Play Free Slot Games - Free Demo Slots

If this is your first time on SlotsCalendar and you don’t know what to expect, you should know that we never half-a$$ anything.

We started this affiliate website because we were a bunch of players who couldn’t find accurate and complete information. It was a hassle to find amazing games, get the latest promotions and stay up to date on the latest online gambling industry news.

So we went all out and decided to become the source of all the things about for other players. So, of course, we will go all out for you every single time. We’ve divided everything into neat little categories so that you’ll have an easier time finding exactly what you came here for.

Switch Between Sub-Categories 

When it comes to free online slots, you will see that from this main category, you may divide the games into sub-categories:

• All games (including table games, if you want to try something else like scratchcards, Slingo, roulette, video poker or blackjack)
• Video slots
• Jackpot slots
• Mobile slots
• Classic Slots
• Fruit Slots

Each category will provide insight into that particular type of slot game or casino game, so if you don’t know what to expect or how to play that particular game, you will learn. We also have helpful tips and tricks, frequently asked questions and more to help you on your journey to becoming the greatest player.

How to Use the Search Function

These sub-categories are here to help you filter and find a game when you don’t know what popular demo slots to try, but if you know exactly what you want to play and already have your favourite free slot machines, you may use the search function.

On the upper right side, no matter where on our website you are, you will see a magnifying glass. That’s the search button, and it will allow you to search through the entire website and show you both exact matches to your query as well as partial matches.

This means that if you search for Starburst, for example, you will get all the Starburst demo slots (classic, Xxxtreme, Slingo) but also games that are similar. You will also see all the bonuses currently available on this slot game, casinos offering it, the game’s software provider (NetEnt), and a couple of blog posts or news related to it.

Learn How to Use the (Slots)Calendar

In case you haven’t noticed yet, the name of our website isn’t SlotsCalendar for no reason. The whole point is that our main feature is a calendar of slots. Right on the homepage, you will see a calendar, and if you click on it, it will show you all the free slots that have been released in the past month (and year and as far back as you want).

You may also look into the future and see what demo slots will be released in the months to come. You have the option to mark unreleased free slots UK and get notified when they are live and play them for real money and great online casinos.

We try our best to ensure that we have the latest free online slots available for you in demo mode so that you’re always the first to try them. All new free online casino slot games are here so that you won’t miss out on great opportunities.

Are Free Slots Legal?

The United Kingdom is the most regulated market in the online gambling industry, thanks to the rules of the UK Gambling Commission. While in most jurisdictions, you may play free slots if you are over 18 years old and you just have to tick a little box to confirm your age, the UKGC takes extra steps in prevention.

Free slot games are available to UK players, but they must sign up for an account and log in whenever they want to try games in demo mode. What is more, there are a couple of free demo slots that are just off the table for British players.

But all in all, free slots no download are legal in the UK, assuming that the casino software provider that created the game is a reputable one that has a UK license or at least a license from another online gambling entity that’s related to the UKGC (like Gibraltar or Isle of Man, for example).

Free Slot Machines Available Only to Players from Certain Countries

If you’ve been trying to play free casino slot games on our website and some wouldn’t load, it’s because there are restrictions based on your location. Some slot games or other types of casino games are only available to players from specific countries. Primarily because of the reason we explained above (licensing), but also because some software providers focus solely on some markets (like Asia, for example, and thus don’t reach UK players).

If you are from one of the restricted countries for a specific game, simply choose something else from a different software provider that you want to try.

SlotsCalendar Advice: If you’re SOLELY interested in free slots to play for fun with free credits, then you can use a VPN to try them. Keep in mind that you shouldn’t do this if you’re looking to play for real money, as it is illegal to play at casinos and fake your location, and it is also unsafe. 

While before 2020, a reason why free slots to play for fun wouldn’t load could also be that you don’t have Adobe Flash Player installed; you should know that since 2021 all Flash content has been blocked or transformed. This means that some very old demo slots for fun only free are no longer available to anyone and that popular ones have been remade using HTML5, so they should be available to the general public.

The History & The Future of Slot Machines

History is a fascinating subject in itself, and so is online gambling once you start delving deeper. Our team at SlotsCalendar boasts a level of expertise not only out of professionalism and ambition but also because we’re students of the game.

We’re passionate about all aspects relating to slots: the reason behind their popularity, their technical intricacies, and how casino operators employ them. Consequently, we consider the history of slot machines as an essential piece of context that can serve as more than an interesting piece of trivia.

In our attempt to determine where the winds of progress are taking us, we will get you through the rise of slot machines and what their future looks like!

The Dawn of Slot Machine Gameplay

Scholars of history rarely agree on a consensus when it comes to the beginning of a historical current. However, in the case of slot machines, those who’ve studied the gambling phenomenon seem to agree that 1891 is the year of the slot’s invention.

