Bonus Features in Book of Kings

The Book of Kings slot game comes with just the 1 bonus feature – the Free Games feature. You get 10 free spins with scope to win more. You’ll also benefit from a special expanding symbol. However, trigger the feature with the book and snake symbol for a trebling multiplier.

Free Games feature

The Free Games feature is central to the action and is played when you see 3 or more Book or Book and Snake symbols landing simultaneously anywhere on the reels. Your reward is 10 free spins however you activate the feature – the difference is the multiplier in play:

3 or more Book symbols 10 free spins with 1x multiplier
3 or more Book and/or Book and Snake symbols 10 free spins with 3x multiplier

Prior to the free spins beginning, a symbol is randomly chosen to act as the special expanding symbol for the duration of the feature. When it appears, it will expand to take over the whole reel. If you get this symbol on all 5 reels, you will get a screen full of the same symbol. The symbol you want is the female adventurer as she is the most valuable.

Below is a table which highlights the maximum win if you achieve a screen full of the same symbol, with both the 1x and 3x multiplier options:

Symbol(s) Win with 1x Multiplier With 3x Multiplier
Female adventurer 5,000 x stake 15,000 x stake
Tutankhamen 2,000 x stake 6,000 x stake
Horus & Eye of Ra 750 x stake 2,250 x stake
A & K 150 x stake 450 x stake
Q, J & 10 100 x stake 300 x stake

Finally, you can retrigger the feature to give you a further 10 free spins – which takes you total to 20 free spins altogether.
