Labubu secret odds by box count

What does each purchase size actually buy? Almost every number passed around this hobby is a per-box rate — and almost every decision is made in purchase sizes: one box, a set, a case. These pages convert one into the other, for every reported series format, in the open where you can check the arithmetic. Last updated 2026-08-31.

Model: independent single-box draws at the printed odds. Sealed-case allocation can differ — these numbers model loose boxes. The authoritative number is always the one printed on that series' own box; the rates here are collector-reported for orientation (sources in the dataset).

Quick answers

Does a sealed case guarantee a secret?
No. A sealed case typically guarantees one of each regular figure. At 1:72 printed odds, twelve boxes carry a 15.5% chance of at least one secret and an expected count of 0.17 — about one secret per six cases.

Does 1:72 mean the 72nd box is the secret?
No. 1:72 is the rate per box, not a countdown. Buying all seventy-two gives a 63.5% chance of at least one secret — leaving more than a one-in-three chance of ending with none.

Open data

The whole table — every format × every purchase size, plus the thresholds — is published as a CC-BY dataset at /data/pull-math.json. It is computed from rarity-odds.json so there is never a second source for the same numbers.
