Rust case opening is a single-player gambling format where players pay a fixed price to open a virtual case and receive one randomly-drawn Rust skin from the case's weighted contents — the expected value of the skin equals the case price minus the site's built-in house edge.
Key facts
Each case has a fixed contents list with weighted drop probabilities (e.g. a 0.5% chance of the top-tier skin, a 25% chance of a low-tier filler).
The expected value of an open is the sum of (drop probability × skin value) across all possible outcomes — always set below the case price so the house keeps a long-run edge.
The house edge is baked into the case price; there's no separate rake on case openings.
Provably-fair case openings use HMAC-SHA256 on the case + nonce + seeds to deterministically pick the winning slot from the weighted distribution.
