Have some fun with +5000 online slots in demo mode, see our slots calendar and read our detailed reviews — no need to download or register.
The best things in life are free, that’s how the saying goes, and if we’re talking about free slots to play for fun then this definitely rings true. There are two types of slot games you can play online: demo slots which are played for free and slots for real money. While online casinos offer the real money kind (some also offer a demo version), SlotsCalendar offers only free slots (and a link to the best casinos where you can play them for real).
All the hundreds and hundreds of slot machine games on our website have a play for fun link that allows you to play demo slots for fun whenever you want, from wherever you are because they are available 24/7 across all devices.
Free slots have a lot of advantages, for both new and experienced players. When you choose to play slots with demo play on SlotsCalendar, you get to play them with no deposit, no download and no registration required. You just enter the website, pick the game you want to try, click the play button and start playing right away. You don’t need to enter any data at all, no need for any additional things.
The main advantage that comes to mind when playing slots for fun with no money is that it’s completely free, there is 0 risk involved and you have nothing to lose. While there is always even the slightest risk of losing when playing for real money, this can’t happen when you’re playing for free.
Another great advantage of demo slot games is that you get to play the newest games that haven’t even been launched in online casinos yet, you get to test everything and know exactly what games you like without having to bet on it to find out.
Our research team is focused on reviewing every single slot game so that you can make informed decisions and know what every slot has to offer, whether it’s worth playing or not and if not what else could you play instead from the same software provider or the same category. You get details about the graphics, the theme, the bonus features and even Pros and Cons for each slot so even before you hit the play for free button you’ll know what to expect. Check out any free slot you like, we’ve got your back!
If you’re a new player and are just now getting into online gambling and playing free slots, then there are some terms that might confuse you a bit. We’ve compiled a list of common slot machine terms that you will encounter so that you can understand them better:
👉Paylines: Paylines are the winning lines on which you need to make combinations to win. The number of paylines a slot game can have varies from 1 to 100. Usually, you will have to make combinations of three or more identical symbols (or in combinations with wilds) to get a payout, but unless the combination is on one of the paylines you’ve bet on you will not receive the payout.
👉Reels: The reels of a slot are the vertical divisions of the grid of the game. When you make a bet and press spin, these are the parts of the slot that will spin. You can have 3, 5 or more reels depending of the design of the game. Most of the time they all spin together, but there are some games that let you re-spin reels individually (for a secondary bet) in order to get a better payout.
👉Rows: The rows are the horizontal portions of a slot, the opposites of the reels. These do not spin, they are present only to make the division between symbols clear.
👉Paytable: The paytable is a table that you will find in the information section of a slot game (usually marked i) where you can see what combinations of each symbol (three, four, five etc of the same kind) will pay out.
👉Autoplay: Autoplay is a feature that many online slots have that you can set to automatically spin the reels for you for a certain amount of times (10, 20, 50, 100 etc) with a certain bet either until the spins end, until you trigger the bonus feature, until a certain win or loss.
👉Coins: Coins for slots come in many denominations from a penny to five pounds or even more depending on the game. You can choose how many coins you want to bet on a payline and also what your total bet is.
👉Credits: Credits are what the coins are converted to when they are in the machine. So let’s say you play on a nickel slot machine. If you insert a pound into the machine, you will have twenty credits on that machine to use them as you will.
👉RTP: The RTP or Return to Player is a term that casinos use to describe the percentage of all the wagered money a slot machine will pay back to players over time. So if you were to make a hundred £1 bets on a machine with an RTP of 98%, you can expect to get back about £98 in wins. The bigger the RTP is, the better your chances of winning are. You should try playing high RTP games, or at least don’t go lower than 94% (if you’re playing progressive jackpot slots).
👉Volatility: Volatility (often also called variance) refers to the risk and reward involved in the game. For example, high volatility means that the slot game will seldom pay out but when it does the prizes will be big, while low volatility means that the slot game pays often but with smaller prizes.
