 What are online slots? 

Slots is far and away the most popular game in US casinos, both online and land-based casinos. While slots is a game of luck, there are many choices you can make that will drastically increase your chances of winning.

How random are online slots?

All online slot games use a RNG - Random Number Generator. RNG’s are used to ensure a game’s fairness, so that the result is always random regardless of previous results. 

How much can you win on online slots?

Online gaming should always be first and foremost about having fun. But there’s always the thrill of the idea of hitting the jackpot! Keep in mind, hitting the large jackpot is not the norm. However, it is easy to rack up numerous smaller wins if you are playing the right game with the right strategy. 

How are online slots legal?

Online slots are legal in all states that allow online casinos. Currently that consists of:

  • New Jersey
  • Delaware
  • Pennsylvania
  • West Virginia
  • Michigan

Why play online slots?

There are several reasons why players are drawn to online slots over other games.

  1. Easy and convenient to play
  2. A wide variety of games
  3. High RTP
  4. Easy to make small wagers

How to play online slots 

Online slots are still a game of luck. However, there are some strategic steps  players can make to give their winnings a boost. 

Players should focus on:

  • Their chances of winning 
  • How much they can potentially win

Here are some suggestions you might want to try when playing online slots. 

Find Slots with High Payouts

There is certainly no shortage of slots available to play. But remember, not all slots are the same!

You want to find slots with a high RTP (Return to Player) percentage. This will increase your chances of winning as you play over a set amount of time. 

A game’s RTP can usually be found under “settings” or “help” links of the slot game.

Understand a Game’s Volatility

In addition to RTP, do some research on games and find ones that have low volatility. You can think of volatility as the “risk level” of the game. The lower the risk, the higher your chance of winning - and vice versa. 

The best way to find a game’s volatility is to use Google and let its search engine help you find a specific game’s risk level. 

Find the Best Promotions

Almost all online casinos have some type of promotion going on, many for online slots. 

View these offers as a form of “free money” for you to get used to the games and play at no cost to you. 

Play Progressive Jackpots

Progressive slots are the best for players looking to hit it big

The jackpot increases each time a player spins the reel, so these really have the potential to get big fast. 

Keep in mind that progressive jackpots have high volatility, so your chances of winning aren’t as high as they would be on other games. 

Max Out Paylines

Paylines are lines where the symbols match up. If you wager a small amount on each payline, you will increase your chances of winning on at least one of them. 

This is the opposite of Bet Max. Bet Max will use up your funds faster, even if the payout might be larger if you win. Only use a game’s Bet Max feature if you have the funds to do so. 

Stop When In Profit

The key to any game is stop when you’re ahead. 

Even if you haven’t won as much as you think you can if you continue, coming out with more money than you had is a win. 

Play to have fun, but also play responsibly

RTP & Volatility 

A game’s RTP and its volatility should be thought of as opposing forces. Games with a high RTP will have a low variance, and games with low RTP will have a high variance. 

What is RTP 

RTP stands for Return to Player. This is the amount of money you can expect to win back over time in any given game. For example, if a game's RTP is 97%, you can expect to receive 97% of your bets returned as wins. 

This means if you bet $100, the average would be to win $97 back. Of course, you may win a lot more than $100, and you may lose more than that.

What is volatility

Volatility is the amount of risk in the game. If a game has high volatility, that means it's risky: you may win a lot at once, but you'll probably have long periods of play where you don't win at all. 

So decide if you want lots of action. If so, then find a game where a high RTP score is found. That means it will have low volatility. You can expect frequent, smaller wins.

If you're the kind of player who wants to go for the big win, and you can afford steady losses along the way, then find a high volatility game. There you'll see a lower RTP.  

Different types of slots

There's never a lack of variety of online slots. You will never have to wait for your favorite game, and no one will ever cut in line! The online casino providers you see listed on our site are prepared for thousands of guests at once, which means you get your game whenever you want. 

Video Slots

What are Video Slots

Video slots are the most common slot type and offer numerous ways to win! You’ll find a huge selection of video slots at all the top online casinos across the US. These slots feature multiple themes, strong visuals, and different bonus rounds. 

How do online video slots work

Video slots often have storylines and include exciting graphics and animations. They are without a doubt the most popular types of online slots. 

But the secret to video slots is the paylines. Bet a lower wager on each payline to increase your chances of matches and potential wins; while not spending all your money too quickly. 

