Book of King Arthur Main Features
In this 2021 slot game release by software game developer Just for the Win in collaboration with Microgaming, we are presented with a colourful reel setup. With the opportunity to win up to 5,000x your stake, the Book of King Arthur slot also goes on to prove that the online gambling industry just cannot get enough of the Book Of slot series.
Slot Layout
The Book of King Arthur slot game has a basic set up of 5 rows, 3 rows and 10 fixed paylines. To form any winning combination, you would need two or more high-value matching symbols on one of the 10 paylines starting from the left and going in the right-hand direction. You can also achieve wins if you have three low-value matching symbols.
Graphics and Sounds
The game is set against a golden background with large columns flanking the reels. The reel setup is also bulging outwards as if it is in 3D format. This may be an Arthurian legend-themed online slot game, but it has been done majestically. There is also a medieval-style soundtrack belting in the background to set the atmosphere.
Gameplay Features
In terms of in-game features, there is a free spins bonus round where you immediately receive 10 free spins, expanding wilds and the option to buy your way into the free spins bonus round. All of these Book of King Arthur slot bonuses will be discussed in more detail within this slot review.
Book of King Arthur RTP
The Book of King Arthur slot RTP stands at 96.1%, which is the average payout percentage for most online slot games available on the market. It is a very volatile slot game, so if you are looking for small yet frequent wins, this game is not it. If you love highly volatile slot games, keeping an eye on your bankroll would be wise.
Book of King Arthur Variance
The Book of King Arthur slot game also comes with a hit frequency of 30.5, which means that a third of all spins carried out can result in a winning outcome. The maximum win that can be achieved in this game is 5,000x your stake. This can only be achieved by filling the entire reels with King Arthur or wild symbols.
Book of King Arthur Special Symbols
There is a few symbols available in the Book of King Arthur slot game, with some having a special function and role within this game. As you can assume, there is a mix of playing card symbols as is customary with most online slot games as well as symbols that are related to the theme.
- The lowest paying symbols, include the number 10, Jack, Queen, King and Ace, which pay between 10x and 15x your bet for five identical symbols on a payline.
- Next, you have the shield, the chalice and the sword, which pay between 75x and 200x your bet for five symbols on a payline.
- The most valuable symbol is King Arthur himself, which pays a whopping 500x your bet for five symbols on a single spin.

Book of King Arthur Bonuses
Software game developer Just for the Win has added a few in-game bonus features to make this game interesting. Here are the features available in the Book of King Arthur slot game.
Free Spins Bonus
The Book symbol acts as both the game’s wild symbol as well as scatter. As a wild symbol, it replaces other symbols in a bid to create a winning combination. If you land three or more book symbols on a single spin, then you will receive between 2x and 200x your bet as well as an entry into the free spins bonus round.
- You will immediately receive 10 free spins. Before the free spins bonus round kicks off, a symbol will be randomly chosen to act as the game’s expanding symbol.
- Each time this symbol turns up on the reels during the free spins bonus round, it will expand to cover entire reels creating more winning combinations.
- The symbols in the free spins bonus round carry out bigger payouts, especially as expanding symbols that cover all the reels.
The payout for all of these symbols if you fill all the reels is as follows:
- The Queen, Jack and 10 pay 100x your stake
- The Ace and King pay 150x your stake
- The Shield and the Chalice pay 750x your stake
- The Excalibur sword pays 2,000x your stake
- King Arthur pays 5,000x your stake
It should also be noted that expanding symbols do not follow the conventional payline structures. If you land matching symbols, on reels 1, 3 and 4 for example, you will still achieve a win. Furthermore, you can still retrigger more free spins during this round by landing three or more scatter symbols.
Buy Bonus
You have the option to pay for your entry into the free spins bonus round by paying 80x your stake, thanks to the Bonus Buy feature. When doing so, you will skip the action in the base game and you will immediately receive 10 free spins. The Buy Bonus feature is not available if you have the Expanding Wilds Boost active.
Boost Feature
You have the option to bring expanding wilds into play enabling the Boost feature, which increases the size of your bet by 100%. Each time a book wild symbol lands on the reels, it will expand to fill the entire reel. This option is available in both the base game and the free spins bonus round.
Book of King Arthur on Mobile
Game provider Just for the Win is a modern software game developer and thus has created the Book of King Arthur slot game with a mobile-first approach. The game was created using the latest advances in technology to make it fully optimised and responsive to work on any device.

All of these casinos offer welcome casino bonuses, including exclusive deals and offers. Here are our takeaway points for Book of King Arthur from Just for the Win.
- The Book of King Arthur slot game is a very straightforward online slot game, which is similar in nature to many other Book of game series created by other software game developers such as Play ‘n GO. This is a classic theme but one that is often explored by many game developers. It has enthralled and captured the imagination of players for years.
- The Boost feature adds expanding wilds in the base game which can prove rewarding. Granted, it will cost you a bit and failing to keep an eye on your bankroll can prove to be a costly mistake. It would have been nice to know what the effects of the Boost feature are on this online slot game’s payout percentage.
- If you succeed in filling the entire reels with King Arthur or book symbols, then you are guaranteed the maximum win of 5,000x your bet. Overall, the Book of King Arthur slot is a nice welcome addition to the online gambling market, even though the industry is a little saturated with book-themed slot games.
