Prepare to encounter the formidable but amicable cave troll, Gronk, as he embarks on a gem-collecting journey! Dive into a game featuring a cluster win mechanic, a 6x6 grid with cascading wins, and the potential for a maximum win of 7,500x!

Symbol wins induce a charged state for that specific symbol type, marked by a distinctive glow effect. The charged symbol types are also showcased in the "charge bar" display above the grid. These charged symbols maintain their heightened state until the conclusion of the ongoing round. The Epic Gem symbol may descend during cascades and activates once the grid settles, following the cessation of wins or cascades. Upon activation, all currently charged symbols transform into the highest paying charged symbol. The Epic Gem, accounting for 4 symbols, ensures a minimum win of 5 symbols as long as there is at least one charged symbol on the grid. The absorbed symbols and the Epic Gem are then removed, prompting another cascade. Notably, symbols do not enter a charged state during the Gem Hoarder game mode.

Trigger the Gem Hoarder game mode by landing 3 or more Gronk’s Head scatter symbols simultaneously in the base game, awarding 10 free spins. This feature mirrors the base game mechanics but offers an increased likelihood of landing Epic Gems.

Additionally, landing 3 or more Gem Bag scatter symbols simultaneously in the base game activates another feature, granting 5 free spins. This feature introduces a global multiplier that progressively grows with the number of symbols in each winning cluster. Any winning cluster, including the special X-Gem symbol, is multiplied by the global multiplier. In case more than one X-Gem symbol contributes to the same winning cluster, the global multiplier is applied to the win for each X-Gem. To keep the excitement alive, landing 3 or more Gem Bag symbols during this feature refills the life bar. Get ready for an epic adventure with Gronk and the gems!
