How to get free Diamonds in Mobile Legends: Bang Bang

Diamonds are the Mobile Legends game’s premium currency.

Most players pay for them, but there are legitimate, no-cash ways to get small amounts.

Below, you’ll find only verified options tied to official MLBB systems, reputable programs, and clear instructions to avoid scams.

Mobile Legends: Bang Bang (MLBB)

It is a free-to-play mobile MOBA (multiplayer online battle arena) developed and published by Moonton Games.

The game launched in July 2016 and is available on Android and iOS (also playable on iPadOS/HarmonyOS).

Core matches are 5-v-5, played on a three-lane map with towers, jungle objectives, and distinct hero roles.

What Diamonds Are (and why “free” is limited)

Diamonds unlock premium skins, heroes, and event draws. Moonton, MLBB’s publisher, distributes Diamonds primarily through purchases.

However, the company also runs time-limited events and contests where Diamonds are part of the prize pool.

It operates an official redemption site for codes shared via official channels.

Expect modest quantities and irregular availability; be wary of any tool promising unlimited Diamonds.

Method 1: Join Official MLBB Events that award Diamonds

Moonton regularly hosts global or regional events with Diamond rewards.

Examples in 2025 include official creation contests and community activations with clear rules, published on MLBB’s event microsites.

These pages explicitly list Diamond prize tiers, often alongside cosmetics and merchandise.

Track these pages around major moments (anniversaries, hero releases, seasonal campaigns).

Where to look

MLBB event hubs (e.g., Points Milestones campaign shows “10,000 Diamonds” among prizes).
Project NEXT Creation Contest (GLOBAL) with stated Diamond rewards for winners.
New-Hero content contests (e.g., Zetian UGC Contest) that mention cash and Diamond prizes.

How to approach

Read eligibility, deadlines, and submission formats carefully. Contest Diamonds go to selected participants; they are not guaranteed to every entrant.

Method 2: Use Official Redeem Codes (from verified sources only)

Moonton sometimes distributes limited-time redeem codes via official channels (campaigns, esports broadcasts, partner promotions).

Codes can grant various items and, occasionally, Diamonds.

Go to the official MLBB redeem page.
Enter your Game ID and the code, tap Send to receive a verification code in your in-game mailbox.
Enter the verification code and redeem; rewards arrive via in-game mail.
The process is identical to the instructions Moonton has posted on its social accounts and summarized by reputable guides.

Tips that keep you safe

Ignore “code generators” and sites that ask for your password.

Codes expire and may have regional or quantity limits, so redemption is not guaranteed even if the code is authentic.

Method 3: Pay $0 out of pocket using Google Opinion Rewards credits

If you’re on Android, Google Opinion Rewards occasionally grants Play Store credits in exchange for short surveys.

Those credits are valid for in-app purchases, which means you can fund a Diamond buy without spending your own money.

Google explains how to redeem credits directly in Google Play; once credited, you can use them on in-app purchases like MLBB Diamonds.

Caveats: survey frequency and value vary by region and user profile; this isn’t instant or guaranteed. Credits also expire if unused.

Method 4: Participate in the MLBB Creator Camp (for creators)

Moonton runs a Creator Camp to promote community content. The program’s official portal lists creator resources and activities.

Third-party coverage of the program notes that qualified creators can receive Diamonds among their rewards.

Always confirm the current reward structure on the official portal before you start.

Who this suits: players who already make short videos, guides, or highlights and can follow content briefs during specific campaigns.

Method 5: Watch for anniversary & seasonal promos (including Promo Diamonds)

During large campaigns (e.g., anniversary, ALLSTAR, Double 11), MLBB commonly runs missions, log-ins, and mini-events that yield rewards.

Some events distribute Promo Diamonds, a special discount currency that reduces the Diamond cost of certain purchases (you still pay at least 1 real Diamond).

While Promo Diamonds aren’t the same as free Diamonds, they effectively cut the amount you need to spend.

Track official news and event pages during these windows.

(Community wikis and videos discuss how Promo Diamonds work; treat those as explanatory references only and verify against the current in-game rules.)

What doesn’t work (and what to avoid)

Generators, mod APKs, and “unlimited Diamonds” tools: these are scams or violations that risk your account.

If a site posts dozens of evergreen codes, most are recycled or expired. Only the official redeem center and messages from verified MLBB channels are authoritative.

If you decide to buy, use in-game purchases or Moonton-listed payment partners by region (e.g., the official payment methods page).

These aren’t “free,” but they are safe and sometimes include bonus Diamonds during promotions.

How to maximize your chances (practical routine)

Follow official channels weekly around major patches and esports events. Codes and contests often drop then. Use push notifications where available.

Check the event hub from time to time; contests and mini-events rotate and may show Diamond prizes explicitly.

If you’re on Android, run Google Opinion Rewards, answer surveys when they appear, and apply credits to MLBB purchases before they expire.

If you create content, review current Creator Camp opportunities and requirements; rewards (including Diamonds) depend on the specific campaign.

Quick FAQ

Are there permanent, repeatable ways to farm Diamonds for free?

No. Free Diamonds are event-bound or campaign-specific. The only ongoing “no cash” route is covering purchases with Google Play credits earned from surveys, which depends on availability in your region.

Do redeem codes always give Diamonds?

No. Codes can grant many items; some campaigns include Diamonds, many do not. Always verify the code’s source and validity window. Redeem only through the official site.

What are Promo Diamonds—are they free Diamonds?

Promo Diamonds are discount currency from special events; they reduce the Diamond price of designated items but usually require at least 1 paid Diamond to complete the purchase. They help you spend less, not nothing.
