Ternion

Ternion by Play'n GO is a video slot with 5 reels and 4 rows, featuring 20 fixed paylines. In the futuristic Victory City, three heroes – Marvelosa, The Incredible Wonder, and Windstorm – battle threats like monsters and an apocalypse machine. During the base game, random "Hero Modifiers" can occur: Ice Shards (adds 3–10 Wilds in random positions), Blade Flurry (removes the low-paying symbols), and Pillars of Flame (transforms 1-4 reels into stacked Wilds). Additionally, there is the "Call for Heroes" feature, which is activated randomly to place two Scatter symbols on the first two reels, increasing the chance of triggering the bonus game. The Free Spins round begins when three or more Scatter symbols land, awarding you 8, 10, or 14 free spins, depending on the number of Scatters. In the Free Spins, the "Hero Superpowers" are utilized more effectively, and Wilds landing on other Wilds can increase the win multiplier. During this round, you collect crystal symbols to fill a meter (Crystals Charger); with multiple fills, you can activate several superpowers simultaneously. Free Spins can be retriggered – additional free spins (4-6) are granted if more Scatters land during the Free Spins, up to a maximum of 35 spins. The game includes Wild and Scatter symbols, but there is no separate bonus buy option. The visual presentation and sound support the superhero theme with vibrant graphics and dramatic effects.
