Book of Hidden Tombs runs on a classic 5×3, 10-payline setup with high volatility, a published 97.00% RTP and a x10000 maximum win. The Book symbol doubles as Wild and Scatter, with 3 or more Books triggering the regular Free Spins round. Before those 10 Free Spins begin, a regular symbol is randomly chosen as the Golden Expanding Symbol; landing enough copies allows it to expand across reels and generate wins across the paylines. Three or more Books during the feature can retrigger another 10 spins, giving the traditional Book mechanic plenty of room to develop.
Super Free Spins add the game’s most aggressive mechanic. This mode uses a progressive multiplier beginning at x1: every non-winning spin doubles it, while the next win applies the accumulated multiplier and then resets it. That multiplier can climb as high as x512, creating an unusual risk-reward loop where dead spins can actually build anticipation rather than simply drain the bonus. BGaming also includes Bonus Buy access, Rebuy functionality and Chance x2, which increases the cost of the spin slightly while doubling the probability of naturally triggering Free Spins.
Crypto slot grinders should appreciate the unusually strong 97.00% theoretical RTP combined with a high-volatility x10000 ceiling. The stated Free Spins frequency of roughly 1 in 195 spins gives players a useful benchmark for longer sessions, while Bonus Buy and Chance x2 offer alternative ways to concentrate play around the feature-heavy part of the math model. It is particularly well suited to players who enjoy volatile Book slots but want more dynamic bonus progression than the standard expanding-symbol formula.
