# BlueGem

> BlueGem is a CS2 case-opening site: open cases with gem credits, battle other
> players in case battles, and withdraw winnings as skins or crypto. Every roll
> is provably fair — outcomes derive from HMAC-SHA256 over a pre-committed
> server seed (hash shown before you play), your Cloudflare ray id as the
> client seed, and a public nonce, so any result can be independently verified.
