Free slots and demo slots, they are mostly the same thing just gone by a different name. The free slots tag can often be tied to certain online casino bonuses where you can win real money, but we'll be covering those a little later for you. You see, you don't always need to be of the 'playing for real money' mindset. Playing slots for fun is like going back to your roots, a time when you could enjoy these casino games without the added fuss.

We'll be going over everything there is to know about free demo slots, how they differ from play for real money games, and the similarities between the two (there are quite a lot). More specifically though, we'll be breaking down:

  • What we mean by no download/no registration
  • A rundown of how you can start playing demo slot machines
  • How you can play the best free slots and still win real money
  • Free mobile slots and how you can play via mobile device
  • A guide to slots in general
  • The developers behind these casino games
  • Your frequently asked questions (FAQs)

Anything that isn't clear as we go should be covered in the FAQs.

Not to worry though, playing free is a very easy concept to grasp — even for the newbies. It's only when they have real money promotions thrown in where things get slightly complicated.

Free Slots No Download No Registration

Normally, when you visit one of these online casinos you are asked to register with the site in order to play. Some casino slot games sites get rid of this requirement completely, allowing you to simply enter as a guest and play some of the best free online slot games around. There is no real caveat to playing at a free casino either, take a look for yourself — plenty of sites are in on this. No registration is essential for play for fun players.

No download is similar to no registration in that you aren't asked to install something in order to play. Certain casino sites, without naming names, sometimes ask that you download something to play (Flash for example). If one of these online casinos have the no download label, it means you can play on any and all devices and still enjoy seamless gaming! This is ideal for those with slow internet speeds, time constraints and spyware concerns.

Again, here is a summary of the pros of playing free online slots with no download, and no registration requirements:

  • Easy access, simply visit the site and play.
  • No possibility of lost personal information or spyware.
  • Great for slow internet speeds, and those with little time on their hands

Sites understand that convenience trumps all, which is why they let you play for free without having to go through the standard protocol. Some of you out there will care about not stating your personal information unless you have to, and having no download/no registration is, easily, the best way to appeal to those sorts of punters. Make sure you find sites offering both no download/no registration if you wish to play hit slots games without all the added noise.

Guide to Start Playing Demo Slots

Playing slot machines in free play give you the best possible seat in the house. Why is that? Well, the benefits of playing free is simply this: you get to enjoy all the best slots for fun, which is what they were intended for in the first place. All the popular slots can be spun this way too, it isn't exclusive to a select few — although there are certain Megaways/Progressive Jackpot slots that don't fit this criteria.

You have the option to play a mix of classic slots, like the fruit slots of old, and various modern video slots that feature on the front page of all the reputable casino sites! The sky is the limit when it comes to playing free, not to mention the lack of pressure one might have when compared to playing for real money. Our advice: ask yourself what sort of player you are that day and decide from there. There's no real rush to jump in here either, take your time; with demo slots games you have all the time in the world.

Most of the slot machines you see come with a demo mode for you to play, how you access them can be as simple as hitting a button with the word 'demo' written on it before the start of each round. Don't hit autoplay as that plays with real money still, only difference is the CPU plays for you. Here is a more accurate rundown of how you can play slots for fun via demo:

  1. Visit the free casino site you want to play at.
  2. Click on/touch the slot games you like the look of.
  3. Hit the 'demo' button to play slots for fun for as long as you like.

Playing for real money can be easier when you know what you're getting yourself in for too. Say you want to understand the many bonuses in Immortal Romance before you pay to play. Well, why not play for free via the demo and get a feel for it, earning valuable experience in the process! Demo is not exclusive to new players, it is open to all. An online casino like Thor Slots is a great choice for those wondering where to start.

How to Play Free Slot Games & Win Real Money

Yes, it's entirely possible to play free online slots and make real money in them, which is crazy to think about. How does this work? This is where the distinction between free slots/free spins and demo slots come into play. Free slots/free spins are often tied to certain online casino promotions, which come in all shapes and sizes, choosing select slots for you to enjoy. In short: it's entirely possible to play for fun and make real money as you go.

