If you are a Mobile Legends: Bang Bang (MLBB) player, you know the struggle: the perfect skin drops in the shop or a massive Diamond Promo Event starts, and your diamond balance is sitting at zero.
While premium diamonds are Moonton’s primary currency, you do not need to spend real money to get them. There are legitimate, official ways to farm free diamonds, diamond vouchers, and event tokens to buy the skins you want.
In this guide, we’ll break down the best legit methods to get free MLBB diamonds for the latest promo events—and how to avoid the fake “diamond generator” scams that will only get your account banned.
What Is the Promo Diamond Event?
The Promo Diamond Carnival is an official MLBB event where players earn a special currency called Promo Diamonds by completing daily in-game tasks, then use them during a limited “Mega Sale” window to buy skins and cosmetics at steep discounts — sometimes for as little as 1 regular Diamond.
It’s one of Moonton’s biggest recurring promotions, and it typically runs in two phases: a collection phase where you rack up Promo Diamonds through simple daily activity, and a shorter spending phase where those Promo Diamonds get applied automatically at checkout in the in-game shop.
The Catch: Why “Free” Diamonds Still Need 1 Diamond
Here’s the part that trips a lot of players up, and honestly the reason so many “free diamond” scam sites exist in the first place: Promo Diamonds are a discount currency, not a standalone currency. To redeem a skin using Promo Diamonds, your account still needs at least 1 regular Diamond in your balance at checkout — the Promo Diamonds cover the rest of the cost, but the system won’t let the final price hit exactly $0.
If you’re a free-to-play player with zero Diamonds, this means grinding Promo Diamonds alone won’t get you a skin — you’ll also need to top up at least 1 Diamond (the cheapest top-up tier), which usually costs less than a dollar in most regions. This is a real limitation of the event, and any site claiming to hand out “free diamonds” that bypass this requirement is not describing how the actual event works.
1. Participate in Official In-Game Events
Moonton frequently hosts in-game events tied to holidays, game anniversaries, or new hero launches. These are the most reliable ways to get free premium currency.
- Event Token Shops: During major promo events, you can earn special event tokens by playing matches, completing daily quests, or logging in. These tokens can often be exchanged in the event shop for Diamond Vouchers or direct diamond packs.
- Lucky Box & Spin Events: Keep an eye on the “Events” tab. Moonton often gives out free spins or lucky boxes that contain diamond fragments or basic chests, which can add up over time.
- Login Milestones: Simply logging in during a promotional week can reward you with diamonds or starlight membership trial cards, which give you a massive boost in in-game currency.
2. Watch Official Esports (MPL & M-World)
If you love watching professional Mobile Legends, you can literally get paid in rewards to do it.
- In-Game Esports Tab: During major tournaments like the MPL (Mobile Legends Professional League) or the M-World Championship, Moonton hosts in-game watch parties.
- Predict and Cheer: By logging into the Esports tab, predicting match winners, and cheering for your favorite teams, you earn esports coins. These coins can be redeemed in the Esports shop for diamonds, exclusive skins, and recall effects.
3. Join the MLBB Advanced Server
If you are a dedicated player who wants to test new heroes, balance changes, and skins before the rest of the world, apply for the MLBB Advanced Server.
- How it works: Moonton opens applications for the Advanced Server a few weeks before a major patch.
- The Reward: If you are accepted, play matches, and submit valid bug reports or feedback, Moonton rewards you with ** Diamonds and exclusive Advanced Server skins** that you can bring back to the main server.
4. Redeem Official Moonton Promo Codes
Occasionally, Moonton releases official alphanumeric redeem codes during live streams, anniversaries, or special announcements.
- Where to find them: Always check the official Mobile Legends Bang Bang Facebook page, Instagram, or their official YouTube live streams.
- How to redeem: Go to your in-game Profile > Click the “Redeem Code” button (usually under the settings or profile menu) > Enter the code.
