Book of King Arthur Slot, Details & Wager Limits
The Book of King Arthur slot is played on a machine made up of 5 reels and 3 rows that combine to offer 10 paylines. Land 2 or more matching high value symbols or wilds on 1 of those 10 payline from left to right, starting from reel 1 to form a winning combination. You’ll need 3 lower value symbols on a line for a winner. It’s a very straightforward setup.
Stake sizes range from between 20p and £50 per spin. Click on the chip icon above the spin button and pick from the range of stake sizes. If you use the Boost feature, the max stake can reach £100 per spin. Autoplay lets you run 10, 25, 50 or 100 autospins.
The Book of King Arthur RTP is 96.1%. As with most ‘Book of’ slots, the variance is very high. It offers a 30.8% hit frequency rate meaning nearly a third of spins will give you a winning combination. The max win is 5,000 x your total stake per spin.
Theme – Audio and Design features – Arthurian Legend
The design in the Book of King Arthur slot is nicely done. With an Arthurian legend theme, the interior of Camelot Castle forms the backdrop to the reels. The visuals here are simple but nicely drawn.
There’s a mediaeval-style soundtrack playing in the background while you spin that fits the Arthurian theme nicely and creates just the right level of atmosphere. This is a simple yet well-designed slot.
You’ll see colourful A to 10 royals spinning around the reels alongside a shield, a grail and the famous sword, Excalibur. The bearded King Arthur is the most rewarding symbol, paying 1, 10, 100 or 500 x your total stake if you land 2, 3, 4 or 5 on a payline. The other symbol is the Book of the title. We’ll look at this symbol’s magical properties below.
You can play Book of King Arthur on desktops, tablets and smartphones. The classy sound and visuals and simple gameplay work well in the Book of King Arthur mobile slot. It’s very playable, even on a smaller screen.
Book of King Arthur Bonus Features
There are few more classic slot themes than King Arthur. Just for the Win has added a classic bonus feature to match. The main attraction is the Free Spins feature that delivers free spins complete with expanding symbols. Pay extra to bring the Boost into play which adds expanding wilds to the mix in both the base game and the free games.
Free Spins feature
The Book symbol serves a dual role. It’s a wild and substitutes for all the standard symbols when it makes up part of a winning combination. The Book is also a scatter which can trigger the game’s Free Spins feature. Land 3, 4 or 5 Book symbols on the same spin and you’ll first trouser an award equal to 2, 20 or 200 x your total stake. You’ll also activate the Free Spins with 10 free spins.
Before the feature begins, a wheel spins. The symbol that lands next to the pointer becomes the special expanding symbol. Each time this symbol lands during the free spins, it will expand to fill the reels if the expansion leads to the creation of a new winning combination.
The max win per free spin depends on which symbol is the special expanding one. The higher the value of the symbol, the bigger your potential payouts. Here’s how much you can win if you fill the reels with the same symbol:
| Symbol(s) | Max Win |
| Q, J, 10 | 100 x stake win |
| A, K | 150 x stake win |
| Shield, Grail | 750 x stake |
| Excalibur | 2,000 x stake |
| King Arthur | 5,000 x stake |
The expanded symbols don’t follow traditional paylines when it comes to payouts either, they pay scatter style. For example, landing matching expanding symbols on reels 2, 4 and 5 would still lead to a winner being created with a payout to match. Finally, unlimited retriggers are possible for more free spins.
In some territories, you’ll have the chance to buy the Free Spins feature. This costs 80 x your total stake. You’ll then play 10 free spins. Known as the Buy Free Spins feature, it isn’t available if you have the Expanding Wilds Boost active (see below).
Boost feature
Enable the Boost feature and it increases the size of your stake by 100%. In return for that higher stake, you’ll bring expanding wilds into play. Whenever a wild symbol lands, it fills the whole of that reel. These are in play in both the base game and the free spins. This makes it easier to achieve bigger winning combinations.
Book of King Arthur Review Summary – a straightforward take on a classic theme
Just for the Win’s take on the classic Arthurian legend is a simple one. The game engine and the features are very straightforward. Basically, the Book of King Arthur slot is a ‘Book of’ game like Play ‘n GO’s Book of Dead or Novomatic’s Book of Ra Deluxe.
They difference from Book of slots is the Boost feature which gives you expanding wilds. This isn’t a cheap option though, so proceed with care. The key to winning big is to get a high value special expanding symbol – it’s that simple.
I’ve played free spins with expanding symbols in plenty of other slots (usually with an Egyptian theme). Book of King Arthur might not be overflowing with originality but it’s a playable version of a popular theme. A better option is Lord Merlin and the Lady of the Lake by Play ‘n GO which offers the same free spins feature but with 10,000 x stake wins per spin.