To make real money you will need to find specific casino promotions, as not every incentive you see will let you jump in without paying a deposit. Look for the no deposit free spins bonus over all others, these are your ticket to win real money directly. If you want to take part in these play for real money spins you will need to register at the site you're looking at. The process of signing-up takes seconds, take a look for yourself:

  1. Find a site that offers free spins no deposit on sign-up.
  2. Enter your personal details. (name, address, email, etc.)
  3. Verify your account through the email link.
  4. Head to the promotions page and claim your free bonus.
  5. Play the slot machines exclusive to the bonus. (normally in well known slots like Book of Dead)

All the best online casinos will offer promotions such as these. Thor Slots, for example, are giving new customers the ability to spin their Mega Wheel for the chance to win up to 500 free spins in Vikings Go Berzerk, alongside other prizes in Amazon vouchers and free spins in other hit slots from all the big developers (terms and conditions apply). An online casino bonus such as this is fantastic at giving you the greatest head start.

Unfortunately, one will have to register to take advantage of these popular slots promotion. We'd honestly recommend having a site anyway if you're planning on sticking around at a casino site. No registration only really benefits part time players who might only spin once every week if that. Once you've signed up you have access to a range of perks in well known slots from the likes of Red Tiger Gaming, Big Time Gaming and all the best software providers!

Why online gambling providers offer these sorts of incentives? They do it to give you a taste of what it's like to play for real money in hope that you make a deposit and continue spinning. Remember, certain jackpot/progressive jackpot slots can only be played with active funds, and they are some of the most fun you'll have in this medium! Real money slots are equally as fun as free online slots, trust us.

Free Mobile Slots

All the best casino games can be played completely free of charge across all devices — this covers around 95% of all slot machines/casino titles to be completely honest. Software providers understand that having a mobile option is the desired approach as it appeals to players everywhere. You can do a lot on a smartphone nowadays, and playing online slots is definitely up there with all the best activities, especially if the site you're at has an app.

This slot game has a story at play, making return spins highly likely.

How to Play Free Demo Slots

Slot games are very easy to understand, all it takes is practice — although you might only need a handful of spins to get the hang of them. Demo slots are a fantastic opportunity to practice, and should be used by all novices looking to hone their skills and get better, perhaps to the point where they can challenge most progressive jackpot games!

Not sure how these online slots work, or how to get started? No problem, here is how you would normally get the action-rolling:

  1. Click on the slot game of your choosing
  2. Choose 'Demo' or skip this step
  3. Select the number of paylines and your stake (use the +/- to lower and raise the bet)
  4. Hit 'Play' or 'Spin' to have the reels kick into motion
  5. Wins arrive when corresponding symbols link on the same line (normally from left to right)

Slots can be broken down into very distinct elements, after all, not every slot was made from the same mould. Playing slots online can be very rewarding in the same way video games/mobile games are — in fact, both borrow from one another, be it through graphic choices or mini games. Know that there are plenty of free slot/real money games out there, don't settle for just one.

  • Graphics: Outside of the bonus features in slots, the graphics/art style is what separates the games themselves. Practically everything you can think of has an online slot, either based on it, or inspired by it. Irish slots, Egyptian slots, Fruit slots and licensed slots are the most common of all slot games. Video slots are the best options if you care about immersion, showcasing the true power of these slots online.
  • Bet Sizes: There isn't a one size fits all sort of deal with minimum/maximum bet sizes, each slot you see ask that you pay different amounts to play. Some online slots let you play from as little as 1p up to £100, others 25p up to £250. Do your research ahead of time to find out how much you can play with. Free online slots obviously bypass the need for this.
  • Volatility: Online slots all showcase varying volatility. You see, some slots provide wins more frequently than others. Volatility dictates the risk involved, the lower the volatility, the better your chances are of coming out on top. High volatility games are tricky, but they often come with progressive jackpots for you to chase, which will play to experienced players more.
  • RTP: Similar to volatility, RTP will dictate how much money you end up with on a win. RTP stands for 'return to player' and can range anywhere up to 97%. If you are going to look for the best slot games, always seek those with the highest RTP as they will give you the max amount of cash on all wins compared to lower games. RTP shouldn't matter too much in demo slots, but still.
  • Bonus Features: Every slot you see will have bonus rounds of some kind, these make gameplay rewarding and fun. Fruit slots tend to limit how many bonuses they have within, but those are slots for fun and aren't really going to break the bank. Wilds, scatters and free spins are all examples of bonus features. These three can be found across most online slots, and in a way are inseparable.
