GPO codes can be a great way to boost an existing character or avoid the early grind of training up a new one. They’re rare and don’t drop too often, so you’ll want to be quick to redeem them.
Grand Piece Online is a Roblox experience wholly (and entirely unofficially) based on the One Piece anime. It’s another that’s been sending us on high-seas adventures for years now. New codes for Grand Piece Online give free race rerolls, 2x drop rates, and more and typically drop on the game’s Discord.

How to get more Grand Piece Online codes
New codes for GPO are added to the Grand Piece Online Discord server as soon as they’re available. The GPO Trello has a card for codes, but it hasn’t been updated in a long while
If you don’t mind some nonsense notifications between the rare code drops, that’s where you’ll want to be. The GPO Twitter account has been inactive for a while.
Alternatively, you could let us do the work for you and check back on this page every day instead – we’ll update it as and when new codes arrive.
If you’re just after more rerolls, here are a few developer-suggested ways to get them:
When is the next GPO update?
Mini Update 2 landed at the very start of April 2024. It wasn’t even an April Fools joke. It featured the Abyssal Karate Fishman 2 fighting style.
While the date for the next update hasn’t been set, the developers have outlined that it’s likely to bring GPO to mobile platforms. They even made a new code to celebrate.
Is there an official GPO Trello link?
Yes, the Grand Piece Online Trello link was recently overhauled to match Update 10 of the game.
That means it should now be an invaluable resource, showing you where to find new NPCs for the patch, bosses to tackle, and powerups to seek on.
What time do Mihawk and Roger spawn?
