The legend of King Arthur has inspired poets, novelists, songwriters, artists and, yes, in recent years, even casino game developers. In the case of the online slot, Book of King Arthur, created by Microgaming and Just For The Win, the mythical monarch takes centres stage once again in a handsomely designed online and mobile casino game – because naturally, it’s been optimised for all compatible desktop, tablet and mobile devices.

Featuring Free Spins, a Boost Mode with Expanding Wild feature, stellar graphics and more, Book of King Arthur takes on a popular theme and delivers a crowd-pleasing result. Available to play at Royal Vegas Online Casino Canada, this mobile friendly game takes inspiration from some rich source material. In this review, we’ll take a closer look at what it has to offer.

Ready for some medieval action? Let’s go!

Design And Basic Gameplay

A visually appealing online and mobile casino slots game, Book of King Arthur is played across 5 reels and 10 paylines. The interior of King Arthur’s castle, Camelot, forms the backdrop to the reels, while a medieval-themed soundtrack can be heard while one is spinning.

The game has a percentage payout rate of 96.15% when the Boost mode is enabled and 96.10% when it is disabled – while the total hit frequency rate is between 30.80% and 33.04%. The maximum win is 5000 times a player’s wager per spin.

When it comes to bet sizes, the maximum and minimum amounts when the Boost Mode is enabled are set at 100.00 and 0.40, respectively. When Boost Mode is disabled, the minimum is 0.20 and the maximum is 50.00.


Book of King Arthur is an attractive online slot with symbols that complement the theme. The low-value symbols are the usual royals, A, K, Q, J and 10, each one minimally designed and given a different colour.

Then we have the more thematically relevant symbols, such as the grail, shield, and the legendary sword, Excalibur. A bearded and crowned King Arthur is naturally the most valuable symbol, able to pay out 500 times a player’s stake if 5 of a kind land. We also have the Book symbol, which acts as both the Wild and Scatter symbol. This means it can replace other symbols to complete winning combinations, plus it’s the key to activating the coveted Free Spins feature.

Free Spins

If one lands 3 or more Book symbols, 10 Free Spins will activate. Before the Free Spins begin, a symbol is chosen at random to act as a Special Expanding Symbol. Each time it lands during Free Spins, it will expand to cover the reels if that expansion resulted in a winning combination. This symbol does not need to appear on adjacent reels or on the first reel to complete winning combinations – it expands if it completes a winning combination according to the paytable.

Boost Mode And Expanding Wild

Book of King Arthur can either be played with the Boost Mode enabled or disabled. By enabling it, players increase their bets by 100%. What’s more, the Expanding Wild feature comes into play. So, whenever a Book symbol lands on the reels, it expands to cover the entire reel. In addition, the Expanding Wild is active during both the base game and Free Spins, boosting one’s chances to score winning combinations as a result.

Feature Buy

Another interesting feature is the Buy Free Spins. Here, 10 Free Spins can be purchased for 80 times the player’s current bet. But remember, if Boost Mode is enabled, the Buy Free Spins feature cannot be activated.
