Best Microgaming Slots of 2020

Naming the best Microgaming slots is a fool’s errand because there are so many to choose from. Your favourite game may not be the same as someone else’s. However, the Microgaming free slots listed below are generally accepted as bona fide classics in the industry and beloved by most people:


Game of Thrones

This is hardly a hot take, but Game of Thrones is massive, and tens of millions of people adore the franchise. Whether it’s the TV show or the books, GoT is big business. Microgaming developed an online slot game worthy of the fame of Game of Thrones. The company’s Game of Thrones is cinematic and beautiful to play.

It is aesthetically stunning, with an amazing colour pallet and world-class animations. This game still holds up visually in 2020 despite originally launching in 2014. The game is a 5 reel and 243 ways to win slot that puts players in the heart of the action on the continent of Westeros. Once you choose which House you want to play as you are plunged into a journey across the 7 Kingdoms.

2 or more Throne symbols on the reels will see a reward of a random cash prize that can be multiplied up to 1200x if 5 symbols are hit. 3 or more Throne symbols will trigger the Free Spins features, which provides you with one of four characters: Baratheon, Lannister, Stark, or Targaryen.

  • Baratheon – 8 spins with x5 multiplier and 3 stag symbols stack.
  • Lannister – 10 spins with x4 multiplier and 4 lion symbols stack.
  • Stark – 14 spins with x3 multiplier and 5 symbol stacks.
  • Targaryen – 18 spins with x2 multiplier and 6 symbol stacks.

You will want to hit the Game of Throne logo because it acts as the Wild symbol, which can also be triggered during Free Spins and can be stacked. As always, the Wild will substitute all other symbols on the reels apart from the Throne Scatter.

What makes Game of Thrones one of the best Microgaming slots is its gamble feature. Whenever you pick up a win, you can choose to gamble through a simple toss of a coin. When you select heads or tails, you will have a 50/50 chance of winning a bigger prize.

Mermaids Millions

While Game of Thrones is a high concept 3D online slot, Mermaids Millions is a more pared-back video slot with 5 reels and 15 pay-lines. However, its simpler gameplay and looks should not fool you because this is a stellar free Microgaming slots online game.

As the name suggests, this slot game has an underwater theme focused on the legend of mermaids. Despite the setting, there’s not much of a themed backdrop to this game because the reels fill the screen. That’s fine because it allows you to just focus on playing and enjoying the excellent gameplay elements.

Mermaids Millions is a fast-paced online slot and comes with a solid set of features. If you see the Mermaid King on the reels, he will act as the Wild symbol and replace all other icons aside from the scatter and bonus symbols. 5 Mermaid King symbols across an active pay-line will payout an instant 7500 coins.

Landing the Mermaid is also important because she acts as the Scatter symbol and can help form scatter wins which can be multiplied. Furthermore, hitting 3 of the scatters anywhere on the reels will start the Free Spins feature. Here you get an initial 10 spins with all wins tripled during the round. You can also re-trigger the free spins by hitting three more Mermaid symbols.

As for the Bonus symbol, it is a Treasure Chest that will trigger the bonus round if you get 3 or more on any active pay-line. Interestingly, the bonus round can also be triggered during the Free Spins rounds.

Book of OZ

Book of OZ is one of the best Microgaming slots and another 3D slot game that has a cinematic concept. As the name suggests, the game borrows its inspiration from the Wizard of Oz and functions across 5 reels and 10 pay-lines. Fans of the movie will quickly recognize all their favourite characters, including Dorothy, Tin Man, Scarecrow, and the Lion.

You will head down the Yellow Brick Road and contend with the Wicked Witch of the West to reach the emerald riches of Oz. With the Book symbol, you get a Wild and Scatter, which replaces other symbols on the reels to help form a winning line. As for the Scatter, the Book will have to land 3 times to trigger the Free Spins round.

If you do get those scatter Books, you can get up to 10, 12 or 25 spins to try and gain big wins. When the free spins start, you get a randomly chosen special symbol that will cover the whole reel and pay out on matches on an active pay-line.

One interesting feature of the Book of Oz is an extra spin on the base game. After every normal spin, you can select one reel to give an extra spin. Of course, this is useful if you think you can pick up a win by spinning one more reel. However, it does come at a price because only one reel can be changed.

