Case Or Key

The Case Or Key case has 20 possible results, all named after CS2 cases or keys. It has no knives or gloves in its pool. The highest-value results are cases, but the odds lean heavily toward two lower-value cases. The item list on this page shows the chance of each result alongside its current value.

Who the odds suit

Case Or Key suits a player who wants a small chance at a higher-value case or key and is comfortable with the more likely result being worth less than the opening costs. Fracture Case has a 50% chance, while Prisma Case has a 29% chance; neither is worth more than the case costs. Horizon Case, at 2.5%, also falls below that mark. The chance of winning more than the case costs is 18.5%. That figure describes the odds of a single opening, not what a run of openings will return.

Results at the top of the pool

The most valuable outcomes have much smaller individual chances than the common cases. The leading results include:

• Operation Bravo Case, the most valuable item, with a 0.02% chance.
• Operation Hydra Case, with a 0.03% chance.
• Operation Breakout Case Key, with a 0.05% chance.
• CS20 Case Key, with a 0.1% chance.
• Chroma 3 Case Key, with a 0.2% chance.

Each of these is worth more than the case costs, but none is a likely result on its own. The pool also includes less valuable outcomes with higher chances, so a rare result should not be treated as the expected return.

Before and after a spin

Before opening Case Or Key from your balance, you can try its Demo Spin without spending anything or winning anything; for a paid spin, you can open one to five cases at once and select a faster spin speed. Each opening uses a hashed server seed shown before the spin, your client seed and a nonce, and you can check the result in your game history. A win is credited to your balance at market value right away; from there, you can buy skins on the CSDROP marketplace to withdraw to Steam, withdraw in crypto or keep playing.
