TICKET TYPE
This is a mechanics sandbox, not a prediction. Market-price digits are not guaranteed to be uniformly distributed. More possible Box arrangements does not mean a guaranteed win.
UNDER THE HOODA simple game.
Read the full specification A simple game.
Nothing left unexplained.
An external reference.
The proposed result comes from a published stock-market close, delivered by a Chainlink oracle. The goal is an independently checkable input, not a number selected by the operator.
Understand the oracleA pool, not a promise.
Winners share the available pool. Straight receives 70%, Box receives 20%, and 10% is the fee. Your payout depends on the pool and the number of winning tickets — there is no fixed return.
Follow the distributionThe market sets the rhythm.
Four independent books follow the US trading calendar. Regular sessions close at 4 PM Eastern; weekends and NYSE holidays have no draw. Early closes and oracle exceptions need explicit launch rules.
