 # MLSA Cards DApp
+Play. Learn. Collect. Mint.
 
 A full-stack NFT collectible card game where users solve problems to earn points, purchase digital cards, and mint them as ERC-721 NFTs on the blockchain.
+A full-stack Web3-powered gamified learning platform where users solve domain-based challenges, earn points, unlock collectible cards, and mint them as ERC-721 NFTs with verifiable on-chain ownership.
+Developed as a collaborative MLSA  project, showcasing secure authentication, blockchain integration, and real-world full-stack architecture.
+
+## 🎯 Project Vision
