A Wealth of Additional Features

When winning symbols disappear, those above them drop down. This feature, known as Cascades in the Gronk’s Gems slot, continues for as long as winning clusters are present. Winning symbols in a spin or series of cascades become ‘Charged,’ accumulating in a meter above. Once no more winning clusters emerge, a multicolored Epic Gem can transform all charged symbols into high-value examples.

The Epic Gem absorbs the number of charged symbols, awards a win, and triggers another cascade. Play Gronk’s Gems for free on this site to observe how this thrilling slot machine bonus feature works in action.

Three appearances of Gronk’s head offer ten free spins, during which Epic Gems can appear more frequently. Finding bags of jewels in three locations triggers the Gem Hoarder feature, where five ‘refilling’ free games are played, resetting the spin count to five with each new bag.

A multiplier that grows with each winning symbol removed in a spin or cascade is applied. Keep an eye out for special X-Gem symbols, as they increase the value of adjacent clusters by the current multiplier.
