Troll Hunters is a high-volatility slot from Quickspin released in 2015, set in a Norse folklore world of stone-carved trolls, woodland warriors, and Viking-era adventurers. The game runs on a 5×3 grid with 243 ways to win — a format that was gaining mainstream adoption at the time and allowed wins from any matching combination of adjacent symbols rather than restricting results to fixed payline paths. The visual design uses a hand-painted illustration style, with detailed character artwork for the four hero symbols who serve as the highest-paying icons on the reels.
Quickspin built Troll Hunters around a free spins round that improves progressively as the bonus continues. Three or more Viking warrior scatter symbols trigger the free spins, and once inside the bonus a stacked wild reel mechanic activates. A designated reel column accumulates additional wild symbols each time a wild lands elsewhere on the grid during the bonus — the stack grows taller with each wild, eventually filling the entire reel with wild symbols for subsequent spins. This creates a bonus round where later spins are statistically more valuable than earlier ones, rewarding longer bonus sequences with disproportionately improved win potential.
A Wild Storm feature can activate randomly during the base game between paid spins, adding multiple wild symbols to the reels for a single boosted spin. This provides unpredictable win opportunities outside the bonus round and maintains engagement during non-triggering base game sequences. The 96.51% RTP is competitive for a high-variance title from 2015, and the 243-ways format provides broader base-game win coverage than narrower payline structures would allow at the same bet level.
Troll Hunters delivers solid high-volatility gameplay with a free spins round that rewards patience. The escalating stacked wild mechanic means longer bonuses yield disproportionately better results. At 243 ways with a 96.51% RTP, it is a well-balanced representative of Quickspin's slot development capabilities.
