Wilds

As is common on many slots, the Wild symbol replaces other symbols to complete winning combinations in Gemstone Jackpot. However, these wild gems have an added twist – they multiply all winnings by three times their value.

In addition, there are two types of Special Gems that appear occasionally during gameplay:

  • Multiplier Diamonds: These award a 5x multiplier for all wins featuring at least one other diamond.
  • Diamond Combinations Bonus symbol (DCB): Wins with this gem activate the bonus feature, as will be explained in more detail later.

Scatters

The Scatter symbol is represented by the stylized ‘Diamond’ logo. Scattered Diamonds trigger the free spins round when landing three or more anywhere on the reels. In addition to awarding a generous number of complimentary rounds (typically 10-20), scatters can also trigger bonus features like multipliers, wilds, and extended reel sets.

Bonus Features

Several unique features enhance gameplay in Gemstone Jackpot:

  • Free Spins : When three or more scatter diamonds appear on the reels, players are awarded an impressive number of free spins.
  • Multi-Reel Expansions : Activated when scatters land during a spin (3+), these expand each reel from 1 to up-to-4 rows while maintaining the standard game volatility – great opportunities await here!
