How it plays (base game, pays & Wild Bursts)
Layout & lines. You’re on a classic 5×4 / 20-line grid. Wins pay left-to-right and the paytable leans on Norse iconography (Valkyrie, Odin-like figure, raven, horse; royals for lows). The presentation is trademark PearFiction: saturated art, crisp animation, weighty SFX.
The Wild Burst system (the “evolving” engine)
At the top of the reels sits a spin counter that gradually unlocks six Wild Burst effects. Once all six are active, any Wild Burst can fire on a given wild—so the game accelerates the longer you play.
- From the start:
- Electric Zone: creates a charged area; symbols inside convert to wilds.
- Double Thunder: spawns a second Wild Burst and a second zone.
- Unlocks as you play:
- Respin Lock (≈50 spins): holds wins/wilds, respins rest.
- No Lows (≈100): removes low pays to refresh the grid.
- Wild Stacks (≈150): 1–3 reels turn stacked wild; wilds on them get ×2.
- Multiplier Upgrade (≈200): turns wilds into ×2–×10 multipliers (additive).
Why it matters: this staged unlock keeps early sessions varied and later sessions spiky (stacked wilds and multipliers can combine). If you like compounding modifiers, this is the hook.
Bonus Pots → UpZones Lock’N’Win™ (the coin game with tiers)
During base play you collect Bonus symbols into Bronze / Silver / Gold / Diamond pots above the reels. Filling a pot can trigger a tiered UpZones round; you may gamble Bronze/Silver/Gold to jump a tier (Diamond cannot be gambled).
Tier rules & starting power:
- Bronze: 3 spins, 3 UpZones
- Silver: 4 spins, 4 UpZones
- Gold: 5 spins, 5 UpZones
- Diamond: 6 spins, 6 UpZones
Gamble success chances are published by third-party reviewers at approx. 57.85% / 59.71% / 66.54% for Bronze/Silver/Gold respectively.
How UpZones works: coins drop only in this feature. Landing a coin in an UpZone also spins a top row that can add more UpZones and/or award one of five boosters: **Collect All, Coin Boost (+1× to +25× bet to all coins), Random Coin Multiplier (×2–×100), +Spins (+2–3), or the Jackpot Trigger. Round ends when spins run out or the grid fills.
The Jackpot Wheel (fixed prizes that grow as you play)
Collect Jackpot Coins in base game to charge the Jackpot Wheel; a spin guarantees one of four fixed prizes that scale as coins land until won:
- Mini: 10× → 25× cap
- Minor: 25× → 100× cap
- Major: 250× → 500× cap
- Mega: 2,500× → 5,000× cap
When a jackpot is won it resets to its start value. You can also back-door the wheel via UpZones “Jackpot” or via the Bonus Wheel Instant Trigger (collect 1 green gem per reel; five gems spin the wheel immediately).
Bonus Buy menu (transparent & tiered)
If your jurisdiction allows it, you can buy straight into an UpZones tier:
- Bronze: ~36.5× bet → 3 spins / 3 UpZones
- Silver: ~62.5× bet → 4 / 4
- Gold: ~104× bet → 5 / 5
- Diamond: ~156.5× bet → 6 / 6
- Mystery: ~42× bet → random 3–6 spins / 3–6 UpZones
RTP, volatility & hit rate — and what they mean for you
- RTP versions: 96.01%, 94.02%, 92.02%. Always check the in-game info at your casino; we recommend sticking to 96.01% where available. Learn how RTP works here: RTP. PearFiction Studios
- Volatility: Provider lists medium; third-party tests frame it as high-feel due to stacked wilds and multipliers. Expect stretches of build-up punctuated by bigger spikes from Wild Stacks/UpZones. Brush up on variance here: Volatility.
- Hit frequency: ~21.21%, i.e., roughly 1 in 4.7 spins pays anything—typical for modern feature slots.
Side note: Modifiers don’t change the underlying RNG; they reshape distribution (how often small/medium/large wins cluster).
Max win realism & bankroll planning
Top prize is 5,000×—achievable via Mega Jackpot or stacked wild/multiplier setups in rich Wild Burst sequences. That’s solid but not sky-high by 2025 standards. If you’re chasing once-in-a-runway results, there are bigger ceilings; if you prefer layered gameplay with multiple routes to “good” wins, this fits. See: Max Win.
Bankroll tips (quick math):
- Expect long unlock arcs (to reach all six Wild Burst effects). Bring 150–300 bets if you like to “see it all” in one sitting.
- Use consistent stakes and give UpZones a few cycles; the Jackpot Wheel builds over time.
- Keep a stop-loss and use built-in casino tools: deposit limits, reality checks, cool-offs (Responsible Gambling).

Pros & cons
What shines
- Distinct Wild Burst ladder keeps base play evolving (zones → stacks → multipliers).
- UpZones Lock’N’Win™ is a snappy coin feature with meaningful boosters.
- Jackpot Wheel provides steady side-progress and multiple trigger paths.
- Clear Bonus Buy menu with fair disclosure of starting power.
Trade-offs
- 5,000× ceiling will feel modest to max-win chasers.
- Needs a longer session to unlock all Wild Burst powers (or accept partial kit).
- RTP ranges mean version vigilance is required.
Who will like it / who won’t
You’ll likely enjoy this if you:
- Love modifier stacks that snowball (zones → stacks → multipliers).
- Prefer 20-line clarity over thousands of ways. See: Ways to Win.
- Want multiple routes to bigger hits (Wilds, UpZones, Jackpots).
You might skip it if you:
- Want super-high ceilings (≥10,000×).
- Dislike RTP ranges or longer ramp-up mechanics.
How it compares to recent PearFiction titles
Reviewers note the studio’s familiar “layered features” cadence—think Betbarian Bounty or 3 Lucky Gators—but here on a simpler 20-line canvas rather than “thousands of ways.” If you liked PF’s vivid art and compounding modifiers before, Treasures of Mjolnir delivers that vibe with a tidier grid.

Treasures of Mjolnir Slot Review – Verdict
Treasures of Mjolnir is PearFiction doing what it does best: layered modifiers that crescendo into punchy, highlight-reel moments. The UpZones bonus feels modern and Wild Bursts keep base game fresh beyond the first 100 spins. The trade-off is a 5,000× ceiling and an unlock arc that rewards longer sessions—great if you enjoy progression, less ideal if you want instant fireworks or ultra-high caps. Overall: A polished, feature-rich 20-liner that’s easy to recommend to fans of stacking wild systems and coin features.
Conclusion
Treasures of Mjolnir nails PearFiction’s signature: a clean 20-line canvas powered by layered modifiers that actually build toward bigger moments. The Wild Burst ladder keeps the base game from going stale, UpZones Lock’N’Win™ adds a modern, pacey hold-and-win with real decision points, and the Jackpot Wheel gives you a tangible “progress track” between bonuses. The trade-offs are clear: a respectable—but not headline—5,000× max win and a progression arc that rewards longer sessions (or selective Bonus Buys). If you enjoy stacking wilds, additive multipliers, and coin features, this is an easy recommendation—just prioritize the 96.01% build, bring a realistic bankroll, and set limits before the thunder rolls.
