Frequently Asked Questions
What are the odds of getting a knife from a CS2 case?
The odds of unboxing a knife or glove (Exceedingly Rare items) from a CS2 case are approximately 0.26%, or about 1 in 385 cases. This means on average you would need to open 385 cases ($962.50 at $2.50 per case + key) to get one knife. The actual knife you receive is randomly selected from the case's knife pool.
Which CS2 case is the best to open?
From a pure expected value standpoint, no CS2 case is profitable to open on average -- the house always wins. However, cases with expensive Covert skins and popular knife finishes offer the best potential returns. The Dreams & Nightmares Case, Revolution Case, and Kilowatt Case are popular choices due to their valuable Covert skins. If you want skins, buying directly from the market is always more cost-effective.
How many cases are in CS2?
There are currently 52 weapon cases in CS2, with 3 in the active drop pool. Active cases can drop at the end of matches for free, while retired cases must be purchased from the Steam Market or traded. New cases are typically released alongside major game updates and operations.
What is the most expensive CS2 case?
The most expensive CS2 cases to purchase are typically the oldest retired ones with limited supply, such as the CS:GO Weapon Case (the original case) and the Bravo Case. These can cost $20-50+ each on the Steam Market. However, the most valuable cases to open are those containing the most expensive skins -- cases with Dragon Lore or Howl-tier skins command huge premiums.
