Overview
By Sophie Lang, Games & Mobile Editor. Catalog RTP last refreshed 24 August 2026 — not a live lobby scrape. Confirm the cash info panel after login.
Thunderstruck II is Microgaming’s medium-vol Norse sequel: 8,000× class, prefer ~96.65% after CAD login. It is not Immortal Romance’s 3,564× vampire chambers (~96.86%) and not Dead or Alive’s 100,000× sticky-wild original (~96.82%).
Lobby search stacks Immortal Romance, Game of Thrones Power Stacks, and Dead or Alive beside it. Open the cash title that reads Thunderstruck II, then read the panel — reduced Microgaming builds still ship.
Confirm the live contribution table. Some tables still cap max bet. Confirm before you opt in.
Editor take — Thunderstruck II. Use the Norse sequel on a 96.65% CAD panel at 8,000×. Take Immortal Romance for vampire chambers at 3,564× / ~96.86%. Take Dead or Alive for the sticky-wild original at 100,000× / ~96.82%. Skip Game of Thrones Power Stacks unless that is the cash tile.
Stake and table limits for Thunderstruck II are operator-specific in CAD. Set a session cap before you open the game, then confirm 96.65% on the cash panel — not the demo tile.

Review FAQ
Thunderstruck II is the Microgaming Norse sequel with Great Hall free spins, an 8,000× class and a preferred ~96.65% CAD panel. The original is a shorter earlier title. Play II unless you specifically want the first game — confirm both cash panels after login.
Prefer about 96.65%. Operators can load reduced builds. Open the information screen on the real-money copy after CAD login; do not trust the demo tile.
Confirm the live contribution table. Older Microgaming titles are sometimes listed separately. Confirm “Thunderstruck II” without Wild Lightning in the title if the promo names this sequel only. Max-bet rules still apply in Great Hall free spins.
Both are Microgaming era classics. Immortal Romance is vampire chambers at 3,564× and ~96.86%. Thunderstruck II is Norse Great Hall at 8,000× and ~96.65%. Pick Norse vs vampire, then confirm RTP.
Cleopatra is Microgaming Egypt at a preferred ~95.02% panel and 1,000×. Thunderstruck II sits higher on both RTP and ceiling. Pick Egypt vs Norse, then confirm the cash panel — Cleopatra’s ~95% line is not the same as 96.65%.
Open Microgaming Thunderstruck II — not the original Thunderstruck, not Wild Lightning. Check the ~96.65% line and 8,000× class on the cash paytable.
Our catalog tags it Medium. Great Hall free spins can still swing a short CAD session. Size stakes for that class, not for a 100,000× hunt.
Thunderstruck II earns 8.2/10 as a 8,000× Microgaming Norse / Thunderstruck title — play it beside Immortal Romance for the Microgaming classic pair; switch to Dead or Alive when you want sharper classic high-vol. Verify the ~96.65% cash panel on a Canadian brand after login, then raise CAD stakes.
