Zero cost, no paid VRF oracles like Switchboard or Chainlink - Binary search over Solana's SlotHashes sysvar for efficient on-chain hash retrieval - Rejection sampling to guarantee mathematically fair player selection with zero bias - Cranker bot infrastructure and archival RPC fallback mechanisms - Full game logic running on-chain with continuous back-to-back games Frontend (React/TypeScript): - Wallet connection and authentication (Phantom, Solflare, Backpack, etc.) - Real-time game pages with live updates - Player profile pages with stats and history - Full game history with on-chain verification so players can audit every outcome - Multilingual support (i18n) for international audiences - Responsive, polished UI built for a seamless player experience

This guy is the solution. Fast and efficient. Very rare. Definitely an A player. If you want someone that will comprehend and not treat you bad because of a simple inconvenience. This is your person. Went beyond my asking and expectations.
