Goblins and Gemstones Slot Review
Kalamba Games have made a name for themselves by bringing distinctive mechanics to the online slots landscape, and Goblins and Gemstones demonstrates their commitment to innovative design. Released in October 2020, this fantasy-themed adventure on a 5 reels, 4 rows grid operates across 1,024 ways to win, making it immediately appealing to players who prefer dynamic win structures over traditional paylines. The wizarding bank theme, paired with a soundtrack that wouldn’t feel out of place in a fantasy film, establishes an immersive experience from the first spin.
Base Game & Features
The base game establishes itself with a collection meter system that fundamentally changes how standard spins operate. Rather than treating every spin as identical, Goblins and Gemstones introduces three distinctly coloured gem symbols—green, red, and blue—each tied to its own progression metre. Land 20 of any matching gem, and you unlock that gem’s corresponding feature variant, creating a layered progression system that prevents base gameplay from feeling repetitive.
Special Symbols and Feature Triggers
The three gem-linked features form the backbone of the game’s mechanics. Scatter Split (Green Gem) designates a random symbol as your special symbol for that spin, paying anywhere on the reels. Paired Reels (Red Gem) synchronises adjacent reels to show identical symbols across all synced positions, multiplying win frequency during base gameplay. Expand ‘N Lock (Blue Gem) selects a symbol and expands it above the usual reel boundaries, locking those positions to generate additional winning combinations.
The collection metre system ensures base gameplay maintains forward momentum, though it’s worth noting that wins between feature collection thresholds can feel sparse relative to the headline hit frequency of 23.23%. This creates a trade-off between the statistical frequency of wins and their perceived impact during play.
Bonus Features & Free Spins
Landing three scatter symbols triggers the free spins mode, where the game offers genuine player choice. You can elect to receive 7 free spins with Paired Reels, 8 free spins with Expand ‘N Lock, or 10 free spins with Scatter Split. This isn’t merely cosmetic—each feature variant carries different volatility profiles. The Paired Reels option favours frequent, medium-sized wins; Expand ‘N Lock balances frequency with potential; whilst Scatter Split leans toward rarer but more explosive payouts.
The collection metre continues functioning during free spins, meaning that landing the required gems during your bonus round can trigger a secondary feature on top of your chosen spins. This layering creates the potential for exceptionally strong bonus outcomes, particularly when multiple features interact.
Bonus Buy & Ante Bet
HyperBonus is available to eligible players, allowing direct entry into the free spins feature for 49.4x your stake. This accelerates play for those seeking immediate bonus engagement, though it’s important to note that HyperBonus is unavailable to UK-based players due to regulatory restrictions. For those who can access it, the feature increases the base game RTP from 96.30% to 97.10%, providing a measurable mathematical advantage.
Our Honest Verdict
Goblins and Gemstones Verdict: 7/10
Kalamba Games have delivered a technically impressive slot with substantial win potential and innovative collection-based mechanics that distinguish it within the modern casino landscape. The 10/10 volatility rating isn’t hyperbole—this game targets players comfortable with extended dry spells in exchange for potentially life-altering payouts when all elements align, with a stated maximum of 38,890x stake.
The standout positives are clear: the collection metre system genuinely adds progression and engagement to base gameplay, the free spins selection mechanic respects player agency by allowing choice, and the graphics maintain high production standards throughout. The soundtrack creates atmosphere without becoming tiresome.
That said, the game carries notable limitations. Whilst the 23.23% hit frequency sounds respectable statistically, the actual perception during play differs—wins between feature collection thresholds are genuinely sparse due to lower individual payouts. Paired Reels feature, whilst visually distinctive, remains locked in its initial position rather than expanding dynamically. The Expand ‘N Lock feature, though mechanically sound, doesn’t quite match the expanding mechanics found in comparable high-volatility releases.
The 96.30% RTP combined with 10/10 volatility creates a distinctly specific risk profile: you should expect substantial losing streaks interrupted by sudden substantial wins. This game absolutely suits high-volatility chasers seeking genuine win potential, but will frustrate players preferring consistent, predictable returns or those with modest bankrolls unable to weather the volatility swings. Experienced players familiar with extreme variance will find plenty to appreciate; those new to high-volatility gaming should approach cautiously.
