Thunderstruck Wild Lightning Slot Free Spins & Bonus Features
Players are really spoiled when it comes to the Thunderstruck Wild Lightning bonus features. Firstly, there is the Lock & Win feature. This is triggered when players manage to land six of the glowing Thunderball symbols on their reels. When this happens, they will be locked in place, and players will be rewarded with 3 re-spins.
For the re-spins, all other symbols on the reels will be removed, and more Thunderballs will be added. If any of them land during the re-spins, then they will also be locked in place. Every time you land a new Thunderball, the re-spin count will reset to 3. Each one has a value on it, and when your re-spins have run out, all of the values will be added together and paid out. That isn’t all though, the grid itself can be extended once you land a certain amount of Thunderball, with the maximum size featuring 8 rows.
You will also notice some different coloured Thunderballs during the spins. These are to trigger one of four jackpot prizes in the game. There are three jackpots that can be won during the spins – Mini, Minor and Major – you just need to match one of the corresponding Thunderball to win this. In order to win the mega jackpot, you need to fill the reels with Thunderballs.
As if the Hold and Win feature and a progressive jackpot aren’t enough – the slot also offers several free spins rounds. This is a progressive free spins bonus, so the more free spins rounds you trigger, the more options become available.
To trigger the round, you will need three or more of the Hammer symbols. The first Free Spins Bonus is the Jotunheim Free Spins. This rewards players with 15 free spins with a Wild multiplier up to 5x. You can win up to 2,000x your stake and retrigger up to 30 spins.
Next is the Vanaheim Free Spins, which can be triggered after winning five free spins rounds. The feature gives up to a 6x multiplier, pays out 2,125x your stake, and gives you 12 free spins. This can be retriggered up to 24 spins. The Alfheim Free Spins can be triggered 10 times and gives 9 free spins, up to an 8x multiplier, and up to 3,250x stake payout. The Nidavellir Free Spins gives 6 free spins, up to a 12x multiplier, and can pay out 3,500x your stake.
There is one more Free Spins Round and Bonus Feature. The Wild Lightning feature occurs when a Wild lands on the symbols during any of the Free Spins Rounds. It will expand cover up to three reels for that spin. The final Free Spins Round is triggered when you’ve landed a total of 20 Scatters on the reel throughout your play. In this round, you only get one spin, but it comes with a guaranteed Wild Lightning feature that can cover all five reels.
