BGaming Launches Book of Hidden Tombs Slot

BGaming has released Book of Hidden Tombs, a new Classic online slot that revisits Ancient Egyptian themes while adding a progressive multiplier to its Free Spins mechanics.

The game uses a 5×3 reel layout and features Egyptian deities including Ra, Anubis and Bastet. A male explorer character also appears among the high-value symbols, with the game built around the familiar Book Of format and updated bonus features.

Free Spins Bring Expanding Symbols

Book of Hidden Tombs begins with a standard slot game that can lead into two separate Free Spins features. Three or more Book symbols trigger Free Spins, while the Book also works as a Wild, allowing it to substitute for other symbols in winning combinations.

Before Free Spins begin, the game randomly selects one symbol, excluding the Scatter, to become a Golden Expanding symbol. When two or three Golden symbols land during the feature, they expand across the reel and generate wins across all 10 paylines.

Players can receive another 10 spins by landing at least three Books during the Free Spins round. The game also includes Scatter-Wild symbols and a Chance ×2 option, which increases the bet slightly while doubling the probability of triggering Free Spins. Chance ×2 becomes unavailable when Buy Bonus is active.

Super Free Spins Changes The Multiplier

The second bonus round introduces the game's progressive multiplier. Super Free Spins activates when players land three or more Golden Scatter symbols and follows the basic structure of Free Spins while adding the multiplier mechanic.

The multiplier begins at ×1. A losing spin doubles its value, while a winning spin applies the current multiplier to the payout before resetting it. The multiplier can reach ×512.

Players can also purchase either Free Spins or Super Free Spins directly from the main game. The relevant Buy Bonus prices appear in a pop-up and adjust according to the selected stake, with the purchased feature beginning on the next spin.

Book of Hidden Tombs offers maximum wins of up to ×10,000 the stake. The original launch details also list feature purchases at ×100 and ×200 the stake for Free Spins and Super Free Spins, respectively.

Julia Alekseeva, CPO at BGaming, said, “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.”

The release combines familiar Egyptian imagery with additional ways to enter its bonus rounds, while the progressive multiplier gives the Super Free Spins feature its central gameplay distinction.
