Free Slot Games with Bonus Spins

Playing slot machines for the fun of it has always been an incredibly popular pastime, and one that is likely to stick around for a while yet. Bonus spins on the other hand are virtually the same thing right down to their core — only difference is you keep what you win. How is this possible? It's simple: you take advantage of the right promotions. Any welcome bonus you see will be your friend for this, but we'll get to those a little later.

Most of the best online casinos have a steady mix of popular free slots games titles, and relevant bonuses for you to play around with — meaning anyone with an active email address and internet can do this (some sites allow you to play offline so you might not even need that). We'll admit, this can be pretty confusing, but keep reading and you'll be an expert in no time. Today we'll be covering these key points for you:

  • Why you should play free slot machines
  • Looking at the best bonus rounds in these online slots
  • Extra spins offers in online slots, and what to look out for
  • How you get free spins, and our signing up guide
  • The best free mobile slot options

We'll also be touching on other topics, such as: what a wagering requirement means, and how beneficial no deposit bonuses are compared to other popular promotions. Once you're finished here, you new players should be able to play with the utmost confidence across a variety of online casino sites!

Why Play Free Slot Games

Playing slots doesn't have to be strictly for monetary gain, you can have just as much fun by enjoying your surroundings, or the bonuses you find in-game, than worrying about your bottomline. Free spins offer unlimited possibilities that aren't limited to how much money you have on your account, but by how much time you are willing to put in. Free slots were made with fun in mind, it's why the developers let you play them with no strings attached via demo modes or free play.

We believe everyone should play one slot at least once in their lives, which is yet another reason why free slots are great, as they provide a taste of the igaming industry to aspiring new players! And who knows, maybe they decide to make their first deposit and play for keeps; everyone has their own preferences. But what other benefits come with playing free slot games?

  1. New customers who have no prior experience can get a simulated version of the real deal by playing without any real skin in the game.
  2. Intermediate to veteran players can use these spins as an opportunity to practice and get better in select titles.
  3. Dedicated players can use these rounds as a break from long sessions chasing real money.

Bonus spins have their onset advantages too, although they tend to be tied to a set deposit offer which might ask that you place a minimum deposit of around £10 — unless they are that of the no deposit required variety. New players will have the best seat in the house in all this as they get to opt into the best free spins offers/promotions, as those are normally reserved for them. Existing players who might play the odd slot game for fun don't have this luxury.

Best Bonus Rounds in Slots 2021

Bonus rounds (slot features), can be found in both free play and bonus versions of the same  free online slots game. Without these features, each of these slots would be near identical to one another outside of their appearance (except for cluster and megareel games, those are very distinct). In this section you will find some online slot games that showcase the best bonus rounds out right now. New customers, this should give you a good idea on where to start:

  • Rainbow Riches (Barcrest): An Irish-themed slot game like Rainbow Riches is always a great choice due to the bright colours and extensive list of bonuses available in this 5 reel game from Barcrest. The infamous Road to Riches bonus triggers when you land three leprechauns on the reels, you'll then be whisked off to another screen where you'll need to spin the wheel to earn multipliers as you travel this windy path.
  • Fluffy Favourites (Eyecon): An instant classic, and one of the most common slots you'll see tied to free spins bonuses! Fluffy Favourites from Eyecon is a 5 reel trip to the funfair, one that is full of pink elephant scatters and so much more! The free spins feature here will award you 20 free spins for landing four scatters in the same line, good luck. The Toybox Pick mini-game feature is fun too; think hook-a-duck but with better prizes.
  • Vikings Go Berzerk (Yggdrasil Gaming): A slot game for the ages, introducing: Vikings Go Berzerk, a 5 reel adventure like never seen before! Pillage the treasure chests feature here and you'll be a very happy man/woman, as you have the chance to win up to 40x your stake or up to 21 free spins. Speaking of which: you can actually win 10 free spins if you head on over to Thor Slots and activate their welcome bonus (terms and conditions apply).
  • Street Fighter II (NetEnt): NetEnt's Street Fighter II is unlike any of the other online games we've mentioned already. Here you'll be asked to choose your fighter, exactly like in the original, and go toe-to-toe for wilds and so much more against actual opponents. That's right, you fight other characters, and successful spins damage them. The car smash bonus game is fantastic too, giving you up to 15x your bet for simply destroying a vehicle, sign us up!

