How Thunderstruck II Works

  1. Base spins feed Microgaming feature pays around the Thunderstruck II identity. Exact free-spin rules sit in the paytable for your lobby build.
  2. Free spins concentrate larger outcomes under paytable-specific modifiers. Read that card once before the first real-money session.
  3. The 8,000× ceiling is the listed class in our catalog. Treat it as a rare top, not a session expectation.
  4. Medium-vol dry spells still happen. Confirm ~96.65% on the cash panel before you raise stakes.
