Pick a marble. Physics decides the rest.
Add @MarbleRushArenaBot to a group and send /race for a free race, or /race 90 0.5 — 90 seconds to join, 0.5 TON per marble.
Your entry goes from your wallet straight into the race's own smart contract. It pays the top-3 players 60/25/15 the moment the race ends, and refunds everyone if fewer than 3 players join.
Only TON is used for entries and prizes — in-app there is no other currency. Telegram Stars buy cosmetic skins only.
