With so many certifications and regulators, players can feel confident that playing at legal online casinos in the US is safe and secure. 

*Did you know? Offshore and illegal casinos are not held to the same standards as legal online casinos. As such, you cannot be sure that your personal information is secure or that their games are fair for players at these offshore/illegal casinos. 

Slot Games That Fit Your Style

There is a slot game for every type of player out there, so you’ll be sure to find one that fits your playing style. You can try a number of slot games in demo mode at many of the top online casinos out there, or grab a bonus and start earning your way towards some big wins today. 

What to pay attention to when choosing a Slot game?


Every slot has some type of theme, and this is meant to draw in players with varying interests. You’ll find slots that have themes based on colors, tv shows, music, movies, fairy tales, and so much more. Slot providers are always coming out with new and innovative slots with different themes each month. 


While many of us play slots online for fun and entertainment, it’s the lure of winning a few extra bucks is enticing. Some of the best online slots have jackpots worth in the hundreds of thousands. And yes, people have won them while playing at the best slot sites in the US. 


Every time you gamble there is always some element of risk. There is never a guarantee that you are going to win when you play. Some people call this risk “the thrill.” You can assess “the thrill” of the game by looking at its volatility and RTP

Look out for volatility

Volatility is the riskiness of a game. It has to do with how big the wins are, and how long you have to wait, on average, to win. If a game has high volatility, that means you may expect long dry periods of no hits before you win. But if you do win, payouts are bigger in high volatility games. 

Pay attention to 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 more than $100, and you may lose more.

What’s your budget?

If your goal is to play to have fun, you won’t need a substantial budget. However, if your goal is to play slots online to win big, the more you bet the more you win. This goes for both the amounts of wagers made and the amount of time spent playing. 

In order to maximize your wins, you will want to “Bet Max” which will place the maximum amount of wagers allowed on all paylines. This will increase your chances of matches on each payline. 

Additionally, you will usually need to play for an extended amount of time in order to trigger a game’s bonus game. Bonus games are generally the best way to increase your winnings on online slots. 

Did You Know

Real-life slot machines pay out more regularly than virtual ones! Yes, but only for a few select devices. Many gaming machines have a predetermined percentage. Set a target of 80%. The odds of winning are the same no matter how many times you spin the reels. Because they aren’t identical, casino machines may pay out more yet have fewer wins than online slot games.

What Types of Slots are out there?

So now that you know a bit more about how slots work, it’s important to understand the difference between specific types of online machines you will find. From 3-reel classics to the best offering in video slots casino sites, we cover them all here.

What online slots pay real money? Below is a list of slot types, what they offer, and why you might like them.

3-reel slots are also described as classics because they’re digital representations of physical slot machine games that have been popular for decades.

Symbols are spread across three reels and, in general, these slots have between one and five paylines. Their no-fuss dynamics make them popular with those that love action. Red, White, & Blue is an example of a popular 3-reel slot. 

5-Reel Slots

This creates more opportunities in terms of ways to win, payout potential, and bonuses. One of the most popular 5-reel slots you’ll find is Gonzo’s Quest

6-Reel and 7-Reel Slots

Just when you think the game creators can’t possibly keep adding to the excitement, they do. You can find slots today with even six or seven reels. Usually the more reels, the more chances you have to win. 

Game Type

Fruit Slots

Fruit slots are, as you’d expect, filled with fruit. These games typically fall into the classic category as well as the 3-reel category.

There are fruit slots with five reels. However, these nostalgic hits usually have three reels packed with cherries, lemons, oranges, and other juicy treats.

These extra ways of matching decrease the risk and increase the thrill of playing. 

Bonus-buy Slots

How to increase your chances of winning?

Many casino games take a certain amount of skill to play. But when playing slots, it’s more a game of luck. This is especially true with online slots as they use RNG software that assures players the outcome is always random. 

But there are some things you can do to help increase your chances of winning while playing. 

Here are our suggestions: 

1. Read our reviews

Our team regularly reviews the best online slots to let you know the ins and outs of the games before you play them. We rate online slot machines based on their graphics, RTP, volatility, bonus features, and numerous other factors.

2. Watch Streamers play

Another easy thing players can do is watch online streamers play new slot games to show the game’s features. This will allow you to watch someone else play the game in real-time without having to spend any of your own money.

Streamers will walk you through the paylines, min/max wagers, and symbols, and let you watch the bonus game/free spins play out.

This can be an excellent way to see if an online slot offers features you enjoy or not.

Popular streamers for online slots US include:

3. Consider the slot payout

Slot machine games are very different, with some paying out better than others. While there may be many reasons why you might go for a lower-paying game, it’s important to know what you are getting into. but for the new player, sticking to high payout slots is a good idea.

4. Is There Such a Thing as a Slot Strategy?

While it might seem that it is very little, or almost no, strategy to playing slot games, that’s not truly the case. It’s true that slots are predominantly a game of luck, but there are some strategic moves players can make to increase their odds. 

Place smaller bets on each payline to increase your chances of making matches on a payline. This will stretch your budget a bit more than if you place “Max Bets” on each payline.

The laws of probability are against you to get continuous wins on the same game. Try playing various slots to increase your chances of winning. You might also find a new game that you like that you hadn’t played before. 

A small win is still a win. Don’t continue to press your luck when you’ve already won. Know when to stop, and always play responsibly.
