Slots Like Rocket Fellas Inc: Rockets, Wilds and Hot Reels
Rocket Fellas Inc sends Thunderkick underground with a crew of cartoon miners, running on a fixed 5 reel, 4 row, 30 payline board rather than the shifting reel counts many modern releases favour. Rockets occasionally streak in on the leftmost reel, turning the symbol they land on into a wild and converting any barrel symbols sharing that same row into wilds as well, all while every symbol appears in tall stacks that boost the odds of a hit across several paylines at once. Landing 3, 4 or 5 Iron Fist scatters awards 10, 15 or 20 free spins, and inside the round any reel already holding a Sticky Wild turns into a Hot Reel, meaning every barrel that lands on it from then on converts into a wild too. Extra scatters during the round keep adding spins on top, from 3 more for a pair up to a full 20 more for five. RTP comes in at 96.1%, the medium to high volatility rating suits a steady session rather than huge swings, and the top prize on offer caps out at 7,325x stake.

The board runs a straightforward 5 reel, 4 row layout with 30 fixed paylines, rather than the cascading or Megaways formats common elsewhere. Four gem colours fill the low end of the paytable, while four cartoon miners and a barrel symbol pay out higher, with the barrel worth the most of the standard symbols at 30 times stake for five in a row. Every symbol on the board can appear in tall stacks, which raises the odds of a hit landing across several of the fixed paylines from a single spin.
Rockets streak in on the leftmost reel from time to time, and wherever one lands it converts that symbol into a wild. Any barrel symbols sitting on the same row as the rocket also transform into wilds, occasionally turning a modest looking spin into a much bigger payout once the fixed paylines are totalled up.
Free Spins and Hot Reels
Three, four or five Iron Fist scatters landing in the base game hand out 10, 15 or 20 free spins in turn. Once the round begins, any reel that already holds a Sticky Wild flips into a Hot Reel, meaning every barrel symbol that subsequently lands there also converts into a wild for the rest of the round. The leftmost reel cannot generate a Sticky Wild itself, since that is where the rockets land instead, which keeps a full screen of wilds just out of reach even in a strong run. Extra scatters landing during the round add further spins on top, from 3 more for 2 scatters up to a full 20 more for 5.
Pros and Cons
Pros
- Stacked symbols on a fixed 30 payline board give the base game a steadier, more frequent hit rate than many modern formats
- The Rocket feature adds a genuine surprise element to otherwise ordinary looking base game spins
- Hot Reels turning every barrel into a wild for the rest of the free spins round can snowball into some serious payouts
- Extra scatters retriggering the round keep a strong free spins session going rather than cutting it short
- Thunderkick’s cartoon mining dwarf presentation is charming and full of character
Cons
- A fixed 30 payline structure feels dated next to the Megaways and cluster formats many newer releases use
- The leftmost reel never generating a Sticky Wild rules out the very biggest full screen scenarios
- A 7,325x ceiling is modest compared to several other high volatility Thunderkick releases
- Rockets can go quiet for long stretches, leaving the base game feeling flat between hits
Game Screenshot
The free demo runs at Rocket Fellas Inc’s full 96.1% RTP, and since the Rocket feature and Hot Reels can both go quiet for stretches, give it a proper run to see them land before switching to real stakes.
Expert Take
Reviewers tend to see Rocket Fellas Inc as a well made but comparatively old fashioned release, with the fixed payline structure drawing the most criticism next to the shifting reel counts that dominate more recent slots. The Hot Reels mechanic during free spins is generally viewed as the game’s strongest idea, giving stacked wilds a genuine chance to snowball once a Sticky Wild lands in the right spot.

About the Developer
Rocket Fellas Inc comes from Thunderkick, the Swedish studio known for packing personality into its symbol animations and presentation as much as its feature sets. The Rocket and Hot Reels mechanics show Thunderkick leaning into one strong, clearly signposted idea rather than layering on several competing bonus systems at once.

Our Verdict on Rocket Fellas Inc
Rocket Fellas Inc holds up well despite its fixed payline structure, largely because the Rocket feature and Hot Reels mechanic both give the game a genuine sense of surprise that many newer, more mechanically complex slots struggle to match. It will not appeal to players who have moved on entirely from fixed paylines, and the 7,325x ceiling is modest by current standards, but the combination of stacked symbols and a well designed free spins round makes for a solid, characterful session.
