Book of Hidden Tombs by BGaming at 1xBet

Book Scatter-Wild and Free Spins trigger

The Book acts as both Scatter and Wild: it substitutes for any symbol in winning combinations and triggers Free Spins when 3 or more appear. Landing 3 or more Book Scatters unlocks 10 Free Spins.

Golden Expanding symbol

Before the round starts, one random symbol except the Scatter is chosen as a Golden Expanding symbol. When 2 or 3 Golden symbols appear during Free Spins, they expand to cover the reel and create wins on all 10 paylines regardless of position. Landing 3+ Books during the round retriggers the feature with 10 additional spins.

Super Free Spins progressive multiplier

Super Free Spins is triggered by 3+ Golden Scatter symbols. It works like standard Free Spins but includes an added progressive multiplier. That multiplier starts at x1; if a spin ends without a win it doubles; if a win occurs, the current multiplier is applied and the multiplier value resets. The maximum multiplier value is ×512.

Chance ×2

Players can activate Chance ×2, slightly increasing the bet, to double the probability of triggering Free Spins. The feature is disabled when Buy Bonus is active.

Buy Bonus

Players can trigger Free Spins or Super Free Spins directly from the main game screen by purchasing them at the prices displayed in the pop-up. Buy Bonus values automatically adjust to the selected bet. The next spin after the purchase activates the chosen Bonus game.
