Thunderstruck 2 Slot Machine Overview

Combined with 243 ways over five reels and multiple features, the Thunderstruck 2 slot machine seems to deliver promising winning potential. While the base game provides interesting benefits, the free spins offer incredible opportunities.

Inspired by Norse mythology and focused on the God of Thunder, you join Thor and other Norse gods in Asgard. Despite being released in mid-2010, the new December 2020 version ensures Thunderstruck II offers a modernized layout, enhanced animations, and sound effects that compete with some of the latest releases.

First released by Microgaming and now available on the Games Global platform, Thunderstruck 2 remains one of the best real money slots. The combination of different bonus features keeps players returning for more, whether for fun in the Thunderstruck 2 gratis demo version or big payouts in the real-money version.

How to Play Thunderstruck 2 Online

To play Thunderstruck 2 online, simply register with one of the recommended real money online casinos, make a deposit, and search for the game. Once it’s loaded on your screen, follow these easy steps to start playing.

  • Review payouts and features: Before you spin the reels for the first time, click on the burger menu and choose the pay table to review the payouts, game mechanics, and features.
  • Choose your bet per spin: The stack of coins button activates the betting menu, which represents the total bet per spin. You can choose from set amounts under “quick bets” or use the slider to find the perfect amount.
  • Set the reels in motion: The spin button is located in the middle, which would deduct the betting amount from your account balance. Should three or more of the same symbols line up from left to right in any direction – thanks to 243 ways to win -, you’ll activate winnings according to the pay table.
  • Use turbo spins and autoplay: The rotating symbol opens the autoplay options, allowing the reels to spin automatically based on your set betting value and other settings. You can also increase the spinning speed by pressing on the lightning bolt

Thunderstruck II Bonus Rounds

The Thunderstruck II slot game offers a wealth of different bonus features. These include rolling reels, transforming symbols, multipliers, and random wild reels.

The highlight is the four-tier free spins bonus available in the Great Hall of Spins, each based on one of the mythological characters. The number of spins and additional chances of winning vary for each free spins bonus feature.

The Great Hall of Spins

Once you gather enough Thor hammer scatters to enter the Great Hall of Spins, it is almost as if the four Norse gods compete for your favor. Instead of being given a choice, you can access various free spin features after activating the bonus round several times. Every five sequential triggers unlock a bonus game.

Raymond van WykGambling Editor

“If you're a fan of high-paying free spin features, the Thunderstruck 2 slot should be among the top of your favourites. Unlocking all the options takes some time, but as more features become available, you'll notice it's well worth the wait. The slot will keep your progress, which means you can close the game and come back to continue where you left off later.”

Valkyrie Free Spins

The Valkyrie free spins feature is available from the first trigger and grants ten free spins. All wins during the bonus benefit from a 5x multiplier. It is possible to retrigger, and additional spins get added to the remaining free spins.

Loki Free Spins

The Loki free spins feature activates on the fifth trigger and awards 15 free spins. These free spins include the wild magic symbols that appear on the third reel and can transform up to fifteen symbols into wilds. If two, three, four, or five scatters appear, you win 1, 2, 3, or 4 extra spins.

Odin Free Spins

Available from the tenth trigger, Oden gives you 20 free spins, and the wild raven bonus feature activates with any win. Random symbols turn into wilds with multiplier values up to 6x. Retriggering this free spins bonus round is not possible.

Thor Free Spins

The Thor free spins feature becomes available when you activate the Great Hall of Spins for the 15th time. You gain 25 free spins boosted by the rolling reels feature. Activated by any win – apart from scatters that trigger the bonus – winning symbols disappear, and the symbols from above fill the empty spaces, which opens up more chances of combination wins.

During the rolling reels, the multiplier increases by 1x up to 5x, and retriggering is impossible.

Thunderous Wildstorm Feature

Thor uses lightning bolts to transform up to five reels into wild reels once the wildstorm feature activates randomly during the base game. While no wild symbols or scatters will show up, and you can’t trigger the free spins feature, if all five reels turn wild, you win 8,000 times your total bet.

Special Symbols

Thunderstruck Wilds: The wild symbol substitutes for other symbols except the scatter to complete wins and double payouts. It does not appear during the wildstorm feature.

Bonus Scatter: Three, four, or five Mjolnir scatter symbols trigger the Great Hall of Spins features and award payouts of 1, 2, 20, or 200x your total stake.

Thunderstruck II Slot Review

Combining eight bonus features is the main reason for the Thunderstruck 2 slot’s continued popularity. In addition, it offers a maximum win of 8,000x and an above-average RTP.

Few online slots can compete with the four-tier free spins bonus feature, which certainly stands out as the highlight in the Thunderstruck II slot. However, with higher volatility, those high-paying features and combinations could take some time to activate.

Thunderstruck II Slot Review of RTP and Volatility

The RTP of 96.65% is above the average return percentage of 94% to 96% and closer to 97%, categorized as one of the high RTP online slots. The high volatility means payouts can take longer to activate but deposit higher winnings.

The largest payouts in the Thunderstruck II slot come from the wildstorm and the free spins features, although activation can be infrequent.

Our Top 3 Reasons to Play Thunderstruck 2 Online

It all comes down to personal preferences, and Thunderstruck 2 online slot’s combination of features caters to them all.

  1. The Thunderstruck wild symbols often appear to award doubled five-of-a-kind wins while assisting during the free spins to gain payouts, multiplied by 5x.
  2. The wildstorm feature is a high-paying addition that increases the number of ways to claim the maximum win.
  3. The free spins bonus feature adds an exciting gamification or leveling-up factor that rewards you with chances of more significant rewards for the number of times you activate the bonus and frequent play.

Similar Games to Thunderstruck 2 Slots

If our review of Thunderstruck II piqued your interest, we’ve included three other games you might want to try in demo mode.

    • Gonzo’s Quest – A 20-payline adventure awaits in Gonzo’s Quest featuring avalanche reels and free falls leading to wins of up to 37,500x.
    • Sugar Rush: The high volatility in Sugar Rush leads to loads of free spins, multipliers up to 128x, and sweet wins up to 5,000x.
    • Gates of Olympus: Unlock the gates to heaps of bonus thrills, including free spins and multipliers that lead to payouts up to 5,000x.

    Thunderstruck 2 Slot Review – Our Final Verdict

    Often referred to as one of the most loved slots, it offers equal parts profit and fun. Throw in how bonus features get earned, and it makes sense that its shelf life keeps it among the most popular. The tremendous winning potential in the wildstorm can strike in any spin, which ensures the base game remains exciting.

    It paved the way for other favorites, such as Thunderstruck Wild Lightning and Thunderstruck Stormchaser. Thunderstruck II is also the motivator behind the free spins bonus structure in the highly favored Immortal Romance slot and its sequel soon-to-be-released.

    Its success led to the release of the Thunderstruck 2 deluxe version. Thunderstruck 2 Mega Moolah links to the overwhelmingly popular Mega Moolah progressive mini, minor jackpots.
