About Gronk's Gems Slot

Troll-themed, the Gronk's Gems slot by Hacksaw Gaming comes with a 6x6 game grid using a Cluster Pays mechanic. Players form winning combos when five or more matching symbols land adjacent in a cluster. The more matching symbols in a group, the higher the payout.

Betting starts at just £0.10 per spin, going up to £100. You can adjust your preferred betting amount in the Bet section, with payouts changing accordingly. Finally, the Gronk's Gems slot has a maximum potential win of up to 7,500x your total wager.

Design, Symbols, and Graphics

The Gronk's Gems slot is an excellent Hacksaw Gaming slot with beautiful animations and crisp graphics. It gave me a dark, mysterious feel, and the friendly troll was not scary. At least not for me. I found it very likeable.

The setting of the slot is in a forest, with blue being the dominant colour. Gronk, the troll, is left from the grid. Symbols are lit, including green, blue, yellow, and pink gems, a blue octagon, a purple hexagon, a gold star, and an orange diamond gem. The orange diamond gem pays the most, with 36+ symbols in a cluster paying out 1,500x your bet.

Interestingly, the Gronk's Gems slot does not have a Wild Symbol. However, there is an Epic Gem Scatter (which appears in the Charged Symbols Feature), a Gem Bag Scatter (three of them trigger Gronk's Treasure Feature), and Gronk's Head Scatter (three of them trigger Gem Hoarder Feature).

There is also an X-Gem, which only appears during the Gem Hoarder Feature.

RTP, Variance, and Payouts for Gronk's Gems Slot

Gameplay and Features on Gronk's Gems Slot

The Gronk's Gems slot contains five bonus features. Here is the breakdown of each of them.

Cascade Win Feature

When you form a winning combo, the Cascade Feature enters into play. The winning symbols will explode, and new symbols will take place in the empty spaces. That can give you another chance to win, and the cascade continues as long as there are winning clusters on the grid.

Charged Symbols Feature

When landing a winning cluster, the winning symbol gets charged and glows. These symbols will appear above the grid in the "Charge Bar." They will remain charged until the end of the spin. When there are no more wins, the Epic Gem Scatter will transform the charged symbols into the highest-value charged symbol.

Gronk's Treasure Feature

You will activate this feature if three Gem Bag Scatter symbols land in the base game. Then you will receive ten free spins, with increased chances of landing Epic Gem Scatter symbols during the feature.

Gem Hoarder Feature

Landing three Gronk's Head Scatter symbols will trigger the Gem Hoarder Feature. You will then get rewarded with five re-filling free spins. The progressive multiplier will increase when winning symbols get removed from the grid.

Buy Bonus Feature

This feature is only available outside the UK. Players can buy their way into bonus features for specific amounts.

Our Verdict

Hacksaw Gaming's grid slots are always interesting to play. They offer a different type of gameplay from regular slots and can be a lovely refreshment from standard games.

I liked the visuals and exciting gameplay of the Gronk's Gems slot, and the bonus features also kept me entertained. The Gem Hoarder Feature was particularly interesting to me, and it might become your favourite too.

Cluster wins can potentially award as much as 7,500x the stake, which is lower than other grid slots. But the excitement of this game is still the same. Moreover, it offers an above-average RTP and medium volatility.
