Codes are codes. Codes usually award variations of Coins, Crates, Eggs or Skins. Codes are usually found on Isaac's Twitter or in advertisements on the Roblox website.
To redeem a code, click the button on the left side of the screen labeled Codes (with a Twitter icon). Input the code into the text box that appears and press the Enter button to confirm.
Codes are not case-sensitive (meaning capitalization does not matter).
Note: Codes may expire. We'll try to keep this list updated as new updates come.
Key: Bold = Requires account to be 5 days or older to redeem.
