As its title suggests, it’s a game dedicated to King Arthur, the legendary British leader who was given the famous Excalibur sword which is associated with magical powers and rightful sovereignty of Britain. In addition, the game belongs to the “Book of” group of slots, but instead of having the usual Ancient Egyptian layout, this time we are taken to England.

To win, you need to match at least 2 of the high-value symbols or wilds, or 3 of the low-value symbols on an active payline, from left to right.

Click on the chip icon on the right side of the reels and choose your preferred bet.

Gameplay and Features on Book of King Arthur Slot

Book of King Arthur is a simple and straightforward game when it comes to the gameplay. You’ll quickly get along with it and learn how to set your bets and spin the reels. Microgaming and Just For The Win have equipped the game with a classic bonus feature - Free Spins. But, the Free Spins come with expanding symbols that increase your chances of winning bigger prizes. Let’s see how you can benefit from this feature.

Free Spins Feature

The Book symbol has a double role in the Book of King Arthur slot. It plays as a wild and substitutes for all regular symbols to help you complete a winning line. But, it also can act as a scatter symbol that triggers the Free Spins feature.

When you land 3, 4, or 5 Book symbols on the same spin, you’ll trigger the Free Spins feature. In return, you’ll receive 10 free spins and a multiplier of 2x, 20x or 200x the stake for 3, 4, or 5 scatters respectively. Before the free spins begin, a wheel will spin to reveal an expanding symbol. Every time the chosen expanding symbol lands during the free spins, it will expand to fill the whole reels and help you create a new winning combination. If you land 3 or more Book symbols during the free spins feature, you’ll receive 10 additional free spins.

The maximum win per free spin depends on the expanding symbol. The higher the value of the symbol, the bigger your potential payouts:

  • 10, J, Q - 100x the stake;
  • A, K - 150x the stake;
  • Shield, Grail - 750x the stake;
  • Excalibur - 2,000x the stake;
  • King Arthur - 5,000x the stake.
