The basic loop
Step
When you load in, fuel items are scattered around the rocket at your starting point. You can grab those or head into a nearby challenge area and complete a minigame to earn fuel that way. Once you have fuel, add it to the rocket — the more you add, the higher your next launch goes and the more cash you collect when you land.
- Pick up fuel grab the items on the ground around your starting rocket or complete a challenge to earn some.
- Add fuel to the rocket open the upgrade UI next to the rocket and load in what you have collected.
- Blast off board the rocket when you are ready and launch; your earned cash is added after you land.
- Repeat take that cash, tackle more challenges, and keep pushing the rocket higher each run.
Getting fuel faster
Tips
Each island has its own set of challenges, so when one stops feeling productive you have two more to switch to. Completed challenges can be replayed, so nothing is ever a dead end.
- Move to a different dimension the moment you are struggling on your current island.
- Check your fuel gauge before you launch so you know exactly how much progress each session made.
- Replay cleared challenges when you need a steady, low-stress fuel income.
The three dimensions
Table
The three islands are independent, each with a distinct difficulty curve. You can travel between them freely at any point.
| Dimension 1 | beginner-friendly challenges; a solid first stop for learning the game and building early fuel. |
| Dimension 2 | mid-level difficulty with larger fuel rewards than Dimension 1. |
| Dimension 3 | the hardest challenges, but clearing them pays out the most fuel and cash of the three. |
Controls and movement
CheckMovement and camera use standard Roblox controls, so nothing here needs to be learned from scratch.
- Move with WASD and look around with the mouse, same as any other Roblox game.
- When you approach the rocket, a boarding prompt appears on screen.
- Adjust mouse sensitivity in the Roblox settings menu if challenges feel hard to aim or steer through.

Common questions
FAQWhy is my rocket not flying very high?
You need to add more fuel using the upgrade UI beside the rocket before you launch. The more fuel you load in, the higher each blast off takes you and the more cash you collect.
What is the fastest way to build up fuel?
Rotate through all three dimensions and clear challenges across the islands. Switching islands when you hit a wall keeps fuel coming in from multiple sources.
Which dimension should a new player start in?
Dimension 1 has beginner-friendly challenges and gives you a feel for how the game works. Once you are comfortable, move on to Dimensions 2 and 3 for bigger rewards.
Do I need to spend Robux to progress?
The core loop — collecting fuel through challenges and launching your rocket — is free to play.
