Try them at the in-game mailbox and treat each result as platform- and date-specific rather than assuming every announced code is still active.
Announced and reported Cassette Beasts codes
Bytten Studio’s announcement archive records these codes and rewards. The posts establish that the codes were announced, not that they remain valid now; they do not provide expiry dates or current redemption results.

Bytten Studio’s anniversary zine announcement refers to a new mailbox giveaway code but does not print its value in the reviewed text. The value ANNIVERSARY3 comes from community reports, so regard it as a reported code rather than an officially confirmed one unless it is verified in-game or in a primary announcement. See the official archive and Steam community reports.

How to redeem a mailbox code

- Interact with the mailbox and enter the code exactly as shown, including its letters and numbers.
- Submit it and check the on-screen response or your in-game items to see whether it was accepted.
Bytten Studio’s code announcements direct players to enter codes at the mailbox in the game. The reviewed sources do not establish extra account or purchase requirements. No physical item is needed to redeem a code.

Do the codes work on PC, Switch, and Xbox?
The game’s official page lists Steam, Xbox One, Xbox Series X|S, Xbox Game Pass, and Nintendo Switch. The official wiki also lists Windows and Linux on Steam. Those platform listings do not establish that mailbox codes work identically on every platform.
Community reports describe different redemption outcomes by platform and date, including reports involving Steam Deck. These are not controlled tests, so a report from another player cannot guarantee the result on your copy. Try a code in your own game and, when sharing the result, include the platform and date you tested it.

Why the October 2026 list is not confirmed as “all working”
The announcements confirm past promotions, not live validity. The official posts reviewed provide no expiry dates or current test results, and the community reports do not settle which codes still work across platforms as of October 2026. For that reason, this is a list of announced and reported codes to try—not a verified list of every active code.
The 1MILLION announcement coincided with Bytten Studio reporting that the game had sold over 1.1 million units across all platforms in 2025. That figure was reported by the developer, not independently audited. The game itself is an open-world, turn-based RPG built around recording monster forms to tape, battling, exploring, and fusing forms.
