Provably fair

Every daily seed is committed before the first roll and revealed when the day ends. Each player can reproduce their own prize-roll outcome from public data.

Nov 10, 2026 is still in progress. Its seed will be revealed after midnight Pacific.

How a roll is computed

1. The server creates a random 32-byte seed at the start of each Pacific day and immediately publishes sha256(seed_hex_text).
2. A prize roll uses roll_index = 0. Fun rolls use 1, 2, 3, and so on, and never enter prize drawings.
3. After midnight Pacific, the seed is revealed. Hash it and compare to the published commitment, then run the HMAC below.

import hashlib, hmac

def roll(seed_hex, user_id, day, roll_index, sides):
    msg = (user_id + day + str(roll_index)).encode("utf-8")
    digest = hmac.new(seed_hex.encode("ascii"), msg, hashlib.sha256).digest()
    return int.from_bytes(digest[:8], "big") % sides + 1

# commitment check
assert hashlib.sha256(seed_hex.encode("ascii")).hexdigest() == published_commitment

Seed history

Prize rolls are one per account per day and cannot be replayed. A revealed seed never affects a past outcome; the seed was fixed before any roll.
