Hello, once again, Viking enthusiasts. It’s me, your Viking guide, Bjorn To Be Wild. Back once again to murder another slot review and possibly you! Ha, just kidding, maybe.
The slot I will be discussing is a rather old one that came out in the year of 2004. A time when people of the world were normal, happy, and hadn’t set up expensive Airbnb businesses to fleece the rest of humanity.
The game is called Thunderstruck and was made by a company that no longer exists. Microgaming was once the ruler of online casinos, and then sold off its back catalogue of games, folded, and now lives as a hermit in the forests of some mystical land.
You can’t play the Thunderstruck slot anymore for real money, but it is available as a free slots demo game. Members of Casinos.com can access this game, and if the temptation to play a twenty-year-old slot doesn’t do it for you, then I don’t know what will.


Thunderstruck was a medium volatility slot machine that had a fairly consistent hit rate on wins. The RTP was also one of the highest at the time, with a rating of 96.1%. The rating highlighted the payback probability, which, being one of the highest, benefited both the player and the developer.
The maximum you could win was 3,333x the betting price you set per spin. The bet cost started at a minimum of $0.09 and rose to a maximum of $45 per spin. Therefore, if playing $45, you’d be in line to potentially win $149,985. Again, at the time, this was considered a big payout and pretty good value for money.
When you have set your bet, you can press the Spin button to start the game. The way to win is the same as it is now. Land three or more matching symbols on any of the 9 paylines and you collect a payout. Two or more of the Wild, Scatter, Hammer, and Handle symbols also resulted in a win.
The features within the Thunderstruck slot that was made by Microgaming.
Landing three or more scatter bonus symbols (two rams) would unlock the bonus game and earn fifteen free spins. The greatest part of all this is that all wins would be multiplied by x3. During the round, the free spins feature could be retriggered.
The Thunderstruck slot may have long departed the world of online casinos, but its success led to many sequels. You can still play these games for real money inside the best casinos online.
At Casinos.com, you can play each one of these games in the Thunderstruck series for free. Register now to play the original and all sequels to see and understand why this game and what followed it are significant slots in the history of casino gaming.
Leave a comment about your thoughts on the game, and it will likely remain there, never to be read by human eyes. I shall leave you now, as I have some remains of seamen to clear off the bow of my longboat.
