This project is a decentralized, on-chain implementation of the classic Tic-Tac-Toe game, built using the Clarity smart contract language and deployed on the Stacks Testnet. The smart contract enables two players to wager STX tokens and compete in a fully trustless and transparent environment, where every move, bet, and outcome is verifiable on the blockchain.
The contract handles game creation, joining, move validation, winner determination, and bet payouts — all without any centralized server.
The vision behind this project is to demonstrate the capabilities of decentralized gaming on the Stacks blockchain. By building a game with real value transactions and deterministic rules, we aim to:
- Showcase the potential of Clarity smart contracts for interactive applications.
- Encourage developers and gamers to explore on-chain game mechanics.
- Establish a foundation for more advanced and competitive blockchain-based gaming experiences.
- ✅ Create New Game: A player can initiate a game with an STX bet and an opening move.
- 🔄 Join Existing Game: A second player can join by matching the bet and making a move.
- 🎮 Play Turns: Alternating moves are made in turn by each player, enforced by the smart contract.
- 🧠 Move Validation: Ensures valid index, move type (X or O), and non-overlapping cell updates.
- 🏆 Winner Detection: Automatically detects winning combinations and declares the winner.
- 💰 Bet Handling: Secure STX transfer and winner reward handled directly by the contract.
- 🔐 On-chain Logic: Entire game logic (board state, turn tracking, and result handling) is stored and computed on-chain.
- 🧩 Game UI Integration: Build a front-end interface (e.g., React + Stacks.js) for users to play the game easily.
- 💬 Move History & Chat: Add metadata or logging features to track past moves and enable player interactions.
- 🪙 NFT Rewards: Mint NFTs as proof of victory or participation using the Clarity NFT standards (SIP-009).
- 👾 Game Modes: Introduce more game types (e.g., 4x4 boards, tournament brackets).
- 🧪 Unit Testing & Auditing: Add test coverage and run audits for security and consistency.
- 🌍 Multiplayer Lobby System: Allow multiple games and players to interact via a smart contract lobby mechanism.
