BlockSlide is a fully interactive puzzle NFT game built on Flow blockchain

Contract code at https://github.com/naman14/BlockSlide/blob/main/cadence/FlowPuzzleNFT.cdc

• Contract determines shuffling order for each tokenId

• User solves the puzzle, user’s solution moves are packed in a format that is highly gas efficient

• Mint function is called by user with packed moves

• Contract verifies the moves with the original shuffle order determined by the contract itself.

• Contract saves the packed moves of user for interactive NFT metadata and replay NFT

• Replay of moves user did to solve puzzle

• Score assigned based on moves count compared to least possible moves

• Different borders assigned based on score

• Unique music in each NFT

• Combination of puzzle and solution results in a unique music associated with NFT

• Every user will get unique music based on moves done to solve puzzle

• Hundreds of thousands of unique music possible

Since the moves of a user are processed on chain to verify if the puzzle was actually solved, the moves need to be packed in a highly gas efficient way This logic is present at https://github.com/naman14/BlockSlide/blob/main/src/onchainmoves.js
