A room-based casino platform on Solana where friends can create rooms, bet together, and play fun on-chain games like Mines!
👥 Create rooms, invite friends, place bets, and let the smart contract decide the winners based on fairness and cryptographic randomness.
- Frontend: Next.js ⚛️
- Server: Node.js 🟢
- Blockchain: Solana
- Popular platforms like Stake only let users play against the house.
- There’s no way to play casino games directly with friends.
- The entire game logic and randomness are controlled by a centralized backend.
FriendzCasinoOnSolana offers a new model for online gambling:
- 🎯 Room-based multiplayer games where friends can bet and play together.
- 🔐 Smart contracts enforce fairness — no centralized control over outcomes or funds.
- 🎲 Commit-reveal randomness ensures that no one can tamper with the result.
- 💬 Collaborative gameplay builds trust and fun through shared experiences.
- 🌍 On-chain integrity guarantees transparency, immutability, and fairness in every game.
Unlike most casino platforms or even Web3 games, FriendzCasinoOnSolana is built entirely on-chain.
- 🏗️ Room creation, joining, and player management all happen via Solana smart contracts.
- 🧑🤝🧑 No off-chain matchmaking or session tracking — the blockchain itself is the game server.
- 🚫 No WebSockets or centralized state sync — game state and interactions are updated and retrieved entirely through on-chain transactions and events.
- Transparency: Every player action and game event is recorded on-chain for public verification.
- Trustless Play: You don't have to trust any backend server — the smart contract is the backend.
- No Middlemen: Even multiplayer coordination (room IDs, player counts, turns) is handled trustlessly.
- Auditable Gameplay: Anyone can replay or verify games by scanning the chain.
