Where To Play Mighty Arthur by Quickspin

All Sites are UK Licensed UK


Quickspin slots are all about the Wilds, and if you’re a fan of games like Pied Piper or Rapunzel’s Tower then chances are you will enjoy a few spins on Mighty Arthur too.

The story of King Arthur is an old English myth that mixes medieval history and fairytale legend, and it’s just the sort of fantasy that Quickspin bring to life in their best slot titles.

This one should appeal to pretty much all players as it gives reasonable payouts throughout the base game – where the Wilds are always your keys to riches – and also delivers some pretty tasty action via the Free Spins round, which may be difficult to trigger, but has great potential.

Some Key Facts About Mighty Arthur

  • This is a 20 fixed payline slot with 5 reels. It pays out from left to right.
  • The highest value symbols are characters and objects form the tale of King Arthur – the cup (4x for five in a row), a spell book (4x for five in a row), King Arthur (6.25x for five in a row), and the  b
  • Lower value symbols are 10 through to the Ace (2.5x for five in a row).
  • The Wild which substitutes for all others except the Bonus Symbol pays out 7.5x for five in a row.
  • The key to big wins is the Mighty Arthur Wild that FULLY occupies the middle three rows giving you GUARANTEED WINS! It pitches in both the base game and the bonus round.
  • There is also a Merlin Wild that creates 2 to 6 new Wilds across the reels.
  • Mighty Arthur can be played from 20p up to £100 per spin.
  • Comes with an awesome soundtrack!

Mighty Arthur – How It Works

Mighty Arthur Slot

During the base game look out for the character symbols – the King himself and the beautiful Queen are high payers, as is the Wild symbol if you can land five in a row.

There are also the two Wild Features to wish for:

Arthur Expanding Wild – When the Arthur Wild lands anywhere on the middle reel during either the base game or the bonus round it will expand to the adjacent reels, creating one almighty 3×1 wild that guarantees wins.

Merlin Random Wilds – The sorcerer Merlin can weave some pretty clever spells himself. He is a rare site, but when he does land as a 3×1 symbol on any reel, he will turn between 2 and 6 other symbols on the reels wild as well. Land multiple Merlin’s and you can turn ALL symbols wild for a top payout.

10 Free Spins With Wild Features!

The Free Spins Round itself can be triggered by landing three or more Bonus symbols anywhere on reels 1, 3 and 5. This grants you 10 free spins. 

Of course, when the Free Spins are in motion you can also land both the Wild features active during the base game which gives you more chances for those big wins. Ideally you’re looking to activate the Merlin Wilds across multiple reels.

NOTE: the Free Spins round cannot be reactivated – once your 10 are up you return to the base game.

How To Win At Mighty Arthur

Like all slots, every spin here is a random event, and there is no magic formula to winning at Mighty Arthur – although Merlin’s magic tricks are a useful starting point! This is our five-point guide on what to look out for to help you find those winning spins.

  1. GOING WILD with Merlin’s Random Wilds – The sorcerer needs to cast some spells if you’re really going to win big – the best jackpot chance comes when he lands on three reels at once – that can turn EVERY symbol into a wild.
  2. Long Live the King – The hero of this story is where it’s at because you are GUARANTEED a win when he pitches on the middle reel. 3×1 symbols are unusual in video slots and it is a good reason to play this one.
  3. 10 Free Spins – Sit Back and Enjoy – The Free Spins round may not have a re-trigger but because it comes with both Wild Features you can still notch up a massive win within 10 goes. 
  1. Pick Your Stake Carefully – Remember to pick your bet size carefully based on your bankroll. This game is medium variance and should give you fairly regular wins, but if it’s not working out, don’t push it – take a break and come back later. Don’t chase your losses or up your stake!
  2. Try a Quickspin Slot Site – Pick from our list of UK-licensed slot sites with Quickspin games. We’ve chosen and reviewed the very best for you to enjoy. Or check out our dedicated slot page – the best slot sites UK


Mighty Arthur was released in October 2017 and fast became a favourite amongst Quickspin fans. It has all the features of their best games – beautiful artwork designed around a cool theme that mixes fantasy, mythology and history. It also is chock-full of Wilds, stacked and just waiting to deliver payouts.

Whilst the Free Spins round is pretty hard to trigger that isn’t an issue here because the two Wild features in the base game give you some great win opportunities there as well. And if you do make it to the bonus round, they are active there as well.

If you like this game, you might also like NetEnt’s slot, Asgardian Stones, or Gem Rocks by Yggdrasil.
