2048: A Guide to Building High Performance Games on Monad

Monad2048 is an on-chain implementation of the popular game 2048, designed to demonstrate best practices for creating high-throughput, responsive on-chain applications. The game logic is split between off-chain application code and on-chain smart contracts, presenting a trade-off between user experience (UX) and security.

Key Ideas

Balanced Approach to Randomness: The article highlights the challenge of generating new tiles in a way that balances randomness and responsiveness. The implemented solution uses a deterministic random number generator with occasional feedback from the smart contract to prevent cheating while maintaining a snappy UX.
Smart Contract Design: The smart contract for Monad2048 is designed to validate each move and ensure the game rules are immutable and publicly verifiable. It stores the latest board state and processes new moves incrementally, allowing users to resume their games upon refreshing their browsers.