It is worth noting when this extra reel spin is used, only wins involving the re-spun reel are valid.

Playboy Gold

Playboy Gold is a video slot game that features 6 reels and has a 100 pay-lines. As you can probably guess, it is inspired by the world-famous Playboy magazine and features Bunnies (not the animal kind) as its backdrop.

You won’t be surprised to find the popular Playboy logo appear on the reels, alongside some good old fashion card symbols. Your Bunny hosts will guide you through a game that is loads of fun with some interesting gameplay elements.

Without a doubt, this is one of the most lavish online slots you can play, complete with plush gold and dark colours that add some class to proceedings. Landing the Playboy Gold Bar will act as the Wild symbol and substitute any other symbol in the game but not the Scatter. Speaking of the Scatter, 3 or more of them will start the Wheel Bonus, which delivers cash prizes, more spins, or a match bonus.

If you see Playboy coloured logo symbols with a Jumbo Block option, you can play the bonus round. Each logo represents a Playboy Bunny:

  • Orange logo is Stephanie
  • Red logo is Hiromi
  • Purple logo is Gia
  • Blue logo is Carly

By landing one of these on a base spin you will trigger either a 5x multiplier, Credit Prize up to 30x the initial bet, and re-spins up to 4 spins. The Match Bonus happens on the Wheel when one of the Bunnies lands on it. During this game, you select cards and attempt to find a matching pair, with each match holding a cash price. If you win once, every subsequent win will payout on a 10x multiplier.

There is also a Free Spins round that you can trigger by landing the Black Playboy logo on the Bonus Wheel. Here you can play an extra 10 spins for free.

The Phantom of the Opera

With The Phantom of the Opera, Microgaming is providing another amazing video slot experience that boasts the company’s much loved 243 ways to win features. This means the 5 reel slot plays across 243 pay-lines. All the amazing spectacle of the musical is evident on this slot game, including a sumptuous design and wonderful audio score.

The Wild symbols is a Logo sign that can double stack itself onto any pay-line and replace any other symbol apart from the Scatter and the Letter bonus symbol. Seeing 3 or more Wild symbols on an active pay-line is good news because you can make some massive winning combinations with them.

As for the Letter bonus symbol, landing it allows you to win a random cash prize that can be up to 20x your first bet. It should be pointed out that this lucrative little bonus will only trigger if the Letter symbol arrives on the fifth reel only.

The Phantom’s Mask is the Scatter symbol and landing 3 or more will start the Pick Me selection bonus round. During this mini-game you will have to choose between 3 options: Masquerade, All I Ask of You, and Music of the Night.

Music of the Night – In this feature, you will receive 10 Free Spins with some cool additions: up to 3 Wild reels, Multiplier up to 4x, 5 random Wild symbols, and 5 further free spins. Interestingly, you can trigger more than one of these additions on a spin.

Masquerade – In this game, you will be presented with a choice of different masks and will have 3 picks to reveal prizes. Under the masks are level-ups to increase the prize, cash prizes, and the chance to get more picks.

All I Ask of You – This feature is also a Free Spins bonus that starts by giving you 10 free spins alongside the Dancing Wilds. These Wilds are the characters Raoul and Christine dancing alongside the symbol position during a spin. You can get several enhancers depending on which position the Dancing Wilds land on:

  • 3x multiplier on the same position
  • Both reels become Wild is adjacent
  • 1 reel becomes Wild is on the same reel as the Dancing Wilds
  • Expand to 2×2 Wild Block if diagonal

Jurassic World

Microgaming has shown how to take a mega movie franchise and turn it into an online slot that is just as amazing. Jurassic World is based off the $1.5 billion grossing 2015 smash hit film and is one of the best Microgaming slots around. It is a big production online slot game with stunning visual graphics and an amazing level of quality.

You can see the Jurassic World park in the background and of course, there are plenty of dinosaurs throughout the game. Be warned, you are entering the Jurassic World park, where Indominous Rex is out to get you… can you beat him and win cash prizes?

The classic Jurassic Park logo acts as the Wild symbol and will allow you to replace any other symbol in a game except for the Scatter. Wilds can also be grouped to help form winning combos and are stackable up to 10.

