Allow me to introduce you to the Gem Trio slot, which doesn’t boast modern, elegant visuals or a trailblazing storyline.

The Gem Trio Slot Game

Pragmatic Play has been in the slot production industry for a long time. So, I assume that, to them, blending a classic slot with modern mechanics and features shouldn’t require too much effort.

Just like that, Gem Trio came into existence, establishing itself on a 3x3 playing field. Like most other retro-styled slots, it makes use of a less advanced display, transporting you straight to the doorstep of the yonder days.

Although the background is dull in the base game, it becomes brighter and colourful during the free spins. To wrap up the design, you get to enjoy a fast-paced melody accompanied by upbeat sound effects that make every spin feel energetic.

Symbols and Payouts

Exploring deeper into the gameplay should expose you to five regular symbols that can create up to seven winning combinations. Oh, it’s also worth mentioning that you win on nine fixed paylines.

Therefore, you complete a winning combination when identical symbols appear from left to right on 3 adjacent reels and active paylines from the furthest left column.

The low-paying symbols in Gem Trio are the Single and Double BAR signs, as they pay 0.5x and 1x the stake, respectively. Then again, you can complete a combination with any of them and receive 0.3x the bet.

The Single, Double, and Triple 7 are the premiums, and they give out 2.5x, 4x, and 7x the bet. When any of them complete a combination, it’s worth 1x the stake.

Gem Trio Slot Bonus Features

Nothing about the features in this game is beyond comprehension. It includes special multiple symbols, free spins, and bonus buys!

Wild Symbols

The Gem Trio features 3 wilds (Green, Red, and 3x), and they all appear on all reels in the base game and free spins. Their purpose is to substitute for all the symbols except the Gem symbols. Furthermore, a complete line of green, red, and 3x wilds awards 50x, 125x, and 250x the bet, while a combo of all of them pays 15x the stake.

The 3x wild multiplies the win of all the paying sequences it’s a part of, apart from wild combinations.

Gem Symbols

Whenever the Emerald, Diamond, and Ruby Gems appear, they accumulate into their respective pots above the Gem Trio grid. In return, they can randomly trigger the free spins with a respective modifier triggered at random.

The collection happens after the spin, and if you trigger the free spins, 1 to 3 of the respective modifiers will be randomly activated.

Free Spins

This feature starts with 10 free spins and at least one of the following modifiers related to the Gem collection:

  • Emerald - this modifier causes all the Emeralds that hit to award +1 or +2 additional spins.
  • Diamond - this modifier avails the Mini (20x), Minor (50x), Major (300x), or Grand (10,000x bet) prizes for winning. Every Diamond Gem that appears displays a bonus prize, which accumulates into the name’s prize. Collecting four identical names earns you the corresponding bonus prize.
  • Ruby - causes the free spins to be played on two 3x3 grids, with each getting 10 free spins. Any additional free spins awarded by the Emerald Gem when the modifier is also active will be awarded for the grid on which the gem appears.

Bonus Buys

The Gem Trio lets you trigger the free spins round from the base game, as follows:

  • Paying 50x bet guarantees one of the three modifiers will randomly activate.
  • Paying 100x bet triggers the free spins with any two modifiers guaranteed at random.
  • Paying 200x stake guarantees that all three modifiers will be activated.

How to Win at Gem Trio Slot

This video slot operates on a 3x3 grid, with its backbone being 9 paylines. In other words, it’s a pretty familiar configuration within the iGaming scene.

Wins happen when 3-of-a-kind symbols appear on adjacent reels and along predefined paylines from the leftmost reel. Furthermore, the payouts can be boosted by a 3x wild, which multiplies wins of combinations it helps to complete.

A Gem Trio spin costs from €0.10 to €250. You play a single round by tapping the Spin button or several auto-spins through the Autoplay function. You can also use the Space and Enter buttons to start and stop a spin.

Gem Trio Slot RTP & Volatility

With a solid RTP of 96.50%, this game is highly volatile and can award up to 20,000 times your bet! However, the RTP values vary when using the buy feature.

The Conclusion

The Gem Trio by Pragmatic Play is one of the online slots that straddles the line between modern and classic experiences. Since the design is pretty standard in the iGaming world nowadays, it’s not unique in that regard, and whether it’s worth your hard-earned money depends on your desires.

One of the things worth appreciating about this game is its straightforward nature. No complicated mechanics and/or features. Furthermore, the free spins feature is enhanced by gem modifiers, making it even more enticing. It’s in the bonus rounds where you can unlock significant money rewards, reaching up to 20,000x bet.

On the other hand, this Pragmatic Play release felt bland, especially during the base game, as the only added feature was the 3x wild. Moreover, the theme didn’t feel unique, and players who prefer more in-depth gameplay may find this high-volatility slot dry. Therefore, in my opinion, while it has potential, I wouldn’t spend hours grinding on it.
