Gem Trio Slot

Gem Trio is a fun online slot game that was developed and released by Pragmatic Play in 2025. Pragmatic Play is one of the most popular online slot game developers in the iGaming industry, with an extensive collection of UK online slots under its belt, spanning a diverse range of themes and gameplay styles. With Gem Trio, this studio has created a slot that takes clear inspiration from physical slot machines found in traditional casinos. Gem Trio includes classic symbol designs, gems, straightforward gameplay, and other features that set this title apart from the more modern slots full of varied gameplay mechanics.

Gem Trio Game Background

The base playtable in Gem Trio contains 3 reels and 3 rows; however, on any given spin, between 1 and 3 symbols of different sizes can appear on each reel. This changing reel structure is similar to Megaways slots, which allow for unique layouts on each spin thanks to the Megaways mechanic. Gem Trio contains 9 paylines across its simple structure, with each payline being able to be completed by landing 3+ symbols in a row, starting from the leftmost reel.

Visually, the playtable is contained within a silver metal border, adorned by small gems all the way around the outside and in between each reel. The reels themselves have a silver canvas with shadows along the top and bottom that create a curved effect, mimicking the appearance of physical slots. Above each reel, there is also a different gem, with each gem providing modifiers in the game's free spins round. Finally, the background behind the reels is entirely blue with small particle effects and colourful lights throughout. Some other games which take inspiration from traditional slot games for their design include the likes of Triple Blitz 7s and the Vegas Diamonds slot.

Gem Trio Slot Symbols

All of the symbols in Gem Trio are classic slot symbols found in traditional games and seen all throughout an online casino. These symbol designs include the iconic 7 and BAR symbols, with combinations of symbol types also being able to be used for combinations.

The bonus symbols in Gem Trio are quite simple in terms of design, as firstly, there are wild symbols represented by the word ‘wild’ in varying bold colours. On top of this, there are gem symbols displayed through the use of 3 different kinds of gems.

Gem Trio Bonus Features

Gem Trio contains a couple of interesting bonus features which add to the already entertaining gameplay, without overcomplicating the overall experience, allowing this slot to remain original. The first bonus feature of note included within Gem Trio is the game's wild symbols, which may substitute for any symbols found across the reels, except for the bonus gem symbols. Wilds can appear on all reels during the base and free spins features and assume the value of other symbols to form or extend matching combinations. There is also an x3 multiplier attached to the Wild symbols, which will multiply any combinations they are a part of by x3.

On top of this, there are 3 types of gem symbols that can appear on screen in Gem Trio: emerald, diamond, or ruby. When any of these symbols land, they will be collected by the corresponding gem found above the reels. Whenever this happens, there is a random chance that the free spins round can be triggered, with the corresponding modifier provided by each unique gem in play.

The free spins round itself in Gem Trio starts with 10 free spins and at least 1 of the 3 possible modifiers related to the gem collection, with a combination available if the round is triggered by multiple gems. The following modifiers are available throughout the free spins round:

Emerald modifier - Every emerald symbol that lands provides an additional +1 or +2 free spins, respectively.

Diamond modifier - 4 jackpot prizes become available, namely, mini, minor, major and grand jackpots, which are often found across other jackpot slots. Whenever a diamond symbol lands, it will display one of the available jackpots, and when 4 of a kind land, that jackpot is returned to the player.

Ruby modifier - Free spins feature is played on 2, 3x3 grids, with 10 free spins awarded for each.

Gem Trio Mobile Play

As is the case with many other slots and live casino games, Gem Trio contains the HTML5 software that allows for cross-compatability. As a result of this, players can experience Gem Trio on a range of devices, including smartphones, tablets, PCs, and laptops.
