Get to Know Gronk

The Gronk’s Gems online slot comes from Hacksaw Gaming and is part of their mobile-first range. 

Gronk is a cartoon creature who looks like the lovechild of a cave troll from Lord of the Rings and Yoda. This animated creature stands hunched to the side of the 6x6 symbol grid, where you see a colorful variety of different gems and bonus symbols.

A Horde of Extra Features

Winning symbols vanish and those above drop down. This Cascades feature of the Gronk’s Gems slot machine repeats for as long as you see winning clusters. All examples of winning symbols on a spin or series of cascades become ‘Charged.’ They collect in a meter above and once no more winning clusters are seen, a multicolor Epic Gem can transform all charged symbols into examples of the highest value. 

The Epic Gem then absorbs the number of charged symbols and pays out a win and explodes to trigger a further 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 places leads to ten free spins, during which Epic Gems can appear more often. Bags of jewels in three places award the Gem Hoarder feature. Five ‘refilling’ free games play out, where any new bags reset the spin counter back to five. 

A multiplier increases throughout and it’s equal to the number of winning symbols removed in any spin or cascades. Look out for special X-Gem symbols, as these multiply the value of adjacent clusters by the global multiplier amount.
