Thunderstruck II – The Essentials

✰ Microgaming is the real deal when it comes to producing great video slots. They were one of the early online slots pioneers and this is one of its masterpieces.
✰ This game has five reels and 243 ways to win. This huge number of ways to create winning combinations is a clue into why players love this slot.
✰ The theme has a vibrant colour scheme. It will transport you back to the ancient times of the Vikings.
✰ Spins start at £0.30, and if you’re a high roller you can bet as much as £15 per spin. That makes the maximum spin affordable for many, which is another reason for the enduring appeal of this game.

Thunderstruck II Slot Features

This slot has one main bonus round and a base game feature which can create some colossal wins.

☑ Wildstorm – This is a base game feature which is activated totally randomly. When it occurs up to five reels can turn totally wild. Any experienced slots player will know this is a big deal and can create spectacular wins.

☑ Hall of Spins – This is a free spins bonus round with multiple levels. The more times you trigger it, the more you can potentially win. The first time you will get 10 free spins with a x5 multiplier, but by the 15th time you will get 25 free spins, winning symbols will vanish and be replaced by new ones, and a multiplier which grows with each win will help boost wins.

How to Play

  1. Set the number of coins you want to bet. This can be between one and ten. The more coins you bet, the bigger your bet sizes and potential wins.
  2. Set the coin value from between 0.01 and 0.25. Again, the higher the value, the greater the risk/reward ratio.
  3. Finally, click the blue spin button in the bottom right. This will place your first real money bet.


If you’re feeling gutsy you can click the “bet max” button. Don’t play around with this because as soon as you click it the spin occurs.

Thunderstruck II Slot Tips

No two slots are the same. Thunderstruck II is unique and should be played as follows:

Be ready for the Wildstorm feature. This can create multiple wins at the same time and your bet size will determine how much you win.

This slot requires patience to reach the most valuable wins available in the Hall of Spins feature. Take your time and preserve your bankroll until you trigger it multiple times, at least, then increase your bet amounts.


New casinoThunderstruck II isn’t one to play for a massive jackpot, but rather one to play for the exciting features which can produce the biggest wins. The Hall of Spins round is the main attraction and as the “how to play” section above outlines, it pays to be patient.
