HOW IT WORKS
Complete guide ยท Onchain Slots Neon
๐ฐ OVERVIEW
Onchain Slots Neon is a fully onchain NFT slot machine on Ethereum. Connect your wallet, pay the spin price, and the smart contract determines your outcome instantly on-chain. No IPFS. No centralized randomness. All NFT artwork is generated in pure SVG stored entirely on-chain.
๐ฒ PROBABILITY TABLE
Win outcomes only activate if the prize pool has balance. If not, the contract auto re-rolls to Mint or Refund.
๐ฐ PRICE TIERS
Price updates automatically based on total supply. Total supply: 15,000 NFTs.
๐ฐ PHASE SYSTEM
Pool win percentages change automatically based on total supply minted. This protects the pool as it grows.
๐ฐ EARLY PHASE โ Tokens 1 to 7,500
๐ฎ LATE PHASE โ Tokens 7,501 to 15,000
The current phase is shown in the prize pool indicator. Win amounts in ETH are always displayed live.
๐ด MINTING AN NFT
When your spin lands on MINT (72.5%), the contract mints a unique NFT directly to your wallet.
Your NFT stores the spin price paid at mint time. This is used to calculate the burn spin value.
๐ฅ NFT VALUE & BURN SPIN
Every NFT has a burn spin value equal to 90% of the price paid when it was minted.
Example: Minted at Tier 1 (0.00005 ETH) โ Burn value = 0.000045 ETH
When you burn an NFT, the contract withdraws 90% of its stored mint price from the prize pool and runs a full spin with that value. REFUND = get 90% back. LOSS = 90% goes back to pool. MINT = new NFT using 90% as the price.
๐ POOL WIN SYSTEM
Win outcomes pay a percentage of the current prize pool โ not a fixed amount. The bigger the pool, the bigger the win. Percentages change between Early and Late phase automatically.
Win amounts in ETH are shown live in the Prize Pool indicator. The pool grows with every mint (90% of each spin) and every loss (99%).
โญ LEGENDARY NFT BONUS
Holding a Legendary NFT gives you an extra 1% of the pool on top of any win. Applies to all tiers in both phases.
๐ REFERRAL SYSTEM
Free spins can only result in a mint or nothing. They never access the prize pool. No limit on how many referrals you can earn.
๐ LOSS OUTCOME
Losses fuel the pool, making wins larger for everyone.
