Mighty Arthur is powered by Quickspin and has 5 reels and 20 paylines. Playable from 20p to £100 a spin on desktop, mobile and tablet devices, this fantasy themed offering benefits from expanding wild symbols and random wilds which apply in the base game and Free Spins Bonus feature. Join King Arthur and his sorcerer Merlin on a quest for wild wins. Mighty Arthur – looks superb for starters. The bonus features are good but don`t expect to trigger them too often. Despite that, I found it to be a medium variance offering maximum payouts of 621 times your stake on each spin. If you like the theme and something more volatile, I highly recommend WMS` Black Knight II which offers you up to 3 sticky wild reels in the feature.
