A Complete Guide to CS2 Cases: Every Case, Odds, and Which to Open

CS2 skins are by far the largest video game-based economy in the world. The CS2 skin market is incredibly complex, with years of history, a market cap that has peaked above $10 billion, and over 2 billion individual items across tens of millions of inventories. At the heart of it are CS2 cases, the core mechanic that makes the entire CS2 skin market possible. Most skins start in a CS2 case, and CS2 cases have evolved into a product that makes Valve over $1 billion annually and has even made a few players quite wealthy themselves. In this guide, we will cover everything you need to know about CS2 cases, including every case released, drop odds, key prices, rare vs. active drops and the rare drop pool, which cases are worth opening, and more.

CS2 Skins

What are CS2 Cases?

Weapon cases are the main lootbox mechanic in CS2. When CS2 cases are opened, a wheel of items spins until it lands on the item you will receive. There are over 40 individual CS2 cases, and each case has its own collection of skins, plus a rare special item pool, including knives or gloves. Cases include a mix of lower-tier items and a select few high-tier items with extremely low unboxing odds (more on that later). To unbox a CS2 case, you need a case key, which you can buy from the CS2 store.

Items in CS2 cases fall into five ascending categories: Mil-Spec (blue), Restricted (purple), Classified (pink), Covert (red), and Rare Special Item (knife/gloves). Each tier has fewer skins and much rarer to unbox than the previous. All skins in CS2 cases can also be dropped in the StatTrak™ version, which tracks the number of kills you get with the weapon skin, but StatTrak skins are much rarer than the normal version.

CS2 cases are not the only way to get CS2 skins and items. There are actually a handful of ways: souvenir packages, sticker capsules, the Armory, and most recently, terminals.

How Do You Get Cases in CS2?

There is more than one way to get cases in CS2. Here are the four ways you can get CS2 cases, some of which are free, while others cost money:

Weekly Care Packages and Drops

If you have Prime in CS2, which is a 1 time purchase of $14.99, unless you purchased the game before it became free, in which case you already have Prime Status, you are eligible to receive a free weekly care package once per week upon leveling up (by gaining 5000 XP). Weekly drops always contain one case or terminal, and you can select two items from your weekly drop (unless you claim a chicken egg, which uses both of your weekly drops), so you are guaranteed to get at least one free case or terminal per week. Weekly care packages reset every Wednesday at 1:00 AM UTC, so you can time your level-up so that you get your weekly drop as soon as it resets.

Buying Cases on the Steam Market

The fastest way to get CS2 cases is to simply buy them. The safest way to do this is to buy CS2 cases on the Steam Community Market. There are thousands, often hundreds of thousands, of each CS2 case for sale on the Steam Community Market, and you can buy in large amounts and unbox them immediately.

Buying CS2 Cases from Third-Party Marketplaces

If you want to save some money when buying CS2 cases, which also makes opening them slightly more profitable, you should consider buying them from CS2 marketplaces. On CS2 marketplaces, items, including cases, are usually around 30% cheaper than the Steam Community Market. The only downside is that, because of Steam’s trade reversal update, after you receive a case from a third-party marketplace, you can’t open it until 7 days after you accept the trade.

Getting Cases from Armory Pass Rewards

The CS2 Armory also provides a way to get CS2 cases. If you have an Armory pass, you can collect Armory stars by gaining XP, and you can spend these stars to get CS2 cases from the Armory shop at a price of 2 stars per case. However, now that CS2 has mostly shifted to the terminal system with the Genesis Terminal and Dead Hand Terminal, its possible that no new cases will be added to the Armory.

Is the Rare Drop Pool Still in CS2?

No, as of January, 2026, CS2’s rare drop pool no longer exists.

If you are a seasoned CS2 veteran, you may have noticed that we didn’t mention the rare drop pool in the previous section about weekly care packages. That’s because CS2 silently removed the rare drop system at the start of 2026.

Historically, every time you got your weekly drops, there was a roughly 1% chance that you would get an older, legacy case instead of an actively dropping one. CS2 never explained how the rare drop system worked, or which cases were in the active drop pool or the rare drop pool, but nonetheless, this system was very real. Every once in a while, players would be extremely excited to find a $50 case in their weekly care package rather than the usual $0.40 case.

Community tracking and player reports have found that no rare cases have dropped since roughly January 8, 2026. This means that there’s no more 1% chance of getting a non-actively dropping case, and no way to get the 35+ legacy cases from CS:GO and early CS2 without purchasing them from the Steam Community Market or a third-party marketplace. More importantly, this means that no new supply of older cases can enter the market, so as older cases get unboxed, the supply only dwindles, causing prices to rise.

How Much Do CS2 Cases and Keys Cost?

CS2 cases vary in price, depending on the cases’ supply and demand, as well as where you buy them. Some of the cheapest cases can be purchased from third-party marketplaces for as little as $0.10, while the more expensive ones sell for over $100.

