How to Get Free Gems in ONE PIECE Bounty Rush

In ONE PIECE Bounty Rush, Rainbow Diamonds (often simply called 'gems' by the community) are the game's premium currency: they're used for recruitment scouts to unlock characters, each pull costs 50 Rainbow Diamonds, and the odds of pulling a top-tier character sit around 0.2%, so it takes thousands of them to build a competitive roster. Unlike other gacha titles, OPBR doesn't hand out this currency generously: the community and several guides describe it as a resource that 'doesn't come easily' and is best saved for banners featuring powerful or limited-time characters. This guide compiles the real, verified methods for getting Rainbow Diamonds without paying: daily missions, the Events section (which refreshes monthly), progress through Story mode, redeem codes, and the free monthly claim on Bandai Namco's official website. We also cover what doesn't work (generators, hacks) and what to realistically expect in terms of quantity if you play for free.

What's the fastest way to get Gems in ONE PIECE Bounty Rush?

We've gathered and verified every real method for getting free Gems, ranked from most to least profitable based on the time they take and what you can actually earn from each. No tricks, no generators — just the game's own mechanics.

Variable (small amounts per mission) Daily

Daily missions

The daily missions section is, according to several guides, the most consistent source of free resources, including Rainbow Diamonds. It's recommended to check and complete every assigned mission, especially the ones marked as hard, since they tend to reward better. No source consulted offers an official, reliable figure per mission, so treat it as a small but steady income rather than a fixed amount.

Variable Daily

Login rewards

The game rewards you simply for logging in each day, handing out resources that include Rainbow Diamonds, character fragments, upgrade materials, and battle points. There's no exact published amount, but it's a free habit that costs nothing to keep up.

Variable Monthly

Events section

The Events section works as a mission hub that refreshes roughly every month. Completing these special missions is another route cited by player guides for building up Rainbow Diamonds, along with other materials. Since it's rotating content, it's worth checking often so you don't leave rewards unclaimed.

One-time rewards per chapter One-time

Story mode progress

Progressing through Story mode chapters, which follows the One Piece plot, delivers one-time rewards that can include Rainbow Diamonds along with Bounty coins and materials. These are one-off, not recurring, rewards, but they add up especially in the first few weeks of play.

Variable Daily

PvP battles (League Battle and Challenge Battle)

Winning matches in the 4-vs-4 team combat modes (League Battle and Challenge Battle) can bring extra rewards, according to the community. No concrete Rainbow Diamond figures per win have been found, so treat this method as an extra tied to your skill level, not a guaranteed source.

5 Rainbow Diamonds Monthly

Free monthly claim on the Bandai Namco website

Bandai Namco Entertainment lets you claim 5 Rainbow Diamonds for free every month through its official web store by linking your game account. It's a small but fixed, guaranteed amount at no cost, and it's worth putting on your calendar so you don't forget it.

~5 Rainbow Diamonds per code Variable

Redeem codes

Bandai Namco occasionally publishes redeemable promo codes (for example the code '2026,' active until 08/02/2026, which gave 5 Rainbow Diamonds) through a redeem website linked to your Bandai Namco account. Previous codes (RUSH, BOUNTY, SEVEN, EGGHEAD) have already expired, which confirms they're refreshed over time. It's worth following the game's official social accounts so you don't miss new ones.

How much free Gems can you get per month?

Source	Estimated amount	Frequency
Monthly claim (Bandai Namco website)	5	Monthly
Redeem codes	~5–10 (approx. 1-2 codes a month)	Variable
Estimated total	~10–15 Rainbow Diamonds per month (confirmed-figure sources only)	—

This figure is a minimal, conservative estimate based only on the two sources with a confirmed amount (the monthly web claim and redeem codes); it doesn't include daily missions, events, Story mode, or PvP, which also grant Rainbow Diamonds but without official or reliable published figures. In practice, playing daily and completing missions and events adds up to noticeably more, but no guide consulted offers a verifiable figure for those sources, so we'd rather not make numbers up.

Frequently asked questions

Are 'gems' and Rainbow Diamonds the same thing in One Piece Bounty Rush?

Yes. The game doesn't officially use the word 'gems'; its premium currency is called Rainbow Diamonds, but much of the community and YouTube searches call them 'gems' out of habit, just like in other gacha games.

How much does a recruitment scout cost, and is it worth saving up Rainbow Diamonds?

Each recruitment pull costs 50 Rainbow Diamonds, and the odds of getting the highest-tier characters sit around 0.2%. Given how little you earn for free, most guides recommend saving up and only spending on banners featuring characters you genuinely want, rather than pulling impulsively.

Do generators or hacks for unlimited free Rainbow Diamonds exist?

No. There are websites and videos floating around promising 'hacks' or unlimited diamond generators, but there's no legitimate method of that kind: they're usually phishing scams or account theft attempts. The only real methods are the ones inside the game (missions, events, login) and Bandai Namco's official channels (redeem codes and the web claim).
