Case Arena is a case opening simulator built on real market data. Open cases, unbox skins and knives, and grow an inventory you can actually put a number on.

Every container is modelled on the real market: 330+ containers, 9,400+ items, prices that follow real market values, and weapon cases with the standard drop rates the community knows by heart.

These are the weapon case rates, the same table the game shows. Sticker capsules, souvenir packages, pins, patches, graffiti and music kit boxes do not hold every rarity, so their odds differ. You can read the full contents of any container before you open it.

Questions

Is this real gambling?

No. Every balance, case and skin in the game is virtual. You cannot win real money, there is no cash-out and nothing can be traded outside the app.

Are the drop rates the real ones?

Yes, for weapon cases. Case Arena uses the standard rates the community knows by heart, from 79.92% Mil-Spec down to 0.26% for the gold rare special item. Capsules and other containers do not hold every rarity, so their odds differ.

Do I need an account or internet?

No. The game runs offline and needs no registration. Google Play Games sign-in is optional, for achievements and cloud saves.

Is it made by Valve?

No. Case Arena is an independent fan-made simulator. It is not affiliated with, endorsed by or sponsored by Valve Corporation.
