Pick the right door. Multiply your winnings. Don't get rugged.
Web3 gaming is broken:
- Most games are not provably fair — players can't verify outcomes
- Complex wallet setups create friction for new users
- Gaming rewards are unsustainable — funded by new players (ponzi mechanics)
- No real DeFi integration — gaming and yield are separate worlds
RugMania is a high-stakes survival game where every outcome is verifiable on-chain, wallets are created instantly, and top players earn real DeFi yields from protocol profits.
- Connect — Login with your EVM wallet via Privy
- Bet — Choose your amount and difficulty (3, 4, or 5 doors)
- Play — Pick a door each level. Safe door = advance with higher multiplier. Rug door = game over
- Cash Out — Secure your winnings anytime before the next door
The twist? Every game outcome is determined by cryptographic randomness that anyone can verify.
Every game uses a commit-reveal scheme. The server seed hash is committed before you play, and revealed after — so you can verify the outcome was never manipulated.
No MetaMask popups. No seed phrases. Connect with your EVM wallet and start playing in seconds. Deposit MNT directly in-app.
Track your stats, compete for the highest multiplier, and climb the global rankings.
This is what makes RugMania different.
A portion of house profits is automatically deployed into Mantle's DeFi ecosystem (Mantle Vault, mETH staking). The yields generated are distributed weekly to top 10 leaderboard players.
| Rank | Weekly Yield Share |
|---|---|
| 1st | 25% |
| 2nd | 18% |
| 3rd | 15% |
| 4th-10th | 2-10% |
Why this matters:
- Players earn from protocol success, not just bets
- Creates sustainable rewards without ponzi mechanics
- Drives TVL to Mantle ecosystem
- First GameFi on Mantle with native DeFi integration
| Mode | Doors | Risk | Level 5 Multiplier | Level 10 Multiplier |

5% fee on winnings — sustainable economics that fund operations and Mantle Yield pool.
