Play Treasures of Mjolnir Slot Game

There’s no shortage of Norse-themed online slots out there, but Pear Fiction Studios decided to swing Mjolnir just one more time, for now. Built around Thor’s hammer and some very charged bonus mechanics, Treasures of Mjolnir leans on progressive Wild Burst effects, jackpot coins, and a fancy feature unlock meter that evolves as you go. There are 20 paylines, plenty of electric zones, and more mythological beards than you hoped for.  

This Heart Bingo casino game has that cool, northern stillness to it, complete with pine trees and occasional cinematic clouds. The grid is framed in gold, with Mjolnir standing watch on the left. The reels are dark and dramatic, which only helps the symbols pop out. As for sound, it’s a folk score with a brooding undertone, and it does the job well enough.  

Here’s how the symbols stack up, starting with the lower-paying icons and moving up: 

Special Symbols 

Wild Symbol: Substitutes for all symbols except Gems, Jackpot Coins, and Bonus symbols. Wilds can trigger various Wild Burst effects.  

Gem Symbols: Collect one on each reel to trigger the Bonus Wheel.  

Bonus Symbols: Fill pots above the reels to unlock different LockNWin tiers.  

Jackpot Coins: Trigger the Jackpot Wheel and grow respective jackpot values. 

Wild Burst Feature 

Every 50 base game spins unlocks a new Wild Burst modifier. These start simple and potentially get more potent as you go. Regular Thunder turns a zone into Wilds, while Double Thunder adds another Burst symbol. Once unlocked, features like “Respin Burst,” “No Low Burst,” and “Multiplier Burst” can bring bigger effects like symbol removal or stacked wilds with multipliers.  

UpZones LockNWin Feature 

This is the jackpot-style coin feature that can trigger randomly when Bonus symbols are collected. There are four versions, Bronze, Silver, Gold, and Diamond, each with their own number of UpZones and spins. You get a shot at upgrading tiers through a gamble mechanic, though Diamond can’t be gambled. The main aim here is to land Coin symbols into UpZones, which could then activate effects from the top reel like coin collections, multipliers, spin boosts, or jackpot triggers. 

Bonus Wheel 

Collecting one Gem on every reel lights up the Bonus Wheel. This spins and awards one of the four LockNWin feature types. Gems don’t need to land in a single spin and can be collected over time. 

Jackpot Wheel 

This one activates when you land Jackpot Coins, each linked to Mini, Minor, Major, or Mega prizes. Once triggered, the Jackpot Wheel guarantees one of the fixed jackpots. These grow when additional coins land and reset once claimed. 

Treasures of Mjolnir plays on a 5x4 grid with 20 fixed paylines that pay from left to right. Wins require three or more matching symbols starting from reel one. Special features like Wild Bursts and UpZones LockNWin play out across the base game and feature spins, while modifiers, coin values, and jackpots come into effect through specific symbol combinations. 

If you like the Norse mythology angle, you might want to check out a couple more slots at Heart Bingo: 

• Trident of Legends: Still in the mythological genre, this Stakelogic title that also uses feature unlocks but then adds a cascade mechanic in there for good measure. 
• Kraken’s Catch: Focuses more on collection features and multipliers but it still brings a similar coin payout structure. 
• Might of Olympus: A release from IGT, this slot plays with a Ca$hLink feature and free spins with a slightly chaotic reel format. 

Treasures of Mjolnir does a solid job balancing out traditional mechanics with some of its more ambitious features, like the Wild Burst meter, which brings a nice bit of progression to the game. That said, players familiar with Pear Fiction’s other titles might spot some recycled elements, especially in the LockNWin side of things. Still, it’s a well-designed game with solid pacing, especially for those into Norse mythology and base game modifiers that actually add value.
