Thunderstruck II

Thunderstruck II is the follow-up to Microgaming's epic Thunderstruck slot. Although it might be hard for fans of the original slot to imagine that its sequel can improve on what's admittedly one of the most popular online slots in history, if you've yet try it, we're sure that you'll be pleasantly surprised by what Thunderstruck II holds in store.

To start with, you have 243 paylines with which to create winning combos, and then, there's a feast of special features including the Great Hall of Spins where you can benefit from Rolling Reels, win multipliers, Wild Magic, and Wild Raven Features. And, there's one final feature that'll leave you quaking in awe of the Norse gods' power – Wildstorm – where the reels are struck by lightning, causing up to five reels to become completely wild. This fantastic fantasy-themed slot is available to play on your desktop or mobile at Samba Slots for as little as 30p.

More about the Software Provider

Microgaming has been on the scene since 1994 when it launched the world's first real online casino. Over two decades later, and it's still a major industry player that powers hundreds of online bingo, poker, and casino sites. As of 2017, Microgaming has created close to five hundred slots, which range from progressive jackpot slots like Mega Moolah, King Cashalot, Major Millions, Tunzamunni, and Treasure Nile to video slots such as Avalon II, Bar Bar Black Sheep, and Game of Thrones.

Appearance and Sound Effects

Dreamy orchestral music that changes from hauntingly beautiful to surging and powerful and back again begins the roller-coaster ride experience that comes with playing Thunderstruck II. Rumbles of thunder indicate the presence of some of the most famous Norse gods, including Thor, Loki, Valkyrie, and Odin, who are used as paytable symbols. These imposing deities stand shoulder to shoulder with longships, Valhalla, Thor's hammer, the game logo, and six playing card symbols.

You can form wins from left to right using adjacent symbols combinations, which gives you no less than two hundred and forty-three ways to win.

Bonuses and Special Features

The Thunderstruck II logo which sits in front of an enormous bolt of lightning is the wild symbol, and it not only doubles the value of all wins it creates, but it also replaces any symbol except the scatter to help create wins.

Although the rock band, Queen sang "Thunder and lightning – very, very frightening", you'll be dying for rumbles of thunder and forks of lightning to start crashing onto your screen as they signify the arrival of the Wildstorm Feature. Wildstorm can strike at random turning one, two, three, four, or all five reels wild for the duration of one spin.

Entry to The Great Hall of Spins is gained by landing three, four or five of Thor's bonus hammer symbols across the reels. To begin with, you can only choose one of the four free spins features, but as you continue to trigger the bonus while playing Thunderstruck II, the remaining characters start to become unlocked. Even better, if you always play Thunderstruck II at Samba Slots, the game remembers your progress so far, so that you needn't start from scratch each time you log-in.

The beautiful goddess, Valkyrie gives you ten free games with a five times multiplier on all wins, and you can retrigger her feature with another three, four or five bonus symbols.
The elfin-eared, Loki who was the trickster god in Norse mythology, awards fifteen free games. During Loki's bonus, the Wild Magic symbol can appear on Reel 3 where it can randomly turn symbols into additional wilds. You can also earn extra free spins with two or more Hammer symbols.

Odin, the Kind of the Aesir and God of Death and War, rewards you with twenty free spins. In the Odin Free Spins Feature, the war god's ravens can turn random symbols into x2 and x3 multipliers.

The last character you can unlock in the bonus is Thor, the god of thunder and the inspiration behind Microgaming's Thunderstruck II slot. He grants you twenty-five free spins with the Rolling Reels Feature. Rolling Reels allows you to create back-to-back wins by removing winning symbols from the reels and letting new ones replace them. With each consecutive win, the multiplier increases by one up to a maximum of x5.


Thunderstruck II uses five reels, three rows of symbols, and 243 paylines, and has a high RTP (Return to Player Rate) of 96.652%.
