Were Check Out the Unique 3 Stage Bonus Round and Win Potential in Quickspin’s Latest Slot Hall of the Mountain King!

Leo Vegas Casino

Quickspin’s latest slot release Hall of the Mountain King looks to shake things up a little, with a whole host of new ideas which include a 3-stage free spins bonus round along with a win potential of up to 7000x stake!

The official release date for this slot is the 14th May 2019, but you can already check out this early at LeoVegas Casino as they currently have an exclusive on this title.

Hall of the Mountain King is a regular 5×3 reel machine with 20 fixed paylines but comes packed with a variety of special features which include stacked wilds, free spins, multiplier upgrades, symbol replacement, whirling wilds all packed into the base game and the unique bonus round. Inspiration was taken from the famous classical music piece “In the Hall of the Mountain King” by Edvard Grieg.

Whilst the base game doesn’t boast too many special features the wild multipliers that can come into play along with the higher paying picture symbols do ensure that some nice base hits are possible (see screenshots below), but this slot in particular really starts to shine when you manage to trigger the free spins bonus round.

The 3 stage bonus round can be quite confusing at first as it plays out, and it is probably worth having a quick read through the paytable before playing, just to get a rough idea of what is going on, and so you can tell if it’s looking a good bonus round or not.

Whilst the win potential is obviously there thanks to the rising multipliers and symbol upgrades during the bonus round, we did have a few reservations about this slot, the bonus round was a total breath of fresh air in terms of design and offering something new! but the overall volatility might just put a few players off before seeing this slots full potential.

Special Features

Multiplier Meter

The Multiplier meter situated on the left of the reels will rise in value depending on how many wilds are present on the reels when you land a win, this alters slightly in the bonus round with the Troll King smashing blocks to upgrade the base multiplier value too.

Stacked Wilds

There are Stacked wilds present on the reels, which really help to really increase the Multiplier values and hence the overall wins.

Free Spins Bonus

Triggered by landing 3 Scatter Symbols you are then transported to the unique three-stage bonus round.

Any wins that you land during the bonus round will make the Troll King break one of the blocks, and possibly a multiplier block too, if he breaks the top block in any of the stages then you will move onto the next stage.

Basically the more blocks you can break before entering the next stage the better overall win potential of the bonus round.

  • Stage 1: Remove low-value symbols and replace them with high-value symbols.
  • Stage 2: Collect whirling wilds.
  • Stage 3: All whirling wilds come into play in 3 spins.

Overall Opinions

Hall of the Mountain King Slot is certainly an interesting slot release from Quickspin, we have to admit that for the first few bonus rounds we really didn’t understand fully what was going on, as the number of free spins that can occur along with the total number of upgrades you earn can vary massively along with working out what was triggering the movement to the next stage.

Once you get a grasp on how these mechanics work you can start to sense how good or bad the bonus round is going to be, which really does add lots of excitement when the multiplier has risen to over 10x, you have lots of symbol upgrades and lots of added wilds for the final spins.

In our playtests, we had very varied bonus round results ranging from as lows as 3x to well over 300x stake with lots more potential given the maximum 7000x stake wins that are possible. The biggest negatives from the bonus round are the reliance on getting lots of upgrades, multipliers and added wilds in order to stand a chance of hitting the big wins, that niggling feeling that bonus round end result may have already been decided when very few upgrades were awarded.

Overall though hats off to Quickspin for coming up with such an unusual twist to a free spins bonus round, when we have to resort to checking the paytable to understand the mechanics we know we have encountered something fresh and new!
