3. Tickets & Pricing

System tickets

A ticket can select k distinct numbers between 1 and 60, where 6 ≤ k ≤ 15. The ticket represents all 6-number combinations from those picks: [ \text{combos} = \binom{k}{6} ]

Price formula

• Let ticketPriceUSDT / ticketPricePLAY be the price per 6-number combo.

• A ticket with k selections costs: [ \text{totalCost} = \text{pricePerCombo} \times \binom{k}{6} ]

Example

• If pricePerComboUSDT = 1 USDT and k=10, cost = ( \binom{10}{6} = 210 ) USDT.

Tickets are minted as soulbound ERC‑721. Token ID encodes (roundId << 32) | ticketIndex.
