Rise of the Mountain King RTP and Volatility

7.7 
The slot comes with an RTP of 96.31% and high volatility.
The game`s high volatility means that you’re likely to get generous payouts during the gameplay, but they won’t occur as frequently as in low and medium volatile slots. The average return-to-player percentage of 96.31% indicates that a player theoretically is guaranteed €96.31 for each €100 spent on the game.

Theme

8.9 

The Rise of the Mountain King slot exploits Nordic mythology. Nevertheless, it is a modern-looking slot, unlike most NextGen games that have more old-school looks. The cartoonish graphics are of premium quality and the use of Grieg`s famous orchestral piece in the soundtrack is impressive.

The 10 normal symbols consist of 4 low-paying and 6 high-paying icons. The Mountain King himself serves as the game`s Wild symbol that has the ability to expand, and the Gemstone is a Scatter.
