Free CS2 & CSGO Case Opener

Weapon cases, sticker capsules, souvenir packages, autograph capsules, graffiti sprays, music kits, patch packs, collectible pins. If CS2 lets you unbox it, it's here. The whole simulator runs on Valve-confirmed drop rates so you get the same odds as Steam. Pick something above and start opening, or toggle Multi to queue up a few cases and cycle through them back-to-back.

What Can You Open?

We loaded up the full catalog of CS2 and CSGO containers with accurate drop tables and live market prices. Here's what's in the box.

Weapon Cases

The original CSGO Weapon Case all the way through Kilowatt and Gallery. Knives and gloves hide in the rare gold pool at ~0.26% odds, and 10% of weapon skin drops come out StatTrak.

Sticker Capsules

Community, tournament, and themed collections. Holos, Foils, Golds, Glitters, Lenticulars. We have capsules from all the Majors and community series.

Souvenir Packages

Dropped during Major matches with gold tournament stickers already on them. The loot tables pull from map collections, so you'll see Consumer and Industrial grade skins that don't exist in weapon cases.

Autograph Capsules

Pro player signature stickers. Regular, Holo, Foil, Gold. The right player on a Gold sticker can be worth hundreds.

Graffiti, Patches & Pins

Graffiti you spray on walls mid-round, patches that go on your agent, and pins that show up on your profile. Rarity-tiered like everything else.

Music Kits

Replace your menu music, MVP anthem, and round start sounds. StatTrak versions track your MVP count. All the community and artist collab kits are in here.

How It Works

The simulator rolls the same rarity tiers and per-item probabilities as a real CS2 unboxing. Knife and glove odds are 0.26% (1 in 385). StatTrak is a flat 10% chance on weapon skins. Wear floats get randomly assigned within each skin's min/max range. Your session keeps a running tab of total spend, profit/loss, and ROI.

Opening Modes

  • Classic — one at a time with the full reel animation. Toggle auto-open for continuous openings at adjustable speed (0.5x–10x).
  • Bulk — simulate up to millions of openings at once and get a heatmap breakdown of everything you hit.
  • Multi / Cycle — select a bunch of different containers and rotate through them like an unboxing stream.

Plan Your Unboxing Budget

Use our CS2 case calculator to pick cases, set quantities, and see the total cost with live Steam Market prices and key prices in 160+ currencies. Then send your plan straight to the simulator to open everything and see what you would have gotten.

Test Before You Spend

Most people lose money opening cases. Run a few hundred openings here first and you'll see how many blues you sit through before a pink or a gold knife shows up. Useful for figuring out if that 50-case session is worth the cost before you actually buy the keys.
