Try before you buy. It’s a request that customers from all walks of life have been after since the dawn of man. Online casinos understand this to a degree, and sometimes will offer welcome bonuses that include a no-deposit bonus. However, these bonuses are finite. Once you use them, they’re gone.

So often, what will happen then is that players will only get to play two or three out of what can be hundreds of slots that a casino has to offer. Then the question becomes do you stick with your favorite out of those two or three that you’ve played? Or do you keep trying new slots, now paying to try?

That used to be the big question. But now,you can play free slot games online without the need to download any software or register to an unfamiliar site. You can now try out hundreds of slots without spending a penny. Where? Right here at Gamble-USA.

A good strategy is to try each of these games to work out how difficult or easy it is to reach the free spins or bonus rounds before then looking at how profitable the bonus game is. All the credits are virtual. So if you run out of money, refresh the page, and your balance will automatically top back up.

Since these are free-to-play slots, you don’t even need to be located in one of the six states which allow online casinos. So if you’re planning a move, or if you think your state is about to legalize online casinos — you can now get a head start to learn all of the tips and tricks that there are for online slots.

10 Best Free Online Slot Machines No Registration or Deposit Needed

With hundreds of online slots available nationwide, it can be a tall order to narrow them down to a top 10. Though from our years of reviewing online casinos, we feel we have a pretty great idea of what users want. They want a variety of fun and exciting bonuses with good themes. A mixture of mechanics. And, of course, they want to get value for money — therefore, wanting to play online slots with good RTP. The below list and our top 10 best free online slot machines that you can play without registration or download right here.

#1 Raging Rhino

To start off this list, it’s the African savanna-themed Raging Rhino.

Raging Rhino

The six-reel four-row slot machine boasts 4,096 ways to win — and it certainly feels like it as Raging Rhino carries an RTP of 95.91% and a medium level of volatility. In the base game, you can expect a reasonably consistent hit rate providing a decent payout, though the only way to win big with Raging Rhino is through its bonus game. Collect between three and six of the featured diamond symbols to be awarded 8, 15, 20, or 50 free spins, respectively.

While Raging Rhino doesn’t provide the adrenaline-filled experience or the profitability of other machines, it is nevertheless a favorite among casual players looking to relax.

#2 Blood Suckers

Blood Suckers

A favorite of every veteran slot player. While the vampire-themed Blood Suckers may look unassuming on the surface, lying beneath the surface is one of the highest RTP games available in the US, with a mouth-watering 98% RTP.

In the base game, there are no fancy mechanics as the low-volatility 25 payline machine operates like many others. Though unlike a lot of other slots, Blood Suckers offers not one but two different bonus games. Either collect bonus symbols in each of the first three reels to go vampire hunting in the graveyards or collect at least three scatter symbols to activate the free spins bonus.

#3 Dead or Alive 2

Dead or Alive 2 is a personal favorite of mine. The Western-themed game is a slot that lives and breathes by its bonus features.

Collect three scatter symbols to have your choice of three bonus games where you can either play it safe with Train Heist, or risk it for that bid payday by going for High Noon Saloon. With three different bonus games, Dead or Alive 2 is a perfect example of why you would want to play for free before playing for real money so you can work out which bonus game you prefer.

Dead or Alive 2 bonus buy

Personally, I’m all about high risk and high rewards, so I go for the High Noon Saloon, where wild symbols are sticky, and for each additional wild that lands in a reel, all wilds in that reel get a multiplier.

No matter what you go for though, with an RTP of 96.82% and high volatility — Dead or Alive 2 bonus rounds always pay out massively.

#4 Ramses Revenge

With its cartoonish graphics, the ancient Egyptian-themed Ramses Revenge can look almost innocent at face value. But with its bonus buy feature, wherein you can buy directly into the bonus rounds, it has the potential to be one of the most exciting games.

