Slot Summary

Place a stake and let the upper reel determine which gems split in Prism of Gems. Play'n GO's third Gem Series title follows Perfect Gems and Frozen Gems, continuing the family's shared symbol-splitting idea. Its extra reel has an unusually active role: it changes the field below while also contributing symbols to winning combinations.

How It Plays

Winning symbols disappear and replacements cascade into the empty positions. Another winning combination continues that sequence, so a paid spin can produce successive results before the reels finish resolving.

When an ordinary symbol matches the symbol directly above it on the horizontal reel, it splits into two. A wild there splits eligible symbols throughout the corresponding vertical reel.

Features & Win Potential

Each position on the multiplier reel starts at 1x and rises when its corresponding vertical reel cascades. Individual values can reach 7x, with combined multipliers reaching 343x.

The multiplier is selective: a winning combination must include a symbol on the horizontal reel to receive its boost. A displayed multiplier does not automatically apply to every win.

High volatility Free Spins Increasing Multipliers Multiplier Scatter Symbol Wild Symbol Cascading 5 Reels Expanding Reels RTP range Avalanche Free Spins Multiplier Splitting Symbols

Bonus & Free Spins

Landing 3, 4 or 5 scatters awards 10, 15 or 20 free spins, respectively. Existing multipliers carry into the feature and remain between spins, while each further scatter adds 2 spins.

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 (94.25%), with wins capped at its top multiplier (30,000×).

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.
