How the Simulator Works
This simulator replicates the exact drop rates used in real CS2 case openings. Every virtual case open uses a random number generator with the official probability weights: 79.92% for Mil-Spec (blue), 15.98% for Restricted (purple), 3.20% for Classified (pink), 0.64% for Covert (red), and 0.26% for Knife/Gloves (gold).
The roulette animation is purely visual — the result is determined the instant you click open, and the animation simply lands on that predetermined result. This matches how the real CS2 case opening works.
Why Use a Case Simulator?
Opening real CS2 cases costs money ($2.49 per key) and is statistically unprofitable. The expected value of an average case opening is negative, meaning you lose money on average. This simulator lets you experience the excitement of case openings and understand the odds without any financial risk. It is also useful for content creators who want to simulate openings for videos or streams.
