How it works

1. Sign in

   Sign in with your university email (one account per person), then add your name and a contact (phone, Telegram…). Nobody sees them until you're matched.

2. Verify your ticket

   Sellers upload the ticket PDF or screenshot plus its ticket number. A reviewer checks it, and each ticket number can only be registered once, so the same ticket can't be sold twice here.

3. Bid or ask

   The book is anonymous. A bid at or above the best ask, or an ask at or below the best bid, matches instantly at the resting order's price. Otherwise the order rests in the book.

4. Meet and swap

   On a match, both of you see each other's name, email and contact. You also see each other's track record. Arrange payment and the ticket transfer, then both confirm. The buyer then holds a verified ticket they can resell. Pay at handover, never before.

An independent, student-run exchange, not affiliated with the official Polyball organisers. Payments happen directly between buyer and seller. Check the ticket before you pay.
