Two fairly popular angles are being pursued in the latest Microgaming and Just For The Win collaboration, a slot called Book of King Arthur. It’s obvious, that the theme of choice is the legend of King Arthur and of Camelot, but at the same time we’re getting a Book-style game, with all the features, volatility and handsome rewards that are typically associated with the genre.

Book of King Arthur doesn’t surprise with its layout, you get the usual 5 reels & 10 lines which are common for its category, and the 5,000x top payout is standard as well. 96.10% is the Return to Player that’s expected, while on the list of special features we discover the mixed scatter/wild, free spins, expanding wilds, so pretty much all the options you’d want.

Betting and Prizes

$0.20 to $50, this is the complete betting range that you can use when you’re playing Book of King Arthur, with its 10 active lines.

In addition to the regular wager, you also have the Boost option, which requires an extra amount per spin, but it will also add expanding wilds to the game.

A 5,000x jackpot sounds good, but it’s the same amount that you get from 99% of the Book-style slots, so it doesn’t really add anything. These are mostly high volatility online slots as well, so there is risk to go with that big potential.

On the other hand, long-term the RTP is where it should be, at 96.10%, so slightly above average.

Book of King Arthur Slot Features

Though it brings the King Arthur theme to the Book category, this slot doesn’t do a lot of things differently. You will encounter all the usual options, and it all starts with the Book symbol.

Book icons are to be used as both scatters and wilds. As a wild symbol, it will contribute to any new winning combinations which will form on its lines. It’s a replacement, and it will have a major influence in the long run.

At the same time, you also get to use these Books as scatters, so having them landing anywhere between 3 and 5 times in a single spin gets you a prize (up to 200x the stake) and 10 free games.

Next, you will get a random symbol to become special, which gives it the ability to expand during free spins, and then to form winning combinations wherever it may show up, even on non-consecutive reels. If King Arthur is the special symbol, and he lands just once on each of the five reels, it will expand and cover all lines, paying 5,000x the stake (500x per line).

If you choose to use the Boost option, you will play with double the wager, but you also get expanding wilds, both for paid and free rounds. They still count as one scatter on each reel though.

Theme & Design

Book of King Arthur does what it promises, and it offers us a Book-style gameplay, in the universe of Camelot’s ruler. King Arthur is shown in the game, but no other characters are included. In addition to the Book (wild/scatter) and King Arthur (top symbol), the others show Excalibur, the Holy Grail, a Shield and the top five Royals (10 to A). Not a very good looking design, but it works well enough, if you want a distraction from the usual Egyptian slots that constitute the vast majority of titles in the Book category.


Book of King Arthur slot could be a solution for the fans of the genre, provided that they’re OK spending twice as much per spin, to use the Boost option and its expanding wilds. There are no other major differences to make it more interesting in this overcrowded part of the online casino industry.
