Thunderstruck Slot Review

    Thunderstruck is a 5-reel slot game developed by Yggdrasil that provides 9 possibilities of win. This video slot honours the God of Thunder, Thor, that is actually also the wild symbol of the game.

    Additionally, this slot machine does introduce more symbols like rams that are the scatters of the game, Thor’s hammer and also 9, 10, J, Q, K and A symbols. The user can play the demo version with no deposit or visit any of the online casino sites that own this slot machine in their list and get real money.

    Thunderstruck’s 3 ram symbols will offer the user a prize of 15 free spins where all wins are tripled. Thor, as a wild symbol of the game, will double the reward in a winning combination, making its value to be a 6x multiplier in free spins. That’s not all with what this slot surprises compared to other slot games. Thunderstruck has a unique feature for both desktop and mobile users named Gamble, where the user can grow the winnings. If the user predicts the color of the face down card right, the prize is doubled, but if the user guesses the suit that multiplies 4x the win. Although, it’s necessary to know how to play accurately and with good strategy, because wrong guesses will lead to the loss of the winnings. But the user can always stop this feature and save his/her accumulated prizes.

    Thunderstruck is recognized for its very low bet limits and high RTP value of 96,1%, making it the ideal and safe slot for users who don’t like to risk much, but want good winning returning chances. The minimal possible bet per spin is £0.09, and the maximal– £0.45.  It may be good for some players, but still a little bit hard for high rollers that desire to bet more.  Also compared to other slot sites, Thunderstruck does not possess a progressive jackpot, the highest achievable win being 270 000 coins of cash.

    This slot doesn’t have bonus games, but it has other options that will keep the user entertained during the whole game, such as:

    • The free spins round is triggered immediately after the player lands 3 or more Scatter symbols anyplace on the reels at the same time.
    • 3 of the ram symbols will offer the user with 15 free spins, where all accumulated rewards are multiplied by 3. Also, the free spins can be re-triggered for many times throughout the bonus round.
    • The Gamble feature is accessible not only in the base game, but also in the free spins round.

    How to Play

    Thunderstruck users can play with very low bet limits, the lowest being 0.09 and the highest 0,45 which is good for the users that don’t possess a huge amount of money to wager. Although that can stop the game excitement of the other users that want to play big in order to get big wins. But Thunderstruck gives significant cash awards, even by playing with minimal bets, that makes this slot one of the best online casinos on the market.

    Thunderstruck Slot Machine - How to Play

    • The user can begin to spin the reels after he/she has placed their bet level. It can be operated by hand by clicking on the spin button or the user can apply the auto spin option.  This will be active for a set of 5 to 20 spins, so that the user’s hands and mind can focus on other details and it is proved to bring more efficiency to the players.   Still, we recommend to spin the reels manually, if the user plays briefly.
    • Thunderstruck is a mid-variance slot, so that the user will need to high up his/her betting level in order to keep playing and get free spins, because that will offer the most wanted wins. From our experience, this happens mostly then we increase our wagering with more than 30x our bet, rarely by 100x and very rarely by 500x.


    Although this game is quite old-fashioned because of the basic graphic design and few bonus options, it has some powerful reasons why users should try it in 2020. Even if the 2004 slot machine cannot conquer the latest casino games in terms of sound and visual effects, the retro look of the slot still makes it charming and engaging.

    The slot machine is available not only on many online casinos sites, but also can be played on smartphones. Providers have developed a casino app, in which the user can download Thunderstruck and other slot games.

    The provided wild symbol and bonus games guarantee excitement and good winning possibilities. Another huge plus of this game is the high RTP value, which will certainly reward players with lots of wins in various proportions.

    This slot game has a medium- to high volatility. This denotes that the game owns some high awards, but they are inconstant so that the user can play for a longer time until a win combination shows up. But this slot has numerous smaller prizes that appear more often. In this way, the user can collect good cash amounts of money.
