Play’n GO has a diverse slot catalog that has covered a wide range of themes and stories over the years. The developer has decided to take a sci-fi angle for the Ternion slot, a game that certainly cannot be accused of lacking creativity. The action takes place in front of a burning metropolis, though how the world ended up there is unclear. What we can straighten out, though, is everything you need to know about Ternion’s gameplay, winning capabilities, and bonuses, all of which we will explore in this Ternion slot review.


The Ternion slot throws players right into the middle of a Doomsday event. The game has a striking design that could have been taken straight from a video game. You will join a group of freedom fighters as they attempt to overcome the malevolent presence that has overthrown the planet. Just what that presence is remains to be seen, with the game not being too straightforward in its story. This doesn’t make a difference, though, as the game’s visuals more than make up for lack of a clear narrative.
Ternion’s creative design has no problem making a move onto mobile devices. Play’n GO has developed the slot with HTML5 technology, ensuring it runs smoothly across multiple devices and screen sizes. Most top rated online casinos will support mobile play, so you should have no problem finding somewhere to take the Ternion mobile slot for a spin.
Ternion might have a creative design, but the base game keeps things more grounded. The slot uses five reels and four rows, with 40 active paylines on each spin. Like other Play’n GO slots, the stake is adjusted on a sliding scale beneath the grid. The minimum bet in the game is $0.40, and the maximum is $100, which is a fairly standard range.
You will find the Autospin and Turbo options next to the Spin button, allowing you to speed the action up or sit back and watch it unfold while you put your feet up.
There are three main characters in the Ternion slot game, each with its own modifier. These can be triggered on any random spin. Ice Shards creates between three and ten wilds on the reels. Blade Flurry removes all low-paying symbols and adds higher-paying ones into their positions, and Pillars of Flame turns up to three reels fully wild. During the free spins round, each of these bonuses is increased. Ice Shards adds up to 16 wilds, Blade Flurry removes the Crystal symbol, and Pillars of Flame turns up to four reels wild.
The main bonus in the game is the Doomsday Free Spins. They become active when you land three or more scatter symbols. Three, four, or five scatters reward eight, 10, or 14 spins, respectively. The Call for Heroes feature can help you trigger free spins. This adds up to two scatters to the reels for a base game spin.
During the Doomsday Free Spins, Crystal symbols are collected in a meter. A random character modifier is triggered if you fill the charger once or twice. Two modifiers are launched on the third and fourth, and on the fifth, all modifiers become active.
Ternion has a strong math model, offering up some decent wins. The game has been given a 9/10 volatility rating by Play’n GO, so while big wins are possible, you may have to wait a while for them. The RTP is 96.20%, which is higher than average. Like other Play’n GO slots, multiple versions are available, so be sure to check the paytable. The maximum win in the game is 5,000x your stake.
The Ternion slot initially stands out for its unique design and style. Once it has grabbed your attention, it does an excellent job keeping it, thanks to a selection of bonus features and some involving gameplay that keeps each spin interesting. The possibility of triggering a modifier on any spin keeps the game exciting, and the Doomsday Spins is a fun bonus. The game brings back memories of Play’n GO’s Moon Princess games, which is never a bad thing. Overall, this is a solid offering from Play’n GO. Head up to your favorite online casino, grab a free spin offer, and enjoy the game.
