With blockbuster films like Thor and smash series such as Vikings proving big hits with the general public, it’s no surprise to see Viking-themed slots coming at us like thrown axes on the battlefield. And surely no studio is better placed to draw on their environment and history than Swedish slots house, NetEnt. The world-leading slots developer revives its legendary Avalanche™ feature, made famous by everyone’s favourite 3D sprite Gonzo in Gonzo’s Quest. There is much more to look forward to in this five reel, 20 payline slot, including Colossal Symbols, a Colossal Crush feature, Multiplier Meter and Free Spins bonus game. In true Viking style, it’s going to be epic.

Gameplay

The action takes place at the gates of Valhalla. Old Norse Gods runes of various colours make up our high-paying game symbols, while lower-payers take form in rugged-looking Queens, Kings and Aces. All symbols can appear as Colossal Symbols, sure to complete several winning combos in one spin. Wild Ws complete winning paylines where there were previously none, in both the base game and the Free Spins bonus feature. When we score winning paylines, they come alive with electric blue fire and explode in blue flame, allowing the Avalanche™ feature to send more symbols down onto the reels like thunderbolts from Thor himself. Should more winning combinations form, they too will explode and leave space for new symbols and new combinations.

Bonuses

Unlike Gonzo’s Quest, we won’t enjoy additional multipliers for every win we score. The Multiplier Meter resting by the side of the reels belongs solely to wins from the Colossal Crush feature, which sees a Colossal Symbol land on the top row and crush all symbols beneath it, row by row. With each row they crush, they add a multiplier level on the Multiplier Meter – x2, x3 and x4. A Colossal Symbol win with a x4 multiplier? A sweet bonus sent by the Gods, indeed.

Rather than bother with additional Scatter symbols, the Asgardian Stones online slot instead includes a 3×3 Bonus Wheel that can land at any time. Following any Avalanche Wins that occur when the Bonus Wheel lands, the wheel spins to award either free spins or coin wins. The wheel contains three awards of five free spins, but the awards we land depend on how many rows the Bonus Wheel covers. There are three winning positions on the Bonus Wheel, so if the Bonus Wheel covers all three rows it will award three sets of five free spins – 15 free spins – if the free spins symbols land in the three winning positions. We could win three coin win amounts (up to a max multiplier of x36 our stake) or a combination of coin wins and free spins.

Summary

With all the talk of Bonus Wheels with no set amount or guarantee of free spins, you might surmise the Asgardian Stones slot to be complicated. Not so. Such is the degree of visual excellence that netEnt achieves with this slot that the multipliers, Colossal Crush and Bonus Wheel become self-explanatory through the gameplay. Asgardian Stones is another superbly atmospheric slot release from NetEnt with great win potential.
