Playing Slots Online for Free vs. Real Money
Slots can be some of the simplest games you can play at an online casino—they can also be some of the most complicated. Before you wager real money on an online slot, it’s a good idea to play a few rounds for free.
If you’re learning how to play slots, you’ll notice the online games aren’t the same as they are in a brick-and-mortar casino. First, the number of slot games will astound you. Second, many software developers design their slots to be more engaging, with immersive graphics and sound effects. Third, there are tons of multi-payline slots and slots with progressive jackpots, too. There’s a lot to learn.
Playing for free means you won’t take home a big jackpot. Instead, you’ll gain an understanding of how the game mechanics work, what symbols to watch for, and what the bonus rounds offer.
You can find free casino slots on just about any casino website. You can usually play a few demo rounds on the software developers’ websites, too.

Types Of Real Money Slots
Due to their global appeal and huge fan following, many slot machine types exist. Read the guide to slots terms below to help you select the perfect slot machine for you.
How do Slot Machines Work?
Slots online work in a similar way to the sophisticated slot machine games on the casino floor. Each one is designed by top developers to be fun, of course. But more importantly, they’re designed to be completely random. This is due to the RNG or Random Number Generator.
An RNG is a complicated algorithm written into the game software. It ensures that each spin is completely random. This means the games are always fair.
Leading Slot Machine Providers
If you’ve ever played a slot machine, there’s a strong chance that one of the companies listed below was responsible for making it. Some of these companies power slots for online and in-person casinos while others focus solely on the internet market.
These slots are designed and released by Betsoft Gaming Ltd., an online casino software developer based in London. Best known for their line of innovative 3D slots, this company is often cited as being on the cutting edge of the video slot industry.
Founded in 1998 and including clients such as Sportsbook, this online casino company is known for its progressive slots, many of which are connected across all casinos powered by RTG.
Rival slots, as well as other casino games from this online software provider, made their debut in April 2006. While the selection was limited to begin with, the company has since grown to offer over 160 games for both desktop and mobile gamblers.
Founded in 2014, Platipus Gaming is as UK companies with the latest HTML5 slots and table games. Platipus Gaming's slots are eye-catching and imaginative, and they have fun themes you won't see everywhere. Try Little Witchy, Post Cats, or Un Dia De Muertos.
Nucleus Gaming is a newer provider with a growing list of 3D cinematic games. Nucleus Gaming features 110 slots at the moment, which are optimized for mobile devices. When you play at a Nucleus Gaming site like Sportsbook, all of the Nucleus slots are available for Android and iPhone devices.
Dragon Gaming started in 2004 and provides slots in 25+ languages and 25+ currencies. Dragon Gaming is known for fun themes and excellent graphics. Rise of the Titans is a player favorite, while Basketball Legends, The Wicked Witches, and The Defenders are newer titles.

What Are The Best Online Slot Bonuses?
Luckily for slot players, casino sites favor them with the biggest bonuses in the market. Players therefore receive the best online slots bonuses when they make a first deposit. Even on reload bonuses, slot players receive the biggest offers.
Even better, casinos stipulate that slots clear the wagering requirement with a 100% the contribution rate. Here's a quick look at the best slots bonuses you'll find online.
Most of the time, these are the biggest bonuses you'll find at an online slots casino. These match the amount of your initial deposit, though some gaming sites offer match bonuses on the first five to 10 deposits. The match percentage tends to be 100% or higher, often with rates as high as 200% or 300%.
Free Spin Bonus
Often, casino sites attach a free spin bonus to the traditional welcome bonus. At other times, these are stand-alone free spin offers or free bonus chips. Players find these less confusing, because you keep the cash from the bonus spins and don't worry as much about match rates.
Similar to the welcome bonus, this offer applies to continuing or loyal customers. While the match percentage usually isn't as high as a welcome bonus, it's often redeemable many times over – as much as five times per day in some casinos. This makes it potentially more lucrative.
Slot Of The Month Offers
Many slots casinos feature their newest slot games or most popular online slots with a "Slot of the Month" offer. This either provides double or triple the comp points from playing the slot or a certain number of free spins on the slots game.
A catch-all term that might apply to welcome bonuses, reload bonuses or weekly bonuses. Essentially, it matches the size of the deposit you make. Remember that match bonuses have a wagering requirement or rollover before you can withdraw your winnings.
Mobile Slots Apps
The US online casinos that we recommend have seamless compatibility with mobile slots. In most cases, you won't need to download a mobile slots app. Instead, navigate to the site using your Android smartphone or tablet, iPhone, or iPad and click on the game icon. The slot game should open in your mobile device.
Basic Slots Strategy
It’s a bit silly to think about strategy and slot machines. After all, slot machines are as random as they come. While some slots might give you a bit of an edge if you’re making maximum bets, there’s no such thing as a hot slot machine. It simply doesn’t exist. That said, there are a few strategies you can use to help get the most out of your gameplay and extend your bankroll.
Online Slots FAQ
Can you win money playing online slots?
Yes, but it's not a certain thing. Don't make online slots betting your profession. Online slots have a house edge, so you can expect to lose money over time.
Treat slots online as a form of entertainment and the house edge as the price of entertainment. Unlike most forms of entertainment, though, you get lucky and win sometimes.
What are the best online real money slots?
It depends on your preferences. Some players want to play progressive slots with huge jackpots, which give them a chance to win life-changing payouts. Others prefer fixed jackpot slots that give them a chance at more attainable or realistic payouts.
Still others love fun themes, 3D graphics, lots of cool bonus features or licensed games involving their favorite pop culture franchises. The great thing about slots is the sheer number of great games. Pick one and start playing real money slots today.
Is it safe to play free slots online?
Absolutely. You can play at a real money online slots casino without ever making a deposit or risking your hard-earned cash. When you click on a game icon, choose "Practice" as the play option. The graphics and game controls are the same, but you'll be playing free online slots instead.
Can I play online slots for real money from the USA?
Yes. US residents in all 50 states can play online slots for real money. Only 5 US states have licensed and regulated online casinos. The remaining states don't regulate slots casinos online, but they also don't prosecute residents who play online. Instead, slot players play at offshore online casinos.
The bulk of these sites are safe and trustworthy – most are licensed by foreign regulators – but Americans won't play with consumer protections. It's important you choose reputable slots casinos online, so read our casino reviews before playing slots online for real money.
What is the secret to winning the jackpot on slot machines?
There is no rock-solid secret to winning online slot jackpots. Slots are games of pure chance. The random number generator (RNG) produces thousands of results per second. When you click "Spin", the RNG gives you the latest result.
No one can predict the RNG's results; anyone who tells you otherwise is a scam artist. Enjoy playing slot machines, but have a bankroll and never depend on winning at the slots.
What is the best online slot machine?
That depends on your preferences. Many players like progressive slots the most, because they offer life-changing jackpots. Mega Moolah is the progressive slot with the biggest jackpots (on average), while RTP slots like Megasaur and Jackpot Cleopatra's Gold have the biggest prizes in the US market.
Some players prefer 3-reel classics, because they have smaller, more attainable prizes. Others prefer online slots with lots of features to keep things interesting. Even more prefer licensed slots, which have soundbites, music, and video clips from players' favorite pop culture franchises.
What are the safest online slots?
The safest online slots are those at the safest online casinos. Read casino reviews, which assure you'll deposit your hard-earned money into honest casinos with world-class encryption, fair games, and fast payouts.
