Rocket Fellas Inc (Thunderkick) Slot Review

Rocket Fellas Inc – Slot Overview 

Thunderkick’s Rocket Fellas Inc is a rowdy, high-octane slot adventure starring a crew of muscle-bound miners, an underground treasure vault, and — true to its name — an array of explosive rocket-powered features. While it may have initially drawn comparisons to Quickspin’s Dwarfs Gone Wild due to its cartoon dwarf mining theme, Rocket Fellas Inc quickly asserts itself as a distinctly Thunderkick creation with sharp visuals, satisfying mechanics, and a high-potential free spins feature. 

Built on a 5-reel, 4-row grid with 30 fixed paylines, the game brings a medium-to-high volatility punch with a strong theoretical RTP of 96.1% and a formidable max win potential of 7,325x your stake. The standout mechanics here are the Rocket Feature, which can transform symbols into wilds, and the explosive Sticky Wild Free Spins, which supercharge the bonus round for serious win potential. 

Playable on all devices and accepting bets from €0.10 to €100 per spin, Rocket Fellas Inc is crafted for players who enjoy vibrant visuals and explosive feature action with the ability to generate massive rewards — if you can withstand the volatility.

Design and Graphics 

Rocket Fellas Inc immediately captures attention with its bold, cartoonish art style. The theme is a stylized mining operation deep within a cavern illuminated by glowing gems and rocket trails. Every character and symbol is exaggerated for impact, lending the game a comic-book sensibility. Visuals are sharp and animated with high-definition polish — gems gleam, rockets blaze, and wins erupt in satisfying bursts of color.Symbols include: 

Four low-paying gemstones: blue, green, yellow, and red. 

Five high-paying symbols: four miner characters and a glowing barrel, which doubles as a key element in the Rocket Feature. 

The barrel is the highest-value regular symbol, paying 30x the stake for five on a full payline. 

The wild symbol substitutes for all regular symbols and shares the same payout value as the barrel. 

The scatter symbol, styled as an iron fist, is the trigger to unlock free spins. 

Thematically, everything feels cohesive — from the industrial border of the reels to the drill-bit style buttons and pipe-laced frames. The game’s explosive nature is well expressed through both visuals and pacing, keeping things lively from the first spin.

Gameplay Mechanics 

At its base, Rocket Fellas Inc plays like a traditional 30-payline slot, awarding wins for three or more matching symbols from left to right. However, Thunderkick spices things up with the Rocket Feature, an unpredictable and rewarding mechanic that can appear at any moment. 

The Rocket Feature 

During any spin, one or more rockets may appear on the leftmost reel. 

The rocket flies horizontally across the same row it lands on. 

If it hits a barrel symbol, that barrel transforms into a wild. 

Any additional barrels in the same row also transform into wilds. 

This feature is particularly powerful when multiple rockets and barrels align, giving the base game surprising pop. 

These rockets introduce a reactive element that breaks the usual rhythm and helps add excitement to base gameplay — especially when they create high-value wild-filled rows.

Sound and Music 

Rocket Fellas Inc doesn’t shy away from its theme, even in its sound design. The funk-infused soundtrack leans into an energetic, bass-heavy groove that plays throughout the session, keeping things upbeat and modern without becoming repetitive. 

Sound effects are punchy: rocket launches are loud and dramatic, symbol transformations land with metallic clinks, and wins are celebrated with arcade-style explosions. The audio complements the action on screen without overshadowing the gameplay — subtle during idle spins and intensifying during rocket flights and bonus rounds.

Bonus Features 

The true highlight of Rocket Fellas Inc is its Free Spins bonus round, which dramatically elevates the game’s winning potential through Sticky Wilds and Hot Reels.Triggering Free Spins 

Land 3, 4, or 5 Iron Fist scatter symbols to earn: 

10, 15, or 20 free spins respectively. 

During the bonus, landing 2+ scatters retriggers the round: 

2 scatters = +3 spins 

3 scatters = +10 spins 

4 scatters = +15 spins 

5 scatters = +20 spins 

Sticky Wilds and Hot Reels 

In free spins, any barrel turned wild becomes sticky, remaining on the reels for the rest of the round. 

Additionally, any reel containing a sticky wild becomes a Hot Reel. 

Barrels that land in Hot Reels automatically turn wild — even without the Rocket Feature. 

This creates compounding potential: the more sticky wilds you collect, the more Hot Reels you activate, dramatically increasing your odds for massive hits. 

Note: Sticky wilds can’t appear in reel 1, since it’s reserved for rocket launches. But the remaining four reels offer enough space for wild build-up and screen-filling combos. 

This combination of sticky mechanics and re-triggers gives Rocket Fellas Inc one of the most explosive and snowballing bonus rounds in Thunderkick’s portfolio — and the key to achieving the slot’s maximum payout of 7,325x the stake.

Betting Options and Payouts 

Rocket Fellas Inc is designed to accommodate a wide range of players. You can stake as little as €0.10 or go up to €100 per spin, offering flexibility whether you’re cautious or bold. 

The RTP is a steady 96.1%, and while the volatility leans medium-high, the game is generally fair. Base game payouts are reasonable, with enough Rocket Features to keep things moving, while the real win potential lies in the free spins round. 

With the top symbol paying 30x for five of a kind, and full-screen possibilities boosted by stacked symbols and the Rocket Feature, players can occasionally hit sizeable base game wins. But in the bonus round, especially with Hot Reels activated, it becomes a whole different game — with multiple sticky wilds in place, wild rows, and retriggered free spins chaining together into a big payout.

Conclusion 

Rocket Fellas Inc is a chaotic, feature-rich slot that manages to feel both classic and contemporary. Thunderkick successfully delivers an experience that blends traditional slot mechanics with layered features and enough audiovisual flair to make each session feel dynamic. 

The Rocket Feature in the base game adds just enough surprise to keep spins interesting, while the Sticky Wild + Hot Reels combo in free spins is truly explosive. It’s a game with real build-up, where the longer you last in the bonus round, the more your potential skyrockets. 

While some may wish for a 1024 ways-to-win setup to modernize the 30-payline limitation, the smart symbol stacking, wild synergy, and retrigger mechanics help balance it out. The maximum win of 7,325x puts it comfortably in the high-potential camp, and the cartoon style is likely to appeal to a broad demographic. 

Ultimately, Rocket Fellas Inc is a prime example of what Thunderkick does best — quirky, explosive, and surprisingly deep gameplay dressed in stylish visuals. It’s volatile, fun, and full of personality. 

So if you’re in the mood for a blast, Rocket Fellas Inc is ready to light the fuse.
