Bonus Features

Great Gems is packed with unique features that elevate the gaming experience. Here are some of the notable bonus features:

  • Senior Reels: This innovative feature removes one to seven low-value symbols from the reels for the current spin. When coupled with the Extender Gem feature, it significantly increases the chances of securing a win with a premium symbol.

These features are designed to work in tandem, providing a dynamic and potentially lucrative gaming experience.


The symbols in Great Gems are as varied as they are vibrant, each offering different values:

  • Low-value symbols include simple blue, green, and yellow gems.
  • Mid-range symbols are represented by red, orange, and blue gems, which are held by silver clips.
  • High-value symbols feature fully framed silver and gold gems in an array of colors such as blue, green, orange, purple, and red.
  • The highest value symbol is a shiny diamond that serves as the game’s wild, substituting for all symbols to aid in forming winning combinations.

These symbols are integral to the game’s theme and are key to unlocking Great Gems’ treasures.


Payouts in Great Gems are determined by the combination of symbols landed on the reels. Here’s a simplified table showcasing potential payouts for combinations of five symbols:
