The Heart of the Action: Bonus Features and Complimentary Spins
This is the point where Book of Dead cements its storied status. The special features are what generate those jaw-dropping wins, and the whole experience revolves around the Book symbol. As a wild, it can stand in for any other symbol to aid in making a winning line. Its actual potential, though, triggers when three or more Books appear anywhere on the screen, initiating the famous Free Spins round. Here’s the clever bit. Before the free spins start, the game randomly picks one standard symbol to become an expanding symbol. During the free spins, if enough of that particular symbol lands to create a win, it expands to fill its whole reel, greatly increasing your payout. I’ve seen this mechanic turn a uneventful round into a phenomenal win more times than I can count. You can also retrigger more free spins by getting additional Book scatters during the bonus round. This mix of a simple trigger and a potentially game-altering expanding symbol creates a flawless cycle of suspense and reward. It’s a slot design stroke of genius where one feature directly fuels the chance for a monster payout.
