Rise of the Mountain King Slot RTP, Details and Wager Limits

Reels/Paylines: 5 reels + 30 paylines

Stakes Range: 30p to £15 per spin

RTP: 96.31%

Max Win: 50,000 x stake per spin

The Rise of the Mountain King slot game has 5 reels, 3 rows and 30 paylines. Winning combinations are formed in the traditional way by landing 3 or more matching symbols across any of the paylines. The only exception is the scatter where you need just 2 on a payline.

You can play from 30p up to £15 per spin, and there’s an Autoplay option where you can choose between 10 and 100 continuous spins. In the settings, you can pick the quality of the graphics and also place the spin button in the middle right, bottom right, middle left and bottom left positions.

The Rise of the Mountain King RTP is 96.31%, which is higher than average and quite generous. But with it being a very high variance slot, big wins are few and far between.

The maximum win per base game spin is 500 x your stake. However, if you add in the potential 100x wild multiplier during the bonus feature, you could win up to 50,000 x your stake.

Theme – Audio and Design Features – Epic Norse adventure

Theme: Norse Myhtology

High Value Symbol: Mountain King Wild

Compatibility: Mobile, Tablet, Desktop


The Rise of the Mountain King slot game has a Norse mythology theme as you head on an epic adventure to the Norwegian mountains. With a grand feel, you are taken to the skies and you’ll see a dark and mysterious fortress in the backdrop. The soundtrack is very dramatic which adds to the intensity and experience.

Symbols include Norse style A, K, Q, J, 10 and 9 royals as well as higher value symbols such as axes, shields, trolls and princesses. The most lucrative symbol is the Mountain King wild, which substitutes for all symbols except the scatter. Landing 3, 4 or 5 in combination will reward you with 1.33, 6.33 or 16.66 x your total stake.

Overall, the graphics, animations and audio are terrific and eye-catching. This is really a top slot in this regard.

Rise of the Mountain King Mobile


You can play Rise of the Mountain King on all devices as it’s been made using HTML5 technology. This means it’s playable on PCs, laptops, smartphones and tablets. The visuals look great on smaller iOS and Android screens.

Rise of the Mountain King Bonus Features

Rise of the Mountain King has 2 main bonus features. Firstly there are respins where new wilds give you more respins. Secondly, the Rise of the Multiplier feature can reward you with unlimited free spins. Collecting scatters during the bonus round will increase the wild multiplier up to 100x.

King’s Re-Spin feature


The King’s Re-Spin feature is played when 3 or more Mountain King wild symbols appear anywhere on the reels. With an initial payout awarded, you’ll get a free respin. Any scatters appearing on the triggering spin transform into wild symbols before the respin takes place.

Once they begin, wild overlay symbols spin across all symbol positions. If another wild symbol lands, you’ll get another respin. The respins carry on until no more new wilds appear. If you manage to fill the reels with wild symbols, you’ll win 500 x your stake.

Rise of the Multiplier feature


The scatter symbol is the gemstone, with 2, 3, 4 or 5 giving you 2, 5, 20 or 250 x your stake. Landing 3, 4 or 5 will also activate the Rise of the Multiplier feature with 8, 9 or 10 free spins respectively.

A Collect Meter then appears above the reels with the triggering scatters added. Every scatter symbol that appears during the feature will increase the scatter collect count by 1 and reward you with 1 additional free spin.

When you get a winning combination that includes a wild symbol, a multiplier value is applied to your win. Beginning at 5x, collecting scatters will take you to more levels where the wild multiplier increases. You can see the max win per free spin with the various multipliers on offer:

Level Trigger Wild Multiplier Max Win per Free Spin
1 Upon entry 5x 2,500 x stake
2 Collect 6 scatters 10x 5,000 x stake
3 Collect 9 scatters 15x 7,500 x stake
4 Collect 12 scatters 25x 12,500 x stake
5 Collect 15 scatters 50x 25,000 x stake
6 Collect 18 scatters 100x 50,000 x stake

Furthermore, each scatter will add additional free spins each time, which means there are unlimited free spins available in theory. The King’s Re-Spin feature can also be triggered with a screen full of wild symbols and big multipliers.

Buy Pass feature

Rise of the Mountain King comes with a Buy Pass feature which can be found in other NextGen Gaming slots. You can buy your way into the Rise of the Multiplier feature for a consideration of 100 x stake. You can also gamble for a chance to activate the Buy Pass feature. However, this option isn’t available in the UK.
