Hi-Lo
How a Hi-Lo result is derived, step by step. Every step is public and can be reproduced from the seeds.
Derivation
- 01
Cards come from an infinite deck: card k = floor(float(k) × 52), rank = card mod 13, suit = floor(card / 13).
- 02
From rank r (0 = ace … 12 = king): P(higher or same) = (13 − r) / 13, P(lower or same) = (r + 1) / 13.
- 03
One nonce covers the whole round; the card sequence is fixed when it starts.
float(k) and the rest of the notation are defined in the byte stream.

Open the verifierRules that fix the payout
A card is shown. Call the next card higher-or-same or lower-or-same, or skip the card at no cost (up to 52 skips).
Each correct call multiplies your payout by 0.99 / p, where p is the exact probability of that call. A wrong call ends the round.
Cash out after any correct call. Aces are low, kings are high.
