Thunderstruck 2 has attained classic status since its release in 2010 and is one of Microgaming’s most popular slots. With a Norse mythology theme, the progressive free spins bonus round is highly innovative, with big payouts in the Wildstorm feature.
A 5-reel, 243 ways-to-win video slot, there are no formal paylines on Thunderstruck 2 – a winning spin is when symbols appear left to right on adjacent reels in any combination (except for scatter wins, which will pay anywhere on the reels). There are six different coin sizes – 0.01, 0.02, 0.05, 0.10, 0.20, 0.25 – and between 1–10 coins be played per spin (30 ‘lines’ are active for wagering purposes). The maximum bet ranges in size from $3 – $75, while the minimum bet per spin is 0.30. Winning spins are multiplied by the line bet, although scatter wins are multiples of the total bet.
The Wildstorm Feature is randomly triggered, and when in play up to 5 reels will turn Wild for one spin. If all 5 reel become Wild, the payout is 2,400,000 coins (up to $600,000).
The Great Hall of Spins is a progressive bonus feature which is activated by hitting 3x, 4x or 5x scatter symbols anywhere on the reels. The more often the bonus feature is triggered the greater the number of free spins that are awarded.
There are four different Halls in the Great Hall of Spins, each one named after a character in the game and each having different features. There are conditions that need to be met in order to be able to progress through the different Halls:
Valkyrie – You are given entry to this Hall the first time the bonus feature comes into play. You receive 10x free spins and these come with a 5x multiplier.
Loki – This Hall is entered after you have activated the Great Hall of Spins five times. In this round, you receive 15x free spins, and the Magic Wild feature is activated, where if the Magic Wild symbol lands on reel 3, other symbols randomly become Wild as well.
Odin – Entrance to this Hall comes when the feature has been triggered ten times. As well as 20x free spins, the Wild Raven feature is active. In this, ravens will randomly land on a symbol in a winning spin and add a 2x or 3x multiplier (which can increase to 6x if two ravens appear).
Thor – The last of the four Halls is entered once the feature has been activated fifteen times. This round gives you 25x free spins combined with Microgaming’s Rolling Reels special feature. Every Rolling Reel win also increases the multiplier in play, up to 5x.
In designing Thunderstruck 2, Microgaming has built on the success and popularity of the original by retaining the characters and overall Norse mythology theme of the 2003 version. However, this game looks even better than its predecessor and the heroic fantasy fiction design has great appeal. The music and soundtrack also fit in well with this theme, with winning spins being accompanied by crashing thunder or loud blasts on a trumpet, while each character in the Great Hall of Spins feature has their own distinct look, design and soundtrack as well.
A low-volatility game, the biggest jackpot available on Thunderstruck 2 is nevertheless a huge 2,400,000 coins, which could be worth $600,000 if betting the max. This jackpot is landed when all five reels turn Wild during the Windstorm feature.
There are also some good wins available both during base play and in the Great Hall of Spins, where multipliers of up to 6x can be awarded, while any base play win when the Wild symbol substitutes is doubled.
The best jackpots include 6000 coins or up to $1,500 for hitting 5x Thor’s Hammer Scatter symbols, while hitting 5x Wild symbols is worth 10,000 coins or up to $2,500 (when betting the max).
The progressive Great Hall of Spins bonus round and the Windstorm feature are the two most notable special features in Thunderstruck 2.
In addition, the game includes others such as the Magic Wild feature, Wild Raven feature, and Microgaming’s unique Rolling Reels. These are alongside Wild and Scatter Symbols, and the Wild Reels special feature.
