01

First things to do when you join

Step
In short Train your arms before you try the track — length and power are what make your launch go far.

When you first load in, head straight to the training equipment to build up your power and arm length. Once your arms are long enough, you can run the rainbow track and start racking up Wins. Those Wins are what unlock new arms and equipment.

  1. Hit the training gear use the training equipment to increase both your power and your arm length.
  2. Run the rainbow track when your arms are long enough, launch yourself down the track and see how far you fly.
  3. Stack your Wins every Win you earn unlocks new arms and equipment.
  4. Clear Grass Playground beating the first world is what opens the path to everything that follows.

World order and what to expect

Summary
In short Work through the worlds in order — each one you finish proves you are strong enough for the next.

There are at least four worlds in the game, and you tackle them in a fixed sequence. Each world you complete earns you a badge and lets you push into harder territory. The deep-sea world brings its own arms and training equipment themed around the ocean.

  • Grass Playground the starting world; clear it to earn the Meadow Champion badge and move on.
  • Frozen Peaks the icy second world; finishing it earns the Frost Champion badge.
  • Lava Volcano a high-difficulty world; beating it earns the Volcano Champion badge.
  • Deep Sea (World 6) a colorful underwater world with ocean-themed arms, training equipment, and deep-sea pets.
03

How rebirth works

Tips
In short Rebirthing resets your progress in exchange for multipliers and diamonds that make future runs faster.

Rebirth is a reset mechanic that gives you something valuable every time you use it. Your first rebirth earns you the Stronger Than Before badge. Each rebirth gives you multipliers and diamonds, and you restart in a stronger state each time.

Tips worth knowing
  • Your first rebirth unlocks the Stronger Than Before badge.
  • Each rebirth raises your growth multiplier, so training becomes faster after every reset.
  • Diamonds drop every time you rebirth — they are a separate reward on top of the multiplier.
  • You restart in a stronger state each time, not a weaker one.
04

Pets and why to hatch them

Check
In short Pets boost your training output.

Pets come from eggs, and once hatched they strengthen your training results. The deep-sea world adds its own set of deep-sea pets on top of whatever you have already hatched.

  • Hatch eggs pets boost your training.
  • Look for deep-sea pets once you reach World 6 they are only available there.
