Prism of Gems Bonus Features

Game Symbols

The name of this game hints to players that there will be gems, loads of colourful and expensive gems, on the reels. 

The cards are the lowest symbols players can meet, and there are 2 types of them: 9–J pay 0.1–0.4x, and the higher cards, such as Q–K, pay 0.2–0.6. The value of the A is 0.2–0.7x.

The crystals are also different when it comes to their shapes and colours. A pink gem provides 0.5–1.4x, a green one – up to 1.5x. A square yellow stone provides 0.7–2x, and a round blue gem – up to 3x.

Wild is a glowing diamond, and the stained glass is a Scatter. Bonus symbols can land on any reel.

Bonus Rounds & Free Spins

We’ve already mentioned that there are a bunch of bonus options to brighten up the base game.

  • Multiplier Reel is a horizontal reel above reels 2–4. It consists of 3 spots with symbols that land on them. Each one displays multipliers that start at 1x and are increased by 1 with each cascade of this reel. The maximum multiplier per spot is 7x, and when 3 of them have the maximum value, the total multiplier comes up to 343x. But not all combinations are multiplied by this number: only those that include symbols that are located on the spot above.
  • Cascading reels provide consecutive spins within 1 spin: winning symbols burst and the new ones land in their place.
  • If a symbol matches the Multiplier Reel symbol on the spot, it splits. And if a Wild is above, it splits all symbols below. This way, the number of symbols per reel can come up to 7.
  • Free Spins, as usual, are launched with Scatters: 3, 4, or 5 symbols trigger 10, 15, or 20 FS. If there are multipliers during the base game, they are carried into the bonus game. Plus, they are built progressively until the end of the bonus game. And each Scatter during the feature adds 2+ extra spins.
