Thunderstruck II

Immerse yourself into Norse mythology as you are about to face Thor, Odin, Loki and Valkyrie on the slot from Microgaming. Released in 2010, the game has remained a huge player favourite up to the present day. In itself, it was the sequel to the 2003 original Thunderstruck slot in a 5×3 format with 9 lines. By the end of the decade, Microgaming had developed a 243-ways game engine and Thunderstruck 2 was the first to fully benefit from the vast possibilities it offered.

New-style free spins features with multipliers, random wilds or rolling reels, a random Wild Storm turning up to five reels wild and a top pay of 8,100 times the bet made Thunderstruck II an instant hit with players worldwide.

Slot Details

Thunderstruck II is a video slot with five reels, three rows and 243 ways to win. Pays are awarded for adjacent symbols from left to right only. Playable on desktop, mobile and tablet, it offers bet sizes from 0.30 to 15 credits per spin. Some casino operators such as 32RED offer bet sizes of up to 37.50 credits. The RTP of this medium variance game is set at 96.65%.

The design might not look totally modern among today’s creations, but in my opinion, it has aged well. Kept in Norse style, the game window features prominently the four gods – Valkyrie, Loki, Odin and Thor. The scenery changes in the free spins rounds to a setting associated with the respective god. A subdued heroic soundtrack goes into dramatic crescendos on winning spins.

Open the game to find the card royals from 9 to A at the low end, paying 3.33x to 5x your bet as standard and 6.66x to 10x your stake when in combination with a wild. They are followed by a Viking longship, a Valhalla rendering as well as the four Norse gods – Valkyrie, Loki, Odin and Thor. Pays for a 5OAK increase to 8.33 to 16.66x your stake as default, which is again doubled to 16.66 to 33.33x the bet when a wild is part of the winning combo.

The Thunderstruck II logo is the wild symbol, substituting for all regular pay symbols and doubling every win if part of the combo. Hitting five across the reels pays with 33.33x your stake the same as the top-paying Thor symbol. His mighty hammer marked with the word ‘Bonus’ is the scatter symbol. Two to five scatters will award coins wins from 1x to 200x your total bet.

The Random Wild Storm Feature

Watch out as heavy thundering and lightning can start at the beginning of any spin in the base game. Thor will drop with a loud thump from the top and start turning one to five reels wild. He will always start at the far left and move to the right. Wins are evaluated after the reels without an expanded wild have stopped. Getting a full screen of expanded wilds will pay the maximum win for Thunderstruck II which stands at a staggering 8,100 times your total bet.

The Thunderstruck II Free Spins Features

The second part of exhilarating moments on Thunderstruck 2 comes in the bonus rounds. A total of four are on offer in The Great Hall of Spins, each with its own characteristics. Valkyrie’s round is available as default while the other three need to be sequentially unlocked by triggering the bonus rounds a defined number of times. You can pick any of the rounds once you had 15 bonus rounds. To trigger the free spins, you will need to hit three to five scatters anywhere on the screen in a spin. The game will lead you to the feature selector screen, displaying the four options.

• Valkyrie Free Spins – available as default: You will get 10 free spins with an x5 win multiplier, which can be retriggered indefinitely. The most volatile choice as it can lead to both, super mega wins and very low pays alike.
• Loki Free Spins – available from the 5th trigger: You will get 15 free spins with magic wilds. Two to five scatter will add 1 to 4 extra free spins. The magic wild will turn a random number of symbols into wilds when it lands on reel three.
• Odin Free Spins – available from the 10th trigger: This round has 20 free spins which cannot be retriggered. Two ravens are sitting on top of the game window. Every time you hit a win, one or both will fly over the reels to turn a symbol into an x2 or x3 multiplier wild. The maximum multiplier is x6.
• Thor Free Spins – available from the 15th trigger: Thor will grant you 25 free spins with rolling reels and progressive multipliers. Any winning combination landing on a free spin will explode to let new symbols roll into place. The multiplier will start increasing after the first win to x2, x3, x4 and x5 with consecutive wins within one spin sequence. It will reset to x1 before the next free spin.

Final Verdict

Thunderstruck II is one of my all-time favourite slots, so this verdict might sound a little biased. The game is just so awesome and if you catch the Norse gods on a good day, you will walk away with huge wins. Of course, they can be stubborn as well and will eat sizeable balances with no mercy but most of the times the medium variance will get you long gaming sessions. It might look a little dated to some millennials who are used to fancy graphics, however, for me, it is the mother of all 243-ways slots.