Best Video Slots

Blood Suckers II and Gonzo’s Quest are two of the top video slots around. Both games feature impressive graphics, free spins, wilds, and scatter symbols. You can find these games at SugarHouse, which are provided by top software developer NetEnt. Be sure to take advantage of any promos they have available. 




Progressives slots 

What are Progressive slots

Progressive slots have an ever-increasing jackpot each time a player pulls the reel. Because of this, it is not uncommon to see progressive jackpots reach the hundreds of thousands.

How do Progressive slots work

Every time a player spins the reel on a progressive slot, a percentage of their wager goes towards the jackpot. This process continues until someone hits the jackpot, and then the game resets and starts over.  

Best Progressive Slots

Here are some casinos we recommend that currently have huge jackpots on progressive slots right now!



Classic slots

What are classic slots?

Classic slots are 3-reel or 5-reel slots that are virtual recreations of the original and more familiar slot machines. Their symbols generally look like numbers or fruits, and generally less animation. This type is probably the easiest to grasp an understanding of how to play.

How do classic slots work?

Classic slots play with one to five paylines and have few reels. Because of this there aren’t as many combos to win as there are with video slots.

Best Classic Slots

Some popular examples of Classic Slots include:

  • Flying Ace - A classic three row, three column slot. This one is VERY easy for new players to learn quickly.
  • Book of Pyramids - Another straightforward game, with an RTP of 97.31%.
  • Diamond Strike - This classic slot is one of the few examples of a low variance classic slot, and also maintains a RTP of 96.48%.

Classic slots are available at almost all online casinos. 



Megaways Slots

What are megaways?

Megaways slots give you a changing number of symbols within a single game. Each reel can have anywhere from two to eight symbols. This creates loads of possible combinations that can expand into hundreds of thousands of ways to win.

How do megaways work?

The easiest way to explain how Megaways work is by looking at the game’s reels. The slots essentially have changeable reels where the symbol height on each reel varies with every spin.

How to choose which online slots to play

With so many different kinds of online slots to choose from, it can be difficult to find the right one for you. 

Here’s some suggestions to help:

  • A game with a high RTP will give you more small wins, but might feel it is moving at a slower pace. These games are better for casual players who enjoy the thrill of racking up smaller wins. 
  • Progressive jackpots are for those looking for lady luck to be on their side for that big win. These games are for players who don’t mind losing often knowing that chance is greater for a bigger payout in the end. 
  • Themed slots with good bonus games are best for new slot players. This will give you some sense of familiarity as you get used to how slots work. 

Finding the right slot to you is more about trial and error than anything else. Test several games out before settling for one specific game. 

Don’t forget to take advantage of free spins bonus offers! This will help you find the right game for you with no out-of-pocket costs.

Online Slots Terminology and Special Features

It’s important to make sure you understand basic definitions of terms that you will see while you play any game. Below is a brief glossary of terms to explain what each word means. 

Paylines

Paylines are the rows on the slot game that rewards the player a payout based on how the matches line up. The amount of paylines a game has varies by game and developer. 

Multipliers

Multipliers are bonuses found often in slot games that will increase a player’s winnings by a specified number. (x2, x5, x10, etc.)

Wilds

Wilds are bonus symbols that are used to create winning combinations based on the symbols around it. 

Scatter Symbols

Scatter symbols usually activate bonus features of the game. This can come in the form of a bonus mini-game, multipliers, or substitute other symbols on the screens for those that help create matches. 

Free Spins

Free Spins allow you to spin the reels without wagering anything. These can come as bonus offers or won while playing the game. 

Bonus Rounds

Bonus Rounds are perhaps the most exciting thing about playing online slots these days. A bonus round is a mini-game inside the game that usually offers a good chance to substantially boost your winnings. 

Symbols

Symbols are the items lined up on each payline that you are attempting to match. The symbol will be defined by the theme of the game. 

Reels

Reels are the spinning columns being run to match the symbols. Most online slots have between three and five reels. 

AutoPlay

AutoPlay allows a player to set a specified number of spins to spin on their own rather than manually. 

Multiplier

Multipliers are generally attached to a symbol that, when matched, multiplies the player’s winnings by that number. 

Maximum Bet

Maximum (or Max) Bet is the largest amount a player can wager on a payline. The concept is “the larger the bet, the bigger the payout.” 

Conclusion 

In these times of rapidly changing technology, there’s one thing quite evident in the world of online gambling: these ain’t your grandma’s slots!
