# Redeem and open NFT card case (bonus card case)

### 1. Redeem NFT card cases (bonus card cases)

In the ShopNEXT ecosystem, new NFT card cases can be redeemed only when users earn enough NEXT from their shopping activities. **Deposited NEXTs cannot be used to redeem new NFT card cases.**

There will be 4 card case levels for redemption . The higher the card case level, the higher chance to earn the rarer cards.

* Card case level 1: <mark style="color:purple;">**1000 NEXT**</mark>&#x20;
* Card case level 2: <mark style="color:purple;">**2000 NEXT**</mark>&#x20;
* Card case level 3: <mark style="color:purple;">**3000 NEXT**</mark>&#x20;
* Card case level 4: <mark style="color:purple;">**4000 NEXT**</mark>

It is not a must to start to redeem Card case level 1. As long as users can accumulate enough NEXT, they can redeem at any Card case levels.

{% hint style="info" %}
You're also able to accumulate a minimum of **3000 NEXT** in your Earning Balance to exchange for phone prepaid cards, shopping vouchers, or to cash out.
{% endhint %}

### 2. Open NFT card cases (bonus card cases)

After redemption, you can open NFT card cases to see the details of [NFT cards](/whitepaper/how-to-play/what-are-nft-cards-bonus-cards.md). Depending on the card case level and average karma, users will have different possibility of receiving different card types and categories in opening.

Karma will be used to determine the probability of earning the high level NFT cards. The probability to open a particular NFT card category will be divided equally to the total number of card categories.

### *Opening when average karma of the account is below 50*
