Thunderstruck II review

Thunderstruck II

The year 2010 brought lots of excitement with it, because it was right around the time Microgaming announced a sequel, to one of the most popular online slots in recent times – Thunderstruck. Thunderstruck II is a revamped, enhanced version of its very popular 2004-released predecessor. Despite what the name suggests, Thunderstruck II is more than just a sequel. It features a 243-way video slot and runs, obviously, on the Microgaming platform.

It offers a much more detailed theme, and the graphics have been greatly improved, running on newer specs than the first installment of the game. More Nordic gods have been added to the mix including Odin, Loki, Valkyrie and Thor as symbols on the  reels. This includes new symbols: the bonus symbol, the ship and Thor’s home.

During the course of the game, the first feature you’ll come across is the wild multiplier, which is represented by the Thunderstruck Logo. This will double the payout of any combination it completes on the reel as a wild symbol. If multiple winning combinations of multiple symbols are revealed on a pay line, it can also create its own winning combination. The game’s scatter symbol is represented using the Bonus Hammer which completes any winning scatter combination when two or more of the scatters are present.

Once you’re able to achieve 3 or more Bonus Hammer icons, this will trigger the ‘Great Hall of Spins’ bonus game. Here, you can play any one of four bonus games: the Valkyrie Bonus Game, the Loki Bonus Game, the Odin Bonus Game and the Thor Bonus Game. However, in order to unlock three of these bonus games, you will have to trigger the Great Hall of Spins a specific number of times first. Each awarded bonus game awards a different number of free spins and a bonus feature on top of it.

Thunderstruck II Bonus games

There are four different bonus games within the main game itself. Each of these has different awards and is triggered different ways.

The Valkyrie Bonus Game is completely free and is unlocked for everyone. It awards the player 10 free spins and multiplies all wins by 5 during the free spins, which you can re-trigger. If 3 or more Bonus Hammers emerge, an extra set of free spins will be awarded, on top of those you already have.

The Loki Bonus Game can be played once the Great Hall of Spins Bonus game has been activated 5 times and awards 15 free spins. When one of the famous Wild symbols appears on the third reel, any number of regular symbols, to a maximum of 14, are converted into wilds. Free spins can be re-triggered.

The Odin Bonus Game can be unlocked one the Great Hall of Spins Bonus game has been activated 10 times, at which point it will grant an extra 20 free spins. Any win while in this bonus game will trigger the Wild Raven Bonus feature. Here, symbols are randomly transformed into wild multipliers. Players can be awarded up to a x6 multiplier on the amount you win, so long as it contains a wild card. However, this feature cannot be re-triggered during free spins.

The Thor Bonus Game is only playable after the Great Hall of Spins Bonus game has been triggered 15 times and rewards the player with 25 Free Spins. Any win while in this mode will trigger the Rolling Reels feature, where the symbols will explode and disappear after the player has been paid out. The symbols that are above the exploding icons at the time will fall to accommodate the now empty spaces and award the payout with a x2 multiplier. The multiplier may then increase in value by one to a x5 maximum. This game cannot be reactivated during Free Spins.

How to Play

Before you start to play the game, you should change your wager to your preferable stake using the plus and minus symbols. The coin value ranges from 0.01 to 0.05. The ‘coins’ alter the number of coins you want to bet, ‘Spin’ sets the game in motion and ‘Bet Max’ spins the reels at the highest wager.
