Thunderstruck Slot RTP, Details & Wager Limits
The Thunderstruck slot has 5 reels, 3 rows and 9 fixed paylines. To form a win, you need to land 3, 4 or 5 matching symbols across a payline, and beginning from reel 1. The exceptions are the 2 higher value symbols and the wild as you only need 2 in combination.
You can play from 9p to £45 per spin which is good as it caters to players with all types of bankrolls. Being produced in October 2003, it’s an oldie so newer concepts such as Autoplay and win/loss limits are not available. It does have a Quick Spin mode though in Settings. This isn’t available for UK players due to regulation.
The Thunderstruck 2 RTP is 96.1% which is average for a slot game. Medium variance, most of the bigger wins will come in the free spins due to the trebling multiplier. It has a hit frequency rate of 31.37% as nearly a third of spins will result in a payout.
The max win is 10,000 x bet per spin but it can reach 30,000 x your total bet per free spin. This is due to the trebling multiplier that is in play during the Free Spins feature.
Theme – join the God of Thunder
The Thunderstruck slot machine has a Norse mythology theme and has a dark, cloud-filled sky in the backdrop. The inspiration is the God of Thunder and Son of Odin, Thor. The graphics and animations are quite basic (as it was released in 2003) but it kinds of adds to the charm and appeal.
Symbols include A, K, Q, J, 10 and 9 royals. You’ll also see the Horn of Plenty (Cornucopia), lightning bolts, castles, Thor’s staff (Gríðarvölr) and Thor’s hammer (Mjölnir) on the reels. The Thor’s staff and hammer symbols are the highest paying giving you 0.33, 2.77, 11.11 and 83.33 x your total bet for 2, 3, 4 or 5 across any payline. A screen full of either will result in a 750 x bet payout.
Thor himself is the wild symbol with 2, 3, 4 or 5 in combination giving you 1.11, 22.22, 222.22 and 1,111.11 x your total bet. This means a screen full of Thor Wilds will give you a 10,000 x bet payout. The wild also replaces all symbols bar the Rams scatter.

Despite being released in 2003, Games Global have revamped the game using HTML5 technology. This means you can play the Thunderstruck slot on desktop, mobile and tablet devices. The simple 5×3 reel layout works perfectly on smartphone devices too.
Thunderstruck Bonus Features
The Thunderstruck slot game has 2 bonus features. You can benefit from double wild wins as well as free spins where up to 30 free spins can be won with a 3x multiplier.
Double Wild feature
Look out for the Thor Wild symbol. Any win involving the Thor Wild will double your win. Known as the Double Wild feature, a 5 of a kind win for the Thor’s staff or hammer symbols will see you pocket 1,500 x your total bet.
Free Spins feature
Thunderstruck slot is all about the Free Spins feature. This is played if you get 3 more Rams scatter symbols anywhere on the reels. 2, 3, 4 or 5 scatters will give you 2, 5, 20 or 500 times your stake. 3 or more will reward you with 15 free spins.
Furthermore, all wins are trebled as they are subject to a 3x multiplier. You can also trigger an additional 15 free spins (with a 3x multiplier of course) if you obtain 3 Rams scatters during the feature taking your total to 30 free spins with a 3x multiplier.
More importantly, a win involving the Thor wild symbol will give you a 6x multiplier effectively. However, a screen full of wilds symbols (10,000 x bet payout in the base game) will be trebled to give you a 30,000 x bet win.
Here’s a table that highlights what the max win is for each symbol in the base game, with the 3x multiplier in the free spins and the potential 6x multiplier in the free spins when involving a Thor wild symbol:
| Symbol | Base Game | 3x Multiplier | 6x Multiplier |
| Thor Wild | 10,000 x bet | 30,000 x bet | NA |
| Thor’s Hammer/Staff | 750 x bet | 2,250 x bet | 4,500 x bet |
| Castle | 400 x bet | 1,200 x bet | 2,400 x bet |
| Lightning Bolts/Horn of Plenty | 250 x bet | 750 x bet | 1,500 x bet |
| A/K | 125 x bet | 375 x bet | 750 x bet |
| Q/J/10/9 | 100 x bet | 300 x bet | 600 x bet |
Thunderstruck Review Summary – paved the way for future Norse mythology slots
The Thunderstruck slot is a simple game that is showing it’s age. It may look graphically dated but it’s become one of the most popular online slots of all time. The fact that the graphics are a little dated makes Thunderstruck more appealing to me than most newer slots.
This game is still in the top 10 most played slot games for many slot sites. As a result of its popularity, Games Global created Thunderstruck 2 (it’s sequel) which is visually better and has more bonus features. Saying that, the max win in the original game is much bigger.
The key to winning big is from the Thor Wild symbol. A screen full of them in the Free Spins feature will result in an almighty 30,000 x bet payout. It can still give you big wins of 4,500 x your bet for a screen of Thor’s hammer or hand symbols as well as a wild.
In conclusion, the Thunderstruck game is iconic and paved the way for future Norse mythology themed slots. As a result of it’s popularity, Games Global has also released Thunderstruck Wild Lightning and Thunderstruck 2: Mega Moolah. In late 2022, there will be a Thunderstruck Stormchaser slot.
