Free Online Slot Games in the US 2024

There is not one specific site to play the best free slots. In fact the whole point of demo play is to see what games are offered at different brands before ultimately deciding which site you want to play at for real. New games are frequently added to the game lobby, older games get revamped to keep things fresh, so it helps to be able to try out a slot for free when you want to.

If you’re looking for free online slots, it’s best that you explore various sites. When you load up free slots online, the house will give you play credits to use. If you run out, simply refresh the page or try another game. But if you need some inspiration, I can highly recommend these five sites:

You can play slots online free of charge wherever you are, as you aren’t using with real funds. If you do want to make that switch, you must be physically located in West Virginia, New Jersey, Michigan, Connecticut, Pennsylvania or Delaware. 

On this page, I’ve listed sites that offer free online slots on top of their regular way of playing.

To get started, you usually have to register an account which takes a few minutes, but once you’re done, you have access to the entire slot library including the latest free online video slots from the biggest developers. You can also try out any slot you find here without paying anything!

The game mechanics in free online slot games are identical to the real deal, the only difference is you can’t win real cash. However, they are great for learning the rules, testing the volatility or seeing what a bonus round is like. 

Free slots websites

If you’re looking specifically for sites that offer slots for free, trying out a Social casino could be another option. These don’t work like regular sites where you make a deposit to start playing. Instead, you play with virtual currencies credited at the casino.

The beauty of free online slots is that you can try out slot games with no risk. They also give you a good impression of the game developer and sometimes the gaming site. You can play around and find online slots that best suit your preferences.

By visiting the casino game lobby and picking a game, you can most of the time start playing free casino slot games for fun with no download. Often, there’s no need to register an account: just open a slot game and give it a spin!

With so much choice available, it’s important you pick the right online casinos to spend your money on. That’s another reason free online slots are so beneficial. Although you can’t technically win money on game demos, you can find a theme you love and decide which slot features you like the most - and there's a lot to choose from!

Most of these US sites offer a Favorites-service in their lobby. Choose the free games you love and add them to your list for easy access.

By playing free slots online, you can get a feel for what kind of bonus rounds and features you can trigger in each game, and how. Without having to spend a cent, you can continue spinning on a chosen slot until you reach a bonus round, explore what it offers in terms of excitement and entertainment, see if it measures up to other games you’ve tried and after that decide if you want to play for real somewhere with a casino bonus.

The bonus rounds are activated during game play, so just hit “spin” on the free version until the feature is triggered. Here are some of the most popular free slots with bonus features and free spins:

• Jungle Spirit: Call of the Wild – this slot lets you pick a figure that gives you a set amount of bonus spins. It also includes 243 bet ways that can expand to 1024, as well as multipliers that can increase your wins with up to 30 times.
• Jumanji – another favorite from NetEnt that brings back some of the magic from the movies based on a board game. With a max win of 140x your stake, sticky symbols, re-spins and wild features that can take over entire reels, there’s plenty of bonuses and free spins to claim, especially if you try it for free. The graphics won’t disappoint you either.
• Big Bass Bonanza – if you try this free online slot from Pragmatic Play, you’ll eventually get to the bonus round where you get bonus spins. The fun part with this bonus feature is that it can be retriggered, and with added multipliers if you’re lucky. 
• Book of Dead – one of Play’n GO’s top slots with free spins you can play for fun. It also features expanding symbols to help you win more during the games bonus feature. 

You can play hundreds of free mobile slots on your smartphone or tablet. The good news is that nowadays, the free games at mobile casinos are the exact same as on desktop if you play on a modern website, as everything is adapted to the smaller screens.

The only difference is you make decisions by swiping the reels or tapping the game buttons. Some of the layout and graphics may be different but the bonuses and payouts will be identical.

To play free slot games on your smartphone, you may need to download an app, although this depends on how mobile friendly the website is. Some sites also let you install individual free slots directly to your device.

You do however find most free slot machine games without downloading or registration of any kind. Just open and load up a game instantly in your browser.

Some casinos let you test their slots for free, sometimes without registering an account. Confirming that you are over 21 and then loading up a free game in your browser could be enough. However, most times you'll need an account even if you just want to try out a slot before you spend money on it - which you should!

