How to redeem codes

To redeem codes in Karate!, open the code redemption interface in-game through the menu or a dedicated codes button. Enter the code exactly as written and submit.

Codes reward Yen (the primary in-game currency), flat EXP amounts, and timed 2x EXP boosts. Yen codes have ranged in value, and EXP boost codes typically grant one to two hours of doubled experience - these stack with the automatic weekend Double EXP event for maximum grinding efficiency. The most impactful use of boost codes is saving them for weekend sessions when the automatic 2x EXP is already active.

Karate! has released over 65 codes since its February 2021 launch, tied to maintenance events, holidays, anniversaries, and combat balance patches. Code names like BACKONLINE, PATCHEDUP, and YUMMYXP reflect this pattern. New codes are announced through the in-game description and the official community Discord server linked on the game page.
