Thunderstruck is a slot game published by Microgaming, now known as Games Global, that centres around Thor, the Norse god of thunder and storms. In this Thunderstruck slot review, we will give you all the details of this game with 5 reels and 9 paylines. It was released in October 2003 and is still quite popular with its relatively high potential max win of 30,000x your bet.
Thunderstruck is a really old game, having been released in 2003. This means that it does not have the many game mechanics that we are used to seeing in more contemporary slot games. In fact, this slot features 5 reels, 3 rows and 9 fixed paylines. As with most traditional slot games, a winning combination is formed by getting three to five matching symbols across a payline starting from the first reel. However, in Thunderstruck it is also possible to get a win by getting two matches of the two higher value symbols.
The betting stakes range from You can wager $0.09 to $45 per spin. This is quite a low wager range making it convenient with players who want to keep a close eye on their bankroll. The game's RTP is 96.1%, which is decent for such an old game. Its variance is average; most big wins will be during the bonus features. The potential maximum win is 30,000x your bet per free spin. You can only unlock this maximum win by playing the Free Spins feature.
There are many online slot casinos to play this iconic slot game. Due to a large number of options, we have compiled below a list of the best ones.
This slot game has a Viking / Norse theme, with a stormy sky in the background. It plays into the fact that the game is based on Thor, the god of thunder. The symbols are also themed around Norse mythology and Thor-related concepts. Due to it being an old game, the overall graphics can feel quite dated. Still, it is not bad for its age, and this may be endearing to some players.
The highest-paying symbols are the symbol of Thor's staff and hammer. These symbols will give you from 0.33x up to 83.33x your bet on a single payline, resulting in a total of 750x if you get 5 across all paylines. Other symbols include the Cornucopia, lightning bolts, castles, and the A, K, Q, K, 10, and 9 royals.
The wild symbol is Thor himself. Getting Thor symbols can get you up to 1,111.11x your bet per payline, which means a full screen can get you 10,000x your stake. It replaces all symbols except the ram scatter symbol.

At its initial release, this game had no option for players to play on mobile. After all, it was released in 2003, and technology was not as advanced yet. However, Microgaming worked on the game by revamping it with HTML5. You can now play the game on your desktop, mobile, or tablet device. It is accessible on almost any gadget. Its 5 reels and 3 rows layout also makes it very friendly for small screens.
This slot game comes with two bonus features, which we will discuss in more detail below. The first feature is the Double Wild feature, while the second is the Free Spins feature. Among the two, the Free Spins feature offers more in terms of how much you can win.
This feature relates to the Thor wild symbol's function in the game. Aside from being able to substitute for any symbol to help create winning combinations, it has another function. The Thor wild symbol also doubles any win it helps create. For example, it can double your Thor's hammer full-screen win of 750x to 1500x if it is part of the winning combination.
The most exciting feature in the game is the Free Spins feature. The feature gets triggered if you get 3+ Ram scatter symbols anywhere on your reels. Upon getting triggered, the feature gives you 15 free spins and a 3x multiplier to your wins during the free spins. You can also trigger it repeatedly to keep getting 15 free spins, but the 3x multiplier stays constant. It is possible to activate the Double Win feature and Free Spins feature at the same time. Getting a win with the Thor wild involved on the Free Spins essentially subjects you to a 6x multiplier.
However, note that if you get a full screen of Thor Wilds in a Free Spins feature (10,000x your bet), you will only get the 3x multiplier. It results in a win of 30,000x your bet, which is the highest possible win in the game.
With the game being out since 2003, it's pretty hard to track down the biggest win in history in the game. However, we can easily calculate what the highest possible win is.
The maximum multiplier you can get is 30,000x your bet, and the maximum wager per spin is $45. Thus, it's pretty easy to calculate that the highest win you can get on a single spin in the game is $1,350,000.
However, this is far from the accumulated total of what you can win from the game. If you like to play a lot and bet a lot, you can win more.
Thunderstruck is an iconic slot game in the industry among slot players. Its dated graphics still appeal to many players, and its revamped version now gives players access to it on mobile. It is one of Microgaming’s most well-known games. Due to its wager range, the game tends to have smaller, constant wins rather than few but colossal max wins. It is friendly for low-budget betters and constant betters alike. Its bonus features also offer great win opportunities for the player. This slot is so popular Microgaming released Thunderstruck II in 2010 with improved graphics, better game mechanics, and a higher potential max win.
Overall, Thunderstruck is a classic slot game with decent win rates, win multipliers, but it is dated and it probably makes more sense to play newer slots. Overall, I would rate it an 8 because it is one of Microgaming's most recognizable products and will likely remain that way for a while.
