How to Use The Fortune Spin
https://marketplace.roninchain.com/fortune-spin
Each spin is paid with RON/USDC tokens.
Step 1. Connect your wallet to the Ronin market and go to the Fortune Spin page.
Step 2. Choose from the machines available.
Step 3. Choose the amount of spins, then click on the Spin button.
NOTE: If this is the first time you’ll use an ERC-20 token to spin, you’ll have to approve the use of the token first.
Step 4. Sign the transaction with your wallet. Take note that you need to have RON as gas fees and extra RON for VRF allowance.
Once the transaction is confirmed, the result will be revealed. The result is determined by Verifiable Random Function (VRF), ensuring fairness. You’ll see an animated reveal, showcasing your item alongside others from the reward pool.
- If you did multiple spins, the system reveals all at once in an orderly grid.
- If the system runs out of items in a tier at the moment of your roll, you’ll be automatically refunded for that spin.
After each spin, you can now choose to either: (1) claim the NFT to your wallet and keep it; or (2) sell it back instantly to the machine’s pool using a “Sellback Offer.”
Every spins will be logged in the Recent spins section. This is a record of spins opened for that collection that’s available for everyone to view.
Claiming the NFTs
After spinning, the items you get will be stored in your Event Inventory. If you prefer to keep the item or trade it with other users/wallets, you have the option to claim the items as NFTs.
To claim an item, simply go to the item’s page and click Claim pending item. Confirm the transaction and the NFT will be sent to your wallet after a few minutes.
If you would like to claim multiple items at once, you can select multiple items in the Event Inventory page by clicking the + button on each item, then clicking Claim X items on the bottom of the page.
For multiple item claims, you’ll need to sign a transaction for each machine you’re claiming from.
Sellback Offer
Sellback offer gives you the chance to turn items you don’t want to keep into additional chances to roll. The offer price starts at ~90% of the reward item’s tier value and decays every 15 minutes over a 1-hour window down to ~50%. You have 24 hours to accept before the offer expires.
If you accept the sellback offer, the item goes back into the supply pool. Take note that Creator Fees may apply during this transaction unless disabled by the creator.
Sellback from Results Page
After spinning, you have the option to instantly sell them back in the interface. If you want to proceed with selling the items back, click on Sell at market button.
The total sale price will be shown on the button, but depending on the creator fee set on the collection, the amount you’ll receive might be slightly lower.
If you did multiple spins, you’ll also have the option to select specific items to keep while selling the rest using the Choose items to sell button.
Sellback from Event Inventory
To sell back an item from your event inventory, simply go to the item’s page and click Sell for market. Confirm the transaction and the item will be sold back for the indicated price.
If you would like to sell multiple items at once, you can select multiple items in the Event Inventory page by clicking the + button on each item, then clicking Sell X items on the bottom of the page.
For selling back multiple items, you’ll need to sign a transaction for each machine you’re selling back to.
Item Pool
Each spin in Jin’s Fortune Spin draws from a curated Item Pool—a collection of NFTs grouped by rarity tiers.
Here’s what you need to know about the reward pools:
- One spin = one random NFT, based on the tier odds.
- NFTs can come from single or multiple collections and are grouped by tier.
- The pool is dynamic and can be updated by the supplier to add or remove items.
- Successful sellbacks directly replenish the Item Pool.
When a specific tier runs out of NFTs, the machine is considered out of stock and cannot be purchased.
A machine is automatically restocked when either of the following happens:
- A supplier adds new NFTs to the depleted tier; or
- Another user sells back an NFT of that tier via the buyback system.
Once resupplied, the machine becomes available for spin again.
Recent Spins/Activities Log
After every spin, each result will be logged in the Recent spins section in each collection. This log can be viewed by anyone.
On the View all page, you can use different filters if you just want to see specific logs:
- Default - Shows all spins for that collection.
- Top tier - Shows all openings that resulted in a top-tier item.
- Opened by me - Shows only the spins that you have opened yourself.
You also have the option to use the search bar if you want to filter out openings made by a specific user by entering their Ronin address/RNS.
