Every round's crash point is fixed before the countdown, from a secret seed whose SHA-256 hash is shown during the
countdown. The seed is revealed after the crash, and the crash point is
floor(100 × RTP ÷ (1 − u)) ÷ 100, where u is the first 13 hex digits of
HMAC-SHA256(seed, "astronaut:" + round) ÷ 16¹³. Click any multiplier in the history strip to check that round.
