Yes, this video slot is not rich on the various bonus functions, because it is still a representative of the classic category of the slot machines. However, it does not mean that you will be bored. One of the main attractions of Thunderstruck slot machine is its Wild (Thor) and the free bonus mode, in which you can win up to 15 free spins with a coefficient of 3x. The graphics, game mechanics and bonus modes Thunderstruck 2 video slot far surpass similar parameters of this slot machine. But, if you like old slot machines with drawn symbols and simple animations, then this will be really not a bad game. Moreover, it can be played not only on the desktop computers, but also on the mobile devices, both in free mode, and for the real money.

The slot machine is endowed with a medium dispersion. You will have as the serious victories and fall out the winnings of a small size. Be prepared for the fact that empty spins can happen the several times in a row, therefore it is worth taking care of that the account has funds for at least 200 rounds.

Symbols and payments:

The game is based on Norwegian mythology, so you will see on the reels of the legendary Thor, who owns his hammer, the purple coloured rams, Thor horns, lightning and the card symbols with a value from 9 to A. The latter are symbols of a low value, and thematic images bring winnings in the larger sizes. All elements are performed in a cartoon style.

  • PaytableThe minimum payment is offered to us by card symbols. So, for five dozen and nine, ladies and jacks, the payment will be up to 100 coins.
  • Five kings and aces will pay for 125 coins.
  • A full set of horn and lightning symbols will pay a winning of 250 coins.
  • For five symbols of the blue fortress, the player will receive a payment of 400 coins. The highest symbols in the game are Torah hammer and Hand holding the sword. For five of these images, the payment will be 750 coins.

In addition to the basic pictures at the video slot, there are also two special signs that will help you achieve the good results according to the results of the game session. It is a question of about scatter symbol and wild symbol.

Wild symbol. God of thunder Thor is your wild symbol, which not only appears on the screen frequently, but also replaces any sign except for the scatter, which will complete the most advantageous pay combination. Thor also acts as a multiplier, doubling the payout if it participates in the formation of the prize chain. In addition, Wild symbol is able to bring steep wins on his own:

  • Two wild symbols - 10 coins
  • Three wild symbols - 200 coins
  • Four wild symbols - 2000 coins
  • Five wild symbols - 10,000 coins

Scatter symbol. The ram with the golden horns in the game is a symbol of scatter. The round of free spins launches the emergence of 3,4 or 5 such images. Also, this sign brings payouts (it is enough to put two scatters on reels) in the amount of 2, 5, 20 and 500 coins.

Bonus games and functions:

As we have already noted above, Thunderstruck video slot does not have a lot of bonus options. In this case, we will talk about free spins and a game for doubling.

Free spins:

Free SpinsThis function is launched by the appearance of three or more scatter symbols, which give the right to 15 prize rounds with multiplication of the win by x3. The victories during free spins can reach x200 total bets, but on average, this parameter is x30. It is safe to say that the biggest payments in the game occur precisely here.

Gamble Feature

As for me, this is a standard risk game that launches after every victorious spin. You can play it, or you can refuse, taking away your winnings. In principle, this is a great way for a few seconds to significantly increase your winnings, but the chances of losing are 50%. You are proposed to guess the colour of the card (the winning is doubled) or accurately identify its suit, for which the winnings will increase 4 times. The number of attempts is not limited.


Thunderstruck slot machine is a representative of the old school with the simple graphics and limited bonus functions. Nevertheless, since its inception, it has remained one of the flagships in the Microgaming company`s portfolio, which has stood the test of time. In addition, the older it gets, the better it looks. This is a well-balanced video slot that emits simplicity and it is able to surprise with the excellent payouts. The only disadvantage of the slot machine is the obsolete graphics by the modern standards. In my opinion, wild symbols, free spins and RTP raising to 97% make this game very entertaining and deserving of your close attention.
