Gronk’s Gems drops a friendly cave troll into a glowing gem cave, but the real charm is in how the symbols react after a win. Instead of paylines, wins form through clusters of 5 or more matching symbols on a 6x6 grid. Winning symbols disappear, new gems fall in, and the round can keep moving through cascades. Each winning symbol type also becomes charged for the current round, marked with a glow and tracked above the grid, which gives every cascade a little extra purpose.
The Epic Gem can land during cascades and activates once the grid settles. When it does, all charged symbols convert into the highest paying charged symbol, then get absorbed and counted as one cluster before another cascade begins. Gronk’s Treasure triggers from 3 or more Gronk Head Scatters and awards 10 Free Spins with a higher chance of Epic Gems. Gem Hoarder starts from 3 or more Gem Bag Scatters and awards 5 Free Spins, using a global Multiplier that grows with winning clusters. The X-Gem Wild appears only in Gem Hoarder and can multiply cluster wins by that global Multiplier.
• Charged Symbols: Winning symbol types become charged and stay active until the round ends, giving later cascades more impact.
• Epic Gem: After cascades stop, the Epic Gem converts charged symbols into the highest-paying charged type and absorbs them as one cluster.
• Gronk’s Treasure: 3 or more Gronk Head Scatters trigger 10 Free Spins with better Epic Gem potential.
• Gem Hoarder: 3 or more Gem Bag Scatters trigger 5 Free Spins with a growing global Multiplier and X-Gem Wild action.
