Thunderstruck Wild Lightning Slot Game Design

Microgaming has spared no expense with the design of Thunderstruck Wild Lightning. The game features superb graphics and some really cool animations. Thor and Norse Mythology are at the heart of this game, and the slot does a great job of bringing them to life. Players also have the option of choosing which soundtrack plays as they spin the reels, with five awesome Norse-inspired tunes to choose from.

Thunderstruck Wild Lightning Slot Gameplay Features

Setting up and playing the Thunderstruck Wild Lightning slot game is nice and easy. While the screen itself might look quite busy, the gameplay is straightforward. Firstly, players need to choose their bet value – the minimum that can be wagered is $0.20, while the maximum is $16. This may not seem like a huge range, but it is compensated by the massive payouts that can be won when playing for real money.

If you want to sit back and let Thor and the slot do the heavy lifting, then it comes with the standard Autospin button you can find on most top online slots. The action takes place across a standard 5x4 set-up, with 40 fixed paylines being in place.

Playing Thunderstruck Wild Lightning Mobile Slot

Microgaming always takes the time to make sure their top online slots look fantastic on mobile devices, and the Thunderstruck Wild Lightning mobile slot is no different. The stylish graphics and animations have all been maintained on the switch to the smaller screen, as have all of the features.

Microgaming is a huge developer, so you can find its titles at most top online casinos offering mobile play.

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 colored 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 of 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.

Thunderstruck Wild Lightning Slot Jackpot, Max Payout & RTP

There are some very beefy prizes that can be won here. The Thunderstruck Wild Lightning jackpot feature allows players to win up to 15,000x their total stake. If you are betting the maximum stake of $16, then the most amount of money you win is an eye-watering $240,000.

The RTP for the slot is listed by Microgaming as 96.10% and the volatility is high.

Thunderstruck Wild Lightning Slot Summary

Your thoughts on progression-based features are going to determine how much mileage you get out of Thunderstruck Wild Lightning. If you are looking for a slot that offers easy-to-access bonuses and the Free Spins Round, then you may want to look elsewhere. If you don’t mind persevering to unlock features and be rewarded in the long run, then give Thunderstruck Wild Lightning a spin. The Wild features here, once unlocked, can really help boost your winnings, getting to them just takes some time.

Outside of the features, there is still plenty to enjoy here. The gameplay is simple but effective, and the graphics are good. The high volatility will no doubt turn away a few players, though, as will the lack of higher betting options.

Look for the Thunderstruck Wild Lightning slot at the best online casinos.
