What Are Online Slots?
Online slot games are played similarly to land-based titles. The game features a set of reels you spin with paylines attached. Land a matching symbol combination, and you win a prize or trigger a special feature. Slots are the easiest games to play at an online casino and can award players large prizes.
High-RTP slots offer a better return on your wager on average, while high-volatility slots may produce big wins.
Real Money Slots vs Sweepstakes Slots
Casino slots real-money wagering means playing with actual cash. It requires you to deposit money to play.
Meanwhile, sweepstakes slots don’t require users to spend any money to play. Sweepstakes slots use Gold Coins (GC) for free play. These have no value and are just for fun. These casinos also use Sweeps Coins (SC), which also have no inherent value, but can be redeemed for cash prizes in some cases.
Why Play Slots for Real Money?
The best reason to play slots for real money is for fun. It’s a good idea to set a budget so you know how much you can spend on your hobby.
Playing real-money slots doesn’t guarantee any chance of winning money back. However, you can take advantage of offers like slots with free spins to potentially win money without depositing any extra cash.
How Do Online Slots Work?
Slots are often based on popular themes and features, such as fantasy settings, historical periods, or certain cultures. However, they all work similarly. Slots have certain elements that create the base configuration of the title. I’ll cover these elements below to help you understand how games work and what to expect.
Paylines
Every slot game has a set of paylines. To trigger a prize, you must land a matching symbol combination on an active payline. Some games offer a set number of active paylines, while others allow you to select how many are in play.
Paylines can appear in a game in a horizontal or diagonal placement. As well as zigzag or odd patterns. Each game will showcase the number of paylines on the game grid.
Wild & Scatter Symbols
The most common symbols seen on slot reels are the wild and scatter symbols. Generally, a wild will substitute for other icons in the game to help create winning combinations.
Wilds only sometimes substitute for scatters, but can do so, depending on the game. Wilds can also offer multipliers to boost prize potential or other incentives, such as walking across the reels or expanding.
Scatters are usually attached to bonus features of the game, such as free spins. You need a certain number of scatters to trigger the free spin round. The number of spins you trigger is generally associated with the number of scatters that activate the round.
The scatter icon can also provide access to payouts. Some slots offer prizes for a set of scatters plus free spins and even multipliers from time to time.
Bonus Rounds & Free Spins
As mentioned, free spins are often an element found in games. The feature is generally connected to a scatter, but can also be part of a bonus round. Special bonus symbols will trigger additional elements in a slot game, like free spins or a pick’em round.
Software developers often add bonus rounds with a secondary screen to change up the visuals of a slot game. You may see a pop-up or a new screen on the reels where you play the bonus game.
Some slots offer bonus rounds with a pick feature where you make selections. Each selection can help you win a jackpot prize, free spins, or a multiplier. The incentives provided by a bonus round will vary based on the individual game.
Progressive Jackpots
A progressive game is one of the most popular online slot game types available today. This type of slot offers a special jackpot that players can trigger. A progressive jackpot can be fixed or rolling.
With a fixed jackpot, the player can win a prize that remains the same. This prize is based on a multiplier. The prize could be 2,500x the bet or higher. You can win the prize if you trigger the jackpot based on the game rules. The trigger could be a certain symbol combination or based on a bonus round.
With a rolling progressive, players will find the jackpot continues to grow until it is activated. A small portion of each bet goes towards the prize. This progressive type is usually triggered at random or with a bonus round.
Online slots casino games come in all shapes and sizes, but my fundamental rule is to find a slot that you’re confident you understand. This is one reason I love classic slots: the old-style fruit machines that have very few added features. While they may not come with such great prizes as more advanced slots, they’re my favorite free slots to play at sweeps casinos, and I still play them at regular online casinos.
What Is Return-to-Player?
Return to Player or RTP describes the percentage of prizes that will be returned to the player based on the amount of funds played. It sounds confusing, but it is generally easy to understand if you remember that a higher percentage will typically give you a better return.
