How do CS2 cases work?

You buy a weapon case and its matching key, then open it for one random skin. The skin comes with its own float, pattern and a chance of StatTrak. Every case shares the same five rarity tiers, from blue mil-spec up to the covert reds and the rare gold knives or gloves.

Do you need a key to open a CS2 case?

Yes. Every weapon case needs its own key. Steam sells keys in-game for about $2.50, which sets the ceiling on what a key is worth; third-party markets sometimes list them for a bit less. Case prices vary widely: common ones cost a few cents, but older discontinued cases can be worth far more than the key. This simulator adds the current case and key price together as your cost to open.

What are the odds of unboxing a knife in CS2?

The gold tier (knives, or gloves in glove cases) drops at about 0.26%, roughly 1 in 400 openings. The other official rates are 0.64% covert red, 3.2% classified pink, 15.98% restricted purple and 79.92% mil-spec blue. Every item also has about a 1 in 10 chance to be StatTrak. Use 'open until gold' here to see how many cases a knife really takes.

Are CS2 cases worth opening?

Usually not. Open a batch here first: the simulator totals your case and key cost against the market value of every skin you pull. Most opens return a cheap blue or purple, so nearly every run ends below what you spent. Buying the skin you want outright is almost always cheaper than chasing it in cases.

Are the drop rates in this simulator real?

The tier odds (blue, purple, pink, red and gold) are Valve's official published rates. Per-item chances inside a tier, wear rolls and Doppler phase splits are estimated from the item pool, since Valve doesn't publish those. Skin values use live prices from the market you select.

What do the cost, return and profit numbers mean?

Cost to open is the case plus its key. Total return is the market value of everything you unboxed. Profit or loss is return minus cost, and the percentage by return shows how much of your spend came back, where 100% is break-even. Est. profit on a case is its average return per open minus the cost, weighted by the odds.
