Thunderstruck II


Nowadays there are many video slots based on various gods from mythologies. Back in 2004, Microgaming released an online slot by the name Thunderstruck, and you can probably guess the game is based on one of the most recognizable gods, Thor. Thor always seems to be the right choice when going for a powerful mythological being, mostly because of his good looks and mighty hammer.

Like many of Microgaming’s video slots, Thunderstruck has 5 reels, 3 rows and 243 ways to win, which will make for ample action and a powerful gameplay. Considering the game was released in 2004, it has fairly decent visuals that still hold up with today’s slots. While you cannot expect high-quality 3D animations that other video slots feature aplenty, Thunderstruck still manages to entertain with its cartoonish graphics and decent sound effects.

Gameplay & Features

The game features a hunting horn, bolt of lightning, the castle of Thruthvanger, Thor’s hand and his magical hammer as high-paying symbols. It also features Thor himself as the Wild symbol, which will substitute for all other symbols but the pair of rams, which is the Scatter symbol.

If you manage to land the Thor Wild symbol, his hair will wave through the air blown by the wind due to the animation. He will also multiply each of your wins with a 2x multiplier if he is part of the winning combination.

Thunderstruck will you give a go at the Free spins bonus feature if you can land 3 or more Ram Scatter symbols. You will receive 15 free spins, but each win during this bonus round will be amplified by a 3x multiplier. You can additionally get 15 more free spins if you land 3 or more Rams during this round. The Scatter symbol will award you even before you enter the free spins bonus round, as Scatter wins are multiplied by the total number of your bet.

Playing Tips

This game offers many great features. This includes the possibility to choose to play the game in expert mode. When you click ‘Autoplay’, the games gives the player multiple options. You can set all the parameters for the autoplay yourself and watch the gameplay unfold. Make sure to set that you play the gamble feature yourself and not leave it to autoplay to make your decisions.

The gamble feature is also available during the base game. Like in most gamble features, you have to guess the correct colour of the card to double your most recent wins. If you guess the correct card suit, you can easily quadruple your wins.


Unlike most online slots today, Thor does not heavily rely on its graphics to entertain the player. Instead, it features thrilling bonus features and charming visuals that remind you more of 90s video games than of advanced video slots. But still, the graphics are decent and make this game a journey back in time. Other than maybe the graphics, which became immensely better with its successor Thunderstruck II, we don’t really see any disadvantages in this game.

Our Take

This game is colourful, entertaining and fast, and comes with a nice amount of bonus features, that were more than enough back in 2004. If you enjoy slots that stood the test of time, check it out.