This mechanism, more of a proto-slot machine rather than a fully-fledged one, was developed by a Brooklyn, New York manufacturer by the name of Sittman and Pitt. This device used real cards and a mechanism that randomly drew 5 cards to form a poker hand. According to the hand, the establishment (such as a bar) would reward the player.

As such, this system became very popular on a local level and then spread nationally. Its only downside was its arbitrary payment system – a problem later solved by a genuine pioneer.

The Fey Revolution

Charles Fey was a German-born mechanic who immigrated to the USA as a young man, later settling in the San Francisco area. His work as a mechanic led to him starting his own company along with a couple of associates, one of whom was Gustav Friedrich Wilhelm Schultze.

Schultze’s design, the ‘Horseshoe Slot Machine’, was the first to feature an automatic payout system, which was later improved and adapted by Fey to offer coins upon winning. As a result, his design became incredibly popular, and demand started rising.

The Liberty Bell

It was in the mid-1890s that horseshoe-inspired slots started taking off in popularity, even though California had yet to legalise gambling. After the 1895 release of this slot, the next step in Fey’s career was also his biggest hit.

The crowning jewel of Charles Fey’s impact on gambling is the Liberty Bell Slot Machine – a game he designed in 1898, whose automation included a 3-bell line that paid 50 cents. This slot was widely popular within the scope of Fey’s local market.

Since registering a patent was impossible due to gambling’s illegal status in California, Fey’s competitors greatly replicated this game mechanic, leading to this system’s constant rise in popularity.

Electromechanical Slot Machines & Further Technological Advancements

Since the USA went through various periods of prohibition, economic crisis, and war, the slot machine market has had quite a slow rise in innovation. However, as the 20th century went on, it heralded a new change that allowed the gambling industry to further advance technologically.

Bally, a company with a rich history in gambling that’s still a household name in the present industry, brought a game-changing game in 1964. Money Honey was the title in question, employing an electronic system to complement its mechanical hardware.

Its main electronic part was its screen and the slot used it for showcasing the results of each rotation. As soon as you pulled the lever, the reels would turn, and your winnings would show up on the digital screen.

Trend-Setting in Las Vegas

They call Las Vegas the ‘Entertainment Capital of the World, and the gambling side of the city’s economic activity stimulated innovation. Fortune Coin Co., a company headquartered in Vegas, used a Sony television unit and created the first video slot in 1976.

The system went through a modification process that culminated in several anti-cheating systems, followed by the approval of this patent by the Nevada State Gaming Commission. After several trials, the patent became popular among the Strip casinos, and Fortune Coin was acquired by the giant we know today as IGT.

Progressive Jackpots

Jackpots are the promise of a life-changing experience that can occur with the pull of a lever or the push of a button. When these rewards appeared on the scene of gambling, their attachment to a slot made that game instantly popular. Even today’s free slots try to replicate this feature when mimicking a title.

When these progressive jackpots appeared in the halls of the most popular Vegas casinos, the extreme gratification of winning the big one popularised slots even more. As gambling moved towards the digital field, progressive jackpots remained a mainstay.

Video Slots & The Full Rise of Digitalisation

Even in the crude and somewhat rudimentary dawn of the internet age, we’re currently living in, slots and online gambling, in general, showcased the signs of true ascension. Video slots – the standalone slot product dedicated to the digital space – have been around since the turn of the 21st century.

Once the significant names in land-based slot production saw the potential of the online sphere, they started adapting to a new market. By continuously innovating their technological base and using an RNG-based system for fairness, they started developing a competitive product for a new era of gambling.

The Market Gets Even Busier

Despite the interest in the creations of studios such as Micrograming, companies like NetEnt started raising the quality bar. The graphics, animations, and overall production credentials saw a skyrocketing rise across the entire industry.

The innovation factor was most apparent with the appearance of new and exciting gameplay ideas. These are the beloved mechanics such as Big Time Gaming’s Megaways, Pragmatic Play’s Drops & Wins, appearing across the 2010s and revolutionising how we saw the complexity of online slot machines, including free slots.

What’s Next For Slots Machines?

Slot machines are here to stay, and their ever-growing popularity is concrete proof. Innovation remains both a consistent goal and a mainstay phenomenon in gambling, especially in its digital form.

New concepts and complex game mechanics appear every day, powered by the industry’s luminaries and the passion for offering you an improved product. Slots with intricate, carefully designed 3D graphics, complex automation, and even virtual reality-augmented experiences herald a bright and exciting future for this entertainment avenue!

Already, we’re seeing game developers pushing the boundaries of casino games – and whether it’s with social gaming, 3D slots or virtual reality games, it’s clear that game developers are keen to innovate and continue pushing new ideas and concepts in their new video slots.

