Redeeming codes early gives you free items that speed up that growth before you have spent any time grinding for them.
- Find a training machine walk up to one and click or tap it to start building strength
- Watch your character change muscle growth happens in real time as you train
- Open Settings click the Settings button in the upper-left corner of the screen
- Enter your codes type each code into the CODES box exactly as written, then press Enter to collect the reward
- Pick up a pet pets boost your training speed, so grab one as soon as you can
- Check your strength target the game shows you what you need to unlock the next character, so keep that number in mind
How codes work and where to find them
StepCodes are published by the developers through the social links listed on the game's page, so that is the right place to check. Capitalisation matters when you type a code, so copy it carefully. As of September 12, 2026, there are five working codes tracked for this game.

What to focus on as you progress
TipsOnce your strength climbs, the game opens up into new worlds with tougher challenges and bigger rewards. Each character you unlock is more powerful than the one before it, and clearing a character fully triggers a rebirth that lets you push even further.
- Train on machines constantly
- Use Strength Potions as soon as you get them rather than sitting on them
- Get a pet early since it directly raises how fast you train
- Move to a new world when your strength is high enough — harder worlds bring better rewards
- Unlock each new character the moment you meet the strength requirement
What to check when you feel stuck
Check
Progress can feel like it has stopped even when the solution is straightforward. Run through this list before assuming you need to spend anything.
- Do you have a pet equipped? Training without one is noticeably slower.
- Have you entered every available code? Unused codes mean free potions and spins left on the table.
- Are you actually using your Strength Potions, or are they sitting unused in your inventory?
- Have you let the game idle for a while? The automatic training gains can close a gap without you doing anything.

Common questions
FAQCan you enjoy this game without spending any Robux?
Yes. Codes give you free Strength Potions and Wheel Spins, and the idle system keeps building your strength automatically. Early and mid-game content is fully reachable without buying anything, and later characters are possible with enough patience.
Where do you find codes to redeem?
The game page directs you to the developers' social links as the place to find codes. Codes have expiry dates, so enter them as soon as you find one rather than saving it for later.
How do you unlock the next character?
Each character has a strength requirement you can see inside the game. Keep training until the number is met, and the new character becomes available. Completing a character also triggers a rebirth that opens further progression.
Is this a game you have to play actively, or can you leave it running?
Both styles work. The game includes an idle system that trains your character automatically while you are away.
