The ThunderStruck name has echoed through online casinos for years because it found the perfect storm of mythology, volatility and feature-rich gameplay. Before diving into ThunderStruck Storm Blitz at bet365 Casino, it’s worth revisiting why earlier ThunderStruck titles became long-standing favourites among slot players.

Why ThunderStruck Slots Became So Popular
ThunderStruck (Original Release)
The original ThunderStruck leaned into Norse mythology with bold visuals and accessible gameplay. It was easy to understand yet had enough bonus intrigue to keep sessions engaging.
ThunderStruck II
ThunderStruck II elevated the series with more layered bonus features and expanded mythology. It became a go-to recommendation for players who wanted classic structure with modern bonus potential.

ThunderStruck Storm Blitz at bet365 Casino – Overview
Game: ThunderStruck Storm Blitz
Reels: 5
Paylines: 30
RTP: 92.50% (bet365 version)
Volatility: High
Features: bonus spins, Bonus Games
If you’re comparing RTPs across games at bet365 Casino, our overview of Amatic Slots at bet365 is useful for side-by-side comparisons of different volatility and return profiles:
Theme & Presentation
Storm Blitz keeps the Norse mythology aesthetic but sharpens it for modern slot audiences. Expect dramatic lighting, metallic accents and thunder-charged sound design.
The tone fits the volatility. This is not a gentle session slot. It is built around feature anticipation and swing potential.
Base Game Mechanics
The game runs on a 5-reel, 30-payline structure, with wins landing left to right across active paylines.
High volatility means:
- Base game wins can be less frequent
- Feature triggers carry more weight
- Session results often hinge on bonus performance
If you prefer a slightly more balanced volatility profile, you might also look at Bells on Fire at bet365 Casino, which offers a different risk-reward dynamic:
Symbols & Paytable Breakdown
Like previous ThunderStruck titles, Storm Blitz leans heavily into Norse mythology for its premium symbols while using classic card ranks to structure the lower-paying combinations. Understanding the symbol hierarchy is important in a high volatility slot, because premium symbols are often the difference between a modest hit and a session-changing win.
Below is a breakdown of what you can expect on the reels.
Premium Character Symbols
The highest-paying symbols are the mythic figures drawn from the ThunderStruck universe. These typically include:
- The Viking Warrior
- The Valkyrie
- The Bearded Norse King
- The Armoured Champion
Landing five of the top premium symbol across an active payline delivers the strongest base game payouts. In high volatility slots like Storm Blitz, these premium combinations are rarer — but when they land in clusters during bonus spins, they can produce significant returns.
Premium symbols become especially important during bonus rounds, where enhanced mechanics can amplify their impact.
Wild Symbol
The Wild symbol substitutes for all standard paying symbols to help complete winning lines.
Key points about the Wild:
- It can replace premium and low-paying symbols
- It cannot substitute for Scatter symbols
- During bonus spins, it may carry additional functionality depending on the bonus variation
In a 30-payline structure, Wild positioning is critical. A single Wild on reel 2 or 3 can unlock multiple paylines at once, dramatically increasing payout potential.
In high volatility games, Wilds are often more impactful but less frequent than in medium volatility slots.
Scatter Symbol
The Scatter symbol is the gateway to the game’s headline features.
Typically:
- 3 or more Scatters trigger bonus spins
- Scatters can pay anywhere on the reels
- Additional Scatters during bonus rounds may retrigger features
Because Storm Blitz is feature-led, landing Scatters is where the momentum shifts. In many sessions, the bonus spins round will determine overall outcome.
Bonus Symbols
Storm Blitz also incorporates bonus-specific symbols that activate additional mini-games or special feature sequences.
These may:
- Trigger pick-style bonuses
- Unlock enhanced reel modifiers
- Introduce multipliers
Bonus symbols add depth beyond standard bonus spins and help differentiate Storm Blitz from earlier ThunderStruck titles that relied more heavily on single-layer bonus structures.
Low-Paying Symbols (Card Ranks)
As with most modern slots, lower-paying symbols include traditional card ranks:
- A
- K
- Q
- J
- 10
While these deliver smaller payouts, they play an important structural role. During bonus spins, when multipliers or reel modifiers are active, even card rank combinations can become more meaningful.
Low symbols are also useful for building layered wins when combined with Wild substitutions.
Symbol Volatility Impact
Because this is a high volatility slot, you should expect:
- Premium symbols to land less frequently in the base game
- Wilds to have stronger impact when they appear
- Bonus-triggering symbols to be the main driver of large wins
The symbol design supports the volatility profile. This is not a “steady trickle” paytable — it is built around spikes.
If you compare this structure to something like Bells on Fire or even Kong 3 Even Bigger Bonus, you’ll notice Storm Blitz leans further toward bonus-dependence rather than base-game consistency.
Final Thoughts on Symbols
Storm Blitz uses a classic hierarchy:
- Premium Norse characters
- Wild substitution power
- Scatter-triggered bonus spins
- Bonus symbols for added feature depth
- Card rank fillers
It’s a straightforward structure on paper, but the high volatility engine means symbol interaction becomes far more dramatic inside bonus rounds.
Understanding how these symbols work together will help you interpret session swings and recognise when a feature round has strong potential.
bonus spins Feature
bonus spins are central to Storm Blitz. This is where the slot justifies its volatility profile.
During bonus spins, expect:
- Enhanced winning potential
- Greater impact from premium symbols
- Higher session-defining moments
High volatility slots often concentrate their largest wins into bonus rounds, similar to how Jackpot365 slots operate within bet365’s progressive network. You can read more about those mechanics in our dedicated Jackpot365 guide.
Bonus Games
Storm Blitz also incorporates additional bonus mechanics beyond standard bonus spins. These bonus sequences typically introduce:
- Modified reels
- Pick-style features
- Enhanced symbol behaviour
Feature-driven gameplay is something we often highlight in our reviews, particularly in slots like Ultra Seven and Wild 7 from the Amatic range, which you can find reviewed in our Amatic slots feature above.
RTP & Volatility Explained
RTP – 92.50%
At 92.50%, this is lower than many mainstream slots at bet365 Casino. RTP does not predict short-term outcomes, but it matters over extended play.
If RTP is your priority metric, comparing games through our full bet365 slot review archive on BonusCodePoker.com can help you find alternatives with higher listed returns.
High Volatility
High volatility means:
- Larger swings
- Bonus-dependent results
- Longer dry spells balanced by stronger spikes
This is similar in behaviour to some Blueprint high-volatility titles such as Kong 3 Even Bigger Bonus, which also concentrates potential into feature rounds.
Playing Strategy & Session Tips
ThunderStruck Storm Blitz is not built for low-risk grind sessions. Consider the following approach:
1. Stake Management
Choose a stake that allows for a significant number of spins. High volatility can create extended low-return sequences.
2. Feature-Focused Mindset
Treat this as a “feature hunt” slot. The value is in bonus rounds.
3. Mix with Lower Volatility Titles
If you enjoy theme continuity but want smoother sessions, alternate with slots like Bells on Fire or browse our bet365 slot section for mid-volatility alternatives.
4. Set Clear Limits
As with all slots, set deposit and session limits before playing.

Final Verdict
ThunderStruck Storm Blitz delivers what its name promises: dramatic, feature-driven gameplay built around high volatility swings. It suits players who:
- Prefer bonus-heavy sessions
- Enjoy Norse mythology themes
- Are comfortable with variance
It may not suit players seeking steady, frequent base game payouts or higher RTP configurations.
