What Is This Site
Case Opening Simulator is a free tool that lets you simulate opening CS2 and CSGO weapon cases, capsules, souvenirs, and other containers. It uses publicly known Valve drop rates and is built for fun and curiosity. No real money, no real items, no purchases — just a simulator.
It's Free
Everything here is 100% free. There are no payments, no in-app purchases, no currency of any kind. You open simulated cases and see simulated results — nothing real is created, transferred, or spent.
Valve & Counter-Strike
Counter-Strike 2, CS:GO, and all related assets (weapon skins, stickers, etc.) are trademarks of Valve Corporation. This is a fan-made project. We are not affiliated with, endorsed by, or sponsored by Valve. Game images and data are used for informational and educational purposes.
No Guarantees
The site is provided as-is. We try to keep drop rates accurate and the simulator running smoothly, but we can't guarantee it will always be perfect or available. If Valve updates their rates, there may be a brief delay before we reflect those changes.
