Connect a wallet to take a side.
Five minutes, aligned to the clock. One window is running and takes tickets at a live price; the next one is loading and takes them at even money. When the running one closes it settles, the next becomes live, and a fresh one opens the same second.
Buying into a window that has already moved would otherwise be free money — three seconds before the close, with the answer on screen, you would get the same odds as someone who bought blind. So every ticket is priced when it is bought:
Buy at 90¢ and you are paying for something 90% likely, so it pays little. Buy the 10¢ side and it pays a lot, because it usually loses.
Any open position can be sold back while its window runs, at fair value less a haircut that steepens toward the close — 2% at the open, 31% at the freeze. Holding always beats bailing on a near-settled position, which is what keeps this solvent without a house.
Nothing moves at all in the final 30 seconds.
Winners keep 100% of their stake and split what the losing side left behind, weighted by the price they paid.
The rake comes out of the surplus only — never winner principal, and nothing at all on a void. Settlement divides what the round actually still holds, so it can never pay out more than it has.
Every ticket is worth at least $2 in BINS, priced when the window opens and pinned. A window needs 5 unique wallets or it voids and refunds in full.
Every mark is the median of Binance, Coinbase, Kraken and OKX. If fewer than two answer, or they disagree beyond the limit, no mark is published and the window voids rather than settling on a suspect number.
BINS you deposit is held by the operator, and the round ledger is a database, not an on-chain program. You are trusting this operator with custody. Withdraw what you are not actively trading.
