RagnaRavens WildEnergy: Slot Overview
Few sibling duos in mythology are as entertainingly tangled as the Norse brothers Thor, the powerful hammer-wielder, and Loki, the infamous trickster. Their rivalry is great fun when they’re at each other’s throats, but it’s even more satisfying when they set differences aside and join forces for a shared cause. The MCU leans hard into that stop-start brotherhood, and in RagnaRavens WildEnergy from Yggdrasil Gaming, the pair reunite once again—this time to the advantage of mythology-minded slot fans.
The base game of RagnaRavens WildEnergy unfolds in a calm, otherworldly setting, with what looks like Asgard on one side and the frozen reaches of Niflheim on the other. Once free spins kick in, however, the tone shifts as fire and ruin pour across the screen, suggesting the devastation of war. It’s a little bleak, honestly. If even divine brothers struggle to coexist, what chance do the rest of us have over the long haul? Still, RagnaRavens WildEnergy lives in Yggdrasil’s fictional universe—so perhaps reality has more resilience, resolve, and compassion than the myths imply. Also worth noting: it’s genuinely nice to see Yggdrasil finally ditch the dreadful UI; you no longer have to squint just to make out your balance or stake.

Moving on to the stakes, the bet range runs from 10 c to $/€100 per spin. Much like the brothers’ famously turbulent bond (at least in modern pop culture), RagnaRavens WildEnergy is highly volatile, with a default RTP of 96%. That RTP applies whether you’re playing normally or purchasing free spins. Action takes place on a 6-reel setup with 3-rows and 729 ways to win. On top of that, you can win both ways, meaning combinations pay left to right from the leftmost reels and right to left from the rightmost reel.
Wins require three or more matching symbols, and there are 8 regular pay symbols in total. Four are lower-paying Norse-style patterns, while the higher pays are a spear, an axe, a shield, and a helmet. A 6-of-a-kind line of low pays returns 0.6x the bet, while landing 6 matching high pays awards 1 to 1.5 times the bet.
RagnaRavens WildEnergy: Slot Features

RagnaRavens WildEnergy is a follow-up to RagnaWolves WildEnergy, and the gameplay overlap is substantial. In this entry, the feature set consists of Multiplier Wilds, Countdown Wilds, Wild Combos, free spins, and a buy bonus.
Multiplier Wild
Raven Multiplier Wilds may appear on the second or fifth reel. When a Multiplier Wild helps create a win, it triggers respins, and the Multiplier Wild becomes sticky. Respins keep going for as long as the Multiplier Wild remains part of a winning combination. Every win is boosted by the wild’s multiplier, which begins at x1 and increases by +1 each time it contributes to a win. If 2 Multiplier Wilds land at once, each one adds +1 to the multiplier, and any wilds on the centre reels also add +1 each. This interaction is called a Wild Combo. The multiplier resets following a non-winning spin.
Countdown Wilds
Thor and Loki Countdown Wilds can land on the third and fourth reel. A win involving a Countdown Wild also initiates respins, and these wilds stay sticky for 2, 3, or 4 respins. The number shown on the symbol indicates how many spins it will remain sticky. Once the count reaches 0, it stops granting respins.
Free Spins
Scatter symbols can land on every reel except the far-left and far-right reels. Landing 3 scatters awards 7 free spins, while getting 4 scatters on screen awards 10 free spins. Free spins contain more wilds, and wild respins can trigger just as they do in the base game. The key difference is that the Multiplier Wild multiplier does not reset during free spins. Scatter symbols do not appear during the free spins round.
Buy Bonus
Players can use the bonus buy to randomly receive 7 or 10 free spins for 100 times the bet.

RagnaRavens WildEnergy: Slot Verdict
With a name like Yggdrasil Gaming, you’d expect—at minimum—competence when it comes to Norse Mythology slots, and to be fair, the studio delivers with RagnaRavens WildEnergy. From a visual standpoint, it’s well put together with little to complain about, even if it arguably doesn’t feel quite as enchanting as RagnaWolves. Still, anyone who enjoys the Thor-and-Loki dynamic—the tension, the teamwork, and the contrast between their realms—should feel perfectly at home in this godly-looking release.
In certain respects, RagnaRavens WildEnergy doesn’t feel as wondrous as RagnaWolves overall, largely because the two games play so similarly that there’s not a huge gap between them. That makes the second outing less surprising. There are adjustments, but the standout moments in RagnaRavens WildEnergy still come via Multiplier Wilds, Countdown Wilds, respins, an escalating multiplier, and free spins. It’s strong content, but it’s also largely what players have already seen. The max win matches as well, sitting at 10,000 times the bet.
That’s still a solid target to chase, and the feature package in RagnaRavens WildEnergy holds up nicely. So, for Norse Mythology fans, it’s another dependable Yggdrasil Gaming slot to dig into. However, the absence of major new gameplay ideas that clearly separate it from the earlier title means RagnaRavens WildEnergy is enjoyable—just perhaps not essential for anyone who already got their fix from the previous game.
