Run Star Simulator is a Roblox racing game by the verified BestBunny group where you train up your Speed on the treadmills, then put it to the test by racing other players for Wins. Along the way you hatch Eggs for a chance at new Pets, and equipping your best one gives your training an extra edge. It is a simple loop built around one goal: get faster than everyone else on the server.
Once your Speed and Wins start piling up, Rebirthing lets you trade your current run for permanent perks that make every future training session count for more. This guide covers how to play, the training and racing loop, tips for new players, and a FAQ, plus links to the codes and script pages at the bottom.

- Train on the treadmills. Every session builds up your Speed stat.
- Race other players. Winning earns you Wins to spend on upgrades.
- Hatch Eggs. Each one gives you a chance at a new Pet to help you along.
- Equip your best Pet. It sticks with you and boosts your training.
- Rebirth when you plateau. Trade your progress for permanent perks and start climbing again.
Run Star Simulator Gameplay: The Speed, Race, and Pet Loop
Everything in Run Star Simulator feeds back into one number, your Speed. Training grows it, racing puts it to the test against real opponents, and Rebirthing turns your progress into permanent perks that stick around for good.
| Way To Progress |
How It Works |
| Training Speed |
Practice on the treadmills to build up your Speed stat, the core number the whole game runs on |
| Racing For Wins |
Challenge other players to a race and cash in a win for Wins you can spend later |
| Hatching Eggs |
Open Eggs for a chance at new Pets, then equip your best one for an extra boost |
| Rebirthing |
Reset your run in exchange for permanent perks that speed up the next one |
The loop is easy to pick up. Train, race for Wins, hatch Eggs whenever you can afford it, keep your best Pet equipped, and Rebirth once your early training starts to feel too slow.

Tips for New Run Star Simulator Players
- Redeem codes first. A few free Wins and Speed give your early training a real head start.
- Train in short, frequent bursts instead of one long session, since Speed adds up either way.
- Do not skip Egg hatching. A strong Pet makes every future training session worth a little more.
- Join the group mentioned in the game’s own description, since new codes get posted there first.
- Do not be afraid to Rebirth once training slows down. The permanent perks are worth the reset.
