Slot Summary

May 30, 2019 marked Play'n GO's release of Perfect Gems, a six-reel game that replaces static ways with Cascading wins, expanding middle reels, and a Multiplier that rises through consecutive removals. The unusual horizontal reel can split matching symbols beneath it, creating as many as 21609 ways. Perfect Spins preserve the accumulated Multiplier, shifting the high-volatility game from short cascade chains toward a longer Free Spins sequence.

How It Plays

Winning combinations use adjacent reels, after which the contributing symbols disappear and replacements fall into the open spaces. Each refill can create another evaluated result.

The horizontal reel affects the second through fifth reels. When its symbol matches the one immediately beneath it, that vertical position divides and increases the available Multiway combinations.

Theme & Atmosphere

Gems dominate the Fantasy presentation, turning each reel expansion into the visual splitting of a valuable object rather than a mechanical change without context.

Magic provides the explanation for symbols dividing and falling again. The History tag is secondary here, since the strongest visual idea is transformation within a jewel display.

Fantasy Magic History Gems

Features & Win Potential

Cascading removes each winning combination before new symbols arrive, while the Multiplier increases by one for every consecutive win inside the same paid spin.

Multiway evaluation and substitution symbols interact with the expanding middle reels, allowing a horizontal match to create additional positions and raise the total number of possible combinations.

Bonus & Free Spins

Perfect Gem Scatter symbols trigger Perfect Spins, with more triggering Scatters awarding more Free Spins. Spin Scatters appearing during the round add two further spins.

The active Free Spins Multiplier carries over from the triggering base spin and does not reset between cascades, so consecutive wins can continue increasing it until Perfect Spins end.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (94.50%), with wins capped at its top multiplier (5,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.

01How do the reels expand in Perfect Gems?

A symbol on the horizontal reel can match the symbol directly below it, causing that position to split and increasing the height of the middle reels.

02What happens to the Multiplier after a cascade?

Each Cascading win raises the Multiplier by one during the base spin. It normally resets afterward, but Perfect Spins carry its value into the feature.

03How are Perfect Spins triggered?

Three or more Perfect Gem Scatter symbols trigger Perfect Spins. Extra Scatter symbols on the triggering result increase the awarded number of Free Spins.
