Update: Checked for new Mongil: Star Dive codes on May 29, 2026.
Mongil: Star Dive is an action RPG by Netmarble set in Belana, a world where players build a team of three characters, swap between them mid-battle to chain skills, and fill out a Monster Codex by taming creatures called Monsterlings. The gacha-driven progression system rewards active players with new Companions and equipment, and redemption codes add a free layer on top — handing out Monsterlings, Starlight Crystals, Gold, and upgrade materials without pulling from the gacha pool.

How to redeem codes in Mongil: Star Dive
There are two ways to redeem codes — through the in-game settings menu or via Netmarble's browser-based redemption page. The in-game route is quicker on Android and PC. iOS players should use the website method, as the in-game redemption input does not reliably appear on that platform.
In-game redemption
Step 1: Open Mongil: Star Dive and tap the menu button in the top-right corner of the screen. A sidebar will slide in from the right.
Step 2: Tap the cog icon to open Settings, then select the Other tab at the top of the settings panel.
Step 3: Scroll down to the Customer Support section and tap Redemption Code. A text entry window will open over the screen.
Step 4: Type or paste your code into the field and tap Use. A confirmation message appears when the code is accepted.
Step 5: Close settings and tap the envelope icon in the top-right sidebar to open your Mail. Select the reward message and tap Claim to collect the items.
Note: The Mail inbox becomes available after completing the introductory main quest, Monster Tamers.
Website redemption
Step 1: In the game, open Settings, go to the Other tab, and copy your Player ID. This acts as your Member Code on the redemption site — the Friend Code is a separate field and will not work here.
Step 2: Visit the official Mongil: Star Dive code redemption page. Paste your Player ID into the Member Code field, then enter a working code in the Coupon Code field below it.
Step 3: Click Use. The reward will appear in your in-game Mail. Return to the app, open the Mail tab from the sidebar, and tap Claim on the redemption reward message.
Where to find more codes
Netmarble releases new codes without a set schedule. They tend to appear around major updates, developer livestreams, and character reveal events, with the official Mongil: Star Dive Discord server being the most common place they are first announced. The game's social channels are also worth monitoring. Since no fixed cadence exists, checking back here regularly remains the most reliable way to catch active codes before they expire.