Ramses Revenge

It can be triggered normally by getting two of the explorer symbols, though for x80 your bet you access it whenever you want. With only six free spins initially awarded, it can seem a steep price. Though with a mixture of roaming sticky wilds which can have the potential to gain unlimited multipliers and additional free spins, Ramses Revenge has the potential to deliver some serious payouts.

With a very high volatility and an RTP of 96.15% — Ramses Revenge is another game that really lives and breathes by its bonus rounds.

#5 Mercy of the Gods

Mercy of the Gods

Another game themed around ancient Egypt is Mercy of the Gods. With multiple types of bonuses, including a progressive jackpot mixed in with a high RTP of 96.64% — Mercy of the Gods is a great slot if you’re looking for something a little different. There’s a lot going on here, including multiple ways to win free spins and a jackpot mechanic which takes inspiration from the dragon link jackpot. Overall, what I love about Mercy of the Gods, is that with so much going on, it is not a game where you have to reach the bonus features to have fun, as just by getting a wild anywhere on the screen you’ll get free spins.

To describe Mercy of the Gods briefly is impossible. Instead, this is very much a game that you have to play to understand.

#6 Blood Suckers 2

With how successful its predecessor was, it was no real surprise that NetEnt doubled down by creating Blood Suckers 2. While RTP is slightly lower at 96.94%, the game is much the same. Again there are two types of bonus rounds achieved in very much the same way, though now, occasionally, your virtual companion Amilia will shoot from her crossbow a free bonus. This is because, unlike its predecessor, the big bucks are in the bonus rounds.

Blood Suckers 2

The most profitable one is triggered by getting the bonus symbol in the first three reels and involves the player searching for keys in chests. Find all the keys, and you’ll come away with at least x1,000 your bet.

Officially NetEnt lists this game as low volatility. However, from playing it extensively, I’d argue it plays more like a medium volatility slot.

#7 Medusa Megaways

While slots and ancient Greece tend to go hand in hand, it’s usually Zeus who finds himself in the limelight — though with Medusa Megaways, it’s Medusa herself who is the star. The base game has an RTP of 96.28%, though if you use the bonus buy feature exclusively, this increases to 97.63%. At x100, it can seem a risky play — though at the end of your bonus round, if things haven’t gone according to plan, you can choose to replay the feature once.

Medusa Megaways

I’m a massive fan of this feature as it gives the player a little bit of extra control over its high volatility slots bonus round feature.

The bonus game itself is one of streaks, as with each win, the multiplier will increase by one — and given that this is a megaways slot with cascading mechanics, this can lead to some massive wins towards the end of your bonus rounds. Medusa Megaways is another excellent example of why there’s a lot of value in playing the game for free first so you learn when to accept your winnings…

Medusa Megaways Big Win

and when you should tempt fate.

#8 White Rabbit Slot

The Alice in Wonderland themed White Rabbit slot produced by Big Time Gaming was the first slot to offer the option to buy the bonus feature. However, unlike a lot of others that followed, it included a feature wherein it could sometimes pay not to buy it right away. While technically, you can trigger it the normal way of collecting scatter symbols in reels 2, 3, and 4 — this is very difficult to achieve, so instead, players can collect the feature drop symbols to decrease the cost of purchasing the bonus feature.

This is a good idea as the base game itself, with medium volatility and an RTP of 97.24%, is plenty profitable by itself. The main draw of the bonus game is the cupcake symbol that expands individual reels.

White Rabbit Megaways

It can lead to some very unusual shapes, though given it’s a megaways slot, each additional reel just gives another way to win.

Another great slot that you should definitely play for free first so you can learn the optimal time to purchase the bonus rounds.

#9 88 Fortunes Megaways

With a high level of volatility and an RTP of only 96.06%, 88 Fortunes Megaways is a game that not everyone loves. Using both megaways and cascading mechanics, one of the chief complaints about it is that it rarely hits.

88 Fortunes Megaways

Of course, that means that when it does — it’s usually for a whole lot. There are a lot of features to 88 Fortunes Megaways, including free spins and their unique picker feature, wherein a player can gain free spins with a multiplier attached.

