Grand Piece Online is a Roblox action-RPG built around the One Piece universe, throwing players into open-sea exploration, boss fights, and Devil Fruit hunting. Codes for the game provide tangible shortcuts — time-limited drop rate multipliers, EXP boosts, and tailor vouchers that feed directly into character progression. They’re becoming increasingly rare, which makes each new release worth acting on fast.


Working GPO codes

  • FREE_Drops4 — 2x drop rate boost for three days NEW
  • FREE_EXP4 — 2x EXP boost for three days NEW
  • 5FREETAILORVOUCHERS_4 — five tailor vouchers NEW

Tip: Most GPO codes expire within 24 to 48 hours of release. Redeem any active code as soon as possible — the window can be very short.


How to redeem GPO codes

Launch Grand Piece Online on Roblox using the account you want to receive rewards on, then select the Set Sail option.
Press the M key on your keyboard to open the in-game menu.
Click the gear icon to open the Settings screen.
Click or tap the text field at the bottom of the Settings screen, then type or paste a working code into it.
Press Enter on your keyboard to submit the code. Your rewards will be added to your account immediately.

Tip: When pasting a code, there is often a stray trailing space at the end. A quick tap of the backspace key before hitting Enter usually resolves any “invalid code” errors. For codes that begin with a special character, typing them manually tends to be more reliable than pasting.


Where to find more GPO codes

The Grand Piece Online Discord server is where developer Grand Quest Games drops new codes first, typically in the #updates channel under the Game Info tab. Setting up notifications for that channel is worthwhile, though be prepared for a high volume of unrelated posts — code drops make up a small fraction of the activity there. One caveat: the server frequently hits capacity, so joining isn’t always possible on demand. The invite link appears at the bottom of the game’s Roblox page when a spot opens up.

As a passive bonus, playing any session between Friday and Sunday each week automatically doubles legendary fruit rates — no code needed for that one.
