Verify Hi-Lo

Hi-Lo asks whether the next card is higher or lower. Each card is a single float over a 52-card deck. Faircheck reveals the exact card so you can verify the sequence you bet on.

Verification form

Optional · pre-commit hash check

Paste the hashed server seed the casino published before the bet. Faircheck confirms SHA-256 of your revealed seed matches it — proof the seed was locked in advance.

How Hi-Lo is generated

The algorithm

index = floor(float × 52) · rank = index mod 13 · suit = floor(index / 13)

One float per card is drawn from the HMAC-SHA256 stream.

The float is multiplied by 52 and floored to an index from 0 to 51.

The index maps to a rank (A→K) and a suit (♦♣♥♠) in the standard Stake ordering.