Looking for the Scatter symbol? You’ll need to land the yellow amber rock holding a mosquito. If you get 3 or more of these symbols you can get into the Free Spins round. 2 Scatter symbols in the base game will turn those symbols Wild, so there’s value even if you can’t get the Free Spins. However, you really want to get those Free Spins on Jurassic World.

This Microgaming slots game has 3 separate Free Spins games that are handed out randomly up to the 15th time. Roar into action and play in the Gyrosphere Valley, Creation Lab, and the Raptor Den, where you can get 10 spins in each.

If you do get to the Gyrosphere Valley, you will be greeted by the Multiplier Trail, which increases your multiplier on each losing spin! In the Creation Lab, you will play on Rolling Reels where winning symbols fall away and allow others to drop into place. This means you can put together some winning streaks and win big.

As for the Raptor Den, you will play with Wild Scatters, which means all Scatter symbols will be Wild until you get a Free Spin. Finally, the Indominus Rex feature is triggered when the dinosaur appears in front of the reels during a spin. In this bonus round, you can win up to 1000x your initial wager.

Avalon II

Avalon II is a sequel to the classic slot game Avalon and manages to be just as good, if not better, than its predecessor. Microgaming has taken inspiration from the legend of King Arthur and Avalon II is every bit as rich as the stories of Arthur, Merlin, and the Knights of the Round Table. To really showcase its theme, Avalon II has some of the best graphics of any online slot game.

As one of the best Microgaming slots, the game also has stellar audio effects and animations. Looking at the game, it has 5 reels and the 243 pay lines features. So, let’s get going on a magical adventure of magic, knights, and legends.

The Avalon II logo acts as the slot Wild symbol, replacing any other symbol apart from the Grail and the Lady of the Lake. Multiple Wilds can land across an active pay-line and can form wins without other symbols. Below are the core features of Avalon II.

Expanding Wild: The Lady of the Lake symbol acts as the Expanding Wild and will only ever land on the third reel. Once the lady does arrive, she will expand to cover the whole reel. Like the regular Wild, the Lady of the Lake does not substitute the Grail symbol.

Merlin Bonus: The Merlin Bonus can trigger randomly during the standard spin game and it will award a random multiplier.

Grail Bonus: Speaking of which, the Scatter symbol of Avalon II is the Grail symbol. If 2 or more of these icons land anywhere on the reels, it will provide a cash win. You want to see 3 or more because then you will enter the bonus game. Here you will move through the game world trying to find the Holy Grail. One of two paths are available, each featuring the following bonus games:

  • Lake of Legend – In this game, you will roll virtual dice to secure a random multiplier value. 10 dice rolls are offered, and the multiplier is awarded directly based on the number that appears on the dice. 6 sword fragments are available to find, each corresponding to a dice value. For example, if you roll a 4 and there are 4 sword fragments, the sword will move to the forge area. In the forge area, you can put the sword back together and receive a 15x multiplier.
  • Whispering Woods – Here you will select between shield symbol objects. Each object hides a random prize, such as a multiplier. 2 picks are available in this bonus round.
  • Misty Vale – This round will give you 15 Free Spins and the choice of using an extra wild multiplier to help with the spins. It is worth pointing out this wild will not act as a regular Wild and replace symbols. However, it will ensure all winning payouts are doubled for any combo.
  • Forest Falls – If you trigger Forest Falls, you will be able to spin 20 more times for free. Furthermore, the game logo will act as a Wild throughout the Forest Falls game.
  • Dusky Moors – This is a good old-fashioned selection bonus round where your memory will be tested as you choose objects. The goal is to match items from cards that are presented to you. There are 12 in total and you need to find 2 equal helms to win the game. Each match you make will result in a multiplier bonus that can move up to 8x your initial bet.
  • Morgan’s Keep – Triggering the Morgan’s Keep bonus game you will give you a combination of 20 free spins and Rolling Reels. These work across any game situation apart from Scatter wins. When you get a win, the winning symbol will explode and those above will fall into place. This means you can get some massive continuous winning runs. At the start of the game, the multiplier is 2x your bet but increases by 1x after every winning explosion, although up to a limit of 6x.
  • Hall of Shadows – Next up is Hall of Shadows, where you can choose fight methods for the Black Knight in an effort to win random bonus multipliers. Fights take place over 5 rounds and each round has five sequences you can choose combinations for.
  • Isle of Avalon – Finally, there’s the Isle of Avalon bonus game. Here you get to spin 4 wheels on a bonus multiplier. All of the wheels have sections with a multiplier value on them. Each spin from the centre out (wheel 1 in the centre). Wheel 4 has the largest multiplier but will only become unlocked when wheel 3 stops on 0.

