BGaming launches Book of Hidden Tombs slot with progressive multiplier

BGaming has released Book of Hidden Tombs, a new addition to its Classic slot range that introduces a progressive multiplier mechanic to the popular ‘Book-of’ format.

In the game’s Super Free Spins round, a multiplier increases on every losing spin, starting at x1 and doubling with each dead spin up to a maximum of x512. This mechanic is designed to reframe non-winning spins as progress toward a larger potential payout. The title features a 97% RTP, high volatility, and a maximum win of x10,000.
