To form a winning combination in the Book of Thieves online slot, you will need to land 2 or 3 matching symbols on the 10 paylines available, depending on the type of symbol. The lower-value symbols are represented by gold coins, silver coins, copper coins, daggers, and goblets. You will need 3 of these on a payline to generate a win. The higher-value symbols are represented by the main characters (the thieves). You will only need 2 matching thieves on a payline to form a win. You will also find a scatter symbol (the book) and a wild symbol. A great addition to the game is that both the wild and the scatter symbols payout. As for the best-paying symbols of the slot, these are the wild and the female thief.
