Thunderkick casino games are made by an independent Stockholm studio whose catalogue moves between fixed paylines, connecting ways and cluster wins. Its best-known series keep recognisable characters while changing the reel system, multiplier progression and volatility around them.

The company began in 2012 and says it designs and develops its games in-house, supported by its own remote gaming server. In 2026, Thunderkick described 3 Wildos as its 100th game, a more useful dated milestone than an older “80-plus” portfolio claim.

For players, the strongest pattern is controlled reinvention rather than one universal mechanic. Esqueleto Explosivo, Pink Elephants and Midas Golden Touch have each returned in mechanically different versions, while standalone releases range from nine paylines to hundreds of connecting ways.

How Thunderkick developed

Thunderkick identifies itself as an independent studio based in Stockholm, with games, art and features produced inside the company. Its careers material also describes a supporting RGS, the server system that delivers the games and records their play.

The business operates as a game developer and B2B supplier rather than a casino or an aggregator. Public records identify Thunderkick AB and Thunderkick Malta Limited, but the evidence reviewed for this page does not establish a wider parent company.

Britain’s Gambling Commission register lists Thunderkick AB under account 40165 and Thunderkick Malta Limited under account 41752. This confirms the supplier entities in that market; it does not mean every operator carrying a Thunderkick title is licensed for every country.

Growth has come through new games, sequels and rebuilt editions. The 100-game milestone in 2026 shows the scale reached since 2012, while the recurring Reborn label signals that older ideas can return with different mathematics and feature sets.

Inside the Thunderkick catalogue

Thunderkick’s earlier public material described more than 80 titles, and its later milestone called 3 Wildos game number 100. These dated figures show expansion, but neither should be treated as a permanent live-catalogue total.

The visual identity is easier to recognise than a single reel format. Day of the Dead musicians drive Esqueleto Explosivo, Pink Elephants uses surreal jungle imagery, Midas Golden Touch turns Greek myth into a gold-covered line game, and Gods of Rock places mythic figures on a concert stage.

Other themes include the science-fiction Egypt of Pyramyth, the Norse setting of Odin’s Gamble and the griffin hunt in Beat the Beast. Across this sample, bold character animation and music carry as much identity as the symbols, although that is an editorial observation rather than a provider-wide technical rule.

The underlying structures vary sharply. Midas Golden Touch 2 and Griffin’s Gold Reborn use compact 3×5 line layouts, Pink Elephants Trinity starts with six reels and thousands of ways, and Esqueleto Explosivo 3 uses a 5×5 cluster grid.

Reborn does not mean the original mathematics have simply been restored. A rebuilt title can change RTP, volatility, maximum exposure, route count and bonus access, so it belongs to its own version rather than serving as a substitute for the older game sheet.

How Thunderkick features work

Cascades are central to the Esqueleto series. In the original Esqueleto Explosivo, a winning combination disappears and symbols drop into the gaps; another win can then form without a new paid spin.

Explosivo Wilds substitute and remove surrounding symbols, while successful reactions advance the Mucho Multiplier through a 1×, 2×, 4×, 8×, 16× and 32× ladder. The sequence resets when the cascade ends, which gives each paid spin a clear build-and-reset rhythm.

Esqueleto Explosivo 3 changes that idea to Cluster Pays. Five or more matching symbols must connect horizontally or vertically, an Explosivo Wild clears a 3×3 area, and new symbols fall in for another avalanche.

Three scatters start ten free spins. During that bonus, every third collected Explosivo Wild adds a spin and removes the lowest multiplier level, while the Mucho Multiplier can reach 1,024×; that is the feature multiplier ceiling, not the game’s overall maximum exposure.

Connecting ways take a different route from paylines and clusters. Wins form through matching symbols on adjacent reels across a stated number of routes, so a symbol need not sit on one drawn line; the exact route count still belongs to the individual title.

Pink Elephants Trinity begins with 4,096 ways and turns its bonus into a six-level collection. Three or more peanut scatters start the feature, collected peanuts move it towards a 144-peanut target, and Sticky Wilds plus unlocked spirit animals affect the intermediate levels.

Reaching the final level adds a seventh reel in the centre, raises the total to 16,384 ways and removes symbols other than Pink Elephants. The expansion is therefore the end of a tracked objective, not a random increase applied to every spin.

