Reign Of The Mountain King

Reign Of The Mountain King is an Edvard Grieg-inspired online slot from SG Digital, following on from an earlier release built around the same classical theme. Where that predecessor leaned into a sweeping, cloud-based setting with a soaring metal rendition of Grieg's In the Hall of the Mountain King running through it, this sequel takes a noticeably more restrained approach — the action now plays out inside the Mountain King's castle, and across the board, from the mechanics to the presentation, things have been dialled back rather than escalated.

The 5-reel, 3-row grid runs across 10 fixed paylines, down from the wider payline count of the earlier release, with wins formed when at least three matching symbols land left to right from the first reel. There are no scatter symbols and no separate bonus round here — instead, everything revolves around the game's wild King symbol, which substitutes for any other icon and can trigger a respin feature when the right number land. On regular spins, if a single wild forms part of a four or five-of-a-kind win, it can carry a multiplier of x5, x8, x64 or even x512, giving the base game a genuine chance at a serious hit without needing a dedicated feature round to get there. The regular pay table runs from 9 to Ace card royals up through axes, shields and trolls, with the Queen as the top standard symbol.

RTP sits at a respectable 96%, only a touch below the earlier release's figure, and volatility remains rated high, so this is still very much a game built for players comfortable with some swing between spins. The max win is set at 10,000x the stake, and betting runs from 10p/c up to $/€10 per spin, keeping it accessible even at the lower end of the stake range.

It's an interesting design choice for a sequel — where many follow-ups try to top the original with bigger numbers and more layered features, SG Digital has gone the other way, betting that the wild-multiplier mechanic alone is strong enough to carry the game without a separate bonus round propping it up. Judging by the win potential still on offer here, that bet largely pays off, even if it does mean less visual spectacle along the way.

Reign Of The Mountain King trades some of its predecessor's visual grandeur and feature complexity for a tighter, more streamlined structure, with the wild-multiplier system doing most of the heavy lifting. It's a leaner, more focused sequel rather than a bigger one. Worth checking the free demo at Johnessyslots to see how the stripped-back Reign compares before playing with real stakes.
