Are you ready to explore caves, mine blocks, and claim rewards? Let's dive into the **Crystal Caves opBNB Summit** together and uncover its treasures!

## Step 1: Get BNB Token for Gas

To participate in the ***Crystal Caves on opBNB Network***, we suggest your wallet should have at least 0.0001 BNB to cover on-chain transaction fees. Here are two ways to obtain BNB token:

1. Use a bridge to convert BNB from ***BNB Smart Chain*** to ***opBNB Chain***: [opBNB Bridging](https://opbnb-bridge.bnbchain.org/deposit)
2. Withdraw BNB from a centralized exchange (CEX): [BNB Markets](https://coinmarketcap.com/currencies/bnb/)

{% hint style="info" %}
Please check if the CEX supports withdrawing BNB to ***opBNB Chain*** first
{% endhint %}

## Step 2: Start Exploring Crystal Caves

You are ready to explore the **opBNB Summit Cave**! Embark on your mining adventure to earn more rewards!

**Discover Crystal Caves**\
In the Crystal Caves, players navigate through cave environments, mining blocks to uncover valuable resources. Mining occurs directly on your device and is validated on-chain through smart contract transactions, ensuring transparency and security. Your goal is to mine as many valuable blocks as possible to earn USDT, Lumens, and Points.

**Step 2. Mining Blocks in Crystal Caves**

In **Crystal Caves**, players can explore the cave environment, mine blocks, and uncover valuable rewards like USDT, Lumens, and Points. The mining process takes place on your device and is verified on-chain, ensuring secure and transparent gameplay.

**How to Mine Blocks**

To start mining, follow these steps:

1. Double-click any adjacent block to mine it directly or select an adjacent block and click "Mine".<br>

   <figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FbEuHqpPONmTcJLXfsQyu%2Fcommon_game.png?alt=media&#x26;token=5033a15c-3143-4e1a-a20c-91296ac6bdc8" alt=""><figcaption></figcaption></figure>

* Players can mine up to **8 blocks** at a time. After 8 blocks, a **roll-up transaction** syncs the data on-chain and distributes rewards.
* Energy available (max 1000 blocks every 24 hours) is displayed at the bottom left corner for tracking.

2. When you’ve mined 8 blocks, the **Chest** turns golden. The game will triggers **Roll Up** to sync your progress, then **Confirm** the transaction in your wallet.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FtCcUPjzEvcTj4lH6FBQ0%2Fcommon_tx_metamask.png?alt=media&#x26;token=c8e9ec25-10e5-4fb6-9f57-82071aef5cd2" alt=""><figcaption></figcaption></figure>

3\. Once confirmed, a **Rewards modal** will pop up displaying all rewards from the roll-up. Click "**OK**" to continue. Check the **Reward Distribution** section in this guide for more details on rewards.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2Fsrj1H6Sv87M7k4XIeHNo%2Fopbnb_reward_blocks.png?alt=media&#x26;token=c635c552-e308-4ac1-9a31-61e57afab113" alt=""><figcaption></figcaption></figure>

4. Repeat this process as much as possible. The more blocks you mine, the more rewards you earn!<br>

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FsGbXY68eyDmX99P4JgR2%2Fopbnb_reward_results.png?alt=media&#x26;token=8c3880cc-e315-41ac-8117-2e2ef9016b8a" alt=""><figcaption></figcaption></figure>

**Step 3: Withdraw Your USDT Rewards**

If you have earned USDT rewards during the mining process, you will need to withdraw them manually. **Click on the "Claim" button** next to the reward to verify the amount and withdraw your rewards.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FhCxTsffHC9VVBoHhQKFS%2FSnipaste_2025-01-13_15-02-26.png?alt=media&#x26;token=f8e1f83e-e5fa-4726-97d0-44cc5cc631c3" alt=""><figcaption></figcaption></figure>

USDT on ***opBNB Chain*** is an officially bridged token ([blockchain explorer](https://opbnb.bscscan.com/token/0x9e5aac1ba1a2e6aed6b32689dfcf62a509ca96f3)). To transfer it to ***BNB Smart Chain***, you can use the [official bridge](https://opbnb-bridge.bnbchain.org/withdraw).&#x20;

**Experiencing Block Issues?**

Your local client (browser) might have temporarily lost sync with the blockchain. To fix this, we've added a feature to reset your local data without affecting your rewards—they’ll remain safely stored in the system.

**Here's How to Fix It:**

1. Click the **Settings** icon in the top right corner.
2. Select **RESET** and then confirm.

That’s it! You’re back on track.

## Step 3: Learn More about Pattern Matching (NEW) <a href="#reward-distribution" id="reward-distribution"></a>

In the ***Crystal Caves on opBNB***, we have introduced a pattern matching mechanism, which allows players to earn additional rewards by following specific block sequences. To ensure a better gameplay experience, we have also increased the mining pool size to **20x20**, which is 4 times larger than before.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2Fjujbd2LOVbMaqj22kHSe%2Fcommon_pattern_matching.png?alt=media&#x26;token=808014d5-b51c-4082-916e-a8c71f5d8a3e" alt=""><figcaption></figcaption></figure>

### Pattern Matching Rules <a href="#how-to-play" id="how-to-play"></a>

The game interface now displays **a sequence of 8 block types** that players should follow to mine blocks. **Blocks marked with a green check** indicate those that have already been mined but are yet to be rolled up. **The highlighted block** shows the next block type to be mined.&#x20;

To successfully complete a combo, players must mine the blocks in the correct order. When the combo is completed, the current sequence ends and a new combo will begin, with the "next" sequence becoming the current one.&#x20;

However, if players mine the blocks in the wrong order, both the current and next sequences will be **reset**.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FFNyBjb8NyLATnOd3t7EA%2Fimage.png?alt=media&#x26;token=a682ac7d-9ae3-42fb-aac2-4198964fd191" alt=""><figcaption></figcaption></figure>

### Roll up <a href="#how-to-play" id="how-to-play"></a>

The roll-up process is now **automatic if you complete a sequence**. As soon as players complete the current sequence, it will begin immediately. However, in the case of a declined transaction, players will need to manually click the roll-up button and confirm the transaction before continue mining.

If players are not following the pattern, they will still need to **manually** roll up.

<figure><img src="https://1299308320-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fz14Y82ikqf3KozqsiU9D%2Fuploads%2FtJqLiaEh78ZlY7K48UuL%2Fimage.png?alt=media&#x26;token=6a1bd293-343c-4f77-b934-72f93fff0bf0" alt=""><figcaption></figcaption></figure>

### Extra Reward <a href="#how-to-play" id="how-to-play"></a>

The Combo Giftbox shows the number of combos players have completed, with a progress indicator showing the progress towards next extra reward. Once players reach the "NEXT" combo goal, they will receive extra lumens after the roll-up, and they will advance to the next stage with a higher goal.

\
If players fail to complete a sequence, their completed combo count will be reset. However, the "NEXT" rewarded combo index will remain unchanged, meaning they cannot earn the lumens for the lower goal again. For example, if players fail to complete COMBO x 7, their completed combo count will be reset to 0, but the next rewarded combo will remain COMBO x 10 (rather than combo x 5).

\
**Note**: The completed combo count, including the next goal, resets daily (03:00 AM UTC).