👉House Edge: The house edge is the casino’s advantage. All games have it, no matter if we’re talking about table games, live casino games, instant win games, slots or others. Assuming a slot game with a 97% RTP, the remaining percentage until 100% is the house edge. The bigger the RTP gets, the smaller the house edge becomes.
👉Software Provider: Software providers are the companies that create the slot games. Companies such as NetEnt, Microgaming, Novomatic, RTG, IGT and many others.
👉Reel Setup: The reel setup is made up of the reels, rows and paylines that each slot game has. For example, you could have a reel setup of 5 reels, 3 rows and 30 paylines.
👉Jurisdiction: Each country has different regulations and laws for online gambling, thus it is important that the game you want to play to be available for your jurisdiction to have the license that works for your country.
👉Bet Level: The bet level is the range of available bets you can make on a game, from the lowest one to the highest one. Like, for example, 0.10 to 100.00.
So you’re looking to play a great slot for free. Maybe you’ve searched for it from your browser via a search engine, maybe you’ve come straight to SlotsCalendar. Either way, once you’re here we have you covered.
If you’ve come here from a search engine then you’re directly on the game page, if you’re directly on SlotsCalendar (because you’ve bookmarked us or know how to find us) then you will have to either enter the name of the game in the search bar on the upper left side to find it or you can go looking for it in one of our many categories.
Another option if the game is new or if it’s not yet launched and are not sure what it’s called, you can look for it using the calendar functionality. Just click on each day and you will find the game.
Once you’re on the game page you will be able to read a full review about it or just check the main details on the right side, play the game and even grab a bonus or go play it for real money, your choice.
To play the game in demo mode these are the 3 steps you need to take:
1. Click the play button
2. Set your bet (number of coins, bet per line)
3. Press spin (or use the autoplay feature)
If you’ve played it for fun and now want to play it for real there are two routes you can take:
A. Click on the Play for Real button, make an account at the casino or login, search for the game, repeat the same steps as for the demo version.
B. If you want to also get a bonus, check the available offers on the game page and click on the one you like. Read its review, see if it fits your needs and if it does click on the Claim it button. Once you reach the casino, make an account or sign in, claim the offer and start playing.
The processes are the same no matter if you try them from a desktop/laptop or from any mobile device such as mobile phones or tablets because both SlotsCalendar and the casino’s we review are mobile-friendly.
If you’re looking to play for free, but win for real and also let your competitive side take the lead, slot tournaments might be exactly what you’re looking for. Slot tournaments allow you to compete against other players and receive a coin prize. It works like all other slots, you spin to win, but when you do win, you will receive points. The more spins and wins you get, the higher you rank and the better your chances of winning will be.
While some casinos have entry fees, on SlotsCalendar you will find plenty of online casinos that offer free slot tournaments which you can enter and win huge real money prizes.
When you first enter the online casino world you will notice just how many types of games exist. Sure you’ll find table games and scratchcards and live casino, but what you need to remember that these too have subdivisions. As the table games category includes baccarat, blackjack, and more, so does the slot category. We’ve decided to tell you a bit about the kinds of slots you can play on SlotsCalendar:
➡️Video Slots: Some of the most famous kinds 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.
➡️Classic Slot Games: These are similar to the first slot machines ever made. Classic slots, also called fruit slots sometimes, have a 3×3 reel grid and a single payline (or more, but still much less 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 fruits, sevens, bells and BARs, like Sizzling Hot from Novomatic.
➡️Mobile Slot Games: mobile games are considered all slots (no matter if they’re classic, video or 3D) as long as they can be played on a mobile device, they are mobile slots. The great news is that nowadays most games have been made available on mobile devices, either using Flash or HTML5 or other new technologies so that you can enjoy your favourite games anywhere you are. Thus if you like the game Starburst or Eye of Horus from Merkur Gaming you can play them on your phone at any time.
