Why Play Online Slots and Are They Safe?

Online slots are both fun and safe. You receive the same entertainment as you would on the Vegas Strip from the comfort of your own home. 

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.

What to pay attention to when choosing a Slot game?

You now have your pick of thousands of real money online slots to choose from. 

But with so many choices, how do you know which one to choose? 

Here’s our advice below. 

1. Game Theme 

You can find a number of slots to play just based on the theme of the game. For example, some slots will be based on a certain type of animal, like Cats, or maybe a rock band, like Guns N’ Roses. There are even slots based on classic movies, like Baywatch! 

There are so many different themed slot games, it would be difficult for a player to not be able to find a slot that fits their style. 

2. Online Slot Payouts – Play the best online slots real money!

It’s no secret that playing online slots for real money has the potential to earn a player some big bucks. Take into consideration how large of a jackpot you could potentially win from the slot before you start investing real money into it.

3. Risk

All players should know that there is always an element of risk when playing any casino game. While it is great to win, there is no guarantee that you will. 

A great way to evaluate the risk of a game is by looking at its volatility and RTP. 

Watch below: Top 10 Mistakes Slot Machine Players Make with Mike “Wizard of Odds” Shackleford

In this two-part series, Mike Shackleford, also known as the “Wizard of Odds” gives his top 10 list of mistakes that slot machine players make.

  8. Over-tipping on jackpots
  9. Leaving a game in a high state
  10. Leaving credits, or money, in a machine

Part 1

Part 2

4. Lookout for slot volatility

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

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. 

Right in the middle are medium volatility slots. These will pay out more often than low volatility slots but with smaller amounts compared to high volatility slots.  

5. Pay attention to online slot 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.

Check out our list of the best High RTP slots here.

6. What’s Your Budget? Play Online Slots Real Money No Deposit

The best rule of thumb when it comes to online slots for real money is to only play if you can pay. 

Never spend money that you don’t have. Online gaming should be seen as a means of entertainment and not an attempt at a get-rich-quick scheme. 

Players can enjoy playing with online slots real money no deposit bonuses at a number of top US casinos!

You’re going to find a huge selection of slots at any online casino you visit in America. These most commonly range from 3-reel classic slots, 5-reel video slots, and jackpot titles. 

Let’s take a look at each one below. 

Number of Slot Reels

Real money slots online come in all shapes and sizes these days. The number of reels a slot has will determine how many ways there are for a player to win. 

3-Reel Slots

3-reel slots are also known as Classic Slots. These are closest to the original slots from yesteryear. You’ll find that 3-reel slots have between one and five paylines. 

5-Reel Slots

The majority of new video slots produced these days are five-reel slots. These games give players more paylines for more potential matches and possibly larger wins. 

6-Reel and 7-Reel Slots

As providers seek to be more innovative and present new types of games to players, you may run across a slot that has more than five reels. These are not very common as of now, but they are out there.

Game Type 

Classic Slots and Fruit Machines

3-reel slots or classic slots 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. If the classic slot is fruit-themed, you might hear it called a Fruit Slot or Fruit Machine.

Video Slots

Video slots can offer many additional opportunities for winning combinations, making these games more exciting than the classic online slots. In the same way as classic 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 video 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. 

Progressive Slots

Progressive slots will build up a jackpot prize until a lucky winner hits it, 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. The jackpots are made from a percentage of the money wagered on the game. As more and more players put money into the progressive jackpot, the total grows until someone gets the winning combination. These slots can pay upwards of $1 million, however, the odds of actually winning are small. A few of the most popular progressive slots in America are Mercy of the Gods and Divine Fortune


Megaways slots are still new to the United States and 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. Megaways 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.

Bonus Buy Slots

If you’ve ever wondered if it was possible to fast forward right to the bonus round in a slot game, then bonus buy slots might be for you! These types of slots will allow you to buy your way to the bonus game for around 60x to 100x your initial wager. 

You will recognize the bonus buy feature as a large button usually displayed on the side of the game, with the amount it costs to buy your way through.

The most popular bonus buy slots in America right now include:

Is There Such a Thing as a “Slot Strategy”?

Online slots 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 a few steps you can take before making a slots online real money wager that could increase your odds 

Your best bet is to look at the game’s RPT and volatility. These should be listed on the online casino directly. However if you cannot find it there, you can find this information from a simple Google search of the game. 

How do slot games work?

Slots come in different shapes and forms, but the basics for gameplay remain the same. 

  1. Place your wager amount per spin. You can set up auto-play for anywhere between 10 to 100 spins at a time.  
  2. Once the reels have stopped spinning, you will see a combination of symbols on one or more paylines. Depending on the combinations, you could be rewarded on the slot’s credit meter. 
  3. Your winnings will go into your account automatically while you play. Depending on the slot you have chosen, this could mean entering mini bonus games, or collecting free spins. 
  4. When you’re finished, you can choose to withdrawal or exit the game instantly. You will not lose your winnings if you leave the game.  

Now, every online slot will feature paylines, symbols, and reels. However, a lot of slots even go the extra step and add features like wild symbols, scatters, and bonus rounds, to make the game more fun for users.

Let’s take a look at what some of this stuff means:


These lines appear on the screen, showing a payout based on the winning combinations. Different slots games have different numbers of paylines which usually run from left to right.

In order to win, the player must match the symbols along an active pay line.


These symbols are found in slots games. They can be used in order to create winning combinations. Wilds come in different forms including:

  • Expanded wilds, which cover an entire reel.
  • Walking wilds that move around from reel to reel while the player spins.
  • Sticky wilds, which stay still and remain on the reels for a certain number of spins.


Normally, landing scatter symbols are what unlock the slots bonus game or it’s going to pay out a large amount of cash. You’ll need to hit at least a couple on the same payline, or it just acts as another normal symbol. 

Bonus Rounds 

Bonus rounds are an exciting feature offered by slots that allow players to increase their winnings substantially. You’ll need to land certain symbols on the payline (depending on the slot) to unlock the bonus game and then will usually get a select amount of free spins to use. 

Bonus rounds definitely have the potential to make you a lot of money, however, it isn’t guaranteed just because you have entered the bonus game. 

Play Free Slots Online at Your Favorite US Casino