Overall, I’d be lying if I said this was a game that I love. However, many among our team do, and with the ability to play it for free — it’s definitely one that you should check out.

#10 Guns N’ Roses

What’s better than playing online slots? Playing online slots with Guns N’ Roses blasting through your speakers.

Guns n Roses slot

While a lot of slot machine developers might just use the Guns N’ Roses licensing to produce a mediocre machine with poor RTP — NetEnt isn’t like that, and with their Guns N’ Roses video slot machine, they offer a 96.98% RTP with medium to high volatility and a large assortment of bonus games unique to the rock star experience. My favorite is the solo multiplier which can award a multiplier of up to x10 to any winning line — taking your big win, to an absolutely massive payday.

If you’re a fan of Guns N’ Roses this machine is a must. Even if you’re not — with the fast pace and variety of unique bonus games, this is one that you have to simply try.

Instant Play Slot Machines vs Real Money Slots Online

So what’s better, free play slots, or real money slots? Well, like most questions in life, the answer is it depends. While free slots and free casino games can be a lot of fun — and can be great for strategizing, you’re never going to make any money with them. In contrast, real money games have countless stories of people winning life-changing money from them. But even when you’re not winning a fortune — real money games are just generally more exciting. Of course, with the chance to win money also comes the chance to lose money.

The good thing though, is that you don’t have to choose one or the other. There’s no reason why you can’t play free online slots today and then play real money slot games tomorrow. Chances are, if you’re reading this you’re at least somewhat interested in the idea of playing real money slots. So my advice to you is to play the slots listed on our site, and then go from there. If you find yourself tempted to play for some real money — you won’t even have to risk a penny initially, as a lot of US casino sites offer no-deposit bonuses simply for registering. This leads into our next section.

Play Online Slot Machines with a Casino Bonus

Playing online slot machines with a casino bonus is the best of both worlds. Get the chance to win big, while risking little or nothing at all.

Free slots no deposit

Take the DraftKings Casino welcome bonus as an example. Simply registering with DraftKings via our links will earn you a $50 no-deposit bonus. This is the perfect bridging step between free-play slot machines and real money slot machines as you’re still not spending anything — however, now you get to play for real money. Then if you decide that you love it, you can take advantage of their second bonus. A 100% first deposit match of up to $2,000. That means you get twice as much money to play online slots with for no additional cost.

And it’s not just DraftKings Casino, either. BetMGM Casino and Caesars Casino offer similar deals. If you want a different type of bonus you can try out Golden Nugget, who will match your first deposit dollar for dollar up to $1,000 plus 200 free spins of 88 Fortunes Megaways. Or, for something completely different, check out FanDuel Casino, where you can get a $100 free play and a $1,000 bonus.

The choice is yours. A no-deposit bonus, free spins — or have all potential losses covered. There are a lot of great ways to play either free online slots or real money slots.

Where to Play Free Casino Slot Games in the USA

There are a few options to play free slots online. Some of these options are state-restricted to NJ, PA, MI, DE, CT, and WV. However, there are plenty of ways to play free slots, even if you reside outside of those states.

Free Slot Games at Gamble-USA

If you’re brand new to slots, you’re in the right place. At Gamble-USA, we have an expert team dedicated to playing, reviewing, and bringing you the top tips for playing online slots. You can read our reviews for all the top slots available in the US, and then play those very same slots here. Available across the US, the only drawback to playing slots here is that as we’re not a casino, we do not offer the chance to play for real money.

What we do have though is deals with all the top US online casinos to bring you exclusive promotions and welcome bonuses so that when the time is right, you can make the transition from free play slots to real money slots seamlessly. So no matter whether it’s your first time playing online slots, or if you’re a veteran after a good deal — we’ve got something for you.

Legal Free Online Casino Slots

When it comes to online casinos, it’s not just real money play that’s available. At most of the top online casinos, you’ll have the option to play all of the machines on a demo mode. This is perfect for when you want to try a new slot machine without paying or if you want to check out any site-specific mechanics — plus, when you decide you want to play for real, you can try out their welcome bonuses, including any no-deposit bonuses that they may offer. Play free slots for real money.

