About Gronks Gems

Gronks Gems is a grid-based slot developed by Hacksaw, played on a 6x6 layout. The game features cascading wins, where winning clusters are removed and replaced by new symbols. Players can achieve a maximum win of up to 7,500 times their bet. The main character is Gronk, a cave troll renowned for his love of collecting gems.

Game Features

Charged Symbols & Epic Gem

  • When symbols form a winning cluster, those symbol types become charged and begin to glow. These are displayed in a dedicated charge bar above the grid.
  • Charged symbols hold their status until the end of the current spin.
  • The Epic Gem scatter symbol may appear after cascading wins are completed. It transforms all charged symbols on the grid into the highest paying charged symbol.
  • All charged symbols are absorbed by the Epic Gem and count as a new winning cluster. The Epic Gem counts as four symbols.
  • Once charged symbols are absorbed, the Epic Gem explodes and triggers another cascade, giving the chance for additional wins.
  • Charged symbols do not feature during the Gem Hoarder mode.

Gronk’s Treasure Bonus

  • This feature triggers when three Gronk’s Head scatter symbols land during the base game.
  • Players receive 10 free spins when this bonus round starts.
  • The likelihood of Epic Gem symbols appearing is increased during Gronk's Treasure compared to the base game.

Gem Hoarder Feature

  • To activate Gem Hoarder, land three Gem Bag scatter symbols during the base game.
  • This feature awards 5 refilling free spins.
  • If three Gem Bag symbols land during this bonus, the number of free spins is reset to five.

Progressive Global Multiplier in Gem Hoarder Mode

  • When winning symbols are removed, a global multiplier increases by the number of symbols eliminated.
  • Clusters that are connected to the X-Gem symbol are multiplied by the current global multiplier.
  • If more than one X-Gem symbol is connected to a cluster, the multiplier is applied for each X-Gem involved.

Special Symbols

  • The Epic Gem symbol does not appear during the Gem Hoarder bonus round.
  • The X-Gem symbol works as a wild, substituting for any paying symbol and appears exclusively in Gem Hoarder mode.

The return to player (RTP) is displayed within the game.

How to Win

  • To form a winning combination, connect at least five identical symbols anywhere adjacent on the grid.
  • Winning symbols are removed, and new symbols will cascade into the empty positions. The cascades continue until no further wins occur.
