Case Opening Guide

Understanding CS2 case mechanics, drop rates, and expected values to make informed decisions.

How to Open Cases

Purchase a case and corresponding key from the Steam Market or in-game store. Each case requires a specific key type to open.

  • Buy case + key
  • Right-click in inventory
  • Select "Open with..."
  • Receive random item

🎲 Drop Rates

Each rarity has fixed drop rates across all cases. Higher rarities are significantly rarer.

Restricted 15.98%
Classified 3.20%
Covert 0.64%
Knife/Gloves 0.26%

Expected Value

Most cases have negative expected value due to key costs. Premium cases with expensive items may have better returns.

Case Investment Tips

🎯 Research Before Buying

Study case contents, current market prices, and historical data before investing in cases.

📈 Long-term Holdings

Discontinued cases often appreciate in value over time as supply decreases.

⚖️ Diversify Portfolio

Don't put all investment into one case type. Spread risk across multiple cases and rarities.

🚫 Avoid FOMO

Don't chase new cases at inflated prices. Wait for market stabilization.