Free Spins Offers for Slot Games UK

Bonus offers of all kinds will let you play for real money, with free spins bonuses known for being the best of the bunch. Free spins no deposit bonuses in particular are incredibly popular, and can be found spread across most, if not all online casinos. You see, bonus spins almost never appear on their own, they are always accompanied by another incentive to help evoke those 'win real money' thoughts.

A no deposit offer essentially lets you play for free with real money stakes (terms and conditions do apply). Every other major bonus will ask that you make a first deposit, or come with deposit free spins just with 'no wagering' in place of the 'no deposit required' tag. Other types of promotions do exist, but we find these to be the most common, and the best free spins options out there.

No wager casino bonuses allow you to bypass the wagering requirements you find with every promotion. New players, a wagering requirement is what keeps you from signing up, potentially winning money on a free spins offer, and never coming back . Any winnings you earn goes into bonus funds, and cannot be withdrawn until you stake x amount to make it yours for real this time. All licensed and regulated online casinos abide by these requirements.

Every free spins bonus you see will select specific slot games for you to play in, and can differ in terms of how many free spins you get to play with. Some will give you as many as 5 free spins, others, up to 100. Here are some examples of how they look across the whole online casinos spectrum:

  • 20 Free Spins in Starburst, No Deposit Required (ts and cs apply)
  • No Wagering Requirement Bonus: 10 Free Spins in Eyecon Slots
  • 5 Free Spins in Book of Dead, No Wagering Requirement (Use Bonus Code PLAY5)
  • No Wager 20 Free Spins (Deposit Required)

Every online casino site you come across will have their own deposit offers/promotions — new customers should know that they have a bonafide treasure-trove of sites to dig through. At Thor Slots, the welcome bonus will give you one free spin on their Mega Wheel. One can win up to 500 free spins in Vikings Go Berzerk, Amazon vouchers, and all kinds of other goodies (no bonus code required, but terms and conditions do apply). 

How to Play Free Slot Machine Games

To play free slot machine games you will need an account at the participating online casino site. Some online casinos let you play games for free without registration, but having an account comes with so many additional features/perks. Don't have an account? Follow these very simple steps to create your account and claim your online slots/casino games bonus:

  1. Find a site that offers bonus spins on sign-up (Thor Slots for example).
  2. Input your personal details (name, address, email, etc.).
  3. Verify your account through the link sent via email.
  4. Head to the promotions page and claim your free bonus.
  5. Play the online slot/casino games the bonus Selects. Usually, Book of Dead, Fluffy Favourites and Starburst.

Free slots bonuses are very alluring, just make sure you aren't visiting an untrustworthy source. If you're going to play with real money in any of these online casino games, ensure that you find a site registered by the correct gambling commission. Not every casino provider will have this stamp of approval, so ensure that you do your research ahead of time. Play only the best online sites and you won't have to worry about a thing.

New players, you don't always have to play for real money if you don't want too either. Demo games, sometimes referred to as 'free play', give you the chance to play for the fun of it all. The fundamentals of all these online casino games are the exact same when you play for free or with real money on the line too. You don't even have to be one of those new players to jump in either, you are more than welcome to simply practice, or try out an alternate strategy without spending a thing!

Free Mobile Slot Games to Play

Casino apps are an option available at select online casino sites — although they tend to be exclusive to some of the larger sites. Using the apps won't help net you a max win or anything, but they do make the process of hopping-on and hopping-off at a moments notice that much easier. For example, Thor Slots has an app, and has an online casino site optimised for mobile gaming, giving you plenty of options when on the move. Here's how you can play games at the site from your phone:

  1. Open your Chrome/Mozilla/Safari/Internet Explorer browser and visit their site.
  2. Click/touch the sign in button and input your details, or create an account (this takes literally seconds).
  3. Tap on the online slot game that you want to play and simply wait for it to load!

The experiences of playing online slot games/casino games are roughly the same, if not better depending on what your preferences are. Most online slots you come across nowadays have all been made with mobile in-mind clearly. Free spins bonuses, no matter how many, can be played on mobile too for those wondering. This is obviously quite ideal for busier players, as most offers expire after 7 days if not claimed or used.

You can still win real money on any app or mobile site, which if anything gives you more choices in where and when you play as long as you have a decent signal. Some free games can be played offline too if you're the fun type. Slots like Rainbow Riches, and practically all others, can be played for free on mobile through the demo, or free play mode they offer. Again, playing for free is just as rewarding as real money games as the experience you gain can be priceless!
