[CUPID] Grand Piece Online Codes 2026 – Free XP

If you’re sailing the seas in Grand Piece Online, redeeming codes is one of the easiest ways to get useful boosts, rerolls, and resets. With the Cupid Event update, several new codes have been released that grant 72 hours of 2× EXP and 2× drop rates, making it the perfect time to grind the Cupid Dungeon or farm rare items.

Below is the updated list of working GPO codes for March 2026.

These two codes were released alongside the Cupid Dungeon update and are currently the most valuable codes available.

These codes are still working and can give players race rerolls, stat resets, drop boosts, and other rewards.

These codes no longer work:

• 1BILLIONVISTS2XDROP

• 1BILLIONVISTS2XEXP

• 1BILLIONVISTS10RACEREROLLS

• 5FREEROLLSYAY

Redeeming codes in GPO only takes a few seconds:

• Open Grand Piece Online in Roblox.

• Press M to open the game menu.

• Click on the Shop tab.

• Paste one of the codes into the code entry box.

• Press Enter to claim your reward.

New codes are usually released through the official Grand Quest Games Discord server or alongside major updates and events. Developers often release codes to celebrate milestones, holidays, or large patches.

Bookmarking a code list is also useful, since it’s updated whenever new codes appear.
