You can enter Gronk’s cave dwelling from 0.10 to 100 credits per spin. This game has a high volatility rating and a 96.24% RTP. Optional RTP designs of 94.42%, 92.20%, and 88.30% will be chosen by some online casinos. Open the game info upon loading to check the version in play.
Gronk is a cave troll with a penchant for sparkly gems. He carries his sack of gems next to the game window set against the entrance to his cave. Nighttime blue skies cast a magical glow over the landscape, which matches the blue aura of symbols charged by game features.
The pay symbols start at the low end with coloured gemstones in green, blue, purple and yellow, awarding from 0.2x – 200x your bet for 5 to 36 matching symbols. Larger gems follow in blue, purple, yellow, and red, and clusters of 5 to 36 matching symbols will pay from 0.5x to 1500x stake.
A multi-coloured diamond represents the Epic Gem Scatter, which works with the Charge Bar above the reels for a symbol collect feature. Gronk’s Head represents a scatter symbol that triggers Gronk’s Treasure for landing three or more on a spin, and landing three Gem Bag scatters awards the Gem Hoarder bonus game.
Gronk’s Gems Slot Features
Gronk’s Gems is the latest game to join the Pocketz Series, a specially designed range for mobile, for simple and engaging gameplay on the go. OmNom is the studio’s debut title from the Pocketz Series and the game that launched Hacksaw’s expansion from scratchcards to online slots. Cubes 2, The Bomb, and The Respinners are earlier titles that helped cement the range and lead us to a closer look at Gronk’s Gems.
On every spin, 36 symbols drop onto the 6×6 grid. Groups of five or more horizontally or vertically adjacent symbols form a cluster. Winning clusters are removed from the reels, creating space for new and existing symbols to cascade and fill the gaps. Cascading symbols can lead to more cluster wins, in which case the process repeats until no more wins occur. At the end of a spin sequence, the sum of all cluster wins is paid.
Each of the eight pay symbols is represented in a meter above the play area named the Charge Bar. When a cluster win explodes, the corresponding symbol in the Charge Bar is lit, and all examples of the same symbol left in view become highlighted as Charged versions until the end of the spin.
When an Epic Gem Scatter lands, all Charged symbols transform into the highest-paying Charged symbol on display before being absorbed and added to the Epic Gem for a cluster win. The Epic Gem always starts with a count of four symbols, ensuring a cluster win regardless of the number of Charged symbols being absorbed. When finished, the Epic Gem explodes from the grid, triggering a cascade.
Land three Gronk’s Head scatters to trigger the Gronk’s Treasure bonus game. The round starts with ten free spins, which cannot be retriggered. The bonus comes with a greater chance of landing the Epic Gem symbol on a free spin for bigger win potential.
Three Gem Bag scatters in view award the Gem Hoarder bonus game. This bonus begins with five free spins that can be refilled by landing a further three Gem Bags on a spin. This bonus features a progressive win multiplier, which is increased throughout the bonus by the number of symbols contained within each cluster win. For example, two cluster wins on the first spin containing five and six symbols would increase the win multiplier from x1 to x12.
The multiplier does not reset between spins and is applied to all cluster wins that contain the X-Gem symbol. The X-Gem is a special symbol that features in the Gem Hoarder bonus game only and acts as a wild. This bonus game does not feature the Epic Gem symbol and ends when spins expire.
Where available, you can skip the base game and head directly to one of the bonus games by using the Bonus Buy Feature. Gronk’s Gems comes with three options for a fixed amount:
- Bonus Hunt Featurespins | 3x Bet: With this mode enabled, you are five times more likely to trigger one of the two bonus games.
- Gronk’s Treasure | 110x Bet: Direct entry to the Gronk’s Treasure bonus game.
- Gem Hoarder | 200x Bet: Direct access to the Gem Hoarder bonus.
Gronk’s Gems is another devilishly simple addition to the Pocketz Series with Hacksaw’s trademark multiplying mechanics. The base game features a symbol transformation and collect feature charged by cluster wins and activated by the Epic Gem for decent win potential from a lengthy spin sequence. And the free spins bonus amps up the excitement with a higher chance of landing Epic Gems.
But for many Hacskaw Gaming fans, the real treat can be found in the Gem Horder bonus game, which takes inspiration from the studio’s innovative Stack ‘Em release for dizzying multipliers capable of catapulting regular wins into monstrous ones. Gaming with Gronk is an enjoyable experience for fans of Hacksaw volatility and thrilling bonus games. The only negative is the 7,500x bet max win potential, which is on the low side compared to others in the range.
