Hall of the Mountain King Slot Review

Hall of the Mountain King - Slot Overview

Hall of the Mountain King from Quickspin grabbed me straight away with the Grieg soundtrack and the troll kingdom setup. The slot runs on a 5x3 grid with 20 fixed paylines and stakes from 0.20 to 100 per spin, so it fits both testing and serious sessions. The base game looks calm on a green hillside, but I always feel the tension of that mountain and the king waiting inside.

Once the bonus kicks in, the scene shifts into the king's cavern and the whole slot suddenly feels more brutal. Quickspin's animation work sells the hammer hits, whirling wilds and stacked trolls really well on both desktop and mobile. Under the pretty surface, though, this is a high volatility slot with layered mechanics and a max win of 7,326x stake, so I treat it as a serious balance swing game.

RTP and Volatility in Hall of the Mountain King

On the stats side, Hall of the Mountain King has an RTP of 96.29%, which sits nicely above many branded slots I play. It feels very high variance in practice, with long dry spells broken by sudden hits when the Multiplier Metre cooperates. In the base game wins can reach around 4,000x stake with stacked wilds and a 5x multiplier, while the bonus pushes potential to 7,326x.

How to Play Hall of the Mountain King Online

When I load Hall of the Mountain King, I first set a bet level that suits the bankroll, anywhere from 0.20 to 100 per spin with all 20 paylines active. Wins land when three or more matching symbols hit a line from the left, helped by wilds. Autoplay handles up to long sets of spins, and the quick play option keeps the rhythm sharp when I am grinding for the feature.

My personal aim in the base game is simple enough. I want stacked wilds landing together because each wild steps the Multiplier Metre up from 1x to 5x and the top multiplier applies to the whole win. At the same time I watch for Hammer bonus scatters on reels two, three and four, because three of those symbols are the ticket into the multi-stage free spins feature.

Symbols and Paytable in Hall of the Mountain King

In Hall of the Mountain King the paytable splits cleanly between troll premiums and card suit lows. The Mountain King himself pays 40x stake for five on a line, matched by the wild symbol, while the Troll Queen pays 20x. Below that sit the female troll at 15x, the male troll at 10x, and the ork at 7.5x for a full line, so hitting stacked premiums feels very satisfying.

The low-paying symbols are the familiar tens through aces, paying between 2.5x and 6.25x stake for five. They carry the bulk of the small base game hits for me, keeping the balance from collapsing too fast. The Hammer scatter does not pay by itself but is vital for bonuses, while Whirling Wilds arrive as collected wild symbols in free spins, dropping onto random positions to finish off stronger troll combinations.

Free Spins and Bonus Features in Hall of the Mountain King

In the base game the Multiplier Metre on the left takes centre stage for me. Any win that involves one or more wilds gets multiplied by the highest active value, from 1x up to 5x, so even a medium line can spike nicely. The real action, though, lies in the free spins feature, which you trigger by landing three Hammer scatters on reels two, three and four. Those scatters open a three-level bonus.

On level one of free spins, every qualifying win prompts the Troll King to smash a stone on the Upgrade Metre to the right of the reels. Each broken stone removes a low-paying symbol and replaces it with stacks of a higher paying troll symbol. Sometimes he also hits the Multiplier Metre, raising the values so the maximum multiplier in the feature climbs to 15x, which can turn upgraded symbol hits into serious payouts.

Level two focuses on Whirling Wild collection. When the king breaks a Whirling Wild block, the stored wilds move above the reels and wait there, up to a cap of six. Level three is the payoff. You get three free spins where those collected Whirling Wilds drop randomly onto the grid on every spin. With upgraded troll symbols and a 15x multiplier in play, these spins can either miss badly or explode magnificently.

Overall Review of Hall of the Mountain King Slot

Overall, Hall of the Mountain King has become one of my go-to troll slots when I fancy something with real depth and danger. The combination of Grieg's build-up, the three-stage free spins and the constantly relevant Multiplier Metre keeps me engaged even through lean stretches. It is not a simple starter slot, but when the features line up it can produce sessions I talk about for weeks.
