Case Opening Simulator is a multiplayer case-opening game where you open cases, collect skins, build your inventory, and try to grow your balance.

Open cases to pull skins across different rarities, sell items for in-game money, upgrade skins for a chance at higher-value rewards, or use the trade-up system to turn multiple items into something better.

You can also earn money through parkour challenges and use it to keep opening, upgrading, and trading up.
