Book of King Arthur Slot Review

A "Book of…" clone that does things a bit differently, Microgaming’s Book of King Arthur is a great adventure in its own right. The slot was developed exclusively for the Isle of Man studio by JustForTheWin, a frequent Microgaming collaborator. It comes with 5 reels and 10 fixed paylines where you’ll be going on an age-old adventure spiced up with some Book of… tricks.

The slot is based on the well-known Arthurian legend and the Camelot Castle in the background. The Book of King Arthur slot has a relatively easy learning curve and a pretty solid appearance. King Arthur himself leads the charge on the reels, also acting as the titular Book symbol.

Play the Book of King Arthur slot for real money at one of our top online casinos and enjoy a great "Book of…" adventure with a twist!

Book of King Arthur Slot Setup and Controls

Microgaming slots always look great. The Book of King Arthur slot is no exception from that rule. It’s a nicely designed slot with a familiar layout and all the controls laid out in front. The reels are framed in inlaid metal as befits a slot based on the Knights of the Round Table.

In the background, you can see parts of Camelot Castle. The graphics and symbols look sharp. In terms of payouts, Arthur pays the most – 500x your stake for five of a kind. This is also the Book symbol that has magical properties we’ll talk more about later.

All of the action is followed by a great soundtrack that perfectly fits the theme. Overall, the Book of King Arthur slot game is nicely designed and very easy to spin.

How to Play the Book of King Arthur Online Slot

To start the Arthurian adventure, you will need to invest some coins. Prudent players will dip their hands into the online casino's coffers and choose one of the best slot bonuses available to start off the adventure. Once your coin bags are ready, you need to set your bets. You can go as low as 0.20 and as high as 50.00 per spin. As soon as you hit the Spin button (or use Autoplay), you’ll time-travel to Camelot in a second.

The action takes place on a 5x3 grid with 10 fixed paylines. In the base game, you will need to match identical symbols from the left to the right to form winning combinations. At least 3 low or high-paying symbols are needed on a line for a winner, so even new players shouldn’t have trouble spinning the reels.

Like with most Book of… slots, there are no special features available in the base game. You’ll be relying on the Book symbol and its dual wild-scatter properties to form winners. On the left side of the reels, you’ll see a Boost feature that bumps up the stake to 100.00 per spin. It also adds expanding wilds to the reels in both the base game and bonus round.

Right on top of it is the Buy free spins feature that costs 80 times your wager and takes you right to the free spins round.

Book of King Arthur Slot Free Spins

If you don’t buy your way into the bonus round, you can land it via the Arthur (Book) symbol. Three of these symbols will scatter pay instantly (2x for 3) and give you 10 free spins as well. Four or five Arthur symbols pay 20x and 200x respectively.

Before the free spins feature begins, a wheel will spin on the screen. This will give you the expanding symbol – it’s the one the pointed lands on. Every time this Wild lands on the reels, it will expand to cover one, increasing your chances to win solid sums of cash.

The higher the value of the expanding symbol, the bigger the payouts. If you’re lucky for the wheel to stop at King Arthur, the slot will reach its winning potential. An added plus of the expanding wild is that it pays Scatter style instead of following traditional symbol payout rules.

You can retrigger the Free Spins Round infinitely as long as you land more scatters.
