Prism of Gems review

Prism of Gems is a new, intricately designed creation by Play’n GO with 3087 ways to win and an interesting splitting PayWay mechanic, which, together with its cascading wins, works in a similar manner to the Megaways game engine.

Due for release on May 27th, 2021, Prism of Gems has caught our attention due to its balanced mix of rewarding features and high win potential. My Prism of Gems Review below will go into some detail on how the game works and recommend some of the best casinos where you can play it from the UK.

How I tested Prism of Gems Slot

Whenever I review a new slot, I start by playing a good number of rounds in demo mode right away. I also consult the provider’s game info sheet if available to make sure that the information I provide is correct. Here are a few more steps I go through to ensure I impart all the details:

  1. I check how the mechanic works – in Prism of Gems, for instance, I made sure I understood how to unlock the multiplier wins. This gives me a good idea of how likely it is to win big.
  2. I give the slot a good number of spins to determine the hit frequency and the size of payouts – I know that players are often looking for frequent, decent-sized wins throughout, so I assess whether the slot pays out frequently enough also during the base game. I also have a look at the paytable to check the size of payouts.
  3. I check the RTP and volatility – the default RTP is always communicated by the provider, and provides a good idea of how much a slot game pays back to players in the long run. If the developer doesn’t provide any information regarding volatility, I determine this myself based on how easy or difficult it is to land big wins, and on how frequent the payouts are.
  4. I assess the design and sound effects – I know that players these days have come to expect a great audiovisual experience, and therefore I do give attention to how original and immersive a slot game is.

Play Prism of Gems Slot with the best bonus

You can find Play’n GO slots at practically any online casino these days. That said, it’s wise to choose a casino that awards you with a good bonus, especially if you’re trying out a highly volatile slot for the first time!

The below are some of the operators that I recommend for British players who wish to give Prism of Gems a go:

  • Novibet Casino will give new players up to £150 in bonus funds and also runs promotions involving free spins for existing players. Terms apply.
  • Last but not least, our highly recommended Skol Casino will welcome British players with up to £1,300 in bonuses on their first 5 deposits, and its bonus comes with a very decent wagering requirement of just 35x the bonus only.

Skol Casino offers one of the best bonuses at present

Skol Casino will welcome new players with one of the biggest bonuses around, coupled with a very reasonable wagering requirement which is below the average 40x. The casino hosts various Play’n GO games, and you can expect to find Prism of Gems added to its collection at the end of May 2021!

Prism of Gems Symbols and Payouts

Prism of Gems features a number of gem symbols and the usual playing-card numbers and suits. The symbols drop vertically with each spin on each of its 5 reels, whereas a top horizontal reel will always feature 3 additional symbols that slide in from the right. These 3 symbols can also form winning combinations with those on the main reel set.

The Symbols

6 low-value symbols and 5 gem symbols can land on the reels, together with a scatter symbol which is in the form of a stained glass circle. The Wild takes the form of one of the 5 gems, and can substitute any of the symbols bar the scatter.


Wins in Prism of Gems Slot are formed by lending 3 to 5 same symbols on adjacent reels. The payways change with each spin, depending on the number of symbols that split up on each reel, and may total a maximum of 3,087 ways.

The paytable below shows the payouts in store on a bet of £1. As you can see, you will almost never win anything over your stake amount if you land 3 symbol combinations, except in the case of the highest paying symbol, which is the sapphire gem.

However, as we’ll explain down below, the multipliers will occasionally increase the size of payouts and make the game more worthwhile.

High Symbol Paytable

Prism of Gems min/max bet

The betting options in Prism of Gems slot range between 20p and £100. There’s an autoplay button allowing you to set between 10 and 100 spins on autoplay, with 3 different stop limits

Prism of Gems RTP

The default RTP in Prism of Gems is set to 96.24%, which is slightly above average.

Volatility and hit frequency

The volatility in this game is high, and you usually need to factor in a good number of spins in order to reap the bigger rewards. Although the hit frequency is very good (you can expect to land a winning combination in about 1 in every 3 spins or so), it is not easy to trigger a multiplier that’s higher than 3x, which is when you can expect to make the most profit!

Most of your base game wins will be small-sized wins, with the occasional larger wins every 20 or so spins. I found the free spins round to be very difficult to trigger!

Prism of Gems maximum win

Prism of Gems boasts of a maximum win potential of 30,000x the bet, thanks to the multipliers that can increase up to 343x. This is more likely to happen during the free spins round, when the multipliers don’t reset to 1x after each spin. 

