Game Review

Thunderstruck Slot

Thunderstruck is a Norse mythology-themed online slot game made by the oldest online casino studio in the world – Microgaming. The classic visuals, generic tunes and free spins feature to provide for a more traditional video slot entertainment experience. The game is an iconic masterpiece and is due an accolade or two.

Theme, Soundtrack and Symbols

Based on Thor, the god of thunder, this mythological Microgaming online slot takes place in the heavenly. The 2D classic graphics and arcade-like music and sounds feel like you are in a time warp, travelling back to the infancy of video slots. But do not be fooled! Thunderstruck is still able to strike up some great luck!

The reel symbols tell the full story and provide combinations to add money to the tale. The higher- paying symbols include thematic icons such as a battle horn, bolt of lightning, the Asgardian Castle Thruthvanger, Thor’s hand, and Thor’s hammer, called Mjolnir.

Even though the lower-valued icons are simple card deck symbols, they are befitting of the theme and are made of molten gold.

The game Wild is suitably Thor himself, who will substitute for all standard game symbols to complete winning paylines where he can. The scatter is key to triggering the main feature.

Game Mechanics

Thunderstruck is played over 5 reels with only 9 paylines. All wins are registered if 3 matching symbols land on a set payline from the left-most reel to the right.

The low to medium game variance ensures that you won’t have to waste too much time before you land some wins. These rewards are not too bad, especially when you take into account the fact that the jackpot payout is 10,000x your line bet.

Begin playing from 0.09 to 45 coins on the wager lines and hit the Spin button to try for the win.

Special Features

This game harks back to the good old days when one main feature and a Gamble feature were sufficient for top-notch slot nobility.

Free Spins Round

This feature is triggered by landing 3 or more scatter symbols on the reels. The reels then pump with adrenaline to spin 15 super-fast rolls that come with a 3x multiplier on all wins produced in the game.

Gamble Feature

The Gamble feature can be activated after any winning combination. Here, you will be given the opportunity to double your win to increase your bankroll.

Simply hit the ‘Gamble’ button and play a game where you will need to choose the colour of the next card to be selected from the card deck (red or black). There is a 50% chance of winning. Select correctly, and you will double your win. You will then be given a chance to collect the win and add it to your bankroll or play again to attempt double the new amount.

At any time in the game, if you get a colour selection wrong, you will lose all the money applied to the Gamble feature. We, therefore, advise that you only use this function sparingly to boost the small win amounts, rather than risk big money in this volatile pick game.

Play ‘On The Go’

Thanks to Microgaming’s Quickfire platform, this top slot has been able to transition to the mobile arena without too much fuss. The game is playable in its full glory on the small screen from your Android or iOS mobile device, courtesy of the latest in HTML5 technology. The features all remain intact, and the visuals remain the same as the online game as well.

Only the game controls are simplified for touch screen playability.

CasinoWow Game Verdict

To rate Thunderstruck, we need to look past the dated graphics and simple features and see this classic video slot for what it is. It is an iconic piece of gaming that helped set a precedent for many of the more modern Microgaming ensembles.

Thunderstruck II is a later more updated instalment, yet traditional slot players will often choose the original over the sequel, every time.