➡️Jackpot Games: Also known as progressive jackpot slots, these games have progressive jackpots and the jackpot prize pool will grown incrementally with each bet that’s made on them thus reaching exceptional heights. The biggest one won until now is around £30 million.
➡️Movie Slots or TV series slots: These games have a movie-theme (or a series one) in that they are almost identical or at least based on a great movie. The music is similar, the characters are the same and the overall feeling, maybe even features stay in theme.
➡️Comic Books Slots: If you love superheroes then you will surely love comic book- based slot games that feature your favourite characters. There are games that follow their journeys closely and they are usually filled with exceptional features.
➡️Television Show Slots: Even television shows get their own games and if you thought the shows were interesting wait until you see the slots! The 100K Drop, Love Island, Who Wants to Be a Millionaire and all top-grossing shows are available.
Playing the same slot 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 slot games by categories according to themes so that if you’re into one of them you can go straight to that theme and play in demo mode all the slots that share that particular theme. These are our top categories at the moment:
Cleopatra Slots: These slot games stand out because this female ruler is a model of beauty, intelligence, power and wealth even now. These great games have nice graphics and really fun bonus features.
Fruit Slot Machines: one of the most wide-spread slots, 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 and old slot machine that gave out a couple of coins.
Zeus Slots: some of the most appreciated slots are those of Zeus and Olympus. This Ancient Greek Gods theme is amazing because the storylines are exceptional, the graphics are outstanding and the bonus features are top-notch.
777 Slots: Another kind of classic slots that’s all the rage is the 777 kind. 7 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.
3D slots are the newest form of slots (except for VR slots but those aren’t as popular yet because the tech is not widely available). These slots have the best graphics as they seem super real and like they are coming out of your screen. 3D games have 3D graphics and HD sound effects that make the themes come to life, but also much more elaborate bonus features, way more than just free spins.
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.
3-Reel Slots: If you like that old-school game feeling then the 3-reel slots are definitely the right call for you. They may be small and may not have that many features, but the payouts are really impressive.
Megaways Slots: Megaways is a series of slots by Big Time Gaming which offer a high payout potential, higher volatility and tens or even hundreds of thousands of ways to win (compared to dozens of paylines or hundreds, maximum thousands for regular slots). This type of slots is so popular that other software providers have adopted it from BTG and are presently using it too.
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. This one will replace other symbols to help form winning combinations. Meaning that if you have 2 7s on a payline and then a wild on the same payline the combination will be considered a good one and payout. There are many different kinds of wilds you could encounter.
There’s the stacked wilds which are essentially a wild symbol that can cover an entire reel or more. While they are normally in clusters of 2, 3, 4, or 5 symbols you could potentially cover the entire reel set since many slots have the possibility of stacking symbols on all reels. Furthermore, you may find sticky wilds that remain in their place on different spins, for example during re-spins or free spins. Then there are multiplier wilds that add a multiplier to your combination (2x, 3x etc) which means that a 3x multiplier on a €100 win will bring you €300.
You may also have expanding wilds that will expand to cover an entire reel or spreading wilds or walking wilds that will either cover adjacent position or move one position to the right or left after every spin. The list can go on and on because software providers keep adding new and interesting types.
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.
This is one of the things that can set slot games apart. Each software provider will try to innovate and bring something new and exciting to convince you to try their games. And this is great news for you. Because you get a lot more fun and more chances of winning when you trigger the bonus features.
Most bonus rounds are triggered by getting three or more scatters, but 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. Also, it’s important to know that some slot games have more than just one bonus feature. For example, even a simple slot like Captain Venture from Novomatic which is quite old has several: free spins, multipliers and a gamble feature.
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 feature, 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 features you can dream about but it super rarely shows up.
🔎Re-spins: Re-spins are a sort of free spins. You might get the 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 completely different from one slot to the next but most of the time they are similar to actually arcade games in the sense that they feel like a skill game in which you must catch or shoot or do something.
