Prism of Gems Game Overview

Prism of Gems is a gemstone-themed slot from popular online slots developer Play’n GO. The gameplay is set against a well-lit glass dome with classic stone designs, like an ancient museum. 

It is a high volatility slot with an RTP of 96.24%. Its bet sizes range from £0.20 to £8 per spin. Prism of Gems slot offers up to 3,087 winning ways. It also has incredible bonus features, such as a multiplier reel, splitting symbols, and cascading reels.

This 5-reel slot features a gentle soundtrack, which gives it a sophisticated touch. Prism of Gems has symbols consisting of tiles of radiant and glittering marble. The symbols are split into high-paying gems and low-paying card values A – 9.

The game’s wild is represented by the gemstone with rainbow colours. The wild can replace all other symbols except the scatters. Furthermore, the wild only appears on the multiplier reel. On the other hand, the scatter is represented by a round symbol resembling a stained glass window.

The reels appear in a 3-4-4-4-3 format. However, the reels can further expand to a 3-7-7-7-3 format via a splitting symbol mechanic.

How to Play Prism of Gems

  • Log in to your account at King casino.
  • Select Prism of Gems and load the game.
  • Choose your bet amount with the minus “-” or plus “+” sign beneath the reels.
  • Click the blue information (i) symbol to view the paytable.
  • Then, if ready, click the curved arrows in the green circle to start spinning the reels.

Cascading Reels

The cascading reels feature triggers following a win. During this feature, the winning symbols are removed from the reels to allow new symbols to land in the empty spaces, potentially allowing for another winning combination. 

This feature repeats until the winning streak ends.

Multiplier Reel

Sitting atop the reels is a 3-row horizontal reel called the multiplier reel. Every symbol that appears on the horizontal reel has an x1 multiplier affixed to it.vThe multipliers apply to wins of the same symbol on the reels below.

 If you land a cascading avalanche in the reel below the horizontal reel, the multiplier above increases by +1, up to a maximum of x7. 

Hence, the multiplier reel feature can reward you with up to x343 multiplier if the symbols on the horizontal reel are maxed out.

Extra Spins Feature

Landing at least 3 scatters in the same spin triggers the Extra Spins round. The number of scatters determines the number of Extra Spins you receive. 

  • 5 scatter symbols = 20 Extra Spins
  • 4 scatter symbols = 15 Extra Spins
  • 3 scatter symbols = 10 Extra Spins

If you land an extra scatter on the reels, you may get 2 more Extra Spins. 

During this feature, any multipliers from the base game carry over.

Return To Player

Return to Player (RTP): 96.24%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
