Prism of Gems slot review (Play’n GO)

Prism of Gems has more to offer, though. The gameplay is highly effective, and the graphics are fantastic and not too overwhelming. Yes, the gems might be a little dull, though, but by no means does that impact the quality of the slot.

Prism of Gems – Play’n GO shifts to more volatile slots

The maximum win of this slot is a blistering 30.000x, and it’s possible to land three million.

Play’n GO has just released the other brutal Coils of Cash slot (max win 30.000x) and Hammerfall slot (max win 30.000x).

It looks like Play’n GO seeks ways to attract the high rollers and cut off the likes of Big Time Gaming and Nolimit City. Even though these providers provide slots with a maximum win over 50.000x, it’s clear that Play’n GO is talking some serious business.


Number of paylines: Up to 3087 win ways

RTP and variance: 96.24%, Very High variance

Maximum win: 30,000 x the bet or  $€3.0 million

Betting range: $€0.20 – $€100

Bonus features: Free spins

Casino Hipster verdict: Hot, but not HOT! It’s too difficult to land the free spins (which is fair for such a volatile slot), but the game becomes a bit dull as a result of it.

Gameplay and Features

Prism of Gems has a 5×3 setup, and above the middle three reels, you see a multiplier reel. The multiplier reel has the same symbols as the regular reels.

A symbol of the regular reels splits into two if it has the same symbol as on the multiplier reel.

If you have a wild symbol on the multiplier reel, you see that all three symbols below split into two.  In the best case, you have six symbols on the three middle reels. It leads to 3087 ways to win (3x7x7x7x3) according to the win all ways mechanic.

You also have the cascading feature, where you gain a free re-spin following a win and where winning symbols disappear and make way for new symbols.

The high paying symbols are the four gems (blue, orange, green and purple) and the six lows are the 9, 10, J, Q, K and A.

The Diamond framed in gold is the Wild symbol, and the Scatters are the beautiful Stained Glass Windows.

The Multiplier reel – increasing Multipliers

The multiplier reel has another function, the multipliers. We have seen this feature with Coils of Cash.

The symbols start with an x1 multiplier, but if the corresponding reel cascades (following a win), you’ll see that the multiplier goes up by +1.

In the best case, you have x7 multipliers on all three middle reels. It gets you a total win multiplier of 343x!

The multipliers reset back to x1 once you fail to make a win.

How do you win the free spins?

You win 10, 15 or 20 free spins if you spin 3, 4 or 5 Scatters.

During the free spins, you gain another two free spins for each additional scatter you may spin.

The free spins – watch out for the multipliers on the multiplier reel

The free spins have the same gameplay as the main game, but the key difference is that the multipliers (which carry over from the base game) won’t reset.

Now you need to hope for many winning cascades, which will build up a massive win multiplier.

Prism of Gems slot: the payout rate (RTP) is 96.24%

The RTP of Prism of Gems is 96.24%, around the average of the RTP’s of all Play’n GO slots.

Beware, though, with Play’n GO slots: not all trustworthy online casinos offer this game at this RTP. Some have an RTP, which is 1 or 2 % points lower.

Prism of Gems slot: the variance (volatility) is very high

Prism of Gems is a very volatile slot, if not extremely volatile, given its enormous win potential (max win of 30.000x).

If you think that the famous Book of Dead slot is volatile, you may think otherwise. It has a  max win of “only” 5.000x!

Pros en Cons



  • Fantastic animations and pleasing on the eye
  •  A massive win potential
  •  Captivating gameplay with the split symbols and multipliers


  • It’s a risky game, and not everyone will land the three million!
  • It takes a long time to win the free spins. At times I wonder why Play’n GO is not into having the Buy a Bonus feature.

The wagering requirements on all deposit bonuses are quite decent: 40 x the bonus amount. Don’t forget: If you want to avoid these bonus wagering requirements, you can always choose to decline any bonus. The max bet per spin with bonus money is unusually high at $15 per spin.
