Do battle with the Mighty Black Knight in this 5 reel, 10 to 100 payline, middle ages themed video slot. Created by Barcrest, it comes with expanding wilds that expand the reels to offer 100 paylines. Also on offer are free spins and Big Bet Mode where sticky wilds and high value symbol only spins can be added. Play on your desktop, tablet or mobile device from between 10p and £250 per spin. The higher your stakes, the better the RTP rate on offer. This starts at 94% at minimum but can rise to 98% if you play at more than £4 per spin.

The action here takes place within the walls of a medieval castle. Joining the lower value playing card suit symbols are orbs, rings, maps and crowns. Best of all are the king and queen – land 5 of his majesty and you’ll pocket an award equal to 5 times your total stake.

Helping you to create those winning combinations is the Black Knight wild – if you land this fully stacked in the base game, it will open up the expanded reel set and with it 100 paylines. The wild fills the whole of the newly expanded reels. This is known as the Mighty Reels feature.

The main feature offering here is a Free Spins feature which is triggered by landing 3, 4 or 5 of the Black Knight’s shield – you’ll then receive 8, 12 or 20 free spins. Rather than having to land a fully stacked Black Knight wild to open up the expanded reels, landing any part of the Black Knight does the trick. Landing 3, 4 or 5 scatters awards another round of 8, 12 or 20 free spins.

If you want to spice up your action (and have the bankroll for it), you can opt to play in Big Bet Mode. This is a series of 5 linked spins. Pay £20 and you’ll get the expanded wilds when any part of the Black Knight wild hits. At £30, you’ll get the expanded wilds plus all of the lower value playing cards are removed. For £50, you’ll get the expanded wilds plus the lower value playing cards removed. Any wild that hits is locked in for the duration.

If you’ve played Barcrest video slots before, you’ll have a pretty good idea of what to expect here. Both the design and gameplay are perfectly solid without offering anything too imaginative. The Big Bet Mode can certainly up the action. It’s certainly not a cheap action so consider your bankroll carefully.

If you enjoy the medieval theme or are a fan of Barcrest games then Mighty Black Knight should offer plenty of appeal. If you like the original titles from WMS, Black Knight and Black Knight II, I’m afraid Mighty Black Knight doesn’t come close.
