How the Game Plays

Reign of the Mountain King returns to the dark, cavernous halls of the troll monarch, serving as the volatile successor to the original 2020 release. The game utilizes a 5x3 grid with 10 fixed paylines, where wins are achieved by matching Nordic-themed symbols like axes, shields, and trolls from left to right. The experience is defined by its dramatic orchestral score, heavily featuring a metal-inspired rendition of Grieg's "In the Hall of the Mountain King."

King's Respin Explained

Unlike many modern slots, this Light & Wonder title does not feature a traditional free spins bonus. Instead, the gameplay revolves around the King's Respin feature. This is triggered by landing three or more King Wilds anywhere on the reels. During the respins, all triggering wilds lock into position while the remaining reels spin again. If any additional wilds land, they also become sticky, and the process repeats until no new wilds appear or the grid is filled.

Multiplier Wilds and Gem Trail

The game's primary win potential comes from its multiplier wild system. In the base game, King Wilds can carry multipliers that combine to significantly boost payouts, theoretically reaching as high as 512x. During the respin feature, a Gem Trail is activated. Players collect gem symbols to progress along the trail, which upgrades the multipliers attached to the sticky wild symbols. These multipliers can reach up to 8x per wild, leading to the game's top prize of 10,000x the stake.
