NumSum is a decentralized blockchain-based guessing game where players bet small amounts of ETH and try to guess the sum of two random numbers. If the guess is correct, the player instantly wins 2× their bet through an automated smart-contract payout.
Our mission is to make blockchain gaming simple, transparent, and beginner-friendly. NumSum aims to teach developers the basics of smart contracts, randomness, and payouts while giving users a fun, fair, and trustless gaming experience on Ethereum testnets.
Traditional online games lack transparency, fairness, and trust. Players have no way to verify randomness, payouts, or if the system is manipulated. Beginners also struggle to understand how blockchain-based games work because existing platforms are too complex.
NumSum solves this by providing a simple, transparent, and verifiable blockchain game built on Solidity. Every bet, random generation, and payout is handled by a smart contract. Players see instant, trustless results, and developers can use the project as a beginner-friendly template for building transparent Web3 games.
