Rules of a run

  • Start with £2,000 cash, £5,000 debt, 100 stash slots, day 1 in Peckham.
  • Travelling advances the day and adds 10% debt interest. Day 30 ends the run.
  • Prices shift per borough per day; coastal lines pay more but raise heat.
  • Final score is cash + bank + stash value − remaining debt.

Entry fee

One free run per account. Each further run costs 1 USDC on Base (chain 8453), verified on-chain from the transaction hash you submit.
