What is Thunderstruck II?

It’s the sequel that hit harder than the original. Microgaming took the Norse gods — Thor, Odin, Loki, the Valkyrie — and dropped them onto a 243-ways engine. No lines to mess with. Symbols land next to each other from the left, you win. Simple. Fast. Relentless.

But the real reason your pulse spikes? Four separate bonus rounds, and each trigger levels you up to the next one. It’s a chase. And the chase is addictive.

How to play Thunderstruck II

Set your bet. Smash spin. That’s it. With 243 ways there’s nothing to fiddle with — your stake is locked and every spin is live. Want our tip? Fire off a few demo spins to feel the tempo, then let it rip for real.

Wild Storm — out of nowhere

Any spin. No warning. Wild Storm blasts up to all five reels wild and suddenly you’re staring at a monster hit you never saw coming. This is the base-game adrenaline shot.

Features & bonus round

Three or more of Thor’s Hammer and you’re INTO the Great Hall of Spins. First trip: Valkyrie — 10 spins, 5x multiplier baked in. Trigger again and Loki kicks the door open with Wild Magic rolling reels. Again? Odin storms in with Wild Ravens firing multipliers. And then — THOR. Rolling reels, a multiplier that climbs to 5x on back-to-back wins, the whole storm let loose. Once all four are unlocked you PICK your battleground. Every trigger builds toward the big one. That’s the hook that keeps you spinning.

Graphics, sound & theme

Sure, it launched in 2010, so it’s not the shiniest slot on the shelf. Doesn’t matter. The thunder claps, the reels roar, and climbing through the Hall of Spins still hits like a storm rolling in. The character art has bite and the audio absolutely delivers the drama. It’s got attitude, and attitude never goes out of style.

Pros

  • Four escalating bonus rounds — the chase is electric
  • Wild Storm can erupt on ANY spin

4.6/5  —  Our verdict

Thunderstruck II is a slow-build storm that pays off HARD. The four-tier bonus chase keeps the tension cranked, and every trigger drags you closer to the Thor round where the multipliers really let loose. Not the flashiest slot alive — but the rush is real. Spin it.