Thunderkick also returns to compact line games with wild-led bonuses. Midas Golden Touch 2 uses Multiplier Wilds, a Gift of Midas event and Sticky Respins with an Epic Wild, while Griffin’s Gold Reborn combines a roaming wild, wild multiplier and free spins on nine paylines.

These labels should not be treated as interchangeable systems. Sticky Wins, Sticky Respins and Roaming Wilds describe different title-level rules, and the public evidence does not support one universal Thunderkick movement or persistence pattern.

RTP configurations and volatility

The sample spans low, medium, high and very high volatility, so neither the Thunderkick name nor a familiar series predicts the playing rhythm. The original Esqueleto sits at 96.00% and low volatility, while the third game moves to 94.22% and high volatility.

That difference affects two separate things. RTP is a long-run theoretical return for the identified build; volatility describes how unevenly its results are distributed and cannot be inferred from the RTP or theme.

“Up to 96.00%” for Pink Elephants Trinity is also a configuration limit rather than a promise that every version uses 96.00%. Thunderkick’s own pages can change between builds: Pyramyth Reborn currently lists 96.05%, while an older official PDF gives 96.17%.

The correct comparison is therefore between named versions. A sequel or Reborn edition may share artwork and feature vocabulary with its predecessor while using a different return, volatility label and prize ceiling.

Fixed maximum exposure and jackpots

Thunderkick reports large prizes as maximum exposure, a fixed multiple of stake rather than a changing jackpot pool. Griffin’s Gold Reborn leads the verified sample at 22,222×, followed by Gods of Rock Reborn at 20,000× and Odin’s Gamble Reborn at 19,333×.

Midas Golden Touch 2 and 3 are listed at 15,000×, Pink Elephants Trinity at 14,400× and Pyramyth Reborn at 10,000×. These figures are ceilings for the stated game versions, not expected bonus results and not evidence of how frequently a large win occurs.

No official page or game sheet in the reviewed sample establishes a Thunderkick progressive, local or network jackpot. A feature buy, fixed exposure figure or bonus reward does not become a progressive simply because it offers a large amount.

Strengths, limitations and player fit

Thunderkick’s clearest strength is that a returning series can change its playing structure without losing its theme. The Esqueleto games move from 17 lines to 99 ways and then clusters, while their multiplier-and-destruction identity remains recognisable.

The catalogue also covers a useful structural range: simple paylines, connecting ways, cascades, clusters, sticky respins, roaming wilds and multi-level collection. Official pages publish RTP, volatility and maximum exposure for many named versions, which makes comparison more concrete.

The first limitation is that newer or rebuilt versions often move towards high or very high volatility and larger fixed ceilings. Players who prefer steadier low-volatility play have fewer documented options in the later sample than those comfortable with feature-dependent results.

The second is version complexity. Similar artwork can hide a different route count, RTP, volatility and bonus sequence, while labels such as Reborn, Sticky Wins and Roaming Wild do not define the full rules by themselves.

Thunderkick may suit players who enjoy strong music, unusual characters and bonuses that visibly progress through multipliers or collection levels. It may be less suitable if you want one familiar line structure, a narrow RTP band or a catalogue centred on progressive jackpots.

Where to start with Thunderkick slots

For cascades with the lowest documented volatility in this sample, start with the original Esqueleto Explosivo. Its 17 paylines, 96.00% RTP and 700× ceiling make the multiplier ladder easier to follow than the third game’s cluster system.

Choose Esqueleto Explosivo 3 for a 5×5 cluster grid, destructive wilds and a bonus multiplier that can reach 1,024×. Its 94.22% RTP and high volatility are the main trade-offs for that larger feature chain.

Pink Elephants Trinity is the route into connecting ways and a long collection objective, while Midas Golden Touch 2 keeps a compact 15-line layout with multiplier wilds and sticky respins. Griffin’s Gold Reborn is the very-high-volatility option for roaming wilds and the largest fixed ceiling in this sample.

Thunderkick is most distinctive when it revisits a familiar cast and rebuilds the mathematics around it. That creates genuine variety, but players need to treat each sequel and Reborn edition as a separate game rather than assuming the series name defines its risk.
