How to Redeem a Nexon Game Card

Q: How do I redeem a Nexon Game Card?

Sign in at nexon.net, open the Buy NX page, choose Nexon Game Card as your payment method, enter the card’s PIN, then select how much NX to add and confirm. The NX is credited to your Nexon account balance.

Q: Where do I enter my Nexon Game Card PIN?

Inside the Buy NX flow, not in a standalone redeem box. Open Buy NX at nexon.net, continue to the payment step, select Nexon Game Card as the payment method, and enter the PIN there to convert the card to NX.

Q: What happened to Karma Koin?

Karma Koin was rebranded to Nexon Game Card in September 2022. Existing cards still work the same way — you add their value as NX through the Buy NX flow — and unused balance can still be combined at nexongamecard.com.

Q: Why won't my Nexon Game Card PIN work?

The most common cause is a retail card that wasn’t activated at purchase, since only the store can activate it. A mismatch between the card and your account’s country can also affect how the value converts. See the troubleshooting section above, or contact support with your order number for a digital card.

Q: What games can I use a Nexon Game Card for?

The NX you add works in Nexon titles like MapleStory, MapleStory M, Mabinogi, and Vindictus. The card is also accepted as a prepaid payment method across 20-plus partner publishers, including games such as World of Tanks, World of Warships, and Path of Exile.

Q: Can I combine Nexon Game Card balances?

Yes. Use the Combine Your Card Balance tool at nexongamecard.com and enter the PINs of two cards to merge their value, as long as the second card’s balance doesn’t exceed $500 or €400. This is handy when a card has leftover value after you’ve converted part of it to NX.

Add NX to your account through the Buy NX flow at nexon.net

A Nexon Game Card isn't entered in a redeem box — you add its PIN as a payment method inside the Buy NX flow to load NX onto your Nexon account. Here's the exact flow and what NX buys.

How to Redeem a Nexon Game Card

To redeem a Nexon Game Card, sign in at nexon.net, open the Buy NX page, choose Nexon Game Card as your payment method, then enter the card’s PIN and select how much NX to add. The NX lands in your Nexon account balance and is ready to spend in MapleStory and other Nexon games.

How to Add NX with a Nexon Game Card

A Nexon Game Card is redeemed in one place — the Buy NX flow at nexon.net, in any web browser. There’s no separate “redeem code” box: you select the card as a payment method and enter its PIN, which is the part most people get stuck on. The NX is added to the Nexon account you’re signed in to.

On the Web (Buy NX at nexon.net)

Use the account you actually play on, since the NX is tied to that Nexon account once it’s added.

Sign in to your Nexon account at nexon.net.
Open the Buy NX page from the top navigation or the Balance section of your account.
Continue to the payment step and choose Nexon Game Card as your payment method.
Enter the PIN from your Nexon Game Card.
Select the amount of NX to redeem, up to the card’s balance, and confirm to add it to your account.

If you can’t find a place to type the code, that’s expected — the PIN goes in the Nexon Game Card payment option inside Buy NX, not in a standalone redeem field.

What You Can Buy with NX and Your Nexon Game Card

NX is Nexon’s virtual currency. Once it’s on your account, you spend it on in-game items, character customization, and premium content in Nexon titles such as MapleStory, MapleStory M, Mabinogi, and Vindictus. You choose how much of the card’s value to convert to NX, so a single card can fund several purchases over time.

The Nexon Game Card — known as Karma Koin before its 2022 rebrand — is also accepted as a prepaid payment method across more than 20 partner publishers, including games like World of Tanks, World of Warships, and Path of Exile. Leftover value isn’t lost: you can merge cards with the Combine Your Card Balance tool at nexongamecard.com, as long as the second card’s balance doesn’t exceed $500 or €400.

Use it for: NX for MapleStory, Mabinogi, and Vindictus, plus prepaid payments across Nexon’s partner games.
Best match: a Nexon player who wants to add NX or pay for game content without putting a card on file.

Why Your Nexon Game Card Isn’t Working

Nexon Game Card problems usually trace back to activation, your account’s country, or the flow itself being different from a typical gift card. Work through the checks below before contacting support.

The PIN is rejected or the card isn’t activated

A retail Nexon Game Card has to be activated by the store at purchase, and Nexon can’t activate it afterward — an unactivated card returns a PIN error. If you bought a physical card, keep your receipt and contact the retailer. If you bought a digital card from MyGiftCardSupply and the PIN won’t take, contact MyGiftCardSupply support with your order number for a check or replacement.

Your account country doesn’t match the card

Your Nexon account’s Country Selection sets your currency and determines which games are available, and account country and billing location can affect sales tax and the final NX value. If the card and your account region don’t line up, the value may not convert as expected — redeem on an account whose country matches the card.

You can’t find a “redeem code” field

There isn’t one. Unlike most gift cards, a Nexon Game Card isn’t entered in a redeem box — the PIN is submitted as a payment method inside the Buy NX flow. Open Buy NX, choose Nexon Game Card at the payment step, and enter the PIN there.

There’s leftover balance on the card

If you only converted part of a card to NX, the remaining value stays on the card. Use the Combine Your Card Balance tool at nexongamecard.com to merge it with another Nexon Game Card — enter both PINs to consolidate, provided the second card’s balance is at or below $500 / €400.

Get More NX with Another Nexon Game Card

Players come back for another Nexon Game Card when their NX runs low, when they want to top up without a credit card on file, or when a foreign payment method is being declined at checkout. Because the card adds NX directly through the Buy NX flow, it’s a clean way to keep funding MapleStory and other Nexon games.
