Guide to Start Playing Free Slots Games at SlotsCalendar

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.

Guide to Start Playing Free Slots Games at SlotsCalendar

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 favourite free slot machines, you may use the search function.

How to 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), as well as 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 you won’t miss out on great opportunities.

If you’re feeling social, you also have the choice of using social media and learning about new free slot machines on SlotsCalendar’s accounts:

Are Free Slots UK 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 of 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 that you want to try from a different software provider.

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

The online gambling industry is growing at an insanely fast rate, but to get to this point, it had to go through several defining moments. We don’t want to bore you with a complete history of slot games, so we’ll just give you the highlights:

  • Some say that the first slot machine appeared in 1891 and was created by Sittman and Pitt. It used playing cards and five mechanical drums. It cost a nickel, and it quickly took over the USA.
  • In 1985, Charles Augustus Fey created the Liberty Bell. This one didn’t have playing cards anymore and instead used symbols. The machine could now automatically give out payouts, as opposed to the previous game where you would have to claim winnings from the bartender. 
  • From 1902 until 1907, slots were banned.
  • In 1964, Bally invented the first electromechanical slot machine – Money Honey. This one had video graphics, a small display and a lever. 
  • Around ten years later, Fortune Coin, a software provider from California (later bought by IGT), used a 19-inch Sony TV to display the game’s symbols.
  • Slots continued to improve, slowly adding better graphics, bonus features, and progressive jackpots.
  • Once the internet appeared, it was only a matter of time until slots were moved online. Between 1990 and 2000, most huge software providers we know today appeared and started creating mainly video slots. Now the games worked using a Random Number Generator.
  • Most of them required that you download a client before being able to play, unlike today when you enjoy free slot machine games without downloading or registration.
  • More and more bonus features were added to the games, and graphics were taken to a whole new level; thus, most new games are 3D slots right now.

The History & The Future of Slot Machines

Everything is possible, whether it’s with a mix of different casino games, social gaming or virtual reality games. But what does the future hold for free slot play? Software providers are trying to find new and exciting ways to challenge us.

Game studios are coming up with new mechanics, like the already famous Megaways system of Big Time Gaming that’s being used by most top providers and improved consistently, NetEnt’s Infinireels or Yggdrasil’s Gigablox.

VR (virtual reality) is still the next big step for free slot games, although this change is coming slower than expected. It has the potential to bring players the best of both worlds and give them a fully immersive experience like they are in a real brick-and-mortar casino while having fun from the comfort of their homes. But the technology is still too new and the hardware too expensive for most players to enjoy.

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 realize 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.

We’ve Always Got Your Back

Those who wish to take a little break from free casino slot games can rely on us all the same. We have other types of free games you can try.

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 the 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 be 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 better chances 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.

Always Play Responsibly

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.
