Reign of the Mountain King Features

There are fewer features in this game compared to the original - but that's not to say that they are bad. The wilds, which are the Mountain King, substitute all symbols and landing 3 of this triggers the Mountain King respin.

Each wild has a x1 multiplier that locks in position and each time a wild appears, the symbols will lock in and display a multiplier as shown on the gem trail. This bonus ends when there are no new wilds or gem symbols.

When a gem lands, it will move to the trail displayed above the reels with multiplier values that can go up to x8. Once three gems are collected, the trail starts again leading to additional multipliers.

If a wild lands in the base game and there is only one wild in view whilst being part of a 4 or 5-of-a-kind win, then the wild can be given a multiplier from x5 to x512.

Reign of the Mountain King Review

It's hard to top Rise of the Mountain King as the game was such an iconic slot that just resonated with every player that tried it. However, SG Digital is certainly going to try with Reign of the Mountain King.

Playing on 5-reels with 10 paylines, this game cuts out the free spins round from the original and instead enhances the respin mechanic with even bigger multipliers. See if the Reign of the Mountain King is worthy enough to live up to the masterpiece that was the original.


It's clear that the developers have gone for a more realistic style of design by taking inspiration from World of Warcraft in the designs. By realistic, we mean in the design of the humans and troll-hybrids looking like cosplayers rather than creatures.

The beauty of the original slot was the charming quality of the designs looking quite soft, but there are harsh lines throughout this game that make it seem quite generic. That's not to say that it looks bad, but it's nothing compared to the original.

As previously mentioned, all the symbols return from the previous game but with different designs that lean more towards typical slot characters. The music from Edvard Grieg's score is still in this slot but is not as consistent and randomly cut out throughout which was frustrating.


The gameplay of the original slot was not anything revolutionary but it was enough to deliver thrills. Sadly, this slot cuts out the free spins round to enhance the respin mechanic with bigger multipliers. However, it only feels like this is the only feature throughout making it quite tedious if you fail to trigger it.

All the menus can be found on the right side of the screen with the spin button and bet level button. Players struggling to comprehend can find a paytable button on the left side of the screen.

Win Potential

Whilst the win potential for this slot is definitely not poor, it's a little disappointing compared to the previous game. The RTP is lower but it's still on the average level of 96%.

Of course, the high volatility returns but there is a lower win of up to 10,000x stake. This is not bad and will delight players, but it's strange that it's gone down from 50,000x stake to 10,000x in the sequel.

Our Verdict

If this game came out on its own, then it would've been a hit. Sadly, it follows the masterpiece that is Rise of the Mountain King which leads players to make natural comparisons.

The lack of the free spins round and the update in visuals is not what we wanted. The original game feels charming, whilst this game feels generic. That's not to say it's a bad game, but the previous title is just so much better.
