Thunder vs Underworld

Thunder vs Underworld made an appearance on the scene in October 2024, brought to life by the busy team at Pragmatic Play. Not to sound dramatic, but the volatility and RTP setting of this game are on fire. Players can pick between 2 modes: highly volatile with Zeus or even more volatile with Hades, both with the ability to reach the highest reward of 15,000x.

The Bonus Buys also come with 2 options: standard and special free spins, and they are quite pricey – from 75x to 300x your play amount. This is what I love most about Thunder vs Underworld – the choice of Bonus Buy options. Depending on your strategy (and your mood), you can side with the Thunder God for electrifying wilds or descend into the Underworld for fiery multiplier madness. I believe this is the kind of variety that makes every spin feel fresh.

With enhanced odds of 98.04%, we can definitely enjoy the dynamic battle between the opposing forces – lightning strikes and fiery chaos – each delivering a good set of features, from wild multipliers to expanding wilds. The slightly disappointing part? This is only a spin-off; and you’ll notice it too if you’ve already tried Zeus vs Hades: Gods of War.

If you want to give Thunder vs Underworld a go for free, you can play it right here, thanks to our demo option. In case you’ve already decided to play for real prizes, Stake.us is the place to be! But before you start spinning the reels, see its ups and downs and check the stats out to see what my 200 spins on Thunder vs Underworld were like.

About Thunder vs Underworld: Game Overview

With a 5×5 reel setup, 15 fixed paylines, and 2 unique modes (Thunder AKA Zeus and Underworld AKA Hades), Thunder vs Underworld lets you pick your side in an electrifying clash of gods. You’ve got Zeus, who brings high-volatility spins, while Hades cranks it up with very high volatility, all backed by an RTP of 98.04% or 98.00%, depending on the mode.

The symbols, ranging from goblets and helmets to phoenixes and lions, bring Greek mythology to life, just like the expanding wilds with up to 100x multipliers and sticky wilds during free spins that keep the wins coming. That is if your pockets are deep enough to survive the high volatility, but I’ll get more into that in a bit.

Want in on the action? Then I suggest you use the Bonus Buy to dive straight into free spins for 75x or 300x your bet in Thunder Mode, or 150x or 300x in Underworld Mode. Plus, with a 15,000x max win potential, this is one slot where the stakes are as legendary as the gods themselves!

And what’s there to say about Pragmatic Play that the SweepsKings team already hasn’t discussed? They remain one of the most popular software providers and surely have been one of the biggest slot suppliers in the past year.

My only remark is that I’d love to see some new unique features rather than spin-offs. But in the case of Thunder vs Underworld, I’m satisfied with Stake’s decision to enhance the odds and make it worthwhile!

Thunder vs Underworld Slot Information

Thunder vs Underworld is built on a 5×5 reel grid with 15 fixed paylines, bringing pretty standard gameplay where you win by landing matching symbols across paylines from left to right.

Unlike cluster-style slots, you won’t find tumbling reels here. Instead, the focus is on landing high-value symbol combinations. Zeus and Hades are the top-paying icons, with payouts that can reach up to 20x your bet for five-of-a-kind.

You can adjust your bet level setting the coin value and total play amount, with the minimum starting at 0.10 SC and reaching a maximum of 2,000 SC per spin.

To start playing, simply set your preferred play level using the intuitive controls below the reels, hit the spin button, and watch the reels come alive with mythological flair. The game’s symbols include both low-paying and high-paying icons, and of course, a couple of special symbols:

• Low-Paying Symbols: Standard card ranks (10, J, Q, K, A), rendered in a Greek-styled font. These pay 0.10 SC for 3 symbols, 0.5 SC for 4, and 1 SC for 5.
• High-Paying Symbols: Thematic icons like goblets, helmets, phoenixes, lions/hydras. These start as low as 0.5 or 1 SC and go up to 5 or 10 SC.
• Highest-Paying Symbols: Zeus and Hades are the most valuable symbols, with payouts of up to 20 SC for landing five-of-a-kind.
• Wild Symbol: Substitutes for all regular symbols to help form winning combinations.
• Expanding Wilds with Multipliers: This symbol triggers a powerful feature, and can appear on any reel, bringing multipliers ranging from 2x to 100x, depending on the mode.
• Scatter Symbol: Landing 3 scatters on reels 1, 3, and 5 activates the Free Spins feature, where expanding wilds lock in place for massive payout potential.

200 Spins Test of Thunder vs Underworld

What a ride! Would you believe me if I said I hadn’t had enough after 200 spins, even though I’ve already tried the original?

I loaded up my Stake.us balance to 100 SC and decided to try Thunder vs Underworld with 20 spins in Thunder mode, each with a play size of 2 SC. This left me with 61 SC, which only goes to show how crazy high the volatility is.

This is when I decided to buy Standard Free Spins, which meant heavily loading up my balance to 600 SC. Thanks to the expanding wilds, I won super high and almost doubled what I spent on the Bonus Buy.

I decided to continue in the Underworld for the next 70 spins, and I have to say I almost lost everything I previously got in the free spins round.

So, before my balance ran dry again, I decided to buy 10 Super Spins but now in Thunder mode, and I have to say, I was on edge until I got the second expanding wild on my 5th spin. This helped me get back up to a balance of 2,000 SC.

I spent the final 90 spins playing in both modes, and I ended up with 872 SC. I really had fun playing, even though it would have been better if I stopped after the mega win.