Trying to pinpoint the hottest trend to consequently appear on the market is hard, but VR certainly looks like a strong contender. Regardless of what may prove as the next big thing, we can assure you that these new-age titles will appear as free slot games on our platform!

Type of Free Demo Slots

• Video Slots – Some of the most famous kinds of slot games ever made, these are the more elaborate, beautifully designed and with many bonus features. More like video games in terms of graphics and animations, these slots have more reels, rows and paylines (or even ways to win or megaways) and more bonus rounds than classic slots while also bringing you intricate themes.
• Progressive Jackpot Slots – These games have progressive jackpots, and the jackpot prize pool will grow incrementally with each bet that’s made on them, thus reaching exceptional heights. The biggest one won until now is around £30 million.
• Classic Slots – These are similar to the first slot machines ever made. Classic slots have a 3×3 reel grid and a single payline (or more, but still fewer than video slots), no bonus features or special symbols (or, again, very few). Some classic slots look a bit more like video slots but maintain the classic symbols such as sevens, bells and BARs.
• Fruit Slots – Fruit Slot Machine are definitely classic slots and very widespread. These slots with a fruit theme make players nostalgic for the good old days of playing in brick-and-mortar casinos and even bars where all you had was a huge old slot machine that gave out a couple of coins.

Slots by Features

When you first start playing demo slots for fun, you will soon realise that not all symbols are the same. First off, they pay different amounts, and you have low-paying and high-paying symbols, but even further than that, they have special symbols that will either pay you for each individual symbol no matter where on the grid it is, or they will trigger bonus features.

The first and most common special symbol that you will encounter is the wild symbol. You could encounter many different kinds of wilds, like stacked wilds, sticky wilds, multiplier wilds, and expanding wilds. This one will replace other symbols to help form winning combinations.

Another important special symbol is the scatter. Scatters are of mainly two types. The first kind is the one that pays out different sums no matter where on the reels it is (usually upwards of two scatters), and the second kind is the one that not only pays out but it also triggers a bonus feature: free spins, click and pick games, arcade-style bonus features and many other kinds.

Most bonus rounds are triggered by getting three or more scatters. Still, there are some that can happen randomly or by collecting a certain amount of a set symbol, getting successive winning combinations or even not getting them.

These are the most common and also the most popular bonus features:

• Free Spins: Definitely, one of the most used but also the most sought-after bonus features, a free spins feature can have from 5 to unlimited free spins.
• Progressive Jackpot: Usually triggered randomly, the progressive jackpot is the kind of bonus feature one can dream about, but it rarely shows up.
• Re-spins: Re-spins are a sort of free spins. You might get them because you only have two scatters and need three to trigger the free spins, and it’s like a second chance.
• Pick-A-Prize: Also known as a pick-em game, pick-me or pick-and-win, this bonus feature is usually themed like the game and will have you pick from a number of objects.
• Arcade Bonuses: These are entirely different from one game to the next, but most of the time, they are similar to arcade games in the sense that they feel like a skill game in which you must catch or shoot or do something.

Slots by Software Providers

• NetEnt – NetEnt is one of the most famous casino software providers and has some incredible slot games for players to enjoy, including world-renowned titles like Starburst, Gonzo’s Quest, and Dead or Alive.
• Microgaming – Microgaming is a giant in the industry, and while it has hundreds of epic titles, Mega Moolah is by far the most beloved, as it has paid out some of the biggest progressive jackpots of all time.
• Pragmatic Play – Pragmatic Play is a lot younger than the other providers on this list, but its games have been winning award after award. Also, their Drops & Wins tournament is 100% worth checking out.
• PlayNGo – Another award-winning provider with decades of experience, PlaynGo has several titles worth your attention, like Doom of Egypt and the Rich Wilde collection.
• Playtech – Playtech has the Age of Gods series, which is a must-try for all players who enjoy mythology-themed free slots.
• IGT – Cleopatra and Davinci Diamonds are the options you can’t miss from this giant’s collection.
• EGT – EGT has hundreds of amazing titles, and they are all connected to the four progressive jackpots, so you stand to win some pretty hefty sums.
• Novomatic – There are many games by Novomatic (who now go under the Greentube name for online slot machines), but Book of Ra Deluxe and Sizzling Hot are the most famous ones.
• Yggdrasil – Yggdrasil is pretty new compared to other giants, but the design of their titles is unparalleled. They shy away from boring themes and always surprise us with something unexpected. Vikings Go Berzerk, Seasons or Beauty & the Beast are a couple of games you should check out.
• Big Time Gaming – BTG is the inventor of the Megaways mechanics, which changes the world of demo slots for fun only free forever. White Rabbit, Bonanza and Extra Chilli are just three of their best games.

