How to redeem codes

To redeem codes in Build Your Train, click the Settings Cog (gear icon) in the top left of the screen. Enter your code in the "Code Here..." text box and click the green submit button. Codes are case-sensitive, so enter them exactly as shown including any underscores and mixed capitalization.

Codes reward train parts like Better Wheels and Freebies (part bundles), Cool Stars (seasonal items for exclusive cosmetics), and occasionally Cash. Better Wheels from the freewheels code directly improve your train's speed and earning efficiency - priority parts in the early game that would otherwise take time to grind for. Cool Stars from update codes like BLIZZARD25 unlock cosmetics not available through normal play.

Code releases follow the monthly update cadence - named update codes (OCEAN, BLIZZARD25, DECORATIONS) dropped alongside each content release. New codes are announced through the Evil Interest Discord (discord.gg/9fhanC6kzK) and in the game description. Joining the Evil Interest Roblox group also grants special in-game rewards.
