1 working Gym Star Simulator code
Checked against the live game on Oct 13, 2026. We read the codes straight out of the experience once a day and record the date each one appears, so the dates below are observations rather than a promise.
Codes
How to redeem a code
- Open Gym Star Simulator on Roblox and wait for your character to load into the gym.
- Find the Shop icon on the left side of the screen, or walk up to the Shop stand inside the gym.
- Open the Codes section inside the Shop.
- Type the code into the box exactly as written, including capital letters — codes are case sensitive.
- Press Redeem. A working code applies its reward straight away; a dead one gives an error and costs you nothing.
Codes that used to work
Kept on purpose. Most sites quietly delete dead codes, which is why you end up typing the same broken one three times — here you can see it is already gone.
Codes people are claiming, that we have not verified
Someone published these publicly; our own scan of the live game has not seen them. They are kept apart from the list above on purpose — everything above was observed in the game on the date shown, and nothing down here was. More detail on the code watch page.

How we check, and how often
Once a day an automated process reads the live game the same way a player would, and records every code it finds together with the date. A second sweep runs five times a day across YouTube, the community wiki and the developer's own channels, looking for any announced but not yet visible in the game itself.
Those two streams are kept apart on purpose. Anything on this page above was seen in the game itself. Anything only claimed elsewhere stays on the code watch page marked unverified until our own scan finds it. A code is never promoted because lots of sites repeat it — that is how a fake code spreads, not how it becomes real.
Why codes stop working
These are switched off by the developer, not by an expiry timer. A code usually dies for one of three reasons: it was tied to an event that ended, it hit a redemption cap, or an update replaced it with a new one. None of those give any warning, which is why a list without dates on it is worth very little.
That is also why expired codes stay visible on this page. If you already tried one and it failed, seeing it marked expired tells you the failure was the code and not your typing.
Common questions
Are Gym Star Simulator codes case sensitive?
Yes. Type them exactly as shown, capitals included. This is the single most common reason a code that is genuinely working returns an error, which is why every code on this page has a copy button instead of asking you to retype it.
Why do other sites list more codes than this one?
Because they keep dead codes on the page. We read the codes out of the live game once a day and record the date each one appears, so a code shown as working here was observably present on the date next to it. Ones that stopped appearing are moved down the page and marked expired rather than deleted, so you can see the one you already tried is dead.
Where do new Gym Star Simulator codes come from?
The developer releases them for updates and follower milestones, usually announced in the game itself and in the community channels. Our daily check reads them from the experience directly, so a new code shows up here without anyone having to spot the announcement.
Do pet multipliers add up or multiply together?
They add. Each equipped pet contributes its muscle growth multiplier to a combined total, which is why a handful of mid-tier pets can beat one rare one. Crafting three identical pets into a Shiny raises that contribution and adds a second enchant.
Is Gym Star Simulator still being updated?
Yes. The homepage shows the developer's last update time straight from Roblox, alongside our own daily player-count readings, so you can see for yourself whether the game is still moving rather than taking our word for it.
