Mystery Chests Explained: Odds, Pools and What You Are Buying

A chest is not a lottery ticket. It is a slice of a pool that already exists — accounts we hold, with skins already on them. That difference is the whole reason the odds on the card can be printed at all.

What the pool actually is

Every chest tier points at a set of accounts sitting in stock. «25–50 random skins» is not a promise the system will generate something: it is a filter over real inventory. When you buy, one of those accounts leaves the pool and comes to you, which is why the remaining count on the card drops by one.

This is also why a chest can sell out. A pool is finite, and when it empties the chest disappears from the catalogue until it is refilled.

Reading the OG chance

The printed OG chance is the share of accounts in that pool carrying at least one rare Chapter 1 cosmetic. Five percent means five accounts in every hundred, counted before you buy — not a feeling, not a marketing number.

What it does not mean:

• It is not per-skin. One rare item on the account satisfies it.
• It is not cumulative. Buying twenty chests at 5% does not guarantee one.
• It does not change as the pool drains. The share is maintained on refill.

If a site states odds without stating the pool, the odds are unfalsifiable. Ask what the number is a share of.

Why the remaining count matters more than price

Two chests at the same price with the same odds are not equal if one has forty accounts left and the other has four. A thin pool means the next refill may change the mix, and it means the tier is close to selling out.

The card shows what is left for exactly this reason. A cheap chest over a nearly empty pool is worse value than a slightly dearer one over a deep pool.

Bundles and the free-chest ladder

Buying several chests at once does two things: the per-chest price drops from three, and from six the ladder adds free chests on top. The discount applies to the paid ones; the free ones are drawn from the same pool with the same odds — they are not a separate, worse bucket.

What you get and what happens if it fails

Delivery is automated. Credentials appear in the dashboard the second payment clears — there is no seller in the loop and nothing to wait for.

If an account does not work, it is replaced from the pool. That is the practical difference from buying an exact account from a seller: there is no dispute to open, because the marketplace is the seller and the pool is right there.

Chests by game: all mystery chests. If you would rather name the skin than take the odds, named orders work the other way round — and if you want the exact locker instead, the item shelves list accounts that already hold it, like Black Knight or Ikonik.
