How the Case Opening Simulator Works

Every opening is simulated with the same tier odds CS2 applies to real weapon cases, so the distribution of blues, purples, pinks, reds, and golds you see here matches what you'd get spending real keys. StatTrak versions roll at roughly 10% on non-special drops, and each case's contents mirror the real drop pool — check any case page for the full skin list and per-skin odds.

Pull values use live Buff163 market prices, and the sidebar tracks how much you've spent on cases and keys against the market value of everything you pulled. Over a long session the ROI stat shows why opening cases loses money on average — if you want the exact math, see the case odds calculator and our deep dive into the real case-opening math.

These tier odds are identical for every standard CS2 weapon case — what changes between cases is which skins sit in each tier and what they're worth.

Frequently Asked Questions

Is the CS2 case simulator free?
Yes. Every opening is simulated in your browser at no cost — no account, no deposit, and no limit on how many cases you open. Your session stats (spent, value, profit, ROI) are tracked so you can see how openings play out over time.
Does the simulator use real CS2 case odds?
Yes. Drops follow the same tier odds CS2 uses for every weapon case: 79.92% Mil-Spec, 15.98% Restricted, 3.20% Classified, 0.64% Covert, and 0.26% for a knife or gloves. StatTrak versions appear on roughly 10% of non-special drops.
What are the odds of pulling a knife in CS2?
A Rare Special Item (knife or gloves) drops at 0.26% — about 1 in 385 openings. The simulator uses the same rate, so a long dry streak here is exactly what real openings look like.
Are the skin values in the simulator real prices?
Pull values come from live Buff163 market pricing, refreshed with our skin price data. The profit and ROI stats compare what you spent on cases and keys against the current market value of everything you pulled.
Do I keep the skins I open in the simulator?
No — openings are simulated, so nothing is added to your Steam inventory and no real money is spent. If you want a specific skin, buying it directly on a marketplace is almost always cheaper than opening cases for it.
