Thunderstruck II RTP

Thunderstruck II is a Microgaming classic that drops you straight into Asgard alongside Thor, Odin, Loki and a rather feisty valkyrie. The game has been spinning since 2010, yet it still holds up remarkably well, largely thanks to the four distinct bonus modes hiding behind that hammer.

As always, our main focus here is RTP, but before we dive in, take a look at which casinos currently offer the best average payback across the board:

The RTP on Thunderstruck II tops out at 96.65 percent, a genuinely solid figure considering there is not even a bonus buy option that operators could use to shave it down. Volatility sits at medium, so expect a fair mix of smaller base game wins alongside the occasional proper jolt once the bonus kicks in.

The Great Hall of Spins

Land three or more Mjolnir scatters and you unlock The Great Hall of Spins, where you get to pick one of four gods to spin with:

Valkyrie hands you 10 free spins with every win multiplied by 5x, simple and effective.

Loki brings 15 free spins featuring Wild Magic, which randomly turns regular symbols into extra wilds. Sneaky, and genuinely fun to watch.

Odin grants 20 free spins where the ravens Hugin and Munin can trigger 2x or 3x multipliers, sometimes stacking up to 6x when both show up together.

Thor rounds it off with 25 free spins and Rolling Reels, where the multiplier climbs all the way to 5x as wins keep tumbling in.

On top of the bonus round, the Wildstorm feature can strike randomly during base play. Up to five reels turn fully wild on a single spin, and this is honestly how most players ever reach the maximum win of roughly 8,100x the stake.

Paylines and bet levels

Thunderstruck II runs on 243 ways to win across its 5 reels and 3 rows, so there are no fixed paylines to juggle. Bets typically range from around CA$0.30 up to CA$15 per spin, and maxing that out puts the theoretical top prize somewhere north of CA$120,000.

Symbols and paytable

The wild is the game's own logo symbol, it substitutes for every regular symbol and doubles any win it helps create.

The regular card symbols (9 through A) pay noticeably less than the gods, which is fairly standard for this style of slot. Landing five Mjolnir scatters also pays out 200x the stake on top of triggering the bonus, so scatters are worth celebrating here too.

Game studio

Microgaming is the studio behind Thunderstruck II and the game played a big role in cementing its reputation as one of the industry's most respected names. Extra care clearly went into the visuals and soundtrack when building the sequel, and it still shows all these years later.