Themed Slots 

Playing the same demo slots over and over would get boring, but luckily it never will because there are countless themes you could try that change every casino game.

On SlotsCalendar, we’ve made sure to divide our free slot games by categories according to themes so that if you’re into one of them, you may go straight to that theme and play in demo mode all the free slot games that share that particular theme. You can find games with mythology or historical themes, Egyptian stories, just fruits and sevens, underwater-themed movies, songs, manga, and anything you are able to think of.

These are our top categories at the moment:

• Cleopatra Slots: These free slot games stand out because this female ruler is a model of beauty, intelligence, power and wealth even now. These great games have excellent graphics and entertaining bonus features.
• 777 Slots: Another kind of classic free slot games that’s all the rage is the 777 kind. Seven has always been a lucky number in many countries from around the world, and it comes as no surprise that three 7s or five 7s will be extremely lucky in slot games as well. Sure, the graphics and the bonus features are basic, but the payouts are incredible.
• Halloween Slots: Zombies, vampires, werewolves, ghosts, and witches are all waiting for you in our Halloween collection. Halloween is one of the most beloved holidays, so there’s no wonder that people want to play these games. No matter if it actually is Halloween or not, they are still super fun, quirky or creepy.

Demo Slots vs Real Money Games

Slot Licensing and Regulation 

In a perfect world, you will only play at licensed and regulated online casinos when you play for real money, and you will enjoy demo slots for free from providers that are regulated.

We hope that what we’ve kept telling you has stuck and that you will put your safety first and play responsibly. In the online gambling world, there are several gambling regulators (which all have different jurisdictions), and they all have their own sets of rules and requirements that both providers and operators must follow in order to be granted that license.

In Europe, the main actors in the licensing business are:

• UK Gambling Commission
• Malta Gaming Authority (MGA)
• Alderney Gambling Control Commission
• Isle of Man Gambling Supervision Commission
• Curacao
• Belgia Gambling Commission
• Denmark Gambling Authority
• Spain Gaming Commission
• ARJEL (France)
• AAMS (Italy)
• ONJN (Romania)

Some are stricter than others, like the UKGC and the MGA, and others tend to learn from them and impose similar rulings. While, in general, most of them are working hard to make it harder for operators and providers to cheat players or harm them in any way, there is one license that you should trust but keep an eye on it at the same time.

The Curacao licensing committee is the largest one in the world, and they have given out the most licenses, but they give them easily and acquiring a license is quite cheap. This doesn’t mean that all online casinos with a Curacao license are bad; it means you should pay attention and make sure that you are safe at all times.

While most regulations that come from these gambling commissions are about what the online casino can and cannot do and how they should operate their business, there are rules for the creative studios making the games as well.

Here are a couple of highlights that might interest you:

• You must be able to access information about how the game is played, find a paytable and rules.
• Games mustn’t look like they are targeted at children.
• You must be able to find the RTP (return to player rate).
• The game must be certified by an independent testing house (GLI, eCOGRA, iTech Labs, etc.) and constantly tested for randomness.
• A spin has to take 2 seconds or more.
• Players can’t use the autoplay feature for more than 100 consecutive spins.

When to Switch to Real Money Play?

The most straightforward answer is – whenever you want to. But that’s assuming that you’re playing responsibly and have a plan.

We recommend that you stick with free slots to play for fun until you’ve familiarised yourself with the game, understand how to play it, and have decided that it’s worth risking your funds to try it for real.

Obviously, you’ve made a budget and know how much you can afford to lose going in. but that’s not all. You should have a game plan for where and how to play as well. First, you must take a look at our list of best online casinos.

You should pick an online casino that’s safe and reputable but also start small. This means, especially if you’re a beginner with no experience in the online gambling world, starting with low deposit casinos; this way, you won’t invest too much, and if you lose, the loss won’t be devastating.

If you’re mainly interested in slot machines, then go for slot sites where you will find this game type almost exclusively, so you have a better chance of discovering the newest games and all popular titles.

And the most important tip of all – find the happy middle and keep playing for free, but this time keep your winnings. By using no deposit free spins bonuses when playing for real money, you can play your favourite slots for free because you’re using the casino’s funds. Still, if you get lucky and complete the wagering requirements, you will be able to keep your winnings.

Always Play Responsibly

Playing responsibly is key, no matter if you’re trying to play free slots or give them a shot for real. Gambling addiction is a real problem, and it affects more people than you think. That’s why you should always pay attention to your gambling habits and keep assessing if you have an issue or not.

There are plenty of authorities that can help you. But it shouldn’t get to this level if you practice responsible gambling and make sure you play smartly. The way to do this is to do your research, play free slots for practice, set a budget when you switch from demo slots to playing for real money (and 100% stick to it) and make sure that you don’t make rash decisions.
