Thunderstruck II Slot Review 2026: Play Free & with Real Money

The original Thunderstruck was one of the most popular online video slots. It’s, therefore, hardly surprising that they released the Thunderstruck II slot a while later.

The sequel, as you would likely expect, is an upgrade on the original. The base game is played on a classic 5 reel and has 243 fixed pay lines. However, what makes this game really stand out is the fact that it has four distinctly different bonus games.

A closer look

Not only is this game one of the most popular sweepstakes games to play, it is probably one of the most popular Norse mythology-themed slots there has ever been. Testament to that is the fact that it was launched in 2010 and is still going strong.

On the face of it, things look fairly simple - it is played on a 5x3 reel, like most video slots, but has slightly more paylines at 243. The symbols are also fairly standard, with the low-ranking ones being named from playing cards and the higher-ranking symbols following the theme.

Where to play 

You can play this slot at all online sweepstakes casinos with Microgaming games in the lobby. You can compare the best operators using the expert reviews here at TheGameHaus, and discover bonuses like Stake.us’, who offers a 5% rakeback on your losses when using our exclusive promo code TGHSOCIAL.

Bonus games and features

While the base game is similar to Leprechaun Riches slot and many other games, what sets Thunderstruck 2 apart is its bonus features. As well as scatters, wilds and expanding wilds, you also have four free spins symbols.

Each of these free spins symbols triggers its own unique bonus game as follows:

• Valkyrie: 10 free spins and all wins are multiplied x5
• Loki: 25 free spins with a Wild Magic feature
• Odin: 20 free spins with a Wild Raven Feature
• Thor: 25 free spins with a rolling reels feature

Conclusion

Slots don’t maintain a level of popularity for over a decade for nothing - this slot really is the “reel” deal. The theme is prevalent, the base game is efficient, and the four bonus games ensure never-ending fun.

Thunderstruck II will certainly be one of these. Our verdict? Go play it right away!
