Thunderstruck II Slot: Where gods and winnings collide!
First things first, this slot is all about Norse mythology. We're talking Thor, Odin, Loki and the Valkyries - the whole godly gang is here. If you're into Viking legends (or just like the Marvel version of Thor), you'll love the way this game brings the mythology to life. The design has a kind of mystical, stormy, blue-grey aesthetic that makes you feel like you're in Asgard, right in the middle of an epic battle.
Compared to the first Thunderstruck slot, this sequel amps everything up. The graphics are sharper, the soundtrack is more dramatic and the gameplay is packed with more bonus features. It also introduces the Great Hall of Spins, which is basically a multi-level Free Spins feature that gets better the more you trigger it.
In short, Thunderstruck II isn't just another slot by Microgaming - it's one of those games that has stood the test of time and is still a fan favourite after more than a decade. And that's saying something.
How to play Thunderstruck II
Thunderstruck II is a 5 reel, 3 row slot machine with 243 ways to win. This means there are no fixed paylines - you win by landing matching symbols from left to right on the adjacent reels.
Here's the basic breakdown of how it works:
- Bet sizes range from $0.30 to $60 per spin, so it's good for casual players and high rollers alike.
- Winnings are calculated by multiplying your bet per spin by the payout for any combination you land.
- The Thunderstruck II logo is the Wild, meaning it substitutes for all normal symbols to help you land winning combos.
- Mjölnir (Thor's hammer) is the Scatter, and you'll want to see it as it unlocks the big bonus features.
It's easy enough to pick up, but there's a lot of depth thanks to the bonuses (which we'll get to in a moment). The biggest takeaway? 243 ways to win is always fun because there's no need to worry about paylines - just land matching symbols and you're good to go.

Paytable: What the symbols are worth
Thunderstruck II has a mix of high paying character symbols and lower value card symbols. Here's a breakdown:
High paying symbols (These are the ones you REALLY want to see)
- Thor - The God of Thunder himself. Getting 5 of him pays big.
- Odin - The All Father brings some solid mid-range payouts.
- Loki - The trickster god gives you a shot at some nice wins.
- Valkyrie - She's here to guide fallen warriors... and boost your bankroll.
- Asgard - The legendary city is also a high paying symbol.
Low paying symbols (Meh, but they keep the balance ticking over)
A, K, Q, J, 10 and 9 - These are the standard fillers.Special symbols
- Thunderstruck II Logo (Wild) - As well as substituting for other symbols, it doubles any win it's part of.
- Mjölnir (Scatter) - This is the key to unlocking the Great Hall of Spins.

Special features: Where the real thunder strikes
This is where Thunderstruck II really comes into its own. The special features in this game aren't just added extras - they're what make this slot legendary. It's not just about spinning the reels and hoping for a win; the bonuses give you several ways to rack up huge payouts, especially the Great Hall of Spins.
Let's break it all down:
The Great Hall of Spins - The core bonus feature
This is where the real money is made, and it's not just a one-off. The more you trigger it, the better the rewards. Every time you get three or more Mjölnir (Thor's Hammer) Scatters, you enter the Hall of Spins and unlock one of four Free Spins.
Here's how it works:
Valkyrie Free Spins
If you're new to the game, this is your first step into the Hall of Spins. The 5x multiplier is no joke - a single good spin can add up to some serious winnings.Available after immediately Free Spins 10 Feature 5x multiplier on all wins Loki Free Spins
This is where things get interesting. Loki's Wild Magic feature can turn a simple spin into a big payout, especially if several symbols turn wild at once.Available after 5th trigger Free Spins 15 Feature Wild Magic: A random Wild Magic symbol appears on reel 3 and can turn up to 15 other symbols into Wilds. Odin Free Spins
This is where the big wins come in. The ravens are a game changer, and with 20 free spins, you've got a good chance of landing some massive multipliers.Available after 10th trigger Free Spins 20 Feature Raven Feature: Odin's Ravens will randomly land on symbols and turn them into 2x or 3x Multiplier Wilds. If two ravens land on the same symbol, it becomes a 6x multiplier. Thor Free Spins
This is where Thunderstruck II reaches god-tier status. If you're lucky enough to get several wins in a row, your multiplier will continue to rise and by the time you get to your 5th+ win in a row, you'll be looking at some absolutely insane payouts.Available after 15th trigger Free Spins 25 Feature Rolling Reel: This is the best part - every time you get a win, the winning symbols disappear and new ones drop down (like a cascading win system). The multiplier increases after each consecutive win: - 1st win = 1x
- 2nd win = 2x
- 3rd win = 3x
- 4th win = 4x
- 5th+ win = 5x
Wild Storm Feature - A random, divine jackpot-like moment
If you're thinking "what if I don't trigger the free spins?" don't worry. There's another surprise waiting for you: the Wildstorm feature.
This is a randomly triggered bonus that can happen at any time during the base game. And when it does, things get wild - literally.
Here's how it works:
- Up to 5 reels can go completely Wild
- If all five reels go Wild, you hit the Jackpot and win the maximum payout.
This is a rare occurrence, but when it happens, it can be absolutely game-changing. Even getting 3 or 4 Wild reels can lead to some monstrous wins.
Wild Symbols - Double your winnings
- The Thunderstruck II logo is the Wild symbol in this game.
- It substitutes for any symbol (except the Scatter) to complete winning combos.
- And the best part? All wins with the Wild symbol are multiplied by 2.
This is a subtle but powerful feature. Even in the base game, just having the Wild in a win doubles your payout. And when it appears during Free Spins, things can get ridiculous fast.
Mjölnir Scatter - Your Key to the Hall of Spins
- Landing 3, 4 or 5 Thor's Hammer Scatters triggers the Great Hall of Spins.
- The more you trigger it, the more Free Spins features you unlock.
Scatters don't have to be on a payline - they can be anywhere on the reels. That's what makes them so exciting. Whenever you see 2 hammers land, you'll be holding your breath, hoping for the third.
Special features summary
This is what makes Thunderstruck II a legendary slot. It's not just about spinning the reels and hoping for a random win - it's about progression.
- The Great Hall of Spins evolves as you play.
- The Wildstorm feature can randomly drop a huge payout.
