The Thunderstruck casino game by Microgaming is a 5 reel, 9 payline online video pokie that gives players a wide variety of coin sizes to choose from – 0.01, 0.02, 0.05, 0.10, 0.20, 0.25, 0.50, $1.00, $2.00. Players can choose to play between 1 – 5 coins per line, meaning the max bet ranges in size from 0.45 – $90, with a minimum bet of 0.01. All wins pay left to right, and are multiples of the line bet (scatter wins are multiplied by the total bet).

Jackpots

The biggest jackpot on offer on the Thunderstruck slots game is $300,000. This is won by hitting 5x Thor symbols during the free spins bonus feature when betting the maximum (the Thunderstruck free spins bonus round is activated by hitting 3x, 4x or 5x scatter symbols).

During base play, the biggest win on offer is $100,000, again for hitting 5x Thor symbols when betting the maximum coin size and number on all nine paylines.

Overall, Thunderstruck is a medium- to high-volatility game where there are a number of high payouts on offer and with an average RTP of 96.1%.

Special Features and Bonuses

The Thunderstruck free spins bonus is triggered by hitting 3x, 4x, or 5x scatter symbols anywhere on the reels. During this bonus feature, all wins are multiplied 3x, meaning the maximum jackpot that can be won during this round is 150,000 coins ($300,000) for hitting 5x Thor symbols when betting the maximum coin size, number and paylines.

The gamble feature gives players a chance to increase the payout of any winning spin. If you opt to gamble, you are taken to a separate screen where you are presented with a playing card. In order to win, you need to predict either the colour or the suit of the card – if you opt for the colour and are correct, your win is multiplied 2x; if you correctly predict the suit, your win is multiplied 4x. In either case, if your prediction is wrong, you lose the sum you gained from your winning spin. You can gamble any win up to four times.

Thunderstruck also has auto play and quick spin features.

Graphics and Sounds

The way the Norse mythology theme is presented in the Thunderstruck slot is one of the reasons for the game’s ongoing popularity. The graphic-novel style of the images is highly effective, with symbols including the God Thor, a battle-axe, lightning bolts, a ram’s heads and a castle, while the bright colours and animation of the symbols make the game highly engaging visually. The soundtrack as the reels spin features a menacing drumbeat reminiscent of horses’ hooves, and this adds significantly to the drama, as do the bursts of trumpet music on winning spins and the thunderclaps when two or more scatter symbols are hit.

Conclusion

Although it has inspired a very successful sequel (Thunderstruck 2, released in 2010), the original version of the game still remains popular. This is due to a combination of the theme (medieval subjects are always popular subject matter for online pokies) and the relatively straightforward gameplay that nevertheless offers some very substantial payouts. The Thunderstruck free spins bonus feature, where all wins are tripled, is particularly lucrative and the main highlight when playing the game.
