GAME FEATURES
Charged Symbols & Epic Gem
Symbol wins make that symbol type enter a charged state and begin to glow. Charged symbol types are also shown in the “charge bar display” above the grid. Symbols retain their charged state until the end of the current spin.
The Epic Gem scatter symbol may drop in on cascades after winning symbols are removed and will activate after the grid has settled, when no more wins or cascades occur. When the Epic Gem activates, all charged symbols on the grid are transformed into the highest paying charged symbol!
All charged symbols are then absorbed by the Epic Gem and counted as if they were one winning cluster. The Epic Gem itself counts as 4 symbols, so that it will always be able to create a minimum win of 5 symbols so long as there is at least one charged symbol on the grid. Once all charged symbols are absorbed, the Epic Gem explodes and triggers another cascade!
Symbols do not have a charged state during the Gem Hoarder game mode.
BONUSHUNT FEATURESPINS
Each spin is 5x times more likely to trigger one of the bonus games!
Gronk’s Treasure
Land 3 Gronk’s Head scatter symbols at the same time in the base game to trigger this bonus game, which awards 10 free spins! This feature has a higher chance to land Epic Gem symbols than the base game!
Gem Hoarder
Land 3 Gem Bag scatter symbols at the same time in the base game to trigger this bonus game, which has 5 refilling free spins. Landing 3 Gem Bag symbols at the same time during the feature refills all 5 free spins!
This feature has a progressive global multiplier that increases whenever winning symbols are removed! The multiplier value is increased by an amount equal to the number of removed symbols. Any winning cluster that connects to the special X-Gem symbol is multiplied by the global multiplier! If more than one X-Gem symbol connect to the same winning cluster, the global multiplier will be applied once for each connecting X-Gem symbol!
SPECIAL SYMBOLS
The Epic Gem does not appear in the Gem Hoarder game mode.
The X-Gem symbol counts as a wild symbol, substituting all other paying symbols, and appears only in the Gem Hoarder game mode.
