New codes are typically added every 3 days. This timeline usually correlates to when the developer releases new updates to the game.

A code might not work for several reasons:

• You have already used the code (each code may only be used once per person).

• You are in an outdated version of the game (close the game, reopen it, and try again).

• The code is expired (let us know by flagging the code).

New codes are announced on the Merge a Black Hole Discord server. Join Discord and look for the announcements, updates, or codes channels. Codes are also sometimes posted on the developers' social media channels, such as YouTube and X. You can follow the developers on those platforms to monitor for new codes, or you can bookmark this page and tap the notification bell at the top of this page to be alerted as soon as a new code releases.
