Ternion (Play'n Go) Slot Review

Ternion: Slot Overview 

With a title inspired by the word “ternion”—meaning a group of three—Ternion by Play’n GO brings a trio of superheroes into the online slot spotlight. Released on June 8, 2023, this high-volatility game trades ancient temples and mystical beasts for capes, crystal shards, and futuristic skylines. Here, players join three ambiguous heroes (or are they villains?)—a fire-blazing man, a blade-wielding woman, and an ice queen—on a mission to trigger wild modifiers, build multipliers, and unlock Doomsday Free Spins. 

Operating on a 5×4 reel grid with 20 paylines, Ternion’s structure is fairly straightforward, but its strengths lie in the layered bonus mechanics, superpowered modifiers, and a sleek audiovisual design that flirts with comic book energy. While the backstory remains vague, the gameplay is anything but, delivering fast-paced spins, powerful visuals, and a maximum win potential of 11,111x your stake—though with a hit probability of less than 1 in 100 million, it’s more aspiration than expectation.

Design and Graphics 

Ternion doesn’t hold back in terms of visuals. The background is a moody, cyber-urban cityscape filled with towering skyscrapers and ominous storm clouds. It’s not quite Gotham or Metropolis, but it clearly evokes those moody comic-book city vibes. The three central characters—unofficially dubbed Ice Lady, Blade Lady, and Fire Man—stand fully animated on the reels, looking like they’ve walked straight off the pages of a futuristic superhero saga. The reel set is outlined with metallic trims and glowing accents, and the overall aesthetic leans heavily into sleek, polished graphics. High-paying symbols include the three heroes and a glowing crystal, while lower-paying icons are standard 10–A royals, stylized with an angular sci-fi font. 

The wild symbol (a glowing golden ‘V’) and scatter (a watch-like disk) complete the symbol set, with crisp animations and satisfying effects when they land. While it’s not the most narratively detailed slot, the atmosphere is engaging and polished from top to bottom.

Gameplay Mechanics 

Ternion is a 20-payline slot set across 5 reels and 4 rows. Wins are awarded for matching symbols from left to right, with a minimum of three needed to trigger a payout. The volatility is rated 9/10, meaning that dry spells are expected, but the rewards can be explosive—especially when the features start syncing together. 

The base game is powered by two key features: 

Hero Modifiers (randomly triggered during the base game) 

Doomsday Free Spins (triggered by landing 3+ scatters) 

Each hero modifier is tied to one of the game’s protagonists, who unleash their powers randomly during base gameplay: 

Ice Shards: 3 to 10 random wilds are placed on the grid 

Blade Flurry: Low-paying symbols are removed; high pays drop to replace them 

Pillars of Flame: Turns 1 to 4 reels fully wild 

These enhancements can trigger at any moment, and while they don’t activate frequently, they inject bursts of excitement when they do—especially the Pillars of Flame, which can blanket the screen in wilds for massive payouts.

Sound and Music 

The soundtrack in Ternion matches the visuals well, albeit with a few hits and misses. During base gameplay, the music leans into tense, synth-laden ambience, which feels appropriate but occasionally underwhelming. When the Doomsday Free Spins begin, the tempo ramps up with a faster beat—though the “epic” factor is somewhat dulled by a slightly tinny, flat sound mix. 

Sound effects, however, are spot-on. Wilds whoosh into place with a burst of energy, and character features are accompanied by satisfying impact sounds and subtle voiceovers. The hero theme isn’t quite on par with the big-screen Marvel energy it emulates, but it still does a solid job of creating atmosphere. 

Overall, the sound design complements the game’s futuristic superhero motif, even if it doesn’t elevate the experience in quite the way some might expect.

Bonus Features 

Hero Modifiers 

As mentioned earlier, each hero brings a unique modifier to the base game: Ice Shards (Ice Lady): Adds 3–10 wilds randomly 

Blade Flurry (Blade Lady): Clears low symbols for high pays to drop in 

Pillars of Flame (Fire Man): Converts 1–4 reels entirely to wilds 

These modifiers can be triggered at random during the base game or appear more frequently and powerfully in the bonus round. 

Doomsday Free Spins 

This is the primary feature and can be triggered by landing 3, 4, or 5 scatters, awarding 8, 10, or 14 free spins. During the free spins: 

Hero modifiers become stronger and more frequent 

Wilds stacked on top of each other increase a win multiplier by +1 

Crystal symbols are collected, and every 5 crystals trigger enhanced hero powers 

It’s possible to retrigger the free spins by landing 3 or more scatters again during the bonus, with a maximum of 38 total free spins possible. 

The crystal collection mechanic gives players a secondary goal beyond just hitting big wins, as it unlocks more powerful supermoves from the heroes once enough have been gathered. When everything lines up—multipliers, modifiers, wilds—it can lead to electric sequences of chain wins.

Betting Options and Payouts 

Ternion caters to a wide range of players with a betting range from €0.20 to €100 per spin. The paytable is broken down as follows: 

10–A symbols: Pay 1.5x to 2.5x for five of a kind 

Crystal, Ice Lady, Blade Lady, Fire Man: Pay 5x to 50x for five of a kind 

Wild symbol: Pays the same as the Fire Man and substitutes for all but the scatter 

With an RTP of 96.20% and a very high volatility model, this game is not for the faint of heart. The top payout of 11,111x the stake is significant, but the hit frequency is lower than 1 in 100 million, so players should manage expectations accordingly. 

For the most part, wins in the base game are modest unless a hero feature triggers. The real thrills come during the Doomsday Free Spins, especially if multipliers start to build and reels go wild.

Conclusion 

Ternion is a polished, superhero-themed slot that brings together slick visuals, fast-paced mechanics, and layered features without overcomplicating things. While the lore behind the characters remains vague, the gameplay mechanics are clear, and the hero modifiers are a lot of fun when they show up—especially during free spins. 

Its high volatility, combined with a limited payline structure (20 lines), can make the base game feel slow at times. However, it delivers on its promise once the bonuses activate—particularly when wild reels stack up and multipliers begin to climb. And when all the features fire in sync, it’s easy to see how this slot can deliver those rare 11,111x moments. 

On the flip side, Ternion doesn’t break new ground in terms of slot innovation. It feels a bit like a hybrid of Moon Princess, Rise of Olympus, and Fire Joker, dressed in a superhero costume. Still, it’s stylish, clean, and offers enough engagement for players looking for mid-length sessions with feature-driven spikes of excitement. 

In short, Ternion is a flashy slot with just enough firepower to make it worth a spin or two—especially for fans of modern comic-style visuals and those chasing dream-sized multipliers with big-bang volatility.
