How CS2 Case Opening Works

CS2 case opening sites work differently from Steam cases. Instead of buying a key for each case, you use site balance or deposited skins. When you open a case, the site's algorithm picks a random skin from the case's loot table — the odds for each skin are published on the best sites.
