Deep in the highlands where mythical creatures reside, Hall of the Mountain King brings the story of trolls back to life using only 20 active paying lines. Equipped with 5 reels and a plethora of Spins and Multipliers, Quickspin shows us that even ogres can be friendly and pleasant. Or at least hospitable.

RTP & Volatility

High variance and 96.29% RTP (Return to Player) rate ensure potentially astronomical payoffs, albeit rare. Entrance into the hall will not be easily gained, but the periodic encounters with Multipliers will definitely serve as welcome encouragement while you wait. No matter which device you prefer, Hall of the Mountain King is available everywhere.

With a price, of course – bets go from €0.20 to €100 per round. Deeply satisfying visuals and a well-balanced reward system make this video slot a great choice for all types of enthusiasts.

Hall of the Mountain King Bonus Features

7.7 

The main objective is to get to the King’s Hall where Free Spins are waiting to be used. By finding three Hammers on the reels, you will automatically unlock the Free Spins Mode and go straight to meet the leader of ogres. He’ll offer you three stages of free play, each unlocked by successful completion of the one before that.

In the first stage, you’ll come across the Symbol Upgrade feature, wherewith each hit combo, the King smashes one of the rocks, thus substituting all instances of one certain low-value tile with the equivalent high-value icon. Once he destroys the final one, the first part is finished. The following phase introduces Whirling Wild Collections.

Again, he needs to crush those big chunks of stone, and each time he does that – Whirling Wilds are released from the shattered stone and congregated above the reel set. As soon as the final chunk is destroyed, the Wilds storm the reels, thus setting in motion the ultimate stage.

During both the standard and Free game you amass Multipliers. Your progress is clearly visible on the left side where the Multiplier meter is positioned. The max number of these is 15, meaning that you can augment your win 15 times.