Prism of Gems has a decent hit frequency, but is highly volatile!

The frequent winning combinations and consecutive wins in Prism of Gems serve to add to the entertainment, however you do have to be aware that most payouts do not make up for the bet size during the base game. It’s all about waiting for those lucky spins or the free spins round, when the multipliers will rise above 2x, since that’s when you’ll make up for previous losses. Just keep in mind that the slot is highly volatile!

Game Features

Prism of Gems incorporates a couple of features that play out during both the base game and free spins, and which are your key to unlocking the biggest wins.

Wilds and other base game features

The diamond-like gem functions as the wild in Prism of Gems, and can only land on the top multiplier reel. When it does, the symbols on the reel below it will all split into 2, which creates more ways to win.

Split Symbols feature

Similarly, if a symbol that lands on the horizontal top reel also lands on the vertical reel below it, it also splits into 2 same symbols. This is known as the Split Symbols feature.

Multiplier Reel

The multiplier reel at the top can feature any of the symbols, which are assigned a multiplier starting from 1x. The value of this multiplier increases each time you get a win on the vertical reel below it, if this win includes the symbol on the multiplier reel above it. This multiplier can go up to 7x for each reel.

You can benefit from more than one multiplier on each spin, given that there are 3 symbols on the horizontal reel that can all be part of a winning combination. This is why, technically, the multiplier can go up to 343x!

Prism of Gems Free Spins

The free spins round in Prism of Gems is triggered if you land 3 or more stained glass scatters. You’ll get 10, 15 or 20 free spins for 3, 4 and 5 scatters respectively.

If there were any multipliers active on the triggering spin, these will be carried onto the free spins. The main highlight of this round is that multipliers won’t reset with a non-winning spin, which means you’re more likely to get to the higher multipliers!

What’s more, if you land one more scatter during the round, you’ll get 2 extra spins to play with!

Prism of Gems offers attractive features, but the free spins round is a tad disappointing

I loved the combination of features in Prism of Gems, and the potential that comes with the increasing multipliers and splitting symbols. However, it does take a good while to trigger the free spins, and I was slightly disappointed with my overall win from the round, which amounted to less than 20x the original stake despite getting a number of extra spins and multipliers – a far cry from the potential 30,000x!

Prism of Gems Graphics & Sound 

Optimized for Mobile👍
MusicYes, plus cool sound effects
Special featuresN/A

Play N Go does a nice job with the design and sound effects

I loved the ambience created in this slot thanks to the sound effects and setting, which both evoke an aura of magic. I also liked the symbols’ light colours and the faded glass dome in the background, which are in such stark contrast to the overly-bright and glitzy symbols you encounter in other games. The stage is well set for a relaxing slot experience, which doesn’t overwhelm your senses with too much glitz!

Solutions if you have some issues with a game

In today’s casinos, you’re not likely to encounter too many issues as long as you have a stable internet connection. That said, here’s a few things you should know just in case:

  • If the game is interrupted as you’re playing for real money, you can usually replay the game round after restarting the game. If not, your previous wins will be added to your balance.
  • If for some reason you don’t receive your previously-accumulated wins, you should contact the casino’s customer support immediately.
  • In the case of malfunction of the gaming software from the provider’s end, all affected bets are refunded and payouts rendered void.


Prism of Gems is quite a delight to play, and one can hardly find fault with the graphics and its overall entertainment factor. I also loved the splitting symbols, and how often these can be triggered, and of course, the increasing multipliers can lead to great rewards, though big wins will still be few and sparse.

That said, the very high volatility of this game should be kept in mind. Free spins don’t get triggered very often, and when they do, you might not land that huge win you might have expected. The potential is clearly there, but the risk-factor is high, so tread with caution!

Playing Prism of Gems with a bonus may help you cut your losses, so it’s one thing to consider if you’re still unsure whether you should try the game for real money.

Other slots to play if you like Prism of Gems slot

There are plenty of gem-themed slots out there that feature free spins and multipliers. You can try out Play N GO’s own Perfect Gems slot, which features a very similar design, cascading wins and multipliers.

Big Time Gaming’s Bonanza also has a similar setup, and features 117,649 ways to win and a horizontal reel at the top.

Finally, you may also like some of the megaways slots by various providers, all of which come with a cascading mechanism and a different number of ways to win on each spin. Most of them feature a volatility level that’s similar to Prism of Gems slot, as well as the multiplier feature.