The main drawback of playing free slots at a casino is that on many, you’ll have to register first. Plus, these sites are only allowed to offer their services to states where they have been licensed. So if you don’t live in a state where they’re licensed, you’re out of luck.

Social Casino Slots

Fortune Coins free slots

A lesser known option to play free slots is via social casinos. Sometimes referred to as sweepstakes casinos, these casinos get around many of the traditional laws concerning online gambling by offering their services under sweepstakes laws. According to these laws, any new sweepstakes online casino must offer a free-to-play service. Which they do, usually with their gold coin currency. These gold coins can be earned in various ways, including by simply logging in or registering.

As they operate under sweepstakes laws they’re typically available across the US so if you live outside of the states that allow online gambling, you can finally play online slots. These casinos can be a little tricky to understand. This is because if you want to transition to real money play, you’ll need to understand their dual currency system, which allows them to offer real money slots under the guise of sweepstakes. So if you’re interested, check out our reviews on two of the top social casinos: Fortune Coins and Pulsz Casino.

The main drawback of these sorts of casinos is that due to slot machine provider licensing agreements, you won’t always find the most well-known slots and instead must play their in-house designed slots which typically hide important data like volatility and RTP. Regardless, social casinos are a great place to play free slots with no deposit for cash prizes.

Guide to Playing Free Online Slots

Depending on the platform, there are a couple of different ways. The simplest way is, of course, via our website, where you can play free slots without the need to register or download any software. To play, simply select your desired slot and load it up. From there, you’ll be given a virtual currency that you can use to play slots with all the features of real money slots, including the ability to enter the bonus features and the chance to win free spins. If you run out of money, reload the page. Once you do, you’ll see that your machine is restocked with a full set of credits.

Playing free slots on either online casinos or online sweepstakes casinos is a little different. If you’ve ever registered for an online casino or sportsbook, you’ll probably know the drill. If not, the below guide will take you step-by-step through this process.

  • Using our secure links, navigate to your desired online casino. It’s essential that you use our links and enter our promo codes if requested, as only by doing that will you get access to the exclusive welcome bonuses.
  • Once you’re on the homepage, click “Register”.
  • Fill in all the required details, including your email and desired password. If you’re registering to a non-sweepstakes casino, you’ll also need to enter some personal information to verify your identity, including your full name, mobile number, and address. Once you’ve done that, click “Register”.
  • Now you’ll need to go to your email and click the registration link.
  • You’re done. Your next step will vary based on whether you are using a sweepstakes casino, a casino with a no-deposit bonus, or a casino that allows you to play demo slots.
    • If you’re playing on a sweepstakes casino, you’ll need to ensure that you have your gold coins currency selected. From there, you can select any slot and play it using the free currency.

How to play social casino slots

    • If you’re playing using a no-deposit bonus, the funds will be instantly deposited into your account. Just pick any slot, and play it using your free no-deposit funds.
    • If you’re playing on one of the casinos that allow for demo play, you’ll want to pick your desired slot and either click the “i” button, or the “Play Now” button. From there, you’ll get an option for either demo or to play with your cash balance. Select “Demo.”

Demo slot machines

    • That’s all there is to it. You can now play free online slots.

Is it Possible to Win Real Money When You Play Free Slots?

Generally speaking, no. Whether you’re playing here, at a sweepstakes casino with gold coins, or an online casino using their demo mode — nothing you win will have any monetary value. The only exception to this is with casinos that offer a free no-deposit bonus. With these bonuses, you’ll get funds credited into your account as soon as you complete your registration.

Though while these no-deposit bonuses are great, they are not unlimited. So even though you got them for free, you shouldn’t treat it like you would either the demo credits or gold coins at sweepstakes casinos. Instead, these free no-deposit bonuses should be used in the interim between when you’re looking to transition from free games to real money games.

