This project implements a Plinko game smart contract on the Solana blockchain using Anchor framework. Players drop balls into a Plinko board, and rewards are determined based on the landing bucket. The game integrates randomness via the Orao VRF Oracle to ensure fairness and transparency.
-
🪙 On-chain Solana smart contract for Plinko gameplay.
-
🔑 Secure account management using PDAs (Program Derived Addresses).
-
🎰 Verifiable randomness using Orao VRF Oracle.
-
📈 Track player stats (total won, buckets hit, etc).
-
🏦 House account logic for managing payouts and balance.
-
⚡ Efficient SOL transfers using system instructions with PDA signing.
-
✅ Tested and structured using Anchor framework.
- Start a game
The player calls play_game, placing a bet and specifying parameters (e.g., number of balls).
- Request randomness
The contract makes a request to Orao VRF.
- Fulfill randomness
Orao VRF provides random numbers; the contract processes them via fulfill_random_words.
- Determine payouts
Based on bucket indexes, payouts are computed and distributed between player and house.
- Update stats
Game, house, and user statistics are updated on-chain.
