This game is set across a 5×3 reel layout with 10 paylines, where players can wager from $0.10 to $200 per spin. The objective is to match symbols across paylines to win, with the game boasting an RTP of 96.19% and high volatility.

Bonus Features

The Book of Thieves is laden with enticing bonus features that elevate the gameplay, including:

The game’s symbols draw deeply from its medieval theme, with each symbol adding to the overall narrative:

  • Lower-value symbols include bronze and silver coins, imbuing the game with a sense of treasure and wealth.
  • Higher-value symbols feature a cast of characters including a bearded man and a glamorous woman, who could be the leader of the band of thieves or their unsuspecting victim.
  • The book symbol serves as a scatter, pivotal for triggering free spins and expanding symbols.
  • The wild symbol is represented by a bag of gold, offering players the chance to complete winning paylines with its substituting abilities.

These symbols are meticulously designed, contributing to the game’s immersive medieval atmosphere and storyline.


Book of Thieves offers players a range of payouts depending on the symbols matched. Here’s a brief overview:

Symbol 3 of a Kind 4 of a Kind 5 of a Kind
Bronze Coin, Silver Coin 0.5x 1x 5x
Bearded Man 0.2x 2.5x 10x
Glamorous Woman 1x 10x 100x

This table highlights the potential for lucrative wins, especially when higher value symbols are matched.


The Book of Thieves game features 10 fixed paylines, offering various ways to win. Wins are counted from the leftmost reel to the right, providing a straightforward and accessible understanding of how winning combinations can be achieved.
