RugMania: Provably Fair Gaming on Mantle
RugMania is a high-stakes survival game designed to solve the trust and sustainability issues in Web3 gaming.
The Problem
Trust: Players cannot verify if game outcomes are fair or rigged by the house.
Sustainability: Most games are Ponzis funded only by new players. When hype dies, the game dies.
Our Solution RugMania creates a transparent "Play-to-Win" economy:
Gameplay: Players connect via Privy (frictionless login), bet $MNT, and navigate 3-5 doors. Safe door = Multiplier increases. Wrong door = Game Over. Players can cash out anytime or risk it all for 100x returns.
Provably Fair Tech: We implemented a Commit-Reveal Cryptographic Scheme. Every outcome is determined by a seed committed on-chain before the player acts. This mathematically proves the House cannot manipulate results.
Native Yield Economy: Instead of the House just taking profit, the "House Edge" is architected to route into a Treasury holding Mantle's Native Yield assets (mETH). The passive yield generated from these assets helps replenish the prize pool, creating a more sustainable economy.
Why Mantle?
Micro-Bets: Low gas fees allow us to process every "Door Open" action on-chain.
Native Yield: Our economic model relies on Mantle's ability to generate yield on held assets (mETH) to sustain the treasury.

Progress During Hackathon
During the hackathon, we began by tackling the "trust deficit" in crypto gaming. We identified that players avoid on-chain games because of clunky wallets and unfair algorithms, so we aimed to build a seamless, transparent alternative. We designed a "high-tension" UI with Next.js and integrated Privy to remove the friction of seed phrases. On the backend, we successfully deployed the core game logic to Mantle Sepolia, specifically engineering the "Commit-Reveal" RNG system to guarantee fairness. Crucially, we architected the economic model for the "Yield-Backed Treasury." While the full integration with Mantle Vaults is scheduled for Phase 2, we finalized the design for routing protocol revenue into mETH staking strategies. Overall, we delivered a fully functional, provably fair MVP that is ready for the testnet.
