Set against an old-school playing grid in space, Gem Trio is accompanied by a jazzy soundtrack and a commentator who reacts to each Gem Symbol landed. The game is designed with shiny symbols and sparkling sound effects that can either delight players or become overwhelming after several spins. It is compatible with most desktops, mobiles, and tablets, and wins are achieved by landing three matching symbols on adjacent reels, starting from the leftmost reel.
The lower-paying symbols consist of two types of BAR symbols: the single BAR symbol and the double-stacked BAR symbol. Achieving a win with three matching symbols yields payouts ranging from 0.3X to 1X the bet. The higher-paying symbols are the 7s, which include the single 7, double 7, and triple 7. Winning with three of the same 7 symbol pays out between 1X and 7X the bet. Additionally, a variety of Gem Symbols serve as Scatters and different Wild Symbols, which are detailed in the following section.
What is the max win in the slot Gem Trio?
The maximum win available in Gem Trio is up to 20,000X the bet.
What features are available in the slot Gem Trio?
The features include Wild Symbols, Free Spins, and Feature Buy options.
There are three types of Wild Symbols that assist in creating winning combinations by substituting for all other paying symbols. The Green and Red Wild Symbols function as regular Wilds, differing only in their payout values. The 3X Wild enhances the win of all winning combinations it is part of by 3X, except for combinations exclusively made up of Wilds.
The Free Spins feature can be triggered by collecting one of three types of Gem Symbols. Upon activation, players receive 10 initial spins along with one or more bonuses based on the Gem Symbols that activated the feature.
Emerald Modifier = This modifier awards 1 or 2 extra Free Spins for every Emerald Gem that appears during the bonus round.
Diamond Modifier = This modifier links each Diamond Gem to one of four Jackpots displayed next to the reels. Collecting four Diamonds with the same Jackpot name awards that prize, ranging from 20X to 10,000X the bet.
Ruby Modifier = This modifier allows the Free Spins feature to be played on two 3×3 grids, with 10 spins allocated to each grid.
If the Free Spins feature is activated with more than one type of Gem Symbol, the modifiers will be mixed, allowing for an enriched bonus game experience.
The base game offers three Feature Buy options, letting players activate the Free Spins feature immediately for a cost based on their current bet.
50X = Triggers the Free Spins feature with one randomly chosen modifier.
100X = Activates the Free Spins feature with two of the three modifiers chosen randomly.
200X = Initiates the Free Spins feature with all three modifiers active.
Visually, Gem Trio differentiates itself from most recent releases, even among Pragmatic Play’s own newer titles. The classic graphics and theme complement the gameplay, indicating that this was likely the intent from the beginning. While older games may appeal to a specific niche, they offer a unique experience compared to many modern options with their vibrant graphics, distinctive themes, and innovative features. Nevertheless, there is certainly room in the market for such games, allowing both veterans and newcomers to experience the essence of traditional casino gaming, particularly with updated statistics and a sizable max win of 20,000X the bet.
Regarding the gameplay, the game presents modern statistics, including an RTP of 96.5%, a hit frequency of 27.85%, and a respectable maximum win. However, it does come with a low hit probability of 1 in every 27,247,956 spins. When it comes to features, there is primarily the Free Spins feature. Although the different Wild Symbols provide some variety, two of them are essentially the same with differing payouts, while the third functions as a multiplier for already low-paying symbols. The Free Spins feature, along with its three modifiers, can be very rewarding. Each modifier brings a unique advantage, whether it be additional spins, the potential for significant jackpots, or the chance to play on a second grid. Successful bonus games truly shine when activated with multiple modifiers. For those seeking big wins, the Free Spins with three modifiers are the ideal choice. Additionally, for players who wish to bypass the standard base game, the Feature Buy option provides three ways to access the bonus games instantly. Whether you are a fan of classic games or looking for a straightforward experience, consider trying the demo of Gem Trio alongside many other available games.
Gem Trio offers a volatile bonus game featuring three modifiers for players to combine creatively.
