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.
Pink Elephants Trinity runs on 6 reels with 4,096 ways to win in the base game. The Mystery Feature can inject up to 5 scatters before any spin, which sounds great until you realise it’s completely random. I’ve had sessions where it triggered 3 times in 30 spins, and others where I waited for more than a hundred spins without seeing it once.
The base game felt slow. Hit frequency is low, and I burned through 150 spins before landing a bonus naturally. The BET+ options help if you’re impatient, with Bonus Boost costing 2x your bet while tripling your chances. Bonus Boost Extreme costs 55x your bet and guarantees near-instant entry, but at 94.10% RTP, you’re paying for your own lack of patience.
That said, the bonus round is the real deal here, as in many ThunderKick slots. You need 3+ scatters to trigger 8 free spins, but after thi,s things really get interesting. The game has 6 progression levels, and you climb them by collecting Peanuts from Pink Elephants and scatters. Each level adds +3 spins and unlocks different feature animals.
Level 2 gives you Panthera, which marks wild positions with frames. Level 3 adds Jaguar, dropping wilds on reels 2-5 before each spin. Level 4 brings Bufo, upgrading sticky wilds into sticky Peanuts. I managed to hit it twice, and this is where things start really moving. For Level 5, the Mystery Feature activates on every single spin, making the climb to Level 6 feel possible.
I never reached the End Game at Level 6, but I’ve seen clips. It adds a 7th reel and converts everything into a massive elephant fest with 16,384 ways.
The symbols are split into low-paying (9, 10, J, Q, K, A) and the monkey family as high-paying. You’ve got the little monkey, teen monkey, grandma monkey, and the wise old monkey. The pink elephant is the highest paying symbol in the game.
As for whether it’s worth your time? This one is for those who are patient enough. If you need constant action, skip it, but if you’re the type who appreciates a slot with actual depth and doesn’t mind the slow burn to reach those ritual stages, Pink Elephants Trinity delivers once it finally gets going.
Thunderkick’s Esqueleto series gets a holiday makeover. Cluster pays, Avalanche mechanics, and multipliers that promise up to 1024x during Free Spins. Sounds festive, right? Not quite.
You get the familiar 5x5 grid with cascading reels and cluster pays. Land 5 or more matching skull symbols touching each other (horizontally or vertically), and you score a win. The Explosive Wild symbols are here too, clearing a 3x3 space around them and making room for new symbols to drop down.
The RTP sits at 94.22%. That’s low, especially in 2026. I’ve played slots with 96%+ that give me better value. This one felt stingy from the start.
The Mucho Multiplier climbs with every cascading win, starting from 1x and up to 32x in base play. I rarely saw it go past 8x during my sessions, though in the bonus game, I saw even up to 16x. Still not that much, considering the max multiplier in the bonus game is 1024x.
Explosive Wilds land and explode in a 3x3 radius. They appear quite often but rarely where they’re needed. They speed things up, but not to the extent that you’d expect them to.
The bonus game may just be its most redeeming quality. Either bought or hunted, it always paid close to the amount lost leading up to it. Each Explosive Wild gets marked in a meter at the bottom of the reels, and after 3 are collected, they award one more free spin.
There is also a Bonus Buy option at 94.40% RTP, barely better than base play. The BET+ options Bonus Boost and Bonus Boost Plus increase your trigger chances but cost more per spin. The Enrico Show guarantees an Explosive Wild on the first drop for 2x your bet.
This game takes the Esqueleto formula, slaps some Christmas decorations on it, and calls it a day. Exploding skulls and Christmas have no business being together, especially since Dia de los Muertos is its own thing. One celebrates death, while the other celebrates life. Diametral opposites.
If you’re a fan of the Esqueleto Explosivo series, you might find it enjoyable. Truth be told, you might be better off playing Esqueleto Explosivo 3 since it's basically the same game.

Thunderkick's commitment to innovation shines through, especially in its approach to game design. Instead of merely introducing new mechanics, they reimagine the very core of what makes a slot game. If you're in for an unforgettable gaming experience, Thunderkick's titles won't disappoint.
To familiarize myself with its slots, I started with the Flux, launched in 2014. The first thing I noticed is its RTP of 96.2%. The 5-reel video slot boasts 15 pay lines, a unique scatter-triggered bonus game, and bet levels ranging from €0.1 to €100. With its 33.58% volatility, players can potentially net a hefty max payout of €256,200 on a €100 bet.
Next up on my list was Lava Lava. The 2022 release with an RTP of 90.12% delivers a volcanic thrill on its 3x5 grid with 15 fixed pay lines, featuring Avalanche mechanics, Scatter explosions, and multiplier Wilds. With bet levels ranging from €0.1 to €100, and a 10,000 max bet multiplier, strategic play is essential.
Lastly, I switched things up a bit with Esqueleto Explosivo video slot. With an RTP of 96%, this 2015 release has a special place in Thunderkick's portfolio. With multipliers scaling up to a whopping 32x and a potential max payout of €70,000, this game promises thrilling stakes for bets ranging from €0.1 to €100.
Instead of merely adding new mechanics, Thunderkick transforms the foundational elements of slot games, promising players unparalleled gaming experiences.
This is evident everywhere - from titles boasting above-average RTPs and featuring unique bonus games to newer releases incorporating exciting features like Scatter explosions and multiplier Wilds.

Pans Arcadia
Pan's Arcadia has sharp mechanics. Managed a 120.00 payout when those x2 multipliers connected on a 20.00 bet. Hits feel balanced, making the gameplay worth the time.
Second Thunder
The Feature Row and wild mechanics are interesting and can create solid wins. However, the base game feels too stretched, with long gaps before anything meaningful happens.
Second Thunder
Hit a 4-shield combo and the payout barely covered my 20.00 bet. Mechanics are flashy, but these hits don't move the needle. Math feels tight for a 2/5 session.
Esqueleto Explosivo Feliz Navidead
This 456.00 win came straight from free spins after a rough base game session. Balance kept dropping, but once the multipliers climbed to x16 and x32 with stacked wilds, it added up fast. Around 110x total on my bet, which actually felt fair for once. Bonus carried it.
Pans Arcadia
The visuals are smooth and different from typical slots, but the gameplay has depth. Features like Mystery Respins and multipliers can create solid mid-range wins.
Pink Elephants Trinity
The base game almost put me to sleep, not gonna lie. 120 spins with small hits only. But when the bonus finally landed and I climbed to level 4, it paid 180x. Peanut stacking feels good. Just need patience and bankroll.
