Book of Tombs is an impressive game that draws inspiration from the popular theme of exploration and Ancient Egypt found in online slot games. If you're a fan of Rich Wilde's games, like Rich Wilde and the Book of Dead, you'll notice familiar elements in this one. The background of the reel set is adorned with hieroglyphics and bordered with shades of gold and blue. Two massive pillars with hieroglyphics and images of Ra decorate the backdrop.
In Book of Tombs, you'll come across traditional Egyptian symbols, along with the usual playing card symbols like tens, jacks, queens, kings, and aces. The higher-paying symbols are framed in gold, making them easily distinguishable from the lower-paying symbols. The colour scheme combines gold tones with burnt oranges and occasional bursts of royal blue, creating a sophisticated and opulent atmosphere.
One of the exciting features of Book of Tombs is the unlimited free spins bonus round, where symbols can expand.
To trigger the unlimited free spins feature, you'll need a minimum of three scatter symbols anywhere on the screen. If a sufficient number of these symbols appear, they will expand into other reels, potentially resulting in significant winnings. During the free spins feature, if three or more scatter symbols land anywhere on the screen, an additional eight free spins are triggered, and a new expanding symbol is chosen at random. It is possible to have up to nine different expanding symbols, which could lead to substantial wins.
The scatter wild symbol is the only one that does not expand. After winning in the base game, players have the option to gamble their winnings in order to double or quadruple their return. To double the amount, players must correctly predict the colour of the next card drawn. To quadruple the amount, players must correctly predict the suit of the next card drawn. If the guess is incorrect, all winnings from that spin are lost.
