What does John have to say?

It’s not going to be a memorable ‘book of’ game, but the fresh theme, uplifting soundtrack and a couple of extra features make Book of King Arthur a very playable slot.

Book of King Arthur Review

Set in the medieval times, Book of King Arthur is a 5-reel, 3-row and 10-payline ‘book of’ slot from Just For the Win and Microgaming.

It has the classic free spins feature with expanding symbols, but there’s still something different about the game. For starters, the theme isn’t inspired by Ancient Egypt anymore but rather ties in nicely with the legendary King Arthur known for defending Britain from Saxons in the late 5th and early 6th centuries.

Another twist is how the special symbol is selected, plus you have a Boost mode, which brings expanding wilds into your play. But is it different enough to compete with the existing ‘book of’ favourites? One way to find out is to keep on reading our slot review below.

Book of King Arthur Bonus Features

With expanding symbols as the main attraction in the free spins bonus round, you’re looking at another ‘book of’ type of slot. But it’s good to see that it offers a slightly different approach to the overall gameplay.

For a change, it’s not the book but a fortune wheel that chooses a special expanding symbol, and there’s also a Boost feature that adds some new flavour to this well-worn game category. Let’s take a closer look at how to play it.

Wilds & Scatters

The book of Arthurian legends in this slot serves as both a wild symbol and a scatter. As a wild, it contributes to a winning combination by substituting for other symbols. As a scatter, it activates the free spins round and awards a payout of 2x, 20x, and 200x your stake for 3, 4, and 5 scatters, respectively, regardless of where they land on the reels.

Free Spins

You’ll need to land at least 3 scatters to access the bonus round and trigger 10 free spins. But first, a fortune’s wheel will select any symbol, except the book, to perform as a special expanding symbol during the free spins bonus round. If it can form winning combinations, the chosen symbol will then expand to fill all positions on the reels.

The good thing is that these special symbols follow the scatter pays mechanics, and don’t need to be adjacent to complete a win. More so, premium symbols pay for only 2 of them appearing on the reels. Finally, landing a further 3 scatters during this round awards an additional 10 free spins.

Boost Feature

Before each game, you can enable the Boost mode, which doubles your initial bet but brings additional bonus features to the gameplay – expanding wilds. The benefit here is that each time you land a wild, it will expand to a 1×3 size symbol in both the base game and the free spins round, allowing you to complete more winning combinations.

Book of King Arthur Jackpot

A Jackpot isn’t where the riches lie in the Book of King Arthur slot. It’s in the free spins bonus round where reels filled with the King Arthur symbol results in a 5,000x your stake max payout.

RTP and Volatility

Accompanied by high volatility, the game’s RTP is set to a neat rate of 96.10%. Don’t expect to land easy wins, but occasional big rewards are possible here.
