Play Mighty Black Knight for Free

Once upon a time, there were two noble online slots developers called Barcrest and Williams Interactive (WMS). Both conquered everything they saw in their respective domains. But then something dramatic happened: the two rivals were bought out by a bigger king calling himself Scientific Games (SG Gaming). The two brothers now occupy the same castle, releasing online casino games under the same banner.

As a result, Barcrest and WMS's slots are beginning to look the same. And where WMS were known for their Colossal Reels range of online slot games, Barcrest has Mighty Reels. It's where Mighty Black Knight comes in here. The layout is similar to WMS games like the music-themed KISS slot machine or Giant's Gold and the symbols akin to the Spartacus Gladiator of Rome slot game.

In terms of coins, Mighty Black Knight punters place a set stake across the whole 5 reels. Bets range from 0.10 to 250.00. It can certainly be worth pumping up the stakes a little as stacked symbols and stacked wilds can regularly appear.

Paylines vary depending on how much you bet. At 0.10 only 10 win lines are in play. At 0.20, 20 lines play, and so on. Bets of 0.50 and above brings 50 paylines into play.

The game also includes a 'Big Bet' feature. By clicking the BB symbol you can automatically select 5 bonus spins to enjoy. For 20.00 the player wins 'Mighty Reels' with stacked and expanding wild symbols (the knight). For 30.00, the same feature applies but all royal symbols (clubs, diamonds, hearts, spades) are removed.

Finally, 50.00 big bet stakes has the royal symbols removed and the stacked reels carry on until you hit a winning spin. With this, the whole 100 paylines are activated as the portcullis rises. Any wild symbol appearing will also trigger Mighty Reels. Regardless of your stake, your paylines will double when Mighty Reels comes into force.

A big tip from us is to check the paytable for the list of payouts first before you play. There are two sets of payouts in the Mighty Black Knight online casino game. One set is for the Standard Game and another when playing the Big Bet game. The Big Bet prizes are worth double.

In the regular game, the low limit poker symbols pay from a tenth to 1x your total stake when landing 3-5 of a kind. Various medieval artefacts come next. The gold ring and map pay 1/10 to 1.5x, the crown and orb pay 1/5 to 2x, but the king and queen in this medieval land pay the best. The queen pays 2/5x your total stake and 4x for 5OAK. The king pays out 1/2x for 3OAK and 5x for the jackpot.

Look out for the gold knight chess piece. This bonus scatter symbol triggers the free spins round. Three scatters triggers 8 free spins, with four symbols triggering 12 free spins and five symbols 20 free spins. You can also add on extra free spins by landing further scatters.

Watch out for that portcullis, though. The free spins round always starts with the portcullis down. There's no opportunity to lift the portcullis with Mighty Reels here. However, wild symbols will still expand if in view on the reels.

If you love the cut of Barcrest's Mighty Reels jib, check out the aforementioned Colossal Reels games from WMS. Elsewhere, Aussie gambling outfit Ainsworth are on to a winner with their Flying Horse slot.

And if you like the idea of reels that increase to include more paylines, check out another Ainsworth slot - Rumble Rumble. During the free spins feature, the existing reels expand to nine positions for added fun.

You can try out the free Mighty Black Knight slot now. It's got lots of medieval action, and the volatility is pretty big. We found it was worth testing out the Big Bet feature once or twice just to test the volatility. But even without it the game can have some wild swings up or down.

The animation on the expanding wild symbols is good in this game, and the sound FX top-quality when not being too scratchy. Grab your lance and see how much you can win.
