ThunderStruck II No Deposit Bonuses + Free Spins

About Thunderstruck II from Microgaming

One of the things you will note about the Thunderstruck II slot is how thematic it really is. The blue colouration of the backdrop, reels and menu bars adds spice to the theme. Your favourite Norse gods have been interwoven with runic-style high playing card icons, and other imagery from Norse mythology to create a superb title to play.

Thunderstruck II was one of the first 243 ways to win slots to debut in the online casino world. It was also one of the first to offer up randomly triggered bonuses. Both have become mainstays in slots ever since.

Thunderstruck II Bonus Rounds and Paylines

Thunderstruck II's Great Hall of Spins Bonus is triggered when players land 3 or more scatters (Thor's Hammer, Mjölnir) anywhere on the reels. To begin with, players will start in the Valkyrie Bonus, which offers 10 spins with a 5x multiplier. However, when they enter the bonus a fifth time, the Loki Bonus is unlocked. It offers 15 spins with Wild Magic symbols the third reel turning other icons into wilds. Enter the bonus a tenth time to unlock Odin's Bonus, which offers 20 spins with ravens which can randomly turn symbols into 2x and 3x multipliers. If you get both multipliers, they rise to 6x the normal rate of pay. Trigger free spins a fifteenth time to enter Thor's Bonus, which offers 25 spins with Microgaming's Rolling Reels feature. It raises the multiplier by 1x for each consecutive win you land, with winning symbols being removed from the reels and replaced by new ones. Entering the bonus round a twentieth time allows you to choose your own free spin feature from those listed above.

Thunderstruck II features 243 paylines spread over 5 reels, as we've said. You cannot adjust those lines, but coin values and the number of coins you stake per spin can be altered. This gives Thunderstruck II a wagering range which ranges from 30p per spin up to £15 a spin in all. The non-progressive jackpot in this slot is capped at 2,400,000 coins.

Why is Thunderstruck II So Popular?

Even today, many years after its release, Thunderstruck II reigns supreme. There have been plenty of Viking-themed slots, plenty of Norse mythology-themed slots and the like, but few are able to combine the elements together quite like this original game.

Thunderstruck II is just about graphics and imagery, though; there's a lot more to it than that, such as...

• Setting the Standards
  This was one of the first Microgaming slots (well, any slot really) to feature 243 ways to win and randomly triggered bonuses, features we take for granted in slots today.
• Wild Symbols
  These can substitute for all other symbols in the game, barring scatters. Wilds can also double the value of any winning combination in which they appear.
• Scatter Symbols
  These can trigger a free spin bonus round when 3 or more appear anywhere on the reels during a base game spin or a free spin bonus.
• Wildstorm Feature
  This is the randomly triggered bonus we mentioned. It can occur on any spin at all, and when it does, it can turn up to 5 reels wild at once, which will surely result in a big win being paid out.
• Free Spin Bonuses
  Thunderstruck II contains not one, not two, but 4 different free spin bonus rounds. They are offered progressively, being unlocked the more times you trigger the bonus feature. Each bonus comes with its own unique features, as you will see below...