Let’s say a game has a 97% RTP. If you play $100, you should expect to see a return of $97. Playing games with a higher RTP helps to increase your return potential.
Of course, the house always has the advantage. That’s how it works! But high-RTP slots are a great choice if you need to meet a casino’s wagering requirements to redeem bonus funds, such as a 25 free spins no-deposit offer.
I’ll cover RTP more extensively below, so you can learn how to use this element to your advantage.
What Is a Random Number Generator?
To create a fair gaming experience, slot games include a random number generator (RNG). Software developers must use quality random number generators to ensure that the outcome of every spin is fair and random.
The RNG consistently generates numbers at a fraction of a second to input the outcome of a game. Random numbers determine the win or loss from each spin. Slot games are a gamble because the RNG makes the outcome completely random.
It also protects the integrity of slot games because the casino or software developer doesn’t control the outcome. Online casinos must test their software regularly to ensure that RNG and other elements operate correctly for a secure and fair gaming environment.
Types of Online Slots
Online casinos offer a wide range of slot games for players to enjoy. It’s easy to find a game you like when hundreds of titles are offered on one platform. Software developers focus on making quality games for players of various types, including 3-reel, progressives, video slots, etc. Read on to find out more about the types of online slots you will come across, to decide which game type will suit you best.
Progressive Slots
Progressive slots are one of the most popular online game types available today. Players can enjoy quality reel spinning with a chance to trigger an extra prize with the progressive. Some games have just one additional jackpot, while others can offer four or five extra prizes.
Fixed progressives offer a set prize based on your bet amount. Rolling progressives will continue to grow until activated. These prizes can reach massive heights, with some players winning seven figures or more!
Divine Fortune is an example of a popular progressive played in the United States online. This is an older slot game with a mythological theme. It is often featured at most online casinos in the US and is known for offering major jackpot prizes. If I have a chance to play slots with free spins, I’ll usually try out a progressive jackpot slot.
3-Reel Slots
This type of online slot game has just three reels and is generally based on a classic, Las Vegas-style theme. Titles will offer diamonds on the reels along with fruits, 7s, bar icons, bells, and dollar signs.
3-reel slots don’t come with any bells and whistles. The game usually just offers payouts for a three-of-a-kind symbol match. You might come across a wild or jackpot prize, but free spins and bonus rounds are rare with this game type.
Double Diamond is an example of a 3-reel game that is popular among online gamers. Created by IGT, this 3-reel title offers a max payout of $100,000 and includes a classic reel-spinning experience.
Video Slots
In this category, players have access to quality gaming options. Video slots fit the genre of games with five or six reels that include features like free spins, bonus rounds, and wilds.
Video slots include quality graphics and animations with fun themes that entice players to keep spinning the reels. You’ll find games that offer Egyptian or Wild West themes, Greek Mythology, and Roman Times, among many other options. Video clips or animations make the gaming experience much more interesting and fun for the player.
Mercy of the Gods is a good example of a successful video slot. This game features an adventure theme with an Egyptian twist. The game includes three jackpot prizes plus many special features to explore.
Megaways
One of the most popular slot types you’ll find at online casinos in the US is Megaways titles. This type of game features a Megaways mechanic. Instead of offering traditional paylines, this game will include several ways to win a prize. Most games start at around 50 megaways or higher, and as you play, you can hit up to 100,000 or more ways to win.
Each Megaways game plays differently. Most require you to hit certain symbol combinations or activate features to trigger the full mechanic. Once you do, this activates even more ways to win, and prize money can reach astronomical heights.
An example of this game type is Atlantis Megaways. The slot has an underwater theme based on the lost city of Atlantis. Spin the reels and explore the underwater realm with up to 117,649 ways to win. The slot includes four jackpot prizes, with the top one offering 2,000x the bet.
