Book of Captain Silver Online Slot by Microgaming and All41 Studios is a swashbuckling pirate adventure slot that sees you take to the high seas in search of treasure. This is a thematic departure from other slots that bear the ‘Book of’ name, with a cheerful buccaneer captain featuring as the highest paying symbol alongside other images of pirate gear. The slot’s bonus features include free spins and multipliers.

Game Symbols

  • 10 to A card royals are the low-paying symbols.
  • A compass, a flintlock pistol, a pirate ship, and Captain Silver himself are the high-paying symbols.
  • A magical book acts as both the scatter and wild symbol, triggering free spins and substituting for any other symbol.

Bonus Features


Whenever a book symbol appears, it will be collected in a treasure-filled chest below the reels. Whenever this happens, there is a chance that a bonus wheel will activate, and you will claim one of four fixed jackpots. You could win 15x, 50x, 500x, and 10,000x your bet for the Mini, Minor, Major, and Mega jackpots, respectively.

Free Spins

If 3 or more book symbols appear on the reels, you will be allocated 10 free spins and the book will fly open, revealing a randomly chosen symbol. If enough instances of this symbol land on a spin, they will expand to fill their reels.

Our Verdict

Book of Captain Silver slot brings you a fun side of pirating with some familiar mechanics. ‘Book of’ slots are a regular feature in online casino rosters, but a pirate-themed one is a rarity. The visuals are bold and well-detailed with fun animations to hold your attention. The dual-purpose book symbol does its usual great work, serving as the anchor for all the bonus features, the most exciting of which is the fixed jackpots that could net you the game’s maximum potential of $250 000. This slot offers a fresh take on an established concept and does so with impressive flair.
