Hall of the Mountain King Slot Review

Released May 2019

The Hall of the Mountain King slots game can be found at casinos offering Quickspin software. Quickspin are one of the newer slots game developers on the market but their products are polished and professional in feel and operation. As a standard Quickspin do publish the RTP/House Edge information for their slots games within their game help file. For a provider that are not currently licensed within the UK market and therefore are under no obligation to publish these figures this is a significantly progressive move. The House Edge of Hall of the Mountain King is 3.71%.

Hall of the Mountain King is a 5 reel game that is 3 symbols high. There are 20 paylines available, playing from left to right.

Special Symbols

Wild – The Wild Symbol substitutes for all symbols except Bonus Scatter symbol. Each Wild symbol activates one multiplier, starting from bottom, up to a maximum of 5 times the bet.

Bonus Scatter Symbol – The Bonus Scatter symbol is the “Hammer”. 3 or more of them anywhere on the reels will trigger the game’s Free Spin feature.

Valuable Symbol – The highest paying symbol in the game is the “Mountain King” symbol, which will pay out 2 times the bet if you land 3 as part of a winning payline; 7.5times the bet if you land 4 as part of a winning payline; and 40 times the bet if you land 5 as part of a winning payline.

Bonus Features

Bonus Meter – The Bonus meter is only available during the Free Spins feature. During the feature it will highlight low paying symbols and the high paying symbols that they can turn into. Winning paylines will result in Upgrade Blocks being smashed. Smashing all the blocks will trigger Stage 2.

Free Spins - 3 Bonus Scatter Symbols in the same spin trigger the Free Spins Bonus. The Free Spins feature consists of 3 different stages:

Stage 1 – During this stage there are Symbol Upgrade Blocks that can be smashed. If this does happen it will take a low paying symbol and replace all of them with a high paying symbol. The stage ends when the top Symbol Upgrade block has been smashed.

Stage 2 - When a Whirling Wild block is smashed, the Whirling Wilds inside the block will be collected above the reels. A maximum of 6 Whirling Wilds can be collected. The stage ends when the top Whirling Wild block has been smashed.

Stage 3 - During stage 3, all collected Whirling Wilds will drop into random positions on the reels and turn into Wild Symbols. The stage ends after 3 spins. Ending stage 3 also ends the Free Spins Bonus.


Hall of the Mountain King takes you on a trip deep into the heart of the kingdom of Trolls. This has to be one of Quickspin’s best releases of the year so far. The game looks fantastic and despite only really having the one feature is immersive and seriously good fun to play. That one feature is the Free Spins and it has to be about as complex as any Free Spins feature that I’ve seen. You get meters, levels and additional features within them, making this a game that truly makes the most of out of what appears to be very little. The house edge is reasonable, meaning there is little here we wouldn’t recommend.
