A Horde of Extra Features

Winning symbols disappear and those above them drop down. This cascade feature of the Gronk’s Gems slot machine repeats as long as you see winning clusters. All instances of winning symbols on a spin or series of cascades are ‘loaded’. They accumulate in a meter above, and once no more winning clusters are seen, a multicolored Epic Gem can convert all charged symbols into the highest value examples.

The Epic Gem then absorbs the number of Charged symbols, pays out a prize and explodes to trigger another cascade. Play Gronk’s Gems for free on this page to see how this exciting slot machine bonus feature works in practice.

Gronk’s disembodied head in three locations triggers ten Free Spins, during which Epic Gems can appear more often. Jewel bags in three locations award the Gem Hoarder feature. Five ‘refill’ free spins are played, with each new bag resetting the spin counter to five.

A multiplier increases throughout and is equal to the number of winning symbols removed in each spin or cascade. Look out for the special X-Gem symbols as they multiply the value of adjacent clusters by the global multiplier amount.
