This high RTP (96.24%), medium volatility fantasy-themed slot takes players on a magical adventure with some enticing bonus features.
Read full reviewGronk's Gems has a fantasy theme, focusing on a mysterious troll and his treasure.
In a dark forest, players will be seized by fear as they encounter a large magical being: Gronk. They’ll soon discover that this kindly troll means them no harm, and may have a few gems to share.
Those who enjoy fairytales will particularly appreciate this adventure with Gronk.
Gronk looms beside the reels, his body adorned with jewels. Although he appears intimidating with his muscular body and sharp teeth, Gronk’s gentle expression suggests he has no intention of attacking. Instead, this troll seems curious to meet the players.
The setting is a moss-covered forest lit by the moon. The foliage of the backdrop blends together as if painted in watercolor. This helps create an enchanting atmosphere.
The symbols include a tantalizing array of precious gems, some cut to perfection and others partially encased in rock. Violet amethyst, yellow citrine, and red rubies can all be found in the hoard.
The playful background music has a classical feel, while owl hoots help to establish the night time scene. A gentle oinking sound can also be heard, presumably made by Gronk himself.
Together, the animation and soundtrack give a magical twist to a classic gem theme.
Gronk’s Gems is a six-reel, six-row slot. Wins are awarded for landing 5 or more connected matching symbols anywhere on the reels.
Players may choose to buy into the Bonus if they choose (further details below). When players buy directly into the Bonus, the RTP will increase slightly, depending on the Bonus purchased.
When symbols are part of a winning combination, they vanish, making way for new symbols to fall into their place. These Cascades continue until there are no more winning combinations possible.
The maximum win for this slot is 7,500x the player’s total bet.
When a symbol type is part of a winning combination, other symbols of that type will begin to glow, indicating they are entering a charged state. A charge bar above the reels shows the status of different symbol types.
The Epic Gem Scatter symbol can appear after a Cascade sequence, prompting every charged symbol to transform into the highest paying charged symbol. These symbols are then counted as a single winning cluster, with the Epic Gem symbol counting as 4 symbols. Another Cascade is then triggered.
If players land at least 3 Gronk’s Head Scatter symbols, the Gronk’s Treasure Bonus is triggered. This feature starts with 10 free spins and features a higher chance of Epic Gem symbols appearing.
The Gem Hoarder Bonus is triggered when players land 3 Gem Bag Scatter symbols. This feature offers 5 free spins, with the free spin count resetting to 5 when players land 3 Gem Bag Scatter symbols during the feature.
The Gem Hoarder Bonus offers a progressive multiplier that increases whenever winning symbols are removed. If any winning combination is connected to the X-Gem symbol, that win is multiplied by the global multiplier.
The return to player of Gronk's Gems is 96.24%, slightly above our yardstick for average of roughly 96%.
The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.10 up to a maximum of $/£/€100 per spin.
Gronk’s Gems offers medium volatility, making this slot a less ideal match for our preferred slot machine strategies. Our slot strategies target the highest possible volatility.
We recommend this high RTP, medium volatility fantasy-themed slot.
With an endearing main character, beautiful animation, and a solid RTP, Gronk’s Gems has immediate appeal. However, the moderate volatility will leave mathematically-inclined players less entranced.
The creative range of bonus features adds additional fun to this magical slot.
