CrateCodex is a reference for CS2 cases, not a place to open them. Every case in Counter-Strike 2 is a sealed container with a fixed, published set of contents and a fixed set of odds, and this site documents both — what is inside, how rarely each part drops, and roughly what the container is worth this month — so you can read the drop pool without ever spending a key.

What this site actually does

It maps each case to its real drop pool. Pull up any case file and you get the same object: a tree that branches from the container into its five rarity tiers, each tier drawn to its published probability, down to the 0.26% gold branch that holds the knife or gloves. The numbers come from the community item API and Valve's own odds disclosure, and every price we mention is a band with the date we checked it.

The full catalogue lives on the all CS2 cases page, where cases are laid out by contents, odds and price band. If you are here for the scarce, appreciating containers instead, the rarest and retired cases page tracks those separately.

Why "opened on paper"

Because opening a case is a bet, and this site is not a casino. The published odds mean that on average you unbox one rare special item every 385 keys, and no case has ever had positive expected value once you price the key. We would rather show you exactly what is in the pool than sell you the pull. That line — document, don't gamble — is explained in full on our About page, and it is why you will never find a case simulator or a scam link anywhere on CrateCodex.

Frequently asked questions

What are the odds of getting a knife or gloves from a CS2 case?

0.26% per opening — roughly one rare special item every 385 keys. Inside a standard case the published odds are 79.92% Mil-Spec, 15.98% Restricted, 3.20% Classified, 0.64% Covert and 0.26% for the gold knife/glove pool. Every case file on CrateCodex draws those exact numbers as a drop-pool tree.

Is CrateCodex a case-opening site?

No, and it never will be. We document what is inside each case — the contents, the real odds and the price bands — so you can see the drop pool without spending a key. We do not run a case simulator. We may cover case-opening and skin-gambling sites, but we never link to scams; the full line is on our About page.

Which CS2 case is the best to open?

The honest answer is that 'best to open' is the wrong question — no case has positive expected value once you price the keys. What people usually mean is which case holds contents worth owning, and we answer that on the all-cases page by contents, odds and price band rather than as a bet.

Why do your case prices show a date instead of a live number?

Because case prices move daily and a static page that prints a live number is out of date within hours. We publish price bands with the date we checked them, link out to where you can verify live, and re-check on a schedule. Odds are fixed by Valve; prices are not.

Why are some old CS2 cases so expensive now?

Supply is frozen. On 17 December 2025 Valve quietly removed the rare weekly drop pool, so legacy cases like Operation Bravo no longer enter circulation from free drops. With no new supply, the scarce ones drift upward — which is exactly what our rarest-and-retired page tracks, with dates.
