Project Iron Codes (October 2026)
Project Iron codes pay out Rerolls across all categories, and when you are chasing a better genetic roll, stacking up 50 of them at once changes everything. That is the whole game in a nutshell: build the biggest, strongest version of you possible.
It is a gym grind sim through and through, with 22 unique exercises, a pile of individual muscles to develop, and bodybuilding shows and powerlifting meets to win against other players or NPCs. You can buy supplements and equipment to speed up progress, train your speed on the track, flex your physique on the built-in social media app for cash, and then blow that money on cars. Rerolls are the currency of the perfectionists, letting you take another swing at your height, weight, frame, and genes until the numbers line up right. Batches of 15 and 35 show up too, so there is plenty to claim.
Punch them in while they still work, because these do get retired. Here is every code currently working.
Quick Answer: That’s 4 active codes up for grabs in Project Iron right now. Codes are case-sensitive, so copying beats retyping.
The newest working code is REROLLS. Expired Project Iron codes remain below for reference.

Where to Find More Project Iron Codes
The Project Iron Discord server is where fresh codes tend to surface before anywhere else, straight from Irongrid Games. Most of them land around updates, or when the game crosses some milestone like a visit count or like goal, the kind of thing that gets announced and then rewarded a few hours later. It’s also worth hanging around for the usual chatter about what’s coming next, events, and the occasional giveaway. If sifting through announcement channels isn’t your idea of a good time, this page gets refreshed daily with everything currently working.
