Gem Trio Overview

Gem Trio is a high volatility video slot developed by Pragmatic Play. Played on a 3-reel layout with 9 fixed paylines, the game is built for those who prefer a more traditional format. In addition, it features an RTP rate of 96.50% and offers betting options starting from €0.10 up to €250.00 per spin. While gameplay is relatively simple, the slot includes the potential for a maximum payout of up to 20,000x the stake, placing it firmly in the high-reward category.

Gem Trio Theme

Gem Trio Theme

Gem Trio features a gem-inspired theme set against a dark blue sky sprinkled with stars and soft galactic touches, giving it a simple appearance. The 3×3 reel setup draws on classic slot design, using familiar symbols like BARs in single and double forms, as well as sevens in singles, doubles, and triples.

Additionally, the soundtrack is subtle and well-matched to the visuals, supporting the theme without becoming distracting. Together, the elements create a straightforward and familiar presentation.

Bonuses & Features

Gem Trio Free Spins

Wild Symbols: Wild symbols can appear on any of the 3 reels during both the base game and the Free Spins round. They substitute for all standard symbols except for the Gem symbols. When a win is formed with 1 or more Wilds, excluding those made up entirely of Wilds, the payout is multiplied by three.

Gem Symbols: Three types of Gem symbols can land during play: Emerald, Diamond, and Ruby. When any of these appear, they are collected in their respective trackers positioned above the reels. At the end of a spin, there is a chance for the accumulated gems to randomly trigger the Free Spins round, activating one, two, or all three modifiers, depending on which gems were collected.

Gem Trio Bonus

Free Spins: Once activated, the Free Spins round begins with 10 spins. The modifiers in play depend on which gem types were involved in the trigger.

  • Emerald Modifier: Every Emerald Gem that lands during the round randomly grants an additional 1 or 2 Free Spins.
  • Diamond Modifier: This modifier introduces four jackpot-style rewards: Mini – 20x, Minor – 50x, Major – 300x, and Grand – 10,000x the total stake. Each Diamond Gem shows one of the prize names and is stored under the matching prize category. Once four of the same prize have been collected, that reward is paid out.
  • Ruby Modifier: This feature opens two 3×3 reel sets for the duration of the Free Spins, with each grid receiving 10 spins. If the Emerald Modifier is also active, extra spins triggered by Emerald Gems are applied only to the grid where the gem appeared.

Gem Trio Buy Bonus

Buy Free Spins: Players can also access the Free Spins round directly by using the Buy Feature from the base game. There are three purchase options:

  • 50x the total bet: Triggers Free Spins with one random modifier.
  • 100x the total bet: Triggers Free Spins with two random modifiers.
  • 200x the total bet: Triggers Free Spins with all three modifiers active.

Conclusion

Gem Trio is a simple, high-volatility slot with a classic layout and a few added features to keep things interesting. The combination of Wilds, gem-triggered modifiers, and the Free Spins round offers some potential for larger payouts, particularly with the jackpot prizes and dual-grid setup.

Furthermore, its clean presentation and straightforward mechanics make it accessible, while the 20,000x max win may suit players seeking high returns from compact gameplay.
