Rules and Gameplay

Gronk’s Gems offers a unique and immersive gameplay experience set in a mystical world filled with treasures. The game unfolds on a 6×6 grid, utilizing a Cluster Pays mechanic instead of traditional paylines. Players form winning combinations by creating clusters of five or more matching symbols, either horizontally or vertically. The game includes cascading reels, where winning symbols disappear to allow new symbols to fall into place, potentially creating consecutive wins from a single spin. The betting range is accommodating, starting from $0.10 up to $100 per spin, making it suitable for both casual players and high rollers.

Bonus Features

Gronk’s Gems is rich in bonus features that enhance the gaming experience and boost winning potential:

  • Avalanche Feature: Winning symbols are removed, and new symbols cascade down to fill the empty spaces, offering additional chances to win.
  • Charged Symbols & Epic Gem: Winning clusters turn symbols into charged states. Epic Gems can appear and transform all charged symbols into the highest-paying charged symbol, creating lucrative winning opportunities.
  • Gronk’s Treasure: Triggered by landing three of Gronk’s Head scatters, awarding 10 free spins with a higher chance of Epic Gem symbols appearing.
  • Gem Hoarder: Activated by landing three Gem Bag scatters, starting with 5 free spins and a global multiplier that increases with each symbol removed. Special X-Gem symbols can multiply winnings further.
  • Buy Bonus: Where available, players can directly purchase entry into the bonus rounds, increasing the volatility but also the potential for high rewards.


The symbols in Gronk’s Gems are beautifully designed, adding to the game’s enchanting atmosphere:

  • Low-Pay Symbols: Four uncut gems in green, blue, purple, and yellow, representing the lower end of the paytable.
  • High-Pay Symbols: More valuable symbols include a blue octagonal gem, a purple hexagonal gem, a star, and a diamond, offering higher payouts for clusters.
  • Special Symbols: Epic Gem, Gem Bag, and Gronk’s Head scatters activate various game features and bonuses.


Gronk’s Gems deviates from traditional paylines and employs a Cluster Pays mechanic. Wins are achieved by forming clusters of five or more matching symbols, connected either horizontally or vertically. This innovative approach to winning combinations allows for more dynamic gameplay and offers players numerous ways to hit winning clusters on the 6×6 grid.