Regardless of the case price, the cost of the case key is always the same, even though each case requires its own specific key to open. Case keys cost $2.50 in the United States, though prices vary by country because of exchange rates and taxes.

The total cost of opening a case is always the case cost plus the key cost. When calculating how many cases you can open for a certain price, be sure to factor in the key cost, as many players often forget.

CS2 Case Odds and Drop Rates

CS2 cases have a set drop rate based on the item rarity tiers, and every item within a rarity is equally likely. Valve never published these odds publicly until CS:GO was released in China, and the rates were disclosed through Valve’s Chinese publishing partner, Perfect World, after China’s Ministry of Culture mandated loot-box transparency. These odds have been the same for every weapon case since then.

CS2 StatTrak Odds

Every CS2 skin dropped in a case, with the exception of gloves, can be StatTrak™, which means the skin tracks and displays the number of kills you have with the weapon. As you can see in the table above, StatTrak skins have a 10% chance of dropping, so every 1 in 10 skins is a StatTrak™.

What are the Odds of Getting a Knife From a CS2 Case?

Knives and gloves are Rare Special Items, which is the rarest item tier in CS2. They have a roughly 0.26% chance of dropping, meaning the chance of getting a knife or gloves from a case is nearly 1 in 400 (1 in 385 to be exact). The chance of getting a StatTrak™ knife is 10x rarer, or 1 in 3850, but be warned: StatTrak™ knives are not necessarily more valuable than normal knives.

Every CS2 Case (Full List)

The following table includes every CS2 case ever released, starting with the newest first. The list includes all 42 weapon cases, as well as the two terminals, though they are technically not considered weapon cases. Note that cases can be marked as either “Discontinued” or “No longer drops.” Discontinued cases were never part of the rare drop pool, meaning as soon as they left the active drop pool, the supply immediately ended, while cases that no longer drop continued to drop at a lower rate until the rare drop pool was removed in January 2026.

Best CS2 Cases to Open

There’s no single best answer, but you can figure out the best CS2 case for you to open in a few ways. Here are some of the best cases for different preferences, plus some tips for selecting the best case to open in your specific circumstances.

Maximum Volatility: CS:GO Weapon Case

If you want to risk it all for a chance at life-changing money, the CS:GO Weapon Case is for you. At a staggering $100 per case (plus the $2.50 key), this is the most expensive CS2 case out there, but for good reason. From this case, you can unbox the legendary AK-47 | Case Hardened, which, if you get a good pattern, could be worth up to $1,000,000 (though only one skin of this value has ever been unboxed after hundreds of thousands of attempts). Along with the legendary AK-47 Case Hardened Blue Gem, you can also get the iconic Karambit | Case Hardened Blue Gem, which, in Factory New condition, has been valued at over $1,500,000. Not bad for a $100 investment!

Low Risk, Low Reward: Active Drop Pool

If you want to get the thrill of opening cases without breaking the bank, we suggest opening from the active drop pool. These cases are actively dropping, so the supply is large and constantly growing, making them dirt cheap. That means you can open more cases and get more chances to unbox knives and gloves!

The Smart Bet: Check ROI

Technically speaking, the smart bet is not to bet at all. CS2 cases are not profitable, meaning in the long term, you will lose money.

That said, if you are going to open cases regardless, the smartest way to select which CS2 case to open is to use a case return on investment (ROI) tracker like CSROI.com. By checking ROI, you can see which cases have the highest average return and chance to profit, maximizing your chances of success.

Are CS2 Cases Worth Opening?

Generally speaking, no, they aren’t “worth” opening, because of the negative expected value. Cases are highly volatile, and your odds of profit are very slim, even lower than in casinos. If your goal is to get CS2 skins, you are much better off just buying them from a marketplace or the Steam Community Market. If you want to have some fun, its alright to open CS2 cases, but dont go into it with the expectation to profit, and always be responsible.

CS2 cases are not very distinguishable from gambling, and for all intensive purposes, they are essentially gambling. This makes them highly addictive, so we cannot stress enough how important it is to practice responsible gambling when opening CS2 cases. Additionally, since gambling is never advised to individuals under the age of 18, we encourage players under 18 to stay away from CS2 cases, as the risks of addiction are simply too great to be justified by any rewards.

CS2 Cases vs. Case Opening Sites

CS2 case opening sites were modeled on CS2 cases, but they differ in many ways. While CS2 cases have pretty bad ROI, CS2 case opening sites usually have better odds and a lower edge; though, as with all forms of gambling, the house always has an edge on you. CS2 case opening sites also allow different payment methods, plus reward systems like free daily cases and other bonuses. Many CS2 case opening sites also offer case battles, a game mode where you compete against other players to unbox the most value.

That said, CS2 case opening sites are just as much, if not more, a form of gambling than CS2 cases. Always exercise responsible gambling and never play on CS2 case opening sites under the age of 18.
