Thunderstruck Symbols And Payouts

The slot remains true to the original 2004 version with a grid of 5×3. Thor’s hammer may be mighty but the paylines are not, coming in at only nine. You’ll need to find winning combinations from left to right.


Thunderstruck rocks the skies with the standard playing card images between Ace and Nine, giving you six symbols with the lowest values. The higher-paying ones represent the Norse lore surrounding Thor.

They consist of:

  • the hammer Mjölnir
  • battle horn
  • Thor clutching his mighty weapon
  • lightning 
  • Thor’s home in Asgard


For our Thunderstruck review, we discovered that Thor pays the highest as the substituting wild, with a winning of x10,000. Here’s what the paytable looks like in the game.

TS 1

Thunderstruck Min / Max Bets

Despite Thor’s massive legacy, this slot has a low betting range. The limits are between $0.10 and $100.

This low minimum makes it a top game for players on a budget. 

Thunderstruck RTP, Volatility & Hit Frequency

Thunderstruck has an RTP of 96.05%, which is comparatively low. Not surprisingly, the game has high volatility, so wins tend to be less frequent and large.

The bonus has an extremely low hit frequency, but you’ll see the coins falling from the thunderous heavens when you win big.

Thunderstruck Jackpot and Maximum Win

Digital Gaming Corporation’s updated Thunderstruck doesn’t appear to feature any progressive or fixed jackpots. However it does have a maximum win of x10,000. That’s $100,000 on a $100 bet!

With only nine paylines available, you’ll wait a long time during the free spins mode to receive five Thors.

Thunderstruck Features

You won’t find that many unusual features in Thunderstruck. If you like a more classic slot, then this lack of options can let you focus on the reels.

It mostly consists of wilds, a gamble feature, and free spins.

Wilds, Respins, and Other Base Game Features

The base game holds the singular wild and the gamble feature. You won’t see any re-spins or bonus activities.


Thor is the wild in the casino slot, paying the maximum payout for five matches. It replaces any other symbol besides the scatter, ensuring that you have a better chance at receiving winnings across its nine paylines.

There are no other wild features.


Gamble Feature

For every win in the base game or bonus round, you’ll see Mjölnir appear to decide if you’re worthy of multiplying your winnings.

Choosing the right card color doubles it, while the correct suit quadruples it.

Your bankroll’s fate lies in your hands.

Thunderstruck Free Spins

You may have noticed a pair of scatter rams on the paytable. Receiving at least three of them can give you up to three spins.

For further enticement, the game triples all your winnings from the bonus round.

Graphics & Sound

The revised graphics by the Digital Gaming Corporation looks better than the original version. However, it has the same Norse theme and images, simply with improved resolution.

The bonus wins animations are exhilarating, though, and you’ll have no doubt that you won. You’ll hear the sounds of thunder for sure, but it’ll be the lightning that strikes now and again.

The effects are improved, while the background music is enjoyable. Overall, the graphics and sound are not overwhelming (for better or worse).

Other Slots To Play If You Like Thunderstruck Slot

If you like old slots from the original creator of Thunderstruck, give Microgaming’s 2004 Tomb Raider a go. Showcasing themes from the first video game, it has an RTP of 95.22%. There’s a temple with totems and special free spin features.

Microgaming followed the above game with Tomb Raider: Secret of the Sword in 2008. With a similar RTP at 95.23%, it brought extra bonus levels to the series. Some of them include substitutions, multipliers, and bonus games.

Returning to Norse mythology, we have Red Tiger’s 2019 title Thor’s Lightning. The volatility is slightly better at medium-high, but the RTP is 95.1%. However, with avalanching reels and free spins, the RTP range changes for each spin depending on the outcome.

There’s nothing better than an almighty clash between different mythological deities. Perhaps inspired by the video game God of War’s transition from Greek to Norse lore, 2 Gods: Zeus vs Thor is a 2020 title by 4The Player. It has an impressive 96.5% RTP with high volatility.

You might also check out CQ9Gaming’s 2018 God of War slot. No, you won’t find Kratos in the game. Instead, you’ll discover an unknown warrior slashing his way through 243 paylines. It has a Japanese samurai theme with substitution and scatter symbols.

Thunderstruck Review – Conclusion

Thunderstruck might be an unusual name, but it delivers in terms of gameplay and a low betting range.

The graphics are updated from the 2004 original, but most of the features remain the same.
