How to redeem codes

To redeem codes in Katana Simulator, look for the Codes button or Twitter bird icon in the game's UI sidebar. Click it to open the code input panel, type your code, and confirm. Codes appear to be case-insensitive based on the mix of formatting seen in released codes. Each code is one-time use per account.

Codes reward Coins (the primary currency used to buy sword upgrades) and 2x Coins Boosts that temporarily double your earnings. The 2x Coins Boost is the most valuable reward - it directly accelerates your progress through the katana upgrade ladder for its duration. One cosmetic item, a Space Helmet, has also been awarded through a code.

Katana Simulator codes have historically been tied to community milestones and update announcements - milestone names like 75KTHANKS and thanksfor65k reflect this pattern. The game's last significant update was March 2023, so new codes are infrequent. The Paragon developer group's Twitter/X account is the primary source for any future releases.
