Special Features

Hall of the Mountain King features a variety of Troll symbols that appear on the reels with the King of the Trolls (red background) being one of the most valuable symbols. Land 5 of these symbols and you will be leaving the mountain with a nice cash prize worth 40X your wager.

The Wild symbol in this game is represented by a gold shield with the letter ‘W’ displayed inside. It substitutes for all other symbols except the Scatter to help create winning combinations on the reel. This symbol along with the Troll King symbol is one of the highest paying symbols in the game as if you land 5 Wilds then you will receive a fine payout worth 40X your stake.

Whenever you land a win on the reels in this game then you will trigger the Multiplier Meter feature where each win is boosted by a multiplier value. This value is calculated based on how many Wilds are part of your win. For example, 4 or 5 Wilds will award a 4X or 5X multiplier and so on. The maximum Multiplier you can obtain here is 5X. In addition to this, Wild symbols can appear stacked on the reels which means that you can land even bigger Multiplier payouts.

The Scatter symbol in this slot is illustrated by an image of the Troll King’s hammer. Land 3 or more of these symbols on the same spin to activate the Free Spins Bonus Game. This exciting bonus round consists of 3 stages with each one having its own unique feature. The stages are as follows:

  • Stage 1 - Symbol Upgrade. When you form a win on the reels then the Troll King will smash 1 of the blocks in the upgrade meter which is found on the right-hand side. This will then remove the corresponding low-value symbol and replace it with stacks of the corresponding high-value symbol. So basically any low-value A, J, K, Q symbols will be removed and replaced by high-value Troll symbols instead. The Troll King can also smash the bottom of the block of the Multiplier Meter and when this happens the Multiplier Meter will be upgraded with multipliers increased to 15X instead of 5X.
  • Stage 2 - Whirling Wild Collection. You will gain access to this stage once you have broken the top block in Stage 1. In this stage when a Whirling Wild block is smashed then the Whirling Wilds inside the block are collected above the reels. A maximum of 6 Whirling Wilds can be collected and just like in Stage 1, multipliers can be increased to 15X. Smash the top block in this stage to proceed to the final stage.
  • Stage 3 - Whirling Wild Drop. You will be given 3 Free Spins in this stage with all collected Whirling Wilds that you have gathered in Stage 2 randomly dropping onto the reels and transforming into Wild symbols.

Theme, Graphics and Sound

This game is a visual masterpiece in terms of graphics and presentation. It is set in front of a forest with an ominous looking mountain in the background and white billowing clouds overhead all displayed in stunning detail. Symbols are beautifully crafted and consist of a bunch of different male and female Trolls along with classic A – 10 icons. Each troll has their own unique look and design to ensure they look completely different from each other. The animations are spectacular as symbols speed down the reels and are highlighted by a bright gold frame when part of a winning combination. They really come into their own in the Free Spins Bonus Game as the Troll King proceeds to smash and break blocks when he swings his huge hammer.

The music, of course, features the iconic classical piece “In the Hall of the Mountain King” by Edvard Grieg as the backing track to the game. It is a beautiful score and ties in perfectly with the Fantasy theme of the slot.
