Hall of the Mountain King is powered by Quickspin with 5 reels and 20 paylines. With a medieval/fantasy theme, you can play from 20p to £100 a spin across all devices. Inspired by Edvard Grieg’s famous classical piece, it comes with stacked wilds, multipliers and a free spins feature where symbols are upgraded, multipliers are upgraded and whirling wilds are added to the reels.

Visually, Hall of the Mountain King is rather nice – set in the vast lands of the north inside a mountain, you will come across the king of trolls. With a peaceful setting, symbols on the reels include A, K, Q, J and 10 royals as well as 4 different trolls. The most lucrative troll is worth 2, 7.5 or 40 times your stake for 3, 4 or 5 on a payline. There’s also a wild that performs the usual substituting duties and pays like the highest value troll.

When you get a winning combination, the Multiplier Meter feature kicks in – each win is subject by the indicated multiplier in the Multiplier Meter to the left of the reel set. The multiplier value is determined by how many wilds are part of your win – 1, 2, 3, 4 or 5 wilds will give you a 1x, 2x, 3x, 4x or 5x multiplier respectively. Furthermore, wilds are stacked meaning bigger multipliers can be applied to your winnings.

Hall of the Mountain King comes with a Free Spins Bonus feature – this is entered when you get 3 or more Troll King hammer scatters on the 3 middle reels. The feature consists of 3 stages – each offering you its own unique feature.

Stage 1 gives you the Symbol Upgrade feature – when you get a winning combination, the Troll King breaks 1 of the blocks in the upgrade meter on the right. This seems its corresponding low value symbol removed from the reels and replaced with stacks of the corresponding high value symbol. Basically, royal symbols are replaced by trolls symbols for bigger payouts. The Troll King can also break the bottom of the block of the multiplier meter which upgrades all multipliers – these multipliers can reach 15x.

Stage 2 gives you the Whirling Wild Collection feature – this is entered once the top block has been smashed in stage 1. When a Whirling Wild block is smashed, the Whirling Wilds inside the block are collected above the reels. Up to 6 Whirling Wilds can be collected in total. Like in stage 1, multipliers can be upgraded up to 15x.

Stage 3 sees the Whirling Wild Drop feature comes into play. This is accessed once the top block has been smashed in stage 2. Then all collected Whirling Wilds are randomly dropped onto the reels for 3 free spins.

Hall of the Mountain King is visually excellent – as are all slots from Quickspin. I like the Multiplier Meter feature which can give you big wins in the base game and the Free Spins Bonus feature. It’s all about the 3 free spins in Stage 3 as the wilds can really boost your win potential – especially if you have a 15x multiplier.

High variance, you can win an impressive 7,326 times your stake on each spin/free spin involving the 15x multiplier. I recommend you take a look at other Quickspin slots which, on the whole, are superb – the tranquil Divine Dreams and the gladiator inspired Tiger’s Glory are my 2 picks.
