How to Play
Buy a ticket for $3, then scratch the card to reveal diamonds. The number of diamonds determines your prize tier — more diamonds means a bigger win. Each card has a 20-cell grid; tier 0 (no diamonds) is a loss, while tier 15 (all 20 diamonds) is the $10,000 mega jackpot.

Ticket System
Each ticket costs $3. The cost is split as follows:
- $1.50 → Ticket Claim Vault (your locked ticket that matures back to $3 through yield)
- $1.25 → Prize Pool (funds all prize payouts)
- $0.25 → Protocol fees
Provably Fair
Scratch uses onchain VRF for randomness. Each ticket's outcome is determined by keccak256(randomness || index) % 10,000,000 mapped to the tier probability thresholds above. The randomness source and outcome computation are fully on-chain and verifiable — neither the house nor the player can manipulate results.
