Ternion Review

Apparently, ‘Ternion’ is an outdated word that refers to a group of 3, at least according to our Google search. It fits the bill in this release, as you get to meet a trio of superheroes consisting of a Fire Man, an Ice Lady, and a Blade Lady. The 5x4 grid is semi-transparent, so you get a good view of the somewhat dystopian looking city in the backdrop. You can also glimpse what looks like the superhero headquarters, as the skyscraper comes with their distinct ‘V’ logo.

Superheroes are nothing without their superpowers, and all 3 of them come with a special modifier that can benefit you at random times in the base game. The bonus round is all about collecting crystals to fill a meter, as this triggers increasingly more lucrative combinations of the superhero modifiers. The 11,111x potential is solid, as well as a lucky number for some, but Ternion cannot escape coming across as a tad too generic and charmless.

Ternion Slot Features

You need 3 to 5 matching symbols on a payline from the uttermost left to the right to win, and the premium symbols pay between 5 and 50 x your stake. The game logo Wild symbol steps in for pay symbols to help complete wins, and landing a pure wild win pays the same as the top-tier male fire superhero symbol.

Each of the 3 superheroes, of which there are 2 females and 1 male, come with their own dedicated modifier. This modifier can trigger at random times in the base game, and here is an overview of what you can expect:

  • Ice Shards - the grid is iced over which leaves 3 to 10 wilds in random positions.
  • Blade Flurry - removes all low-value symbols, and only premium symbols drop down to fill the gaps.
  • Pillars of Flame - turns up to 4 reels into full wild reels.

The Doomsday Bonus Round triggers when you land 3, 4, or 5 scatters on the same base game spin, and this gives you 8, 10, or 14 free spins, respectively. The Call For Heroes feature can trigger at random times, and it gives you 2 scatters on reels 1 and 2, which may help you trigger the bonus round. You win 4, 5, or 7 extra spins should you land 3, 4, or 5 scatters during the feature, respectively, and up to 38 free spins is the most you can get all in all.

The 3 hero modifiers are more powerful in the bonus round, meaning potentially more lucrative for you. When wilds land on top of each other, it increases the win multiplier by +1. You’ll collect Crystal symbols in a meter on the left, and you get hero superpower modifiers every time you collect 5. The more times you do this, the more hero superpowers are unleashed at the same time.

The 200 Spins Ternion Slot Experience

You get a brief taste of the base game, before the Call For Heroes feature helped trigger the bonus round for us at 0:28 into the 2:18-minute highlights video. You get to see several different modifiers triggered from the Hero Superpower Meter during the feature, and you can check it all out for yourself by hitting the play button below.

Review Summary

Play’n Go always delivers above average slot entertainment, but some of their releases just glides through without leaving a lasting impression one way or the other. Ternion is such a game, at least in our view. There is nothing overlay negative to point your finger at, but the superheroes are a bit too generic and charmless for a game like this. They are the main characters after all, and it can be hard to create such heroes from scratch with no brand recognition.

They keep you somewhat entertained in the base game via the 3 modifiers, however, and the Call For Heroes feature certainly helped us out as you can see in the video above. The wild reel modifier seems like your best bet for larger payouts, not least if the 4 leftmost reels turn wild. Get that combined with low-value symbol removal, and larger payouts are bound to come your way. The 11,111x potential is as palindromic as it is solid, but how can you have a proper superhero game without an evil super villain?


  • 3 random hero superpower modifiers
  • Call For Heroes award 2 scatters
  • FS w/ 5 crystals trigger hero modifiers
  • Win up to 11,111x your stake


  • Beware of adjustable RTP ranges
  • Max win hit rate is less than 1 in 100m
