Thunderstruck II Slot

People often (and incorrectly) say that lightning never strikes twice, but they never make the same claim about thunder. Thunderstruck has already been a smash-hit online slots attraction for Microgaming once, and so it's no surprise that they brought it back for a sequel where there's even more to play for. It's one of the most popular creations within the increasingly popular Norse genre of online slots, and you're about to find out why. One thing Microgaming can't be accused of is failing to take its subject matter seriously. While there are splashes of colour here and there, the five reels and three rows of the Thunderstruck II slot are all-business, with serious-looking character faces staring back at you from the stony blue reels. The full raft of playing cards from 9 to A are of little value as symbols, but you'll get more from Viking longships, Asgard, Valkyrie, Odin, Loki, and Thor. Bonus points if you recognise all of those names without having seen any of the associated Marvel movies. The Thunderstruck II slot has a wild symbol in the shape of the slot’s logo, and Thor’s hammer to act as a scatter.

Additional Wilds

: This is a randomly-generated reel modifier. On or before any spin, the gods may decide to bless you with between one and five stacked wild reels. This is known as a “Wildstorm,” and it’s always a welcome sight.

Free Spins

A slot that boasts so many gods should be able to conjure up a better free spins feature than your average slot, and Thunderstruck II does. In fact, the longer you play, the better it gets. Here's how it works. For the first four times you trigger the free spins feature (three Thor’s hammer symbols do the trick), you get Valkyrie’s free spins. That’s ten spins with an x5 multiplier in place. Trigger free spins between five and ten times for Loki’s free spins, of which there are fifteen. A new “magic” symbol is added to the reels and generates multiple additional wilds. Stick around for ten free spins rounds to get Odin's free spins. Now you have twenty spins and a randomly appearing raven, which creates multiplier symbols wherever it lands. If you've been playing for long enough to trigger free spins fifteen times, we have two pieces of information. One, you should probably grab a snack. Two, you're now playing Thor's free spins. He offers 25 spins, and an avalanche pays system that boosts the multiplier by x1 each time you win anything.

About Microgaming

Most companies involved in developing online slots are still in the nursery compared to Microgaming. They’ve been around since 1994. That’s long enough for the entire industry to change around them, so you could say they’ve seen it all. If you ask them, they’ll tell you they made it possible for you to be here at Rose Slots today. It was Microgaming that launched the world’s first-ever digital casino software platform in the 1990s. They also claim to have released the first mobile casino software in 2004. They’re a company of firsts. Counting all of Microgaming's successful online slots would keep us here all day, but suffice to say they've got some classics in their back catalogue. Immortal Romance, Avalon, and Bar Bar Black Sheep all stand as testimony to that. Both Thunderstruck slots belong to that same lineage of greatness. As if all that weren't enough, they also offer the biggest progressive jackpot in the world via their Mega Moolah slot!
