Gemstones Gold Slot Review
The underground mining theme meets precious gems in PG Soft's latest creation, where multiplier mechanics take center stage. This high-volatility slot operates on a 6x5 grid with collapsing reels, offering players the chance to unlock multipliers up to x500 during regular spins.
Core Mechanics and Multiplier System
The game's defining feature revolves around its multiplier reel positioned beneath the main grid. Three multiplier symbols appear randomly at the start of each spin, ranging from x2 to x500, each covered by three blockers. When winning symbols land above these multipliers, one blocker gets removed. Successfully clearing all three blockers reveals the multiplier, which then applies to that spin's total win.
During free spins, this system becomes more generous. Six multiplier symbols appear instead of three, and they only require two blockers to be removed. More importantly, revealed multipliers persist between spins, accumulating until they combine with the next winning free spin's multiplier.
Symbol Values and Winning Combinations
The paytable features eight regular symbols, requiring clusters of 8 or more matching symbols anywhere on the reels for a win. Here's the complete payout structure for maximum clusters:
| Symbol Type | 8-9 Symbols | 10-11 Symbols | 12-14 Symbols | 15+ Symbols |
| Gold Nugget | $20 | $40 | $80 | $200 |
| Ruby | $10 | $20 | $30 | $60 |
| Amethyst | $10 | $20 | $30 | $60 |
| Sapphire | $5 | $10 | $15 | $30 |
| Emerald | $5 | $10 | $15 | $30 |
| Bronze Ore | $5 | $8 | $10 | $20 |
| Pink Stone | $3 | $5 | $8 | $20 |
| Blue Stone | $3 | $5 | $8 | $20 |
Free Spins Feature Details
Three scatter symbols trigger 10 free spins, with each additional scatter adding 2 more spins. The Gemstones Gold demo showcases how dramatically the enhanced multiplier mechanics can impact wins during this bonus round. Landing two scatters during free spins awards 5 additional spins, allowing for extended bonus sessions.
The feature buy option costs 75x your stake, providing direct access to the free spins. This represents approximately 3,750 times the minimum bet when playing at the lowest stake level.

Distinctive Elements Worth Noting
The collapsing reel mechanism creates chain reaction opportunities after each win. Winning symbols explode and disappear, allowing symbols above to cascade down. This process continues until no new winning combinations form, potentially leading to multiple wins from a single paid spin.
Key strategic considerations include:
- Multipliers only activate when winning symbols appear directly above them
- The multiplier reel refreshes with each new spin in the base game
- Free spins maintain multiplier values between spins for compound effects
Comparison with Similar Games
Unlike Goblins & Gemstones, which focuses on traditional payline structures, this slot embraces the modern cluster pays approach. The persistent multiplier mechanic during free spins creates more explosive win potential compared to standard cascading slots.
Technical Specifications and Platform Support
The demo Gemstones Gold version runs smoothly across all major platforms, optimized for a 19.5:9 aspect ratio display. The game supports bet levels from 1 to 10, with three distinct bet size options (0.01, 0.1, 0.5) providing flexibility for different bankroll sizes.
Performance highlights include:
- Full HTML5 compatibility ensuring seamless browser play
- Turbo spin option for faster gameplay sessions
- Auto-spin functionality with loss and win limits
Verdict on Gameplay Experience
The Gemstones Gold slot succeeds in creating tension through its blocker removal system. Each winning cluster brings you closer to revealing potentially game-changing multipliers. The base game maintains engagement with its 35% hit rate, while the free spins deliver the explosive potential players seek in high-volatility slots.
The maximum win cap of 7,500x stake triggers automatically when reached, ending the current spin. This safety mechanism protects both players and operators while still offering substantial winning potential. The combination of cluster pays, cascading wins, and escalating multipliers creates a mathematically sound and entertaining package that stands out in PG Soft's portfolio.
