Odds you can read. Draws you can check.

Real-money chance mechanics only work if the odds are honest and the draw is auditable. Pokécha builds both in at the engine level, not as marketing copy.

Published odds

Every probability shown on a pack comes from the same solved configuration the random draw runs against — there is no separate “marketing” odds number that could drift from reality. The engine refuses to publish a pack unless every tier's probability is strictly positive and the consolation floor is above zero, which is what guarantees every opening returns something of value.

Live availability

A graded slab is one physical item, so a tier backed by one can run out. Every odds table shows how many are left, read from the same stock count the draw itself uses. When none are left the published chance does not change — that is still what the random roll does — but landing on that tier pays the tier's published fallback instead, so the opening still returns value and the guaranteed floor is unaffected.

Proof-backed fair draws

Each opening is committed to before it is revealed:

1. The server generates a secret serverSeed and stores itsserverSeedHash before drawing.
2. It draws using that seed plus a public clientSeed and nonce.
3. After the result, the serverSeed is revealed. Anyone can hash it to confirm it matches the pre-committed hash, then recompute the roll and land on the same tier — exactly what the Verify this draw button does on each reveal.

Because the hash is fixed before the draw, the house cannot change the outcome after seeing it, and you can prove it.