Online Slots Basics: How they Work

If you’ve never played an online slot, you may be prone to information overload the first time you open one up. That’s normal and something that I experienced the first time I played online slots as well. So in this section, we’ll go over the basics of how online slots work, as well as some of the key terminology.

  • Coin Value & Coin Level —
    Slots coins
    These are two different features that both control how much you’re betting per spin. The coin value is simple. It’s the value of each individual bet. In the picture above, the value of each coin is 1.00. Level is a bit of an ambiguous term, and I prefer to explain it instead as coins per line, as it directly controls how many coins you’re playing per line. In the above example, we’re playing 1 coin per line. With Dead or Alive 2 having nine paylines, that means we are paying one coin for each of those nine lines, and with each coin having a value of $1 — the total value of each spin is therefore $9, as listed under in the “Bet Tab”.
  • Paylines aka Bet Lines —
    Slots paylines
    The goal of slots is to line up matching symbols. In what pattern you can match up symbols depends on the paylines. In Dead or Alive 2, the above are the nine ways your matching symbols can line up for you to get paid. These aren’t always relevant — as in Megaways, it doesn’t matter what pattern the symbols come in so long as there is at least one per reel. Occasionally games may offer you the chance to reduce the number of paylines played as a way to reduce your stake. Never do this, as it will always reduce RTP. Instead, if you want to reduce your total stake, either lower the coin value or the coin level.
  • Controls —
    Slots autoplay
    Autoplay allows you to play a certain amount of spins automatically without the need to click each time. By selecting it, you’ll be given an option to select how many spins you want to play at your current stake level. Max bet will take your current stake to the maximum allowed per machine. Typically you should ignore this option and instead manually select your bets so that you stay in control of your betting habits. Though do keep in mind that for jackpot slots, it’s common for a player to only be eligible for the entire jackpot if they’re using the max bet. Finally, the middle button is the spin button. By selecting it, you’ll do one manual spin.
  • Wilds — Wilds are a type of symbol that substitutes for all other symbols not including scatters. These symbols are able to substitute as different symbols for different paylines — or can even form their own winning combinations exclusively made of wilds for the biggest slots payout. As such, these symbols are among the most treasured.
  • RTP — Short for Return To Player, RTP is the defining metric of the profitability of any given slot. The number represents on average, how much of each stake will be returned to the player.
  • Volatility — While RTP determines the profitability in the short term, volatility controls it in the short term. The higher the volatility, the more prominent the deviation will be from expected average return per spin. Typically the higher the volatility, the less frequent wins will come — with the caveat that when they do come, they’ll typically be a lot higher than a low volatility game.
  • Bonus Rounds & Scatter Symbols — While the base game can be plenty profitable, in most slots the real money is to be made in the bonus rounds which are triggered by scatter symbols. Unlike traditional symbols that need to match up from left to right in specific patterns to get paid, scatters just need to land anywhere on the reels — and when three do, the bonus rounds will trigger. What these bonus rounds will be will depend on the game. The most common, however is free spins. To check the details of the bonus feature on your slot machine, click the “i” button, and navigate to the relevant section.

Free Slots Bonus Games

For many machines, the promise of jackpots will lie in their bonus games. But talk to anyone experienced in slots, and they’ll tell you how hard and costly they can be to reach. And of course, the worst feeling is when you reach it — and it’s a miserable bonus. That’s why when scoping out a new slot — it’s always best to try them for free.

Book of Dead Bonus

By doing this, you’ll get a good idea of how difficult they are to trigger, and how profitable they can be. A great example of this would be Dead or Alive 2, which takes about 70 spins to reach its bonus round selection stage, where it gives you the option to pick from three bonus games. By trying it out for free first, you can try all of the bonus games to see which one you prefer before playing them for real money if you desire.

Multipliers, feature drops, free spins, additional reels, upgraded symbols, lucky wheels, pick me bonuses, and anything else goes with top slots bonus rounds.
