Although the title refers to the theme, we are actually mining for gems inside an ice-chilled cave located in Upgradium. The reels are filled with colourful crystals and carved gemstones that gleam against the dark background. The frozen interior can be seen behind the reels and the soundtrack is consistent with the theme.

The paying wild symbol can be substituted for any other symbols. Any win that is won by the wild symbol will be upgraded to the next level in the pay table. This feature is available in both the base game or Crystallisation respins. This feature is activated when an orange crystal lands on a hot spot at the centre of the reels. This feature allows players to get a free spin, and symbols can be upgraded to the next level.
