Prism of Gems: Slot Overview

Developer Play'n GO continues their fixation with all things sparkly in Prism of Gems, another in their dynamically expanding precious stones range. Like others that preceded it, Prism of Gems utilises splitting symbols to expand reels and ways, while powering up multipliers in the process to boost wins. It is similar to Frozen Gems and Perfect Gems, but Play'n GO has dialled up the winning potential in an attempt to make Prism of Gems the most tempting of the bunch.

The aforementioned Gem games were attractive without being particularly stunning from a visual standpoint - Prism of Gems continues this trend. The 5-reel game grid is quite plain to look at, covered in regular card royals and gems as it is, though the background image creates an agreeable atmosphere. With its semi-circular Greco-Roman pillars and iron/glass dome letting in light, it feels like we’re in a museum of sorts. Not one of the majors like the Louvre or the British Museum, but one of those smaller elegant buildings hidden deep in a travel book that only locals know about. It might not house anything as impressive as a Rosetta Stone, yet its eclectic collection is nevertheless full of quirky surprises. Anyway, it’s a pleasant place to be and makes Prism of Gems warmer than Frozen Gems in almost every regard.

Spinning gems once again is possible on any device, where bets from 20 p/c to £/€100 per spin can be set. Prism of Gems is a highly volatile game, officially rated as 9 out of 10, and comes with a default RTP value of 96.24%. As always, be aware the game may ship with a lower value of 94.25%, or less, depending on the market, so be on the lookout for that.

At the start of every paid spin, the reels are arranged in a 3-4-4-4-3 configuration, expanding at most to 3-7-7-7-3 via a splitting symbol mechanic covered below. Ways to win are variable as well, starting at 576, rising to 3,087 at full strength. In all grid states, wins are awarded when 3 to 5 matching symbols land adjacently from the leftmost reel. The symbols themselves are split into low pay card icons 9-A and higher value gems. There are 4 of the latter higher-paying lot, where a combination of 5 gems is worth 1.4 to 3 times the stake. Factor in the number of ways plus some impressive multipliers, and those values quickly blossom.

Prism of Gems: Slot Features

Central to these gem-themed games is a cascade feature, working in tandem with splitting symbols and multipliers. Every win triggers the cascade mechanic, which removes the combination from the game grid so non-winning symbols can drop down to plug the gaps. Cascades roll on until no new winning combinations appear.

The top row, sitting on reels 2-4, is called the multiplier reel, and each of its positions has a multiplier attached to it – starting at x1. Every time the corresponding reel cascades, the multiplier increases by +1 up to x7. Any wins with symbols present on the top row are affected by the multiplier, which can accumulate up to x343. In addition, if a symbol matches the one in the multiplier reel above it, it splits into 2 up to 7 positions high at most. In addition, wilds split all symbols below them, except scatters. Wilds substitute for any symbol except scatters, by the way.

Scatters land on any row to award 10, 15, or 20 free spins when 3, 4, or 5 of them are in view. All active multipliers from the base game are carried over to the bonus round, where they build progressively until the end of the feature, not resetting between free spins. During the feature, each scatter awards +2 additional free spins.

Prism of Gems: Slot Verdict

Prism of Gems takes elements of the previous two games, then builds on them to create a higher-performing slot. So far, all have used splitting symbols of some description, while Prism of Gems' multiplier system is more sophisticated than Perfect Gems. That one incremented its multiplier following cascades, some might say to cash in Bonanza's success. The result shrugs off the kid's movie connotations Frozen Gems had while putting extra distance between itself and Bonanza. Prism of Gems is definitely not a complete standalone game but an evolution of the series.

For whatever reason, Play'n GO's gem range is still to knock it out of the park. If winning potential is one reason, then the team has gone a long way to destroying that argument. Prism of Gems might have lopped off a reel compared to Perfect Gems, yet it has significantly increased payout possibilities, where wins of up to 30,000 times the bet are now possible – much higher this time around. Will it be enough to make up for the perceived shortcomings in other areas? Possibly for players whose overriding concern is to go as large as possible. Having said that, don't stare yourself blind on PnG's advertised max wins as it seems extremely rare to hit even anything near it in most of their slots - as is evident if you keep track of big wins shared on social media.

Setting the radically higher max win figure to one side, its business as usual with the rest of Prism of Gems. Splitting symbols open up the game board, yet not as dramatically as PopWins games do if you're after a contemporary comparison. So while it is similar to the two games that preceded it, Prism of Gems uses larger amounts of just about everything to push the range to a higher level. Play'n GO has thrown in the proverbial kitchen sink in the form of massively increased potential, which is a bonus, though the core gaming remains more or less the same as what came before.


Prism of Gems is essentially more of what came before.