Megaways slots are extremely popular, although they can be a little overwhelming for beginners. I recommend starting on simple slots, learning how the basic mechanics work, and then you can progress to slots with more features and bonuses once you’re confident!

The RTP for this game is 96.18% and includes five reels with 40 paylines.
The best real cash slots depend on what you’re looking for in a game. I try not to overcomplicate things: if I’m having fun playing a slot, then I know it’s a good game! If you’re new to slots, I recommend trying out free sweepstakes casinos first to get a feel for the types of games you enjoy.
How to Choose the Best Online Slots
Choosing the best online slots will create a more enjoyable experience and increase your win potential. Below, I’ve listed a few tips on how to find quality games for your reel-spinning sessions.
Strong RTP
Not all slot games have the same RTP. Each software developer will list the RTP of a game within its info section. Before playing a game for real money, look at the RTP information. Play games that have a strong RTP of 96% or higher. Lower percentages only decrease your win potential. With higher percentages, you can see a better return on your investment.
Free Spins
Another great tip is to look for games with free spins, such as a 25 free spins no-deposit offer. You can trigger free spin rounds with scatter icons as you play. The feature allows you to play at no cost but still get wins. This helps to lower the amount you spend as you play.
Bonus Rounds
Look for games that feature bonus rounds for an added element during gameplay. Bonus rounds can include pick’em options where you select items for instant prizes or free spins. You can also access bonus rounds that can produce jackpot prizes for even more win potential.
Easy to Play
If you’re a beginner, look for slots that are easy to play. I suggest games with three reels for starters. This helps you to know how a slot game works before moving on to larger reel games like video slots.
Game Type
It’s also a good idea to think about the game type. Suppose you want a more involved game; select Megaways, video slots, or progressives. These games will offer multiple features and include various ways to win.
The best slots online depend on the person playing them. Consider free spins offers or sweepstakes casinos if you’re looking to try something new, and then, when you’ve found a game you love, consider online casino slots real-money wagers.
How to Win Real Money Playing Slots Online
There is no guaranteed way to win real money while you play slots online. However, there are some strategies you can employ to boost your odds.
I suggest you look at the RTP of an online slot game and select titles that have a 96% or higher. This helps to increase your return on investment potential. 96% is average, while 97% or above is a very strong RTP.
Real Cash Slots with Promotions & Bonuses
You can also utilize welcome offers to increase your bankroll with bonus cash. Many sites offer a deposit match or a no-deposit offer you can use for slot play. The maximum bet can also increase your win potential, especially with progressives, but I’d be careful with this: don’t add more money than you want to.
Remember that at the end of the day, online slot games are based on luck and will randomly award wins to players. Enjoy playing slots for fun; remember, it’s about entertainment value and having a good time.
Online Gambling Slots and Responsible Gaming
Many platforms have self-exclusion options for gamers or provide contact details for helplines if you think you’re playing too much. I highly recommend reviewing a platform’s self-exclusion policies before signing up if you think an opt-out would be useful.
In my book, it’s also a good look for a casino to provide support to its players. Sweepstakes casinos can be another great alternative if you want to avoid playing with real money!
Best Online Slots with Real Money Games: Verdict
The best real-money slots are characterized by offering a wide range of slot options, such as progressive jackpots, classic slots, and video slots. There should be both volatile and high-RTP slots available so that gamers of all tastes can have a great time.
Welcome bonuses like free spins are what help the best online slot casinos stand out from the crowd, as well as bonuses for existing users. My top pick for real-money slots in the US is BetMGM casino, as it offers a huge range of slots as well as a strong sign-up bonus.
I’d recommend that newer players consider learning about slots by playing sweepstakes casinos before moving to real-money gaming. Top sweepstakes casinos offer the same slots as their real-money counterparts, but you can play with free Gold Coins before you try them for real.
The best slot game is one you enjoy. Find your favorite from our recommended casinos, and as always, happy gaming!
