Ragnaravens WildEnergy

Yggdrasil Gaming sets Ragnaravens WildEnergy inside Norse mythology, pairing the brothers Thor and Loki on a 6-reel, 3-row grid worth 729 ways to win. The base game occupies a calmer version of the realm, split between an Asgard-like side and the icy domain of Niflheim, before free spins tip the whole scene into fire and destruction. Wins pay both directions here — left to right from the far-left reel, and right to left from the far-right reel.

Eight symbols make up the pay table: four Norse-pattern icons as the low end, with a helmet, a shield, an axe and a spear making up the premium set. Six matching low symbols across a way pay 0.6x the stake, while six matching premiums pay between 1x and 1.5x.

Two wild types carry the feature set. Raven Multiplier Wilds land only on the second or fifth reel; landing a win with one triggers a run of respins that continues for as long as the wild keeps contributing to winning combinations. The wild stays sticky through this, and its multiplier — starting at 1x — climbs by 1 with every win it's part of. Two Multiplier Wilds on the reels at once each add their own point to the total, and any wilds positioned on the centre reels add a further point each, a combination the game calls a Wild Combo. A spin that produces no win resets the multiplier back to 1x.

Thor and Loki Countdown Wilds work differently, landing only on the third or fourth reel. A win involving one also starts respins, but this wild is sticky for a fixed number of turns — 2, 3 or 4, shown as a countdown on the symbol itself — and stops granting respins once that count reaches zero.

Scatters can land on any reel except the two outer ones. Three of them award 7 free spins, and four award 10. The free spins round carries more wilds than the base game, and — unlike in the base game — a Multiplier Wild's accumulated multiplier does not reset between spins during the feature, only resetting once free spins end. Scatters themselves don't appear again once the bonus has started.

Players can also buy directly into the feature for 100x the stake, which randomly awards either 7 or 10 free spins. Ragnaravens WildEnergy is a high-volatility game returning 96% RTP at its top setting, with 94%, 90.5% and 86% configurations also available, a hit frequency of 32.71%, and a maximum win of 10,000x the stake across bets from 0.10 to 100.
