BGaming Launches 'Book of Hidden Tombs' Slot Adventure

BGaming has rolled out an exciting new addition to their online slot collection with the release of Book of Hidden Tombs. This game dives into the mystical world of Ancient Egypt, embellishing the classic theme with captivating mechanics, specifically a progressive multiplier linked to its Free Spins feature.

The game’s design showcases a traditional 5×3 reel layout with symbols that capture the essence of Egyptian mythology, such as Ra, Anubis, and Bastet, alongside a daring male explorer character. Central to its gameplay is a familiar "Book Of" format, updated with intriguing bonus features to heighten excitement and engagement.

Unleashing Free Spins with Expanding Symbols

At the core of 'Book of Hidden Tombs' is its Free Spins features, ensuring players have the potential for rewarding outcomes. Free Spins are triggered by the presence of three or more Book symbols on the reels. These symbols not only open the gateway to Free Spins but also act as Wilds, substituting for other symbols to create winning combinations.

Before the Free Spins commence, the game randomly selects one symbol, other than the Scatter, to transform into a Golden Expanding symbol. These Golden symbols, if they appear in groups of two or three during the Free Spins, will automatically expand across the reels, providing the opportunity to reap rewards across all 10 paylines. Moreover, players can secure an additional set of 10 spins by landing three or more Book symbols again during the Free Spins round.

Other enticing features include Scatter-Wild symbols and a Chance ×2 option, which slightly increases the stake while significantly boosting the probability of triggering Free Spins. However, it's important to note that the Chance ×2 option is unavailable when the Buy Bonus feature is in use.

Super Free Spins and the Thrill of Multipliers

What sets Book of Hidden Tombs apart is its unique Super Free Spins bonus round, which introduces a progressive multiplier into the mix. This feature is activated when players land three or more Golden Scatter symbols. The Super Free Spins rounds operate similarly to regular Free Spins, but with the added twist of a multiplier mechanic.

This multiplier begins at ×1, doubling with each losing spin, while a winning spin applies the multiplier value to the payout before resetting it back to its base. Remarkably, this multiplier can climb up to ×512, significantly enhancing the potential for substantial wins.

Players have the power to directly engage with both Free Spins and Super Free Spins through the Buy Bonus option from the main game interface, with costs dynamically adjusting based on the selected stake. The possible winnings can reach up to ×10,000 the player's initial stake, creating a highly lucrative gaming scenario.

Alongside these mechanics, Julia Alekseeva, CPO at BGaming, elaborates, “With Book of Hidden Tombs, we are combining two iconic elements of online slot gaming: Ancient Egypt and the hugely popular ‘Book-of’ gameplay mechanic. With Book of Hidden Tombs, we have upped the excitement found in traditional ‘Book-of’ titles with the addition of the Super Free Spins bonus. The progressive multiplier adds a new element to the action. Not only does it create the chance for bigger wins, but it also helps remove the frustration of continued losses, which is a huge benefit for both players and operators.”

This release brilliantly blends the well-loved Egyptian theme with immersive gameplay enhancements, crowned by the innovative progressive multiplier that defines the Super Free Spins feature.
