Introduction to Wildhalla

Wildhalla is a casino slot from Slotmill that takes you on a voyage aboard a Viking longship in the company of a team of fearless Norse warriors. Uncharted lands full of precious spoils await, and it's time for some good-old pillaging to the tune of pounding drums, heroic chanting, and clanging steel. In this casual, cartoony depiction of the Middle Age conquests, you'll be relying on the wild nature of the Northmen, who become Walking Wilds equipped with potential multipliers whenever they land on the grid. As they traverse the reels, you can enjoy multiple free respins, and when the fighters combine their powers in a single combination, their multipliers multiply to make the loot so much more valuable. During Free Spins, you'll experience an entire column of four Vikings marching side by side, with the possibility to add more to the army, as well as resetting them back to the beginning when the war horn sounds.

Theme, Gameplay & Payouts

Wildhalla is a video slot from Slotmill with 5 reels, 4 rows, and 40 paylines. The range of available betting options starts from a Min.bet of 0.20 and goes all the way up to a Max.bet of 100. You can increase that value further by using the Xtra Bet feature, bringing it up to 200. The game offers a default RTP of 96.05%, which is on the lower end of the industry average. Additionally, there is one alternative variant of 94.16% also available for operators, so be sure to check your version before playing. You can expect higher wins to be further apart but more valuable on average when you score a hit due to high volatility, while the max win achievable in a single round is 10,000x the bet.

Wildhalla's main scene is set at the shore, where Vikings have anchored their longship and disembarked to loot the nearby castle. There are signs of a fight on the beach, where swords, spears, shields, and pieces of armour lie scattered around. An ominous crow sits on the hilt of one of the weapons, as if standing guard as fallen warriors travel to the afterlife. The design clashes soft, cartoon aesthetics with a relatively grim atmosphere, additionally amplified by a sublime, marching soundtrack. The entire picture feels clean and consistent, plus its responsive nature allows the game to be played on a wide range of devices, from desktops to smartphones and tablets.

In the paytable, you'll find regular symbols split into two categories. To achieve a win, you'll need to connect at least 3 matching ones on any of the paylines while using neighbouring reels, starting from the leftmost one. The low-paying icons are represented by playing card ranks: J, Q, K, and A, which award 0.5x the bet for matching 5 on a pyaline. A headless fish, a tankard, a shield, and an axe represent the high-paying symbols, which bring payouts of between 0.75x and 1.5x the bet when you form a 5-of-a-kind hit. At the top of the hierarchy is a treasure chest, paying 3x the bet for a complete payline of 5. In addition, there are four types of Wilds represented by Vikings, Reset symbols in the form of silver and gold war horns, and Bonus symbols appearing as a tree on a golden tile.

Walking Wild Respins

Whenever you land a Walking Wild in any position on the grid, it initiates a respin sequence. The Wild itself may also appear with a multiplier of up to x16, which applies to any payline combinations with its participation. When a Wild becomes a part of a win, its multiplier grows by 1 before the next respin. If more than one Wild contributes to a win, their multipliers are multiplied by each other before being applied to the payout. All Wilds present on the board move one position left per respin until they reach the left edge of the screen and transform into a regular symbol. Respins continue as long as there is at least one Walking Wild present on the grid.

Reset Symbol

Reset symbols appear only on reel 5 as silver and gold war horns. Both of them make the Wilds move back to the fifth reel. The silver one affects only Wilds on the same row, while the gold one affects all Wilds present on the grid.

Bonus & Super Bonus Respins

Bonus and Super Bonus symbols appear only on reels 2, 3, and 4. Landing a set of 3 regular ones or 2 regular and 1 Super triggers the Bonus or Super Bonus Respins round, respectively. Each mode begins with a full stack of 4 Walking Wilds placed on the fifth reel and continues as long as there's at least 1 Walking Wild in view. In the Super variant, multipliers on Wilds grow by 1 with every spin, regardless of whether they participate in a win.

Final Thoughts on Wildhalla

Ah Vikings! Not only were they feared during the Middle Ages because of their bloody conquests, but they also managed to successfully permeate the online slots scene, becoming one of the more popular subject matters. Since the beginning of iGaming, they've been appearing regularly in nearly all providers' portfolios, sometimes in serious settings like the TV show-inspired Vikings by NetEnt, and other times in lighthearted depictions like Le Viking by Hacksaw Gaming. Slotmill's Wildhalla falls somewhere in between, on the one hand, presenting a relatively grim scene of the aftermath of a brutal battle, but balancing it with a clean, comic book-style artwork. Despite being relatively generic with its content, the theme is well-done, showing the studio's usual expertise, although not being as energetic and lavish with the effects as, say, Lucy Luck and the Quest for Coins. Still, the clean execution and a bit of quirkiness brought by the frenzied Viking characters make up a pleasant and consistent experience.

From a technical standpoint, you could say that the game holds a comparable level of novelty to its theme. It's a tight setup, revolving around one core feature, yet pumped up with some extras that elevate it above its basic, familiar format. Respins with Walking Wilds have been around for years, since the iconic Jack and the Beanstalk by NetEnt. They have also undergone numerous fusions with other mechanics, so there's a good chance there's already something similar to Wildhalla out there. Still, the robust effect that the increasing multipliers have on this feature can be exceptionally gripping, especially thanks to their multiplicative nature that can create a genuinely insane boost. Reset symbols are also a perfect supplement here, dragging the Wilds back to the fifth reel to allow for even higher growth. It might not be the most original setup in general, but we can't ignore its raw power and engaging potential.

Wildhalla skilfully combines Walking Wilds with increasing multipliers to deliver straightforward yet potent gameplay in a clean, cartoony Viking theme.
