## How to use swap pools on SWAP
1\. From the main page of MBX NFT, click SWAP. In this guide, let’s try selecting the swap pool for swapping Ticket Puzzles. Click NFT Add.
2\. Next, you must add NFTs to perform the swap. Click the drop down menu for Select NFT Group, and select MBX Marblership Puzzle.
3\. All Marblership Puzzles in your inventory should appear in the NFT List. Try selecting any Ticket Puzzle and click Input NFT.
4\. Notice how the selected NFT is registered for the swap. Click SWAP.
5\. The following pop-up will appear when performing the swap for the first time. Click Approve.
6\. This step is required to grant permission to the MBX NFT service to transfer the NFT for the swap. A small gas fee is required for the approval process. Click Confirm → Approve.
7\. Wait until the NFT approval process is complete and click Approve.
8\. Your NFT is now registered for the swap. To proceed with the swap, click Agree.
9\. A small gas fee is required for the final step of the swap. Click Confirm to proceed. After a few seconds, you will receive a pop-up confirming that the swap was successful. Click Confirm, again.
10\. Congratulations! In this particular swap pool, the reward NFT was an Alphabet Puzzle. Note that it is possible to receive Joker, or Joker(R) Puzzles if you’re lucky! Repeat steps 1-9 in order to swap all Ticket Puzzles in your inventory.
