Your odds over multiple opens

A 0.26% knife chance is hard to picture. This is the same number stated the way it is actually experienced — the chance of at least one, over a run of opens.

100 opens costs $1.1K and returns about $969.98 on average — an expected loss of $80.02.

A coin-flip shot at a knife takes 267 opens — about $2.8Kat this case's price. Even then it is a coin flip, not a guarantee: the odds never carry over between opens. More in our CS2 case odds guide.

CS2 Case Drop Rates

Classified (Pink)3.20%
Covert (Red)0.64%
