Crate Opening Strategy
1. Redeem Free Codes First

Always check for active codes that give free Release Cases. These are essentially free skins with no cost.

2. Don't Open Crates Early

Save your crates until you understand what skins you actually want. Early openings often give duplicates of items you don't care about.

3. Focus on Series Skin Case

If you want the latest skins, Series Skin Case (400 coins) offers good value with access to newest collections.

4. Understand RNG is Brutal

Drop rates mean you'll get mostly common skins. Don't expect legendary drops - they're rare for a reason. Only open crates if you're okay with getting common skins.

5. Crates Only Give Skins

Important: Crates only provide cosmetic knife skins. They don't affect gameplay performance. All knives have the same stats regardless of skin.

Duplicate & Rarity System
Rarity Tiers
Common

Most common drops, basic designs

Rare

Uncommon skins with better designs

Epic

Rare skins with unique effects

Legendary

Ultra-rare exclusive skins

Duplicate Handling

If you receive a duplicate skin, you'll keep it in your collection. There's no duplicate protection system, so you may receive the same skin multiple times. This is why it's important to only open crates when you're okay with any result.
