Thunderstruck II screenshots
Original game imagery from our sister site KeyToCasinos. Screens and displayed rules checked on 6 October 2026. These are historical interfaces; operator branding and older controls do not establish current availability.
How Thunderstruck II works
Three, four or five hammer scatters enter the Great Hall of Spins. Its features unlock after successive bonus triggers. Wildstorm can randomly turn up to five reels wild, but free spins cannot trigger during Wildstorm. The ordinary logo substitute doubles a win outside that feature.
These provider listings do not confirm that Thunderstruck II is currently offered. Check the exact game and access from your location with the operator.

Rules and payout examples
The examples below were checked against the original screens above. They are selected conditions, not a complete paytable or a promise about a current release.
| Combination or feature | Award or rule shown |
|---|---|
| Valkyrie: first trigger | 10 free spins; wins multiplied by 5 |
| Loki: fifth trigger | 15 free spins with Wild Magic |
| Odin: tenth trigger | 20 free spins; raven multipliers 2x, 3x or combined 6x |
| Thor: fifteenth trigger | 25 free spins; Rolling Reels multiplier up to 5x |
Read the award unit and any bet-setting condition together. Free spins count game rounds; a win multiplier applies to the specified win; a displayed paytable number is not automatically a multiple of the full spin stake. The exact in-game help governs how line bets, coin value and feature modifiers combine.
Edition and availability
This reference covers Thunderstruck II, not a sequel or another provider’s similarly named game. The historical interface may show controls or stake settings that are no longer offered. It does not verify a current RTP, operating limit or maximum cash prize. Consult the version you are using for those details.
Frequently asked questions
Are all Great Hall features immediately unlocked?
No. The photographed rules unlock Valkyrie, Loki, Odin and Thor at the first, fifth, tenth and fifteenth bonus triggers respectively.
Can Wildstorm also trigger free spins?
No. The original Wildstorm rules exclude a simultaneous free-spin trigger.
What is the pictured rule for valkyrie: first trigger?
10 free spins; wins multiplied by 5. This applies to the condition and setting shown in the reference table, not every possible game configuration.
Are these figures all multiples of the total stake?
No. The table distinguishes coin or displayed values, line-bet and total-bet multipliers, and awards counted as spins. Keep those units separate. A coin amount also depends on the selected coin value before it becomes a cash amount.
Do these screenshots prove Thunderstruck II is available today?
No. They document the pictured edition and its rules. Check the exact title in the operator’s current library and read its own help screen for present limits, payout settings and location restrictions.
