Gemstone is a Pragmatic Play video slot built on a 3 x 3 grid with five fixed paylines, stacked regular symbols, Wild substitutions and a separate multiplier reel reaching 15x.
Stacked gems determine the base line result first, then a fourth reel scales every qualifying win without changing the symbol grid.

Stacked Gems Feed a Fourth Reel
Stacked gem symbols fill a three-reel, three-row grid evaluated across five fixed paylines. Gem symbols appear stacked, and the Wild substitutes for eligible regular icons, so one reel can contribute the same symbol across several vertical line positions.
Once the main grid is complete, a fourth multiplier reel determines a value that can reach 15x. The selected factor applies to all qualifying line wins from that result but does not alter the underlying symbol arrangement.
No separate bonus round or persistent modifier is confirmed in the feature set. The multiplier and stacked grid settle together, then both reset, leaving the next paid spin independent from the previous fourth-reel outcome.
Multiplier Values Scale Completed Lines
- Gem stacks: Repeated symbols can cover multiple vertical payline positions.
- Wild role: Wild substitutions help complete eligible fixed-line combinations.
- Fourth reel: One separate reel selects the result multiplier.
- All wins: The chosen factor applies across qualifying line awards.
- 15x factor: A high multiplier still requires a base win.
- Full reset: Grid and multiplier clear after each settled round.
Small Grid Restricts Multiplier Conversion
Payout concentration depends on a stacked line win coinciding with a larger fourth-reel factor. The multiplier does not pay by itself, and a 15x display has no value when the 3 x 3 grid produces no qualifying combination.
The confirmed x375 ceiling limits the total-bet result despite multiplier values reaching 15x. Five paylines reduce the number of simultaneous routes, so broad stacked coverage still needs exact left-to-right connections on the compact grid.
The listed medium volatility sits beside a $100 maximum stake and immediate multiplier resets. Because each factor resets immediately, a sequence of high multiplier displays does not create stored value, and changing stake size cannot carry one factor into a later spin.
Player fit and limitations
- Stacked grid: Suits players reading vertical coverage on five lines.
- Fourth factor: Suits players separating symbol wins from multiplier scaling.
- No bonus: No separate free-spin sequence is confirmed.
- Reset factor: Every multiplier clears after the current result.
Consecutive multiplier displays can encourage extending play for another 15x result.
Stop at the preset session time regardless of the reel value.