Thunderstruck II

The last slot to make the list of the best Microgaming slots is Thunderstruck II. This 3D online slot is a classic amongst gamers and considered one of the best all-around slot games of all-time. Like the original Thunderstruck game, this slot is filled with stunning graphics and world-class gameplay. In the game, you will be immersed in the world of Norse mythology.

In the ancient city of Asgard, you will be walking among the gods Odin, Loki, and of course, Thor. Interestingly, despite the excellent theme, the reels cover the screens so there’s not a lot happening in terms of gameplay visuals. That said, the reels do look beautiful and the animations are wonderful to behold.

There are 5 reels alongside Microgaming’s 243 ways to win pay-lines. Action-packed gameplay is what Thunderstruck II is all about and in this game, you can pick up some massive wins. You get normal Wild symbols to replace other symbols on the reel and there is also a Windstorm feature, and a Great Hall of Spins bonus with four choices:

The Great Hall of Spins

In the Great Hall of Spins, you will be greeted by these four options: Valkyrie, Loki, Odin, and Thor.

  • Valkyrie: Arrives on the 1st Hall of Spins trigger and gives 10 free spins and a multiplier of 5x across all wins. You will also be able to re-trigger the Free Spins round in this bonus.
  • Loki: Will come into play on the 5th trigger of the Great Hall of Spins and will provide 15 spins alongside the Wild Magic bonus. When this symbol lands on the third reel it will turn other symbols into wilds at random. You can also win 4 more spins by re-triggering the Loki feature.
  • Odin: You have to trigger the round 10 times to see Odin come into play. The King Of Asgard will award you 20 Free Spins and also provide the Wild Raven symbol. With this symbol on your side, you will see symbols randomly transform into 2x and 3x multipliers. If both of Odin’s Ravens land at the same time, a 6x multiplier is awarded.
  • Thor: Finally, you will come to the God of Thunder himself if you trigger the Great Hall of Spins 15 times. Thor will give you 25 spins and Rolling Reels to help you stack up some wins with up to a 5x multiplier value.

Wildstorm – In Thunderstruck II, the Game logo acts as the Wild Symbol and replaces any other icon aside from the Bonus Mjolnir (Thor’s hammer). The Wildstorm feature triggers randomly and turns up to 5 reels wild.

Are Microgaming Slots Safe?

The simple answer is yes, but let’s explain why. As mentioned, Microgaming is one of the legends of the online gambling industry. The company has helped to shape the market, including the development of a framework to ensure safety. Microgaming was a founder of the e-Commerce Online Gaming Regulation and Assurance (eCOGRA).

This is the body that tests online games to ensure they are safe and have security to keep users protected. Furthermore, the eCOGRA helps to drive regulatory compliance, which means casinos and developers must adhere to specific standards. This can be specific codes of conduct in a territory they work in or a wider acceptance of regulations.

Microgaming uses its position with eCOGRA to ensure its games are only available at online casinos that meet these strict rules. For example, eCOGRA runs frequent tests to ensure Random Number Generators (RNGs) available on online slots are fair to players.

Microgaming and Other Slot Developers

Microgaming and Other Slot Developers

Microgaming is the oldest, biggest, and most established developer of online casino and slot software. However, the company is certainly not the only big player in town, and rivals like NetEnt, IGT, and NextGen Gaming compete with Microgaming in the slot market. Online slot players value the Microgaming name and associate it with the best online casino games based on two decades of experience.

That doesn’t mean you should ignore other major developers. For example, NetEnt has found its own particular niche in the online slot market by focusing on games with high-end concepts. The company uses a lot of licensing from movies and music to create complex 3D slots. While these may appeal to high rollers, Microgaming still tends to be more appealing to people of all skill levels.

Another standout feature of Microgaming is its versatility. The company has been developing online slots for so long that it has dozens and even hundreds of games available. That means you will be able to find a Microgaming slot that you love.