It's a simple process though, and usually doesn't take more than a few minutes:

1. Create a username and password - Fill in a username and a password you will remember. Make sure your password is unique and hard to guess. Then fill in the required information like name, DOB, address, email and Social Security Number.
2. Verify your email - Click on the activation email to complete the account setup. The casino will also do a check that your SSN and home address are valid.
3. Start playing - Log in and head for the slots section. Most sites let you try them out for free, so there is no need to visit the cashier first.

So you’re new to online slots and want to play some demos before signing up. But which slots should you play if you’re a beginner? Most casinos offer demo versions of all their types of slots. Simply select the Practice Play or Demo Play tab in the lobby to load up free slot machine games.

3-Reel Slots

3-reel video slots resemble the classic games you’ll find in your local casino. 3-reel slots feature a handful of paylines and nostalgic symbols like melons and bells. These classic slots also tend to lack complex bonus features.

5-Reel Slots

The majority of online slots today have 5 reels. With 5 reels, it’s possible to fit more paylines into the game. It also allows the developer to cram in as many bonus features as they like. The number of available paylines in a 5-reel slot can vary, but it’s common to see anything from 9-99 win lines. Some modern 5-reel slots have expandable reels that can accommodate thousands of win ways.

Progressive Slots

In a progressive slot, a portion of every qualifying bet contributes to a giant jackpot. You can trigger the jackpot by playing a special bonus game. Some progressives, however, are awarded totally at random. You can definitely try out a progressive free slot game. You won’t be able to win the jackpot, but you can get a feel for the mechanics.

Branded Slots

Branded slots are usually produced in partnership with film or media companies. They might be based on the career of a musical group or themed around a hit Hollywood movie. Branded games usually feature authentic video and audio footage – perfect for fans.

Video Slots

The original land-based video slots used computer chips and video screens to display the action. Now, all online slots are video slots. The best video slots on the market use crystal clear computer graphics and random number generators to determine the action.

3D Slots

The advance of technology has made slots more immersive and fun to play. The latest 3D slots boast amazing animation and slick graphics to draw in the player. They often have innovative bonus features that make full use of the reels and symbols.

Megaways Slots

Megaways slots are hugely popular and widely available at legal online casinos in the US. In a Megaways slot, the number of paylines varies from spin to spin. In a Megaways slot by BTG, for example, you can cram in as many as 117,000+ win lines on your spin.

You should only play free games and slots at legal, trustworthy casinos. All sites I recommend here are licensed to operate in their respective states. Plus, slot providers must acquire gaming licenses in order to supply games.

When you play free online slots at a regulated casino, you know that every game is legit. The payouts and random number generators have been independently verified. The best casinos even display test certificates on their sites.

As playing slots online free of charge is legal and fair, you won’t have a problem when it comes to risking your own money on real-cash games.

Free Slot Random Number Generator

Whenever you play online free slots, the gameplay is governed by a random number generator (RNG). As soon as you tap the Spin button, the RNG calculates an algorithm which determines where the reels stop.

Every algorithm produces a number that relates to a position on every reel. The process is entirely random and there’s no way of predicting where the reels will stop. RNGs are carefully audited. Licensing bodies employ testing labs which regularly test RNGs to ensure complete fairness.

Testing bodies put RNGs through a rigorous process. They are tested over millions of spins to make sure there are no irregularities. The lab will also have pass or fail limits on which the RNG is judged.

I only highlight the very best legal sites and offerings and my testing criteria is solid. So except for the varying features and aspects of different games, you can expect the following when you pick a site you find here:

• A Wide Range of Free Slots - All my recommended sites come with a broad selection of online slots you can play for free. Choose between classic 3-reel classics or the latest 3D slots full of features from both new and established developers.
• Fair Online Gaming - Regulated casinos provide a safe haven for gamblers. You will only get access to fair free online slots that have gone through rigorous testing. Plus, all sites I recommend are licensed and regularly audited to make sure the random number generators are fair and reliable.
• Fast and Reliable Payments - It’s great to play free slots, but eventually you might want to deposit some cash for a chance to cash out. Having several payment methods to choose from is ideal, and you want withdrawals to be swift and secure.
• Great Bonuses Every Time - You can also earn money by playing free casino slots. Some sites offer a free spin bonus on the latest games, for example a 200 free spins no deposit bonus. Just remember to check out T&Cs for any offer you claim so you know what’s expected!
