Project Iron Codes

The rewards from Project Iron codes are Rerolls and timed boosts. Rerolls let you roll again, and the rolling system the official description highlights is genetics: it invites you to roll genetics and become the biggest you possibly can. REROLLS gives 50 in every category, so you can try several rolls before you settle on a build.

The boosts from SORRY last 20 minutes and stack three effects: 20% more muscle and strength gains, 25% more money and 10% more luck. Because they run on a timer, redeem SORRY when you are ready to train hard, not right before you log off. Destructoid lists the same reward for ZINO, but PCGamesN does not give an amount for it, so check what you receive.

Project: Iron is a Roblox fitness game from Irongrid Games, released in September 2026, and the current version is tagged V2.6: Expansion. It aims for realism more than most gym games on Roblox. According to the official description, you can:

• Build muscle and strength with 22 exercises that train 62 different muscles.
• Win bodybuilding shows or powerlifting meets against other players or NPCs.
• Share photos on a built-in social media app and earn money from followers.
• Spend that money on cars, equipment and supplements that boost your progress.
• Train speed and run the track to test your times.
• Roll genetics and become an elite powerlifter or an Olympia-level bodybuilder.

That mix of a realistic muscle system, competitions and a social media side game is what sets it apart. When we checked on October 25, around 2,200 players were in the game at once.

If the box rejects one of the codes above, check these things:

• Already redeemed: PCGamesN notes that a code you have already claimed will not pay out again.
• Spelling: type codes exactly in capitals, or copy them with the button.
• Older codes: EXPANSION, OPTIMIZATION and ARMWRESTLING may already be switched off. Try the four official codes first.
• Expired codes: TARNISHED no longer works, according to both PCGamesN and Destructoid.

So far, codes have arrived with updates and apologies. EXPANSION matches the V2.6 Expansion update, OPTIMIZATION and ARMWRESTLING appear to match earlier patches, and SORRY reads like a make-good after a problem. The developers also put the current codes straight into the game description, which makes it the most reliable place to check.

Irongrid Games runs a Discord for the game, but the invite Destructoid links has expired, so we do not list it here. The Roblox game page and its description are the official source until a permanent invite is available. We check both whenever the game updates and add new codes here once they are confirmed.

If you are just starting, the codes give you a strong head start. Here is a simple order to use them in:

• Redeem REROLLS first and roll your genetics, since they shape everything that follows.
• Redeem SORRY and ZINO when you are about to start a long training session so the boosts are not wasted.
• Use the money boost to save for equipment and supplements, which the description says boost your progress.
• Try a powerlifting meet or bodybuilding show against NPCs before you take on other players.

Project: Iron is still a young game. It went live on September 4, 2026, and when we checked on October 25 it had about 657,000 visits, around 2,100 players online at once and about 5,600 favorites, with roughly 1,790 likes against 230 dislikes. Each server holds up to 20 players, and the last update arrived on October 24, 2026.

One habit makes this game easier to follow than most: the developers print the current Project Iron codes in the game description itself. You can check them on the Roblox page before you even open the game, and if a code disappears from the description, treat it as retired. We compare the description with the code trackers each time we update this page.

We check Project Iron codes by hand. A code goes into the main table only when at least two independent sources agree on it, or when it comes straight from the official game description or rules. Codes that only one source reports, or that sources disagree on, are kept in a separate unconfirmed table, so you can still try them without mistaking them for confirmed codes. A code moves to the expired list once it is reported as no longer working.

This page was last checked on October 25, 2026. We never make up codes or rewards, and we keep a list of the sources behind every code. If something on this page no longer matches what you see in the game, tell us with the Feedback button and we will check it again.

Every code is listed exactly the way the game expects it, with the same capital letters, numbers and symbols, so the safest way to enter one is the Copy button next to it rather than typing it by hand. A code that turns out to be wrong is moved to the right table, never silently deleted.
