How It Works
Pay & Join
Connect your wallet and pay the entry fee in ETH or USDC. Your entry goes straight into the prize pool.
Play 4 Rounds
Answer questions across 4 rounds. Each round is randomly majority or minority mode — predict the crowd or defy it.
Win the Pool
Top scorers split the prize pool. Payouts happen on-chain, instantly, with no middleman.
Two Ways to Win
Majority Rounds
Pick what you think most players will choose. Align with the crowd to earn 3,000 points.
Minority Rounds
Pick the least popular answer. When everyone tries to coordinate, thinking differently wins.
Scoring

Prize Pool
The full pool is split among top scorers at the end of the game. Payouts are tiered by final rank — top players take the largest share.
2% Protocol Fee
