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!
The trolls have returned, fiercer than ever! Within the depths of Troll's Temple lies untold riches, but adventurers must first navigate treacherous trials against these monstrous adversaries.

For generations, these creatures have plundered travelers crossing the bridge. Now, it's time to turn the tables and pilfer from the thieves themselves. Traverse the massive bridge, confronting the formidable troll who may manifest at any moment as a colossal symbol!

The mystical cauldron holds the promise of boundless treasures, while the mega bonus stone can amplify any victory! Those daring enough to trigger Free Spins must brace themselves for epic encounters with towering trolls... the clash begins!

During the Base Game, three scatters lower the drawbridge, revealing the entrance to the Free Spins dungeon through the Pick n Click gate. Engaging the Golden Bet feature prior to Free Spins grants an additional selection that could tip the scales in one's favor. Additionally, in the Base Game, the Bonus Cauldron feature can activate randomly, awarding Free Spins or Coins. When a Flaming Boulder strikes the reels, multipliers of x2, x3, x4, or x5 come into play. A colossal troll may emerge, spanning two reels and transforming into a wild symbol. Should the troll gleam with golden light, victory is assured, and rewards will flow abundantly!

Three or more Free Spin symbols trigger the Free Spin mode with Extra Features, maintaining the same bet and lines as the initial activation. Before commencing Free Spins, players select concealed features from a deck of cards that will be activated during the Free Spin session. Free Spin symbols are absent during Free Spins.

Each card can only be drawn once, with only one 2x2 Colossal symbol card available for the entire Free Spin session. Among the 18 selectable cards are various features, such as additional Free Spins, multipliers on all wins, random placement of wilds, and colossal troll symbols in different colors.

Activation of the Golden Bet feature grants players an extra feature pick upon entering Free Spin mode. This enhancement requires an additional 10 coins per spin and can be toggled on or off between spins in the base game.

In both the base game and Free Spins, 2x4 symbols may appear on the reels, functioning as regular symbols with equivalent payouts to their smaller counterparts. Colossal symbols are exclusive to high-paying symbols.
