Best Online Slots You Can Play for Free in 2023

Last Updated: 20/09/2023

In all land-based casinos, you can only play slots for real money. There are no free-play versions at all. Most of the best online casinos, however, offer hundreds of free slot games to try out. 

Some casinos offer Free Play credits, which are essentially a limited number of credits that you can use to play slots for free. When the credits are finished, so is your Free Play session. This is a bit old-school, though. Most modern casinos offer most of their slot games in demo mode, which are preloaded with virtual credits. These credits will reset every time you start a new session, so they are not limited. 

Neither of these options gives you the opportunity to win actual cash, but the game mechanics and bonus features are the same as the real money slots. In a nutshell, demo slots give you an accurate idea of what the real money version would be like – minus, of course, the element of risk and the associated adrenaline rush.

How to Play Free Slots Online

It's easy to play free slot machine games without downloading or registering. All you need to do is browse our extensive collection at the top of this page. You can filter the games and sort the list by RTP rates or sort them from newest to oldest. Filter by Progressive to find the games that have proper jackpots. Of course, you can't win the actual jackpots without playing for real money, but it's always interesting to give them a test run to see how they work.

Alternatively, if you want to play free casino games at a slot site in your area, just choose one of our recommended casinos and sign up. The process is usually fairly straightforward once you verify your address and identity, and you can be playing great slot games in minutes. The beauty of this approach is that you can test the casino site, check out all the games available, and you can switch to playing real money slots by simply making a deposit. Then you can have a go at winning those progressive jackpots.

Step 1: Select an online casino

Choose a casino from our recommendations on this site. It's important to go for a casino that's legal where you live to ensure it is regulated, licensed, and safe. Don’t make the mistake of playing at an illegal, offshore online slots site that doesn’t have the same safeguards or assurances.

Step 2: Create a username and password

The registration process at most casinos is quick and painless. Create a unique username and enter information such as your name and address. You may have to provide the last four digits of your Social Security number and other identifying information.

Step 3: Find the slots lobby

Before you play real money online slots, you may have to upload a scan of your passport or driver's license. However, you can normally start playing free slot games right away. Depending on the casino's user-experience level, you should be able to filter the games by the slot theme, game provider, or game type. At some casinos, you can add slots to your “Favorites” list for easy access later.

Step 4: Playing the games

Find a slot game you like and click the “Demo Play” button, if available. The slot will load instantly in your web browser. Most free slot games are powered by HTML5, so your gameplay should be smooth, and the game should adapt to suit your device, whether you play on mobile or desktop. 

Free Spins

Free Slots vs Free Spins

One thing to be aware of is the difference between free slots and free spins. Free spins are bonus stakes handed out by a casino that does not dip into your real money bankroll. You’ll typically find them offered as part of a casino welcome bonus or reload reward. Free spins usually have a pre-set value on a pre-selected game and are a way of playing real money slots for free.

The term "free spins" is also used when referring to a slot’s mechanics. Many fan favorites will contain a bonus round or a free spins round, where you win in-game spins that don’t require an additional stake. This freebie is an excellent addition to your gameplay, but you won’t receive them anywhere except within the game itself.

On the other hand, free slots are demo games you can play that don’t offer real money rewards. Every spin in a free slot game is considered a free spin since you’re not using real money to wager with. Yet, when we refer to free slots, we are referring to these free demo replicas of real money games, which allow you to learn about the gameplay and how to win on slots.


The Different Types of Free Slots

Most casinos offer demo versions of all their slots. Simply select the Practice Play or Demo Play tab in the lobby to load up free slot machine games.
