Second Thunder: Face the Wrath of Thor's Thunder and Fight for 12,500x Rewards

Second Thunder by Thunderkick throws you into a cold, smoky Norse battlefield where soldiers charge forward chasing multipliers up to 10x and a 12,500x max win. With that setup and a bit of fighter’s instinct, I joined this war against Thor to see how much damage it could actually do.

This is a six-reel, five-row slot with 50 paylines, built around a dark war theme with knights, wolves, and storm-heavy skies surrounding the grid. The RTP is set at 94.2%, and the volatility is high. So the odds were clearly not in my favour, but I still pushed through 200+ spins to see how it plays out.

I was landing wins every five to six spins, with my average returns sitting between 2x and 3x my bet. I could feel it sucking my balance away over time from the beginning. That said, the wilds and multipliers did step in occasionally. With my highest base game win reaching 42x my bet, along with a few 6x and 7x hits along the way.

If you land wilds on two different reels, it creates a rectangle that turns everything inside into wilds. Thanks to that feature, I managed a 23x win in the base game, which stood out at the time.

Alongside that, there’s the Feature Row, which randomly drops wilds, scatters, or multipliers up to 10x. I saw multipliers going up to 7x during my session, and when multiple ones land together, they stack before applying.

The bonus round is triggered by landing three or more scatters, starting with five free spins, with +2 spins for each extra scatter. The Feature Row remains active during the bonus, which is where most of the value sits. It took me nearly 90 spins to trigger it, and I ended up with a 111x return, which made the wait somewhat worthwhile.

There are also several feature buy options, ranging from boosting bonus chances up to five times to directly buying the bonus for 75x your bet. I didn’t rely on them much, but they are there if you want faster access.

In the end, I found Second Thunder depends heavily on its Wild Field and Feature Row to carry the payouts. The base game feels more like a slow build, and with those long gaps in between, it doesn’t always hold your momentum.
