Hall of the Mountain King (Quickspin): Review

Whether we were sending a pack of ferocious orcs crashing across the reels or watching the troll king heft his massive hammer to release the souls trapped in the whirling wilds, we kept thinking, “we may have no idea what’s happening, but it looks incredible!” Making it even stranger in the best way, everything plays out to the thunderous strains of one of the most recognizable orchestral melodies ever written. Trying to wrap your head around how the Quickspin dev team achieved this is like attempting to imagine the edge of space — your mind just starts to whirl. As you’ll discover, Hall of the Mountain King is a bold project and a true heavyweight slot. It’s not only loaded with features and slick animation, it also has real depth and a narrative thread. Much like Ivan and the Immortal King, there’s even a touch of culture while we fight to turn our last fading cents into a meaningful cashout.

Drawing inspiration partly from Norwegian composer Edvard Grieg’s renowned piece “In the Hall of the Mountain King“, with hints of Lord of the Rings and World of Warcraft mixed in, this creative take delivers a fantasy theme with a medieval edge. The 5×3, 20-payline layout might look straightforward at a glance, but a stack of features adds plenty of extra dimensions. Available on all devices with stakes from 20 cents to 100 Euros per spin, it includes progressive multipliers, stacked wilds, and a 3-level free spins bonus where symbols and multipliers get upgraded and whirling wilds help form winning combinations.

For many players, Mountain King might be “just another slot,” yet it’s obvious how much care and enthusiasm went into the storytelling and visual style. Speaking about the game’s creation, Quickspin lead artist Polina Mozgovaya said: “Mattias, the producer, told us his vision for the game and that it was going to be about trolls – exactly the kind of thing I love to draw! I got a general idea for the look pretty quickly, as it was inspired by various fantasy games and films.”

As expected from Quickspin, the visuals are top-tier — set in the vast northern lands, you’re accompanied by a crew of royal trolls. In the base game, the reels sit outdoors on a gorgeous green hill under bright blue skies. During the bonus, the mood shifts as you’re brought into the mountain king’s cave. On the reels you’ll find A to 10 card suit symbols alongside the 5 trolls, with the mountain king being the most rewarding, paying 40 times your stake for 5 of a kind. There’s also a wild that substitutes for all other symbols and is worth the same as the highest regular symbol.

Hall of the Mountain King (Quickspin): Features

In the base game, a meter sits to the left of the reels showing multiplier values. This Multiplier Meter feature triggers whenever one or more wilds land — seeing 1, 2, 3, 4 or 5 wilds on the screen awards a x1, x2, x3, x4 or x5 multiplier respectively. Since wilds can appear stacked, it’s possible to hit wins of up to 4000 times your stake from the base game alone.

At the heart of Hall of the Mountain King is the Free Spins bonus, which ramps up as you progress through 3 distinct levels, each bringing its own special mechanics. The feature starts when 3 hammer scatters land on the middle reels. Here’s what you can expect as the adventure begins:

Level 1

This stage focuses on gathering as many premium symbols as you can via the Symbol Upgrade feature. Either randomly, or after you land a winning combination, the troll smashes one of the blocks in the upgrade meter on the right side of the reels. The shown low-value symbol is then removed and replaced by stacks of the matching high-value symbol. On top of that, the troll may also break the bottom block of the multiplier meter, boosting all multiplier values — with multipliers able to reach a maximum of x15. You advance to the next stage once the top block has been destroyed.

Level 2

In stage two, the goal shifts to collecting Whirling Wilds. When the troll breaks a Whirling Wild block, the wilds inside are gathered and kept hovering above the reels until they’re needed later — you can collect up to 6 wilds altogether. The multiplier meter remains active here too, continuing to upgrade as long as the troll keeps smashing multiplier blocks. Just like level 1, you move forward when the top block has been destroyed.

Level 3

The last stage marks the peak of the Mountain King storyline. With upgraded symbols and whirling wilds at your disposal, all the collected enhancements combine to powerful effect. You’ll receive 3 spins with the Whirling Wild Drop feature to help build winning combinations — on each of the 3 spins, a random number of Whirling Wilds drop onto the reels.

Hall of the Mountain King (Quickspin): Verdict

With its many moving parts, surprises, and layered mechanics, this is a slot that’s easy to appreciate — especially given the well-judged balance between fun gameplay, volatility, and huge potential. That said, Mountain King can be bewildering at first, and even after several bonus rounds, we still didn’t feel we had a complete grasp of everything happening. Because of that, some players may find it a little too much, particularly old-school fans who swear by the idea that less is more. Still, with 7326 times your stake on offer, it has a strong chance of appealing to a wide range of players.

Hall of the Mountain King is a big-swing release, and arguably one of Quickspin’s largest projects to date. It’s not only an artistic production with a memorable story supported by a powerful soundtrack and striking visuals, it also delivers an unusual play experience where each bonus round feels distinct from the last. The main unknown is whether Mountain King can keep its momentum after launch, but so far the signs look encouraging.
