Provably fair

Odds & fairness

Every box shows its drop rates up front. Then cryptography proves each outcome was honoured — and you can check it yourself.

The odds

Every box shows its hand

No box hides its rarity mix. Widths below show a typical spread — each box page prints its own exact numbers.

The proof

How provably fair works

Three cryptographic steps that lock the odds in place — none of which we can fake.

  1. Step 01 · Commit

    Before the roll

    We generate a secret server seed and publish its SHA-256 hash up front. You add your own client seed — so neither side can rig the result.

  2. Step 02 · Reveal

    The roll

    The outcome is a deterministic hash of the seeds and roll number:

    HMAC-SHA256(server_seed, client_seed:nonce)
  3. Step 03 · Verify

    After the roll

    The server seed is revealed, so anyone can confirm:

    • The published hash matches the revealed seed
    • The roll calculation reproduces exactly
    • The result could not have been manipulated
Our commitment

We cannot predict or change an outcome after a seed is committed. The cryptographic proof guarantees every roll is fair and random — verifiable by you, every single time.
