Read the review and play the popular Microgaming slot Thunderstruck II slot machine and play this online casino game for free without registration. No download is needed!


Thunderstruck II is the epic sequel of the original Thunderstruck game, which quickly became an all-time favourite. Featuring advanced graphics and sounds, this Microgaming video slot is definitely a one-up compared to the original game. It features 5 reels and 243 ways to win, which are permanently enabled, thus, you cannot enable a number of pay-lines. Fitting for the theme, players are greeted on the reels by Nordic gods Odin, Loki, and Valkyrie. Thor’s hammer is also featured in this game and it corresponds to the scatter symbol. With Thunderstruck II’s enhanced graphics and gameplay, you will embark on a true Asgardian adventure!

How to Play

The +/- buttons below the blue sphere symbol allow you to set the coin size, which can be between 0.01 and 0.05. Set the number of coins you want to bet (with the help of the Coins feature), bearing in mind that the maximum number of coins you can bet per line is 10. Start the game with the Spin button and place the maximum bet with the Bet Max button. Thunderstruck II features an AutoPlay option as well, and the speed of the game is adjustable under Options -> Game Play Settings -> QuickSpin for those who are looking for a more fast-paced gameplay.

Bonus features

The wild symbol is represented by the Thunderstruck II logo, which doubles the pay-outs of the winning combinations it helps create. The Wildstorm can appear out of nowhere granting you a free spin with 1 to 5 expanding wild reels (free spins cannot be re-triggered).

If it appears 3 or more times, the Bonus Hammer symbol (the scatter) lets you enter into the Great Hall of Spins, which allows you to play between 1 to 4 bonus games. This is a multi-level bonus feature, which, if triggered multiple times, it paves the way for further bonus features.

The Valkyrie bonus game can be played the first four times the Great Hall of Spins is triggered. If triggered for a fifth time, players will be able to play the Loki bonus game, while the 10th triggering will allow players to play the Odin bonus game. The fourth bonus game is the Thor feature, which can be played from the 15th triggering. Each of these bonus features have their own particularity or twist. For example, in the Odin bonus game, a Wild Raven symbol will turn other symbols into 2x or 3x multipliers. Likewise, in the Loki bonus game the Rolling Reels comes with 25 free spins, and consecutive wins have the ability to increase the multiplier up to 5x.


Albeit Thunderstruck II has a fixed jackpot amounting to 1000 coins, the in-game bonuses can land players extremely high pay-outs.

Bottom line: Released in 2010, Thunderstruck II is a worthy descendant of the original game. Its theme, graphics, sound effects and many bonus features will certainly appeal to video slot enthusiasts from all over the world. Playable on both mobile and in-browser, this Microgaming video slot comes highly recommended for all slot lovers out there!
