How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

Book of King Arthur is the latest ‘Book Of’ slot this time from Just for the Win using the mysterious and romantic Arthurian legend as the theme. Those who enjoy classic slots like Book of Dead, or more recent games from the genre like Nolimit City’s fabulous Book of Shadows, will enjoy this game that follows the classic gameplay and high variance model. The action is introduced by Medieval-style music while the background can just be seen around the 5-reel 3-row layout with stone pillars and a red carpet, bringing to mind the interior of a castle.

The red and gold colour scheme is suitably regal and the metallic border on the reels reminds us of armour. It has a simple layout with its barrel-shaped reel design feeling almost 3D. In keeping with the other ‘Book Of’ slots, this game relies heavily on Expanding Symbols and Free Spins for its biggest winning opportunities.

You’ll be able to play at online slot sites in the UK from April 201.

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

This slot has a 20p minimum bet and an average RTP of 96.1%, while the high volatility means you can expect a bumpy ride with peaks and troughs in payouts. This makes Book of King Arthur best suited to players who enjoy risky gameplay, and those who have ever sat frustrated at Play n Go’s Book of Dead and it’s vertiginous volatility will know what we are talking about here! Tread carefully and choose a stake to fit with your bankroll if you choose to take this game on.

The good news is there is an enticing top payout of 5,000x stake to play for if you manage to find a screen filled with King Arthurs, something which is possible in the all-important free spins round where special symbols are guaranteed to expand to full reel height when they land. More on that in a moment.

Symbols and Paytable

Our Score 8

The symbols in Book of King Arthur include the King himself, his sword Excalibur, a book, goblet and shield. The best paying symbol is King Arthur and he can award 500x stake if you find 5 matches on a payline. The other premium symbols pay from 75x stake for 5 of a kind, while the high cards award the lower payouts.

The book symbol is the Wild and Scatter combined and this has the power to launch the Free Spins round. The book also provides a payout of its own with up to 200x stake available for 5 of a kind landing anywhere on the reels.

Features and Gameplay

Our Score 7

There is nothing experimental about the features and bonus round in Book of King Arthur. This game delivers exactly what you would expect in that respect, with all the fun loaded into that free spins round. Here is how it all fits together:

Book Wilds/Scatters

The book symbol is both Wild and Scatter. This means it substitutes for other symbols to create more potential winning combinations, while also triggering Free Spins when 3 or more land on the screen. The book also awards a payout of 2x, 20x or 200x stake when 3, 4 or 5 appear anywhere on the reels.

Free Spins

Landing 3 or more books will trigger the Free Spins round with 10 Free Spins awarded initially. Before the round begins, a round table spins to reveal which icon will become an Expanding Symbol. This can then expand on the reels to cover every position, working across all paylines and reels. If you hit 3 or more books during Free Spins, the round will re-trigger.

Boost Feature

In regular play, the minimum bet is 20p but if you activate the Boost Feature, this increases to 40p. Doubling the bet in this way causes the Wild to expand to cover the whole reel and increases your winning chances on every spin.

Bonus Buy

In some countries (check the information screen in the game for details) you have the option to buy your way into the Free Spins round instead of waiting for it to trigger in normal play. This will cost you 80x your bet and guarantees at least 3 book symbols on the next spin.

The Final Verdict

Our Score 7.4

Book of King Arthur is an atmospheric slot that will please fans of Arthurian legend and medieval themes. Although it’s a simply-designed game, there are some intriguing bonus features. The Bonus Buy is a good idea if you’re after the bigger payouts, considering the Free Spins round is where you’re likely to hit a screen filled with King Arthurs. However, the top payout of 5,000x stake isn’t great compared with other ‘Book Of’ slots that use Expanding Symbols, such as Book of Shadows with its 30,000x stake jackpot. This is a game that favours the higher roller with the Bonus Buy and Boost Feature both costing extra pennies, while the high volatility and 20p minimum bet will be tricky for low rollers. It’s enjoyable for few spins whatever your pocket size, so if you appreciate the medieval vibe, it’s worth trying your luck on Book of King Arthur.
