Rise of the Mountain King Online Slot Machine – Free Play & Review

The fantasy genre is the one being approached in Rise of the Mountain King. This game features trolls as main characters, precious stones, beautiful young women and other creatures that are lifted straight out of stories.

Add the shield, ax and six Royals (9-A), and that’s the full list of major symbols available here. The graphics quality is pretty good, one of the better titles from NextGen in that regard.


NextGen is one of the subsidiaries owned by NYX Interactive, a giant in the gambling niche, with both land-based and online operations. It’s been this way for over a decade, though NextGen’s history goes back a lot further, all the way back to 1999.

They had plenty of popular titles in the past, and these days they continue to put out exciting content, often enough with high volatility, just like in Rise of the Mountain King.

How To Play It

$0.30 to $15 is the complete betting range available, always using 30 coins in order to cover 30 lines. You get coin values between $0.01 and $0.50, as you change the bet.

The Buy Bonus option is present, and it costs 100x the stake, or 50x the stake if you take the 50/50 gamble.

The game area is regular, with 5×3 reels & 30 paylines. It’s not that much more complicated to play when it comes to features, though there are several there, and they’re fairly interesting.

Special Features

The King symbol is the one which acts as the wild, by which I mean that it has a role that a Joker would have in some card games. You can have it replace a regular symbol, being part of lower value winning combinations when it lands in the right position.

Have 3+ wilds appear, and the game will trigger a free re-spin, for which the triggering symbols are sticky. Scatters are also used as wilds, for the re-spin feature. To have more re-spins triggered, you need extra wilds appearing on the reels. Those will also become sticky wilds.

The name that they’ve given to the free spins feature is Rise of the Multiplier. It’s accessed when 3+ scatters appear on the slot’s reels, at random, with 8 to 10 rounds offered next. Up to 500x the stake is also paid, if you have up to 5 Ruby scatters.

As you collect scatter symbols, you can increase the multiplier of the wild King, to as much as 100x. You can see the status of the collection counter, in a special meter, and the triggering scatters are added to it as the feature begins, so there is a 5x wild multiplier available immediately. Get to 6 scatters to have the wild multiplier at 10x, to 9 scatters to get it at 15x, and so on. To get the 100x wild multiplier, you need to collect 18 scatters.

Maximum Payouts

Rise of the Mountain King is a game with very high volatility, which is how it can afford to pay up to 50,000x the stake. Not the kind of reward that a lot of people can expect to get, but the slot has a high risk/high reward type of gameplay that some players prefer. The Return to Player is the one that tells us how fair it is overall, and at 96.31% I’m satisfied with what I’m seeing.


Rise of the Mountain King is going to be recommended to players that have a high tolerance for risk, as its excellent 50,000x top jackpot doesn’t come easily. It’s a category that is increasingly popular, and this slot has a decent shot at getting a piece of that niche.
