Ragnaravens WildEnergy

Yggdrasil brings back Norse siblings Thor and Loki for Ragnaravens WildEnergy, setting the base game in a calmer stretch between Asgard and the icy reaches of Niflheim before the free spins round turns the sky to fire. The 6-reel, 3-row grid pays across 729 ways, and unlike most ways-to-win slots, combinations count both left to right from the first reel and right to left from the last.

Eight symbols make up the paytable: four Norse-pattern low pays sit beneath four higher-value icons, a helmet, a shield, an axe and a spear among them. Six matching low pays across a way return 0.6x the stake, while six of the higher symbols pay between 1x and 1.5x. Bets run from 0.10 up to 100 per spin, and the base RTP is 96%, with 94%, 90.5% and 86% configurations also in circulation depending on the operator.

Two wild types drive the respin mechanics. A Raven Multiplier Wild shows up only on the second or the fifth reel; a win that includes it starts a respin sequence that continues for as long as the wild keeps contributing to wins, and it stays sticky throughout. Each time it lands in a winning combination its multiplier rises by 1, starting from 1x, and if two Multiplier Wilds are present together, called a Wild Combo, each one adds its own +1, including any that land on the centre reels. A losing spin resets the multiplier back to 1x.

Thor and Loki Countdown Wilds work differently, landing on the third or fourth reel and staying sticky for a fixed 2, 3 or 4 respins, shown as a number on the symbol itself that counts down to zero before the wild expires.

Scatters can land on any reel except the outermost two. Three of them award 7 free spins, and four in view award 10. The free spins round keeps the wild respin mechanics active and carries the Multiplier Wild's running total into the round without resetting it, though scatters themselves don't appear once free spins begin, so the round can't be retriggered from inside itself. A Buy Bonus option is also available, paying 100x the stake for a randomly assigned 7 or 10 free spins.

With 32.71% hit frequency, high volatility and a 10,000x ceiling, Ragnaravens WildEnergy leans on its two wild types to build value across a spin rather than paying out steadily. Most of its swing comes from how many respins the Raven and Countdown Wilds can chain together before a losing spin resets the count.
