Triggers instant cash prizes from the jackpot tiers. Can award Mini at 20x, Minor at 50x, Major at 300x, or the Grand prize at 10,000x your bet amount.
Activates the dual grid system where you play simultaneously on two separate 3x3 grids, effectively doubling your chances to land winning combinations on every single spin.
Gem Trio introduces a revolutionary three-modifier mechanic that transforms the standard slot experience. Each gem symbol serves a distinct purpose during the free spins feature, creating dynamic gameplay where no two bonus rounds play identically.
The emerald modifier extends your session by adding spins, the diamond modifier injects instant cash wins from the prize panel, and the ruby modifier doubles your playing field. When you purchase the bonus with all three modifiers active, you experience the full potential of this mechanic simultaneously.
This system creates a high-volatility environment where patient players can trigger massive multipliers. The 20,000x maximum win becomes achievable when ruby's dual grids combine with diamond's Grand prize potential and emerald's extended spin count.

The triple seven symbol serves as the premium regular pay in Gem Trio, offering £14.00 for three of a kind on a £2.00 bet. More importantly, any combination of 777 symbols across the nine paylines awards £2.00, making it the most frequent high-value payout during base game sessions.
The BAR symbols follow a similar pattern with any combination pays at £0.60, creating consistent small wins that maintain your balance during the hunt for the free spins trigger. This dual-tier payout structure on both 777 and BAR symbols distinguishes Gem Trio from traditional three-reel slots.
Wild symbols carry substantial standalone value, with the 3X variant paying £500.00 for three of a kind whilst also applying a triple multiplier to any winning combination it completes. This multiplier becomes particularly powerful when combined with 777 symbols, potentially turning a £14.00 win into £42.00 instantly.
Gem Trio offers three distinct purchase options for immediate entry into the free spins feature. Each option activates a different number of modifiers, fundamentally altering the mathematics and potential of your bonus round.
The RTP variance across the three purchase options remains remarkably tight, fluctuating only 0.02% between the lowest and highest. This indicates that Pragmatic Play has balanced the cost-to-value ratio carefully across all three tiers.
The three-modifier option at £400.00 represents 200x your base bet, providing guaranteed access to the ruby dual grid, diamond instant prizes, and emerald extra spins simultaneously. This creates the highest variance scenario where extreme wins become more probable despite the marginally lower 96.49% RTP.
For players seeking maximum win potential, the three-modifier purchase offers the clearest path to the 20,000x maximum. The dual grids from ruby double your chances to land diamond prizes, whilst emerald extends the session to capitalise on hot streaks.
Gem Trio operates in the high volatility category, meaning extended dry spells punctuated by substantial wins characterise typical sessions. The 96.50% base RTP sits comfortably within industry standards, but the true mathematical interest lies in the modifier interactions during free spins.
When ruby activates dual grids, you effectively play 18 paylines simultaneously across two independent 3x3 layouts. If diamond triggers during this state, you can win instant prizes on both grids. Stack emerald into this equation, and your 10 base spins can extend to 15 or more, multiplying your exposure to these doubled opportunities.
The maximum win of 20,000x becomes achievable through a perfect storm: ruby dual grids active, multiple diamond Grand prizes at 10,000x each, combined with wild multipliers on premium 777 symbols. Whilst statistically rare, this combination exists within the game's mathematical model.
Given the high volatility profile, bankroll management becomes critical. The minimum £0.10 bet allows for 1,000 spins on a £100 bankroll, providing adequate runway to encounter the free spins trigger naturally. The bonus buy at 100x-400x bet requires significantly deeper pockets.
Players should calculate their bonus buy budget based on the three-modifier option if pursuing maximum win potential. At £250 maximum bet, the three-modifier purchase costs £100,000, placing it firmly in high-roller territory. Most players will find optimal value between £0.50-£5.00 bets, where bonus buys range from £50-£2,000.
The any-combination pays on 777 and BAR symbols provide crucial base game sustainability. These frequent small wins reduce the effective volatility during regular play, making the wait for free spins more tolerable than pure scatter-trigger slots.
Gem Trio bridges classic three-reel fruit machine aesthetics with modern bonus mechanics. The 777 and BAR symbols evoke nostalgia, whilst the gem modifier system introduces contemporary complexity. This hybrid approach appeals to both traditional slot enthusiasts and bonus-hunting players.
The metallic frame with 42 rivets surrounding the grid references physical slot machine construction, creating visual familiarity. However, the cosmic background with bokeh effects and particle systems firmly plants the game in the digital realm, allowing for effects impossible in mechanical slots.
Pragmatic Play has effectively modernised the fruit machine formula without abandoning its core appeal. The 3x3 grid maintains simplicity, the symbol set remains recognisable, but the modifier system and 20,000x potential elevate the game beyond retro homage into a mathematically sophisticated product.
Gem Trio implements keyboard shortcuts for efficient gameplay. Hold the spacebar to activate turbo spin mode, dramatically accelerating spin speed for players who prefer rapid-fire sessions. Press Enter to initiate a standard spin without reaching for the mouse.
The colour-coded prize panel uses distinct hues for each tier: red for Grand, purple for Major, green for Minor, and light blue for Mini. This colour differentiation aids quick recognition during fast-paced bonus rounds when multiple prizes trigger in succession.
All symbols feature clear text alternatives. The 777 and BAR symbols use bold typography with metallic gradients and gold borders, ensuring visibility against the dark cosmic background. Wild symbols display their multiplier values prominently, eliminating ambiguity about their function.
The background employs a deep indigo gradient with 200-250 white stars at 1-2 pixels each, creating a cosmic jewellery display aesthetic. Four bokeh spots in purple, pink, blue, and light blue positions add depth through simulated depth-of-field blur effects.
Each gem sits atop a cylindrical grey gradient pedestal, mimicking museum display cases. The emerald uses an octagonal cut at 80x100 pixels with light green centre and dark green edges. The diamond features brilliant cut faceting at 100x80 pixels with sky blue colouration and white highlights. The ruby employs an oval cut at 70x90 pixels with scarlet centre transitioning to burgundy edges.
This attention to gemstone rendering extends the luxury theme beyond mere graphics into a cohesive visual identity. The gems aren't simply scatter symbols; they're the thematic centrepiece that justifies the game's title and modifier system.
