This creates a dynamic grid that expands with each win, unlocking more potential pay lines as the round progresses.
Clearing all rocks in the base game awards eight free spins, where two core features drive engagement. Silver Nuggets increase a progressive win multiplier starting at x1, while Gold Nuggets award additional free spins, extending the round and increasing overall win potential.
To improve access to the bonus round, the Bonus Chance feature is available, doubling the probability of triggering free spins in exchange for a higher stake.
Players can also opt for the Bonus Buy feature to enter the free spins mode directly.
