Bought under odds version cmv6tss7n000f1dka53d09fxt; drawn under odds version cmv6tss7n000f1dka53d09fxt, the odds published when it was opened. The checks below are against the table it was drawn under, which was published at 2026-10-13 15:18 UTC, before the pack was opened at 2026-10-13 15:19 UTC.
Our secret number was locked first
This pack's sealed code was published before the pack was opened. The secret number we revealed afterwards produces the same code, so we did not change it.
The pack was picked from 5 sealed packs on the shelf. The numbers below include the packs that were not picked.
Numbers for this check
- Sealed code, published first
- d690f3ca15b39902eedd800f344a8b1b0cf084091c41c886d0ef741f694c7c70

- 0be1d53e4560f8fd9abc0e47df3716b74b3b85b9ca4d8126229fd5fdb59f12e7
- SHA-256 of our secret number
- d690f3ca15b39902eedd800f344a8b1b0cf084091c41c886d0ef741f694c7c70
Every pack on the shelf showed its sealed code before the pick. The secret numbers of the packs that were not picked are revealed here, so anyone can check that the packs were all different: the SHA-256 of each one matches the code shown on the shelf. Those packs never had a result. A result needs the player's number, and only the picked pack received one.
- Picked pack (this draw)

The published odds set the value band
Our secret number and the player's number combine into a roll between 0 and 1. The odds published for this pack divide that range into value bands, and the roll falls in exactly one.
The roll 0.355388 falls in the value band Common, which covers 0.000000 to 0.661268.
Numbers for this check
- Formula
- HMAC-SHA256(serverSeed, `${clientSeed}:${nonce}`) → bytes 0–7 = roll1, bytes 8–15 = roll2
- The player's number (client seed)

The card came from the locked card list
Within its value band, every card's chance is proportional to 1 ÷ (value − $9.31), so a dearer card is always rarer than a cheaper one beside it; the band totals are the published ones, and they add up to 100%. $9.31 is set each time the table is solved, so the pack returns its published target. A featured card is only a label: its chance comes from the same formula. The second roll used each card's weight from that rule. Recomputing the pick gives the card the draw recorded. That card is on the card list locked when these odds were published.
