Treasures of Mjolnir Game Features

Here’s what awaits beyond the base game in Treasures of Mjolnir:

Treasures of Mjolnir Wild Symbol Feature

When Wild symbols appear on the reels, they can take the place of any symbol except for Gem, Jackpot, and Bonus symbols. This makes them a great way to complete winning combinations.

Treasures of Mjolnir Wild Burst Feature

The Wild Burst Feature introduces a sense of progression by unlocking new gameplay modifiers as the Wild Burst tracker counts down. A list of features unlocks each time the Wild Burst counter above the reels hits zero, but you must still land a Wild Burst symbol to trigger a randomly chosen bonus.

Players begin with the Thunder modifier before gradually unlocking Double Thunder, Respin Wild Burst, No Low Symbols, Wild Stacks, and finally Wild Multipliers. These bonuses have effects varying from adding a few additional wilds to adding wild stacks and even boosting wilds with multipliers that increase wins by 10x.

Treasures of Mjolnir UpZones LockNWin Feature

The UpZones LockNWin Feature is triggered by landing the required Bonus symbols and can award one of four bonus tiers: Bronze, Silver, Gold, or Diamond. 

During the feature, Coin symbols lock in place to be paid out at the end of the feature. Additionally, landing Coins in special UpZones spins a special reel above the main grid. This reel can reveal bonuses, such as Collectors that instantly pay out all rewards, Multipliers that boost the value of a random coin by up to 100x, Extra Spins that increase your remaining number of spins, and Jackpots that give you a chance to trigger a spin of the Jackpot Wheel.

Treasures of Mjolnir Bonus Gamble Feature

You can choose to take advantage of the Bonus Game feature before the start of the LockNWin feature. This gives you a chance to gamble your current LockNWin tier (Bronze, Silver, or Gold) for a higher tier with extra spins and UpZones. 

Treasures of Mjolnir Bonus Wheel Feature

The Bonus Wheel is triggered when the Bonus Wheel gem symbol lands during the base game. Spinning the wheel randomly awards one of the four UpZones LockNWin Features, instantly sending players into the corresponding Bronze, Silver, Gold, or Diamond LockNWin bonus round. 

Treasures of Mjolnir Jackpot Wheel Feature

Landing the Jackpot Wheel symbol in this Microgaming slot game activates the Jackpot Wheel Feature, where a wheel spin randomly awards one of the Mini, Minor, Major, or Mega progressive jackpots. This provides a second route to landing the game’s jackpot prizes, independent of the UpZones LockNWin Feature.

Treasures of Mjolnir Buy Feature

Players who prefer immediate access to the bonus content can activate the optional Buy Feature before spinning. A popular option in many online casino games, this feature offers five purchase choices: Bronze (37.25x your bet), Silver (63.82x), Gold (106.35x), Diamond (159.83x), and Mystery (43.01x). Each option grants direct entry into its corresponding UpZones LockNWin Feature, while the Mystery option randomly selects one of the four available bonus tiers.

Treasures of Mjolnir Slot Bonuses and Jackpots

This online slot offers bonus and jackpot rewards. Bonus coin payouts can pay up to 100x your wager during the LockNWin feature. Jackpots can be awarded during both the LockNWin and Jackpot Wheel features. The jackpot prizes are the Mini (pays 10x-25x your wager), Minor (pays 25x-100x), Major (pays 250x-500x), and Mega (pays 2,500x-5,000x). These jackpot rewards have ranges because they can grow in size throughout the game. They all start with a base value and increase by 1x each time a Jackpot coin lands on the reels.  

How To Win Treasures of Mjolnir Slot

Wins in Treasures of Mjolnir begin by landing matching symbols across the game’s 20 fixed paylines, with Wilds substituting for most regular symbols to help complete winning combinations. Beyond the base game, the biggest rewards come from triggering the Wild Burst progression, UpZones LockNWin Feature, Bonus Wheel, and Jackpot Wheel, where players can collect instant cash prizes, multipliers, and the Mini, Minor, Major, or Mega progressive jackpots. With a maximum payout of 5,000x your total bet, its greatest winning potential lies within its layered bonus features rather than through line wins alone.

If you’re wondering do you win more if you play slots on max bet, this Microgaming slot game offers the same feature set across all eligible bet sizes, while higher wagers simply increase the value of any wins that are awarded. 

Treasures of Mjolnir Slot Graphics and Design

Treasures of Mjolnir is a visually striking themed slot that brings Norse mythology to life with richly illustrated Viking warriors, ravens, glowing runes, and the mighty Mjolnir taking center stage. Fans searching for the top-rated slots based on Norse mythology will appreciate its dramatic mountain village setting, where the reels are framed by fiery accents and illuminated Bonus Pots, while the ever-present Wild Burst meter and jackpot display reinforce the game’s sense of progression. 

The soundtrack matches the scale of the adventure, delivering an epic, grandiose score that feels worthy of a battle for the gods, complemented by booming thunder effects and satisfying audio cues that make every feature trigger feel suitably momentous.

Treasures of Mjolnir Slot Symbols

Based on $1.00 per spin, the Viking king is the highest-paying regular symbol, awarding $10.00 for five matching symbols on a payline. He is followed by the Viking queen at $4.00, the Viking warrior at $3.00, the raven at $2.50, and the horse at $2.00. The card-value symbols A, K, Q, and J each pay up to $1.00 for five of a kind, making them the lowest-value regular symbols on the reels. 

For fans of slots for real money, golden wilds and golden wilds with hammers symbols substitute for all regular symbols, four different colored Jackpot coins could activate the Jackpot Wheel, four different colored Bonus coins could activate the LockNWin feature, and lastly, gold and green Gems could activate the Bonus Wheel.
