Available across all Android and iOS-powered mobile devices, Book of Arthur is a slot that you can play in just a few taps. You can see the reels on the centre of the screen, the setup buttons on the right and the Bonus Buy/Boost buttons on the left.

The Play button is the largest and going up, you'll see the bet configuration button. You can place a bet that goes from 0.20 to 100 credits per spin at the best online casinos. Next, you have the Autoplay button, followed by the three-dot button. This is where the paytable is. Inside, you’ll see the mediaeval-styled playing card Royals from 10 through A, followed by the high-paying Excalibur, Shields, Grails and the King himself, which can deliver prizes from 75x to 500x the stake. You need to land at least three low-paying, or two high-paying symbols to form a win.

At the bottom of the screen, right below the reels, going left to right, you’ll see the Balance, Total Win and Bet displays.

You should know right away about the Boost feature, which actually enhances the bet level. While the default bet level is from 0.20 to 50 credits per spin, you can double the level by enabling the Boost feature, and you’ll be able to place bets from 0.40 to 100 credits. What will you get with that? Well, the Wild which normally appears in a standard 1x1 size, will start appearing in 1x3 size, covering the entire reel it lands on.

The Wild, on that note, can replace any regular symbol in the formation of a winning combo. This is the symbol presented with the dragon-covered Book. The Wild also acts as Scatter when needed to trigger the bonus round. You need 3 or more Scatters to grab 10 Free Spins. In addition to triggering the bonus game, this symbol delivers 2x, 20x or 200x the stake, for 3, 4 or 5-symbol combos, respectively.

Suited to the theme, when you trigger the Free Spins, you’ll see a round table spinning to choose a special Expanding Symbol at random, which will appear during the bonus round. If this special Expanding Symbol completes a win, it will expand to cover all positions on the respective reels. This symbol, by the way, pays on any reel, regardless of whether adjacent or not. The Free Spins can be retriggered if you manage to land 3 or more Books on the reels.

If you don’t wish to wait for the Books to land in the first place and you’d like to take a shortcut to the Free Spins, you can pay 80x the stake and activate the Bonus Buy feature, which will deliver at least 3 Books on the next spin. But, if you’ve enabled the Boost feature before, you cannot purchase your way into the Free Spins as you cannot place the Bonus Buy bet.

As introduced, Book of King Arthur is a slot that can deliver 5,000x the stake max win. This means that if you place the max bet of 100 credits, with the Boost feature activated, you could scoop 500,000 credits, which is not bad at all.

Considering its high volatility and decent 96.10% RTP, this is, indeed, a rewarding slot, which can deliver huge payouts when you least expect it. Add to that the fact that it actually delivers wins with a hit frequency of 30.80%, and you’ve got yourself the formula for winning! Therefore, make sure you place the right bets to get the most out of it!

This would put you at a significant advantage, and help you boost your wins even further.