Microgaming, NetEnt, Playtech and many other software providers offer progressive jackpot slot games, one bigger than the other and all constantly growing and resetting. Here are the biggest progressives:
Microgaming is one of the oldest and biggest software providers on the market. Not only do they provide hundreds of exceptional slot games, but they also rule the progressive game. Mega Moolah is one of their progressives and it’s also one of the most well-known ones in the industry, so much so that the game has several versions and several games contribute to it.
NetEnt has been the top runner for quite a couple of years now, and while we’re all mesmerized by the quality of their video slots filled with impressive graphics and innovative bonus features, we have to stop for a while at their progressive slots as well. They offer the huge Mega Fortune progressive, but also Jack And The Beanstalk and several others.
Playtech is another software provider giant that has the power to give you both amazing slots and amazing progressives. Many of their progressive jackpots are tied to several games such as Age of the Gods (the entire series of 5+ games) or Buffalo Blitz or on a single title like Beach Life.
Once you enter SlotsCalendar you will see our impressive collection of demo slots, but if you stick around some more, you will soon see that we also have a whole lot of slot bonuses.

We only pick the best offers from top, trusted online casinos and offer you a complete review about the offer so that you know right from the get-go if you’re interested or not.
While we do offer many great bonuses that have no wagering requirements, remember that most promotions have wagering requirements and other rules.

If you’re interested in the newest slot games (and even the ones that haven’t even been launched yet) you can check them all out. New online slots are just a click away when you’re on SlotsCalendar because we don’t have calendar in our name for no reason.
Here you can see the calendar and if you click on it, you will be able to see what games are launched on each day. You can go backwards or forward and just click on each day to see what’s new. If you click on one of the games showed there you will automatically be taken to it where you can play it, read a review or grab a bonus.
As we were saying before, demo slots can be played across any device of your choosing. While in the far past slots were only available at brick and mortar casinos and then they also entered the online world via desktops and laptops, now you can enjoy your favourite games on phones, tablets and even TVs.
In order for this to work new technologies had to enter the industry. Most slot games these days are made directly using HTML5 and Flash which allow for mobile play. These technologies have shaped the future of online slots because now everyone can have full access non stop, no matter where they are as long as they have an internet connection. You are no longer stuck at home or need to get home to play, you can do so from your vacation, while you’re on your commute home or even during your breaks at work.
Another great achievement of technology is that these games no longer require that you download anything. They are available directly from your browser.
On SlotsCalendar you will find a huge list of top rated casinos which is updated and improved continuously and all the casinos are thoroughly reviewed so that you can choose the best possible option when you decide to play for real.
At SlotsCalendar there is no register, no download and no deposit required. All you have to do is enter on your favourite slot, find the game you like and press play and you’re good to go. There are no other extra steps you need to make.
This page deals more with the practicalities of actually using a free slot machine. We know it’s important, especially for new players, to be able to try a slot game for free, understand how it works and what the rules are so that they can successfully play it for real in the future. Even for more experienced players, when a new game is launched you’ll know exactly what to expect from it if you play it in demo mode first. Furthermore, a review of the game can help highlight its features and design so that you know right away if it’s the right game for you.
Another point to consider is that maybe sometimes you just want to have a lot of fun without investing in it, just spinning to enjoy yourself. And so, for that reason, you don’t necessarily want to play for real, you prefer playing it for free. Whatever your reasons may be, playing slots in demo mode is always a good choice.
While when playing in free mode slots have no risks in terms of losing money, the game remains the same which means that slots are still addictive if you’re not careful. Remember to always practice safe gambling and if you see any signs of addiction you need to contact GamCare (UK players), CanadaSafetyCouncil (Canadian players) or any other similar entity for your country.
We have a dedicated page for Responsible Gambling, where you can find all the signs of addiction and the rules you need to follow to stay safe, check it out and make sure you’re playing for the right reasons.
