Whirling wilds and increasing multipliers

Quickspin is back with a brand new slot, and we will have a look at its features and bonuses in this review. The game has 5 reels, 3 reels and 20 paylines, and you can bet between £0.20 and £100 per spin. Hall of the Mountain King is originally a musical piece by the famous composer Edvard Grieg, and it’s interesting to see it being turned into a Quickspin slot. The slot includes parts of the original music, giving the game its mythical atmosphere.

Hall of the Mountain King has ten symbols: the low paying symbols 10, J, Q, K and A, and four high paying troll symbols. The Mountain King symbol is worth the most, and five of a kind of this symbol pays a win of 40x. However, the game also has wilds that massively increase the wins in both the base game and in the bonus. Every wild you get increases the multiplier of the win by one, up to a maximum of 5x. One wild on the screen is a 1x multiplier, two wilds anywhere is a 2x multiplier, and so on. The wilds can come stacked too, giving you more lines of wins and a higher multiplier. If you combine a few wilds with the top symbol, you could be looking at a 200x win in the base game.

The low and medium symbols are not worth a lot in Hall of the Mountain King, so it’s nice that the whirling wilds frequently show up to boost your winnings. Keep an eye on the multiplier meter on the left side of the reels, as you will see it increasing by every wild that lands anywhere on the reels. The maximum multiplier in the base game is 5x, but it can increase even more in the bonus. When three hammer symbols land in the middle three reels, the free spins bonus is activated, and this is where the rich treasures of Hall of the Mountain King await.

Free spins with upgraded symbols and extra wilds

Quickspin has come up with a very unique bonus game for Hall of the Mountain King, as it has three different stages. The free spins mode is triggered when you get three hammers on the three middle reels. You will immediately begin the first stage, where the goal is to upgrade the lower symbols and increase your multiplier. In the second stage, you collect wilds that drop down on the reels during stage three.

  • Stage 1: when you hit a win, the corresponding low paying symbol that is highlighted on the right side of the reels is smashed and replaced with a high paying symbol. The Mountain King can also smash the multiplier blocks to increase your bonus wins multiplier. The second stage of the bonus takes place once the top block has been smashed into pieces.
  • Stage 2: the second part of the bonus game is the whirling wild stage. In this stage, the goal is to collect wilds by hitting wins on the reels. You can earn up to six whirling wilds by getting multiple wins, and the last block gives you two wilds instead of just one. Progression to the third and final stage begins once you have smashed the top block.
  • Stage 3: the third part of the bonus game is the most exciting one. During the third stage, all the whirling wilds you collected during the second stage will randomly drop down on the reels. You might have many upgraded symbols, a big multiplier and several wilds at this point, giving you a chance of getting huge wins. The stage and the free spins bonus ends after three spins, when all the wilds have dropped down.

Graphics and sound

The graphics, music and sounds in Hall of the Mountain King are incredible. The game takes place in front of a beautiful mountain surrounded by grassy fields, and you can hear parts of Edvard Grieg’s Hall of the Mountain King piece play in the background. If you have ever heard this epic classic song, you will instantly recognise it when you start playing the game. The music and the scene changes when the bonus game is triggered, as you will be invited into the hall where the Mountain King is sitting on his royal throne. Quickspin has once again created a very pretty game that looks fantastic on both desktop and mobile.


Hall of the Mountain King is an excellent slot by Quickspin, and the music and design are like from a fairytale. The game has a good RTP of 96.29%, and it goes quite high on the volatility scale since the maximum win is over 7,000x in the bonus game. You can also pick up nice wins in the base game, thanks to the whirling wilds that drop down and multiply your winnings. The more wilds you get, the bigger the multiplier goes – and you could multiply your wins up to 5x in the base game.

The free spins bonus game is the best part of Hall of the Mountain King. The bonus has three stages, and the goal is to upgrade the low paying symbols and collect wilds while also building the multiplier. In the last stage of the bonus, all the collected wilds will randomly drop down on the reels. If you like one of the most famous musical pieces by Edvard Grieg, or if you just want to play a fun slot, you can’t miss out on Hall of the Mountain King!
