## Frequently asked questions

### Are case opening sites rigged?

Reputable sites use provably fair systems, which let you verify that each outcome was fixed before you opened the case and not changed afterwards. That does not remove the house edge: most cases return less than you pay on average, so check each case's odds and expected value before opening.

### Can I withdraw skins from case opening sites?

Yes. Most case sites let you withdraw items to your Steam inventory, usually through a P2P marketplace where another user sends the skin. Steam trade holds and minimum withdrawal values can apply.

### What is a case battle?

A case battle is a mode where two or more players open the same set of cases and the player (or team) with the highest total item value wins all the items. See our guide to case battles for modes and strategy.
