Provably fair

Japanese Edition Series 1: how we prove every pack is fair.

  1. 1
    The pool is locked before any pack sells

    When a series launches, every card in the pool is shuffled once by a secure random generator. That order decides which card is in which pack, first pack to last.

  2. 2
    We publish a fingerprint of that order

    The fingerprint is a SHA-256 hash of the card order plus a secret code. It's shown below from the moment the series goes live, and it can't be changed without changing the fingerprint.

  3. 3
    When the series ends, anyone can check it

    We publish the secret code and the full card order. Hash them yourself (or tap the button below) and you'll get the same fingerprint, which proves no pull was changed after packs were bought.

This series' fingerprint

a908688e14c03d4aa9b90d92590c70b6b92cd71e8a816dc505dac9fadcb8bfb0

Locked at launch, before the first pack was sold.

Check it yourself

This series is still open, so the secret code and card order stay private until it ends. Publishing them now would reveal which card is in the next pack. Save the fingerprint above and check it once the series is sold out.
