Every round starts a 5-minute countdown. Each buy of 0.05 SOL or more adds 1 minute to the timer (max 2 hours). When the timer reaches zero, the last person who bought wins the entire jackpot. A new round starts automatically.

Every trade on pump.fun generates a 0.30% creator fee. All of it goes into the jackpot. No dev cut. No team allocation. The winner gets everything that accumulated during the round.

When the timer hits zero, the accumulated creator fees are claimed and sent directly to the winner's wallet. No manual claiming needed. Every payout is verifiable on-chain via Solscan.

The best time to buy is when the pot is fat and the clock is low. But everyone else knows that. Each buy pushes the timer back up, growing the jackpot but delaying the end. That tension — wanting to be last while knowing someone else might buy after you — is the game.
