Ternion - Slot Review

The Ternion slot is played in an apocalyptic atmosphere, with the background revealing a megalopolis under attack from powerful creatures from another world. Skyscrapers are engulfed in flames, releasing thick smoke into the sky, which bodes ill for our team of heroes. Marvelosa, The Incredible Wonder and Windstorm make up the trio of powerful heroes you’ll find on the reels, adding Wilds, Stacked Wilds and deleting unrewarding symbols. Free spins and a progressive feature offer the chance to win big prizes while liberating the city from this menace.


The Blade Furry feature leaves only premium symbols on the reels.

Designed on a 5×4-reel, 40-payline grid, the Ternion slot plans to deliver a highly volatile gaming experience with an RTP of 96.20% and a potential payout of up to 5000x the stake. In an attempt to avoid the apocalypse, a bet of between $0.40 and $100 per spin is required to start the game.

All symbols can pay from left to right, starting from the leftmost reel, and you need to line up 3, 4 or 5 identical symbols on adjacent reels to win. The A, K, Q, J and 10 symbols are the low-paying elements, paying between 4x and 48x the stake per line. Alternatively, the three heroes and the Doomsday symbol can pay higher rewards of between 20x and 2200x the bet per line. The Wild can also replace any symbol except the Scatter.

Find 3, 4 or 5 Scatter Bonus symbols to receive 8, 10 or 12 Free Spins. It’s possible to win an additional 4, 5 or 6 during the bonus to earn up to 35 Free Spins.

During the bonus, crystal symbols will be collected and stored to fill the charge meter. Every five crystals collected, the charger fills up, and by filling it up to 2x, 4x or 5x, you’ll trigger one, two or three Super Hero powers. What’s more, the super powers are upgraded during the bonus, so the Super Ice Shards generates from 3 to 16 Wilds, the Super Blade Flurry also removes crystal symbols and the Super Pillars of Flame generates from 1 to 4 Wild Reels.
