Norse mythology is a great source for dramatic imagery and themes, as one can see in Thunderkick’s Second Thunder. After all, this is a slot set in a dark and stormy evening where armies are set to clash against the gods themselves! How will you fare on this game’s 6 big reels? Experience the lightning by reading our complete Second Thunder review.



Thunderkick goes big in Second Thunder, with 6 reels and 5 rows. However it just has 50 paylines, which might sound like few compared to other video slots with a similar reel setup that can have thousands of winning combinations. Paylines are still formed in the traditional way, and always start from the leftmost reel.
The RTP of Second Thunder is set at 94.2%, which is quite low compared to the 96% average found in most slot games. The volatility is high, while wins can reach up to 12,500x the stake. If you reach this total during the free spins round then the round will end immediately, with no additional wins paid out. Bets can start from £0.10, allowing even players on a tighter budget to enjoy this one.
You can find Second Thunder at various online casinos, but choosing one can be tough. So, we have picked the best slot sites to inspire you.
Second Thunder goes for the fully dramatic Norse experience, being set on a dark and icy battlefield where armies are set to clash in the face of a raging storm. Get close to triggering a special feature and the storm comes to life, revealing the gigantic silhouette of the god of thunder himself. Add a full soundtrack and you get a game that both looks and sounds right for the theme it is going for.
The game’s reels hold 9 paying symbols. Of these 5 are the high pays, namely the viking, wolf, boar, serpent, and eagle. The shield, horn, axe, and helmet, on the other hand, make the low pays. The wild can substitute for any of these symbols in order to form more winning combinations. However it cannot substitute for the scatter, which will trigger the free spins if 3 or more hit the reels.
Let’s see how much each of the paying symbols is worth.
Second Thunder might be as epic as slots get, but it’s still perfectly playable on the small smartphone display. This is thanks to HTML5, the technology that allows developers to build games that are playable on any internet browser. The game’s visuals adjust automatically according to the size of your device and its display, although we recommend playing it in landscape mode for the optimum experience.



Second Thunder has some interesting bonus features, including one based around its wilds. Let’s see what they involve.
Landing wilds on 2 or more wilds in positions that create a rectangle triggers the Wild Field. This transforms all enclosed symbols into wilds. This field can expand to up to all the 6 reels, and the free spins can be triggered while a Wild Field is active.

We haven’t mentioned the extra row set on top of the regular reels. This is the Feature Row, which can hold up to 6 special symbols that are randomly activated during regular spins. When active it holds at least 1 wild or scatter plus multipliers of 2x, 3x, 5x, or 10x. If activated the multipliers are applied to wins involving symbols in their corresponding reel. In the case of multiple multipliers making part of the same win then these are added up and the total applied to the win.
Land 3 scatters anywhere on the reels for a round of 5 free spins. Any additional scatters add +2 spins each. The Feature Row is active on every spin during this round. The free spins can be retriggered by, once again, landing 3 or more scatters.

While Thunderkick looks to evoke the apocalyptic tone of Ragnarök in Second Thunder, it feels weird to admit that this slot just feels… pleasant. There’s nothing wrong with it, aside from an overly low 94.2% RTP, but while it does everything else right it only does so competently. Nothing immediately impresses aside from the visuals and music, and even then we’ve all seen slots that look even better. So yes, it’s big and looks nice, but Second Thunder feels more like a walk in the park than a battle for the End Times.
