Book of the Golden Lion Slot by Zillion Games

The golden book pulls double duty as Wild and Scatter. Land three anywhere and it opens to reveal a random expanding symbol for the entire Free Spins round. On each free spin, wherever the chosen symbol appears, it fills the complete reel. Stacking multiple expanded reels in a single spin is how the bigger payouts build.

A silver book with blue lightning serves as the Mystery Symbol. When silver books land without forming a payline, they all transform simultaneously into the same random symbol - potentially any regular or high-value icon. This second-chance mechanic only fires on dead spins, converting losses into possible wins.

Hold and Ring activates with 6 bonus coins that lock into position and display credit values. Empty cells respin until no new coins land or the entire 15-position grid is full. Jackpot coins for Grand (1000x), Major (100x), Minor (30x), and Mini (24x) can appear during respins. A passive accumulation system tracks progress toward a guaranteed Hold and Ring trigger throughout the session, so the bonus eventually fires even without a natural 6-coin landing.
