chances at the progressive jackpot slots who are you okay will going in small and walking away with a bit at a time?

Once you have made this determination, then choose your slots accordingly.  

RTP & Volatility

Each game offers different payout structures and different volatility. These factors affect how much you could end up taking away with you from each slot game. 

Learning about the volatility of the particular slots titles will show you how frequently you can expect the slot to payout.

It’s also important to pay attention to each slot’s RTP percentages. 

What is RTP

RTP refers to the funds a player is expected to win back from a certain game over a predetermined amount of time. 

This percentage is a theoretical number usually used as a reference. The average RTP rate for online slots is 96% however, some online slots have extremely high RTP rates.

What is volatility

A game's volatility refers to how much risk is involved with that game title. 

If you are aware of the volatility of the particular slots you wish to play, you will have an idea of ​​how frequently you can expect the slot to pay out and how to win on slot machines. 

Low volatility slots will hit frequently but have lower payouts, while high volatility slots will hit less frequently, however, will payout in much higher amounts. 

Volatility refers to the risk involved with that particular game. Low volatility slots will hit frequently and have lower payouts, while high volatility slots will hit less frequently, however, they will payout in much higher amounts. 

Different Types of Slots

Video slots

What are Video Slots?

5-reel slots are also known as video slots and can offer a large number of paylines. Video slots offer many additional opportunities for winning combinations, making these games more exciting than the classic online slots. 

How do online video slots work?

In the same way as 3-reel slots, the paylines in video slots can be formed in a horizontal fashion as well as diagonally, along with additional formations on the screen. 

More extra features in 5-reel slots can include free spins, scatter symbols, multipliers, and bonus rounds. Extra features can potentially increase your winnings or at least earn you more opportunities to increase your winnings. 

Best video slots

Game provider IGT is known for supplying some of the best online video slots. Wheel of Fortune is one of the most popular video slots in the market now and features two bonus rounds that regularly see good wins, as well as a bonus wheel.

Triple Diamond also offers good payouts to players and features many multipliers, leading to big wins. Both of these games can be found at the majority of online casinos in the United States. 

Progressives slots 

What are progressive slots

The best slot machines to play are arguably the progressive slots. These slot machine jackpots titles can pay upwards of $1 million. However, the odds of actually winning are extremely slim.

Progressive slots build up until a lucky winner hits the jackpot and then the figure resorts back to the base. They come in all kinds of different shapes and forms, and can also include special features like free spins, multipliers, and wilds.

For example, the Big Series at Borgata NJ online casino has exceeded $2 million! 

How do progressive slots work

The progressive jackpot slots are made from a percentage of the money played in the slot titles included. As more and more players put money into the progressive jackpot, the total grows until one lucky winner gets the winning combination

The payback percentage on the other winning symbols will pay out less and not all progressive slots will payout the same. 

It is a good idea to learn as much as you can about the types of slots you wish to play, so you can know what to expect from them. 

Best progressive slots

Borgata Casino offers five different jackpots in their Borgata Big One Series, with over $2.8 million dollars to be won. These titles are:

  • Biker Pigs
  • Loot’EnKhamun
  • Going Nuts
  • Melon Madness
  • Luck ‘O The Jackpot 
Borgata Online

Classic slots

What are classic slots?

3-reel slots are also known as classic slots and are very similar to the earlier forms of slot machines. These classic forms of online slots are not as common anymore now that they’ve been replaced with modern games offering more paylines and special features.

Tech companies are still creating modern classic slots, however, for those players who still enjoy playing 3-reel slots.

How do classic slots work?

3-reel slots range from one to five paylines meaning there can be up to five different ways for the symbols to line up to form a winning combination. 

Best classic slots

One of our favorite classic slots is 88 Fortunes, which features five reels, free spins, a jackpot round, and over 200 ways to win. You can find 88 Fortunes at 888 Casino or Unibet.

Megaways Slots

What are Megaways?

Megaways slots come with a bit of a twist. Basically, these slot games give you hundreds of thousands of different ways to win by randomizing the outcome of every spin. 

How do Megaways work?

Megaways slots feature six reels, with a maximum of seven symbols per reel. At random, the number of symbols changes every spin which creates multiple different ways to win every time you spin. 

Best Megaways slots

Some of the best Megaways slots can be found at the following New Jersey online casinos: 

  • Golden Nugget 
  • 888 
  • Virgin 
  • BetMGM 

88 Fortunes and Monopoly Megaways are a couple of popular Megaways slots, both offering multiple bonus rounds and over 100,000 ways to win each time you spin. 

How to Choose which Online Slot to Play

Because of the wide variety of online slots to choose from, it may seem difficult to find a game that suits you best. 

For players who are looking to be entertained rather than seeking a big win, try looking at featured video slots that offer small but more frequent payouts than the jackpot slots. 

Progressive slots are great for those players who only care about the money. Playing a high stake game means there’s a small chance you could see a pot in the millions! 

If you’re someone in the middle where you want to win a lot of money but are not ready to risk too much to do so, try and find slot games that feature plenty of bonus rounds and wilds.

Bonus rounds usually result in some big wins, and all you need to wager to start is the minimum bet of 0.20 cents a spin!     

Online Slots Providers

What is a slot provider?

Slot providers supply online slot games to the operators of the online casino. These companies are responsible for the software, theme, and design of the online slot, including the RNG. 

Best slots providers

NeEnt and IGT are both powerhouses in the iGaming world when it comes to game providers. NetEnt is known for releasing slots with very high RTP’s and IGT has designed some of the best video slots in the market. 

What Online Slots payout best 

Typically the slot titles with a high RTP, are the games expected to pay out to players the best. 

  • Mega Joker by NetEnt, with an RTP of 99.0%
  • Jackpot 6000 by NetEnt with an RTP of 98.9%
  • Pixies of the Forest 2 by IGT, with an RTP of 98.83% 
  • Blood Suckers by NetEnt, with an RTP OF 98.0%

How to Play Slots for Free

Online casino registration bonuses will give you free money to try online slots games. You can keep what you win, however, you will be required to meet wager requirements before cashing out. 

You can play slots with no charge in demo mode but will not be eligible to win any real money during this time. However, it is a great way to learn slots and practice them! 

Note: If you wish to play for real money, please make sure that you meet all legal, regulatory requirements before gambling in an online casino. 

  1. Find a legal online casino in your state that you trust. 
  2. Sign-up! Registration bonuses will generally give you a certain number of free spins and bonus money to play free games online. These can be used to experiment with different games before risking your own money on them. Free slots bonuses often come with bonus rounds which can lead to even more real money rewards and even more free spins!  
  3. Once you have registered with some of your favorite online casinos, you will want to start racking up your loyalty points. Online casino loyalty points will earn you even more bonuses to play free games online.

While many slots players focus on offers for free spins, bear in mind that you can often get more free spins with bonus dollars.

Free spin offers only give you a certain number of free spins at a given wager value, and they also often limit the games you can play. 

If you are using bonus dollars from an online casino promotion, you can play with smaller wager amounts on the game of your choice.

While no deposit bonus dollars aren’t advertised as free spins, you can certainly use them for hundreds of free spins on slots games!

Where to find free slots

Ultimately, all online casinos will offer a demo mode to their game library but some might require you to have an account first before accessing the library. You can browse through these casinos by visiting our online casino reviews!
