The math is public
Valve publishes tier odds: 79.92% blue, 15.98% purple, 3.2% pink, 0.64% red and 0.26% gold. This simulator uses exactly those numbers with live prices — so your simulated luck matches real unboxing odds.

Open any of 42 CS2 cases with the official drop odds (79.92% blue → 0.26% gold), the real wear distribution and a 10% StatTrak™ roll — every drop valued at live multi-market prices. Watch your session profit and loss add up before you ever pay for a real key.
Valve publishes tier odds: 79.92% blue, 15.98% purple, 3.2% pink, 0.64% red and 0.26% gold. This simulator uses exactly those numbers with live prices — so your simulated luck matches real unboxing odds.
For nearly every case the expected return is far below the case + key cost. Open a few dozen simulated cases and watch the net result line — that red number is what real unboxing does to a wallet on average.
If you want a specific skin, buying it outright is almost always cheaper than chasing it in cases. Use the ROI tier list to see the least-bad cases, and marketplace comparisons to buy skins at the lowest fee.
Yes. The simulator uses the official tier odds Valve disclosed (79.92% / 15.98% / 3.2% / 0.64% / 0.26%), the community-measured wear distribution and the 10% StatTrak chance. Item values are live lowest multi-market quotes.
No — it is a free educational simulator. Nothing is bought, sold or dropped. It shows what case odds feel like before you spend real money on keys.
Because that is what the odds are: roughly 4 of every 5 drops are Mil-Spec (blue). A gold — knife or gloves — appears about once per 385 opens on average, and averages hide long dry streaks.
On average, no — expected value is well below cost for essentially every case. Individual lucky drops happen, which is exactly what keeps people opening. If you enjoy it, budget it as entertainment, not investment.
