Site cases are not Rust crates
Cases on gambling sites have nothing to do with the crates you loot during a wipe or the skins you buy in the Rust Item Store. Each site builds its own cases: it picks a list of skins, gives every item a drop chance and sets a price. A name like "5% AK" or "70% Tempered", both of which you will see on Bandit.Camp's case grid, describes the odds of the headline item and nothing else about the case.
The skins inside are real, tradable items that entered the economy through the Item Store or Twitch drops. What the site controls is the price it puts on each one and how often it lands.
How to read a case page
Open any case and look for the item list before you look at the open button. On a decent site, each item shows its value and its drop percentage. With those two columns you can work out the case's expected value yourself: multiply each value by its chance and add the results.
Here is a made-up case with five items:
| Item (example) | Value | Drop chance | Adds to expected value |
|---|---|---|---|
| Top skin | 200 coins | 0.5% | 1.00 |
| Mid skin | 20 coins | 4.5% | 0.90 |
| Common skin A | 3 coins | 25% | 0.75 |
| Common skin B | 1.50 coins | 30% | 0.45 |
| Filler skin | 0.50 coins | 40% | 0.20 |
The expected value adds up to 3.30 coins. If this case costs 3.60 coins, you get back about 92% of the price on average, and the other 8% or so is the edge.
The more useful number is hiding in the drop column. In this example, 95% of openings give you an item worth less than the case. That is normal, because the price is propped up by a rare top drop most players never see. When you compare two cases on the same site, divide expected value by price and prefer the higher figure.
Also check that the fairness page covers cases and lets you verify an opening with its server seed, client seed and nonce. Our provably fair walkthrough covers the steps.
Where we would open cases
RustEasy. Our top-ranked site, with the strongest trust and payout scores we give (9.3 and 9.4). It withdraws in Rust skins, CS2 skins and crypto, so an unboxed item is easy to cash out in whatever form you want. Code CSGOCORN adds 5% to deposits.
RustClash. Three free cases with code CSGOCORN, plus a 5% deposit bonus. The free cases are the reason to start here: you see how the case pool behaves before your own balance is involved.
RustyLoot. $2.00 free on signup with NEWCORN. That balance goes further on cheap cases than in a battle, so it is a fair way to test how the site prices its items.
Bandit.Camp. Sixth overall, so not our first pick on trust, but its case grid is the easiest to sort. Filters for Popular, New, High risk, Low risk and Cheap let you go straight to low-variance cases instead of scrolling past the flashy ones. Its NEWCORN code gives $0.15 on signup, which is small.
RustBattle, RustReaper and RustMagic also sell cases. RustMagic's CSGOCORN code includes three free cases, and RustBattle's CORN code gives $2.00 plus three free cases, both fine for a test spin. The full list sits on our bonus codes page.
Cheap cases or expensive ones
Price changes how fast a balance moves. The share the site keeps from each coin depends on the edge. If two cases on the same site carry the same edge, ten openings of a 1-coin case and one opening of a 10-coin case cost you the same amount on average. The difference is what happens along the way.
The cheap route gives you ten results, ten chances to stop, and a much smaller swing on each click. The expensive route is one result and done. For a first session on a new site, we would always take the cheap route, because it tells you more about how the site prices its items for the same money.
What free cases are really worth
A free case is worth the case's expected value, and the headline item on the thumbnail barely moves that number. Three free cases with an expected value of 1 coin each are worth about 3 coins to you, and less once the site's conditions are applied.
Those conditions vary. Some sites credit free case winnings as locked balance until you deposit or wager a set amount. Others cap what you can withdraw from bonus winnings. Read that part of the terms before you open, since it decides whether a lucky drop is withdrawable at all. Our bonus guide goes through the usual conditions one by one.
Habits that drain a case balance
- Opening expensive cases because the thumbnail shows the rarest skin in them. Look at the drop table instead.
- Using open-five or fast-open buttons. Five openings in one click means paying the edge five times before you have looked at a single result.
- Selling every drop back to the site and reopening straight away. Each loop pays the edge again on a smaller balance.
- Sticking with a case because it "has to pay soon". Each opening is independent, and the case keeps no memory of your last twenty.
If you like the case mechanic but want an opponent, the same sites run battles, ranked on our case battle page. Upgraders are another place players take low-value drops, covered in the upgrader ranking.
Pick a budget per session before you open the first case and stop when it is gone, whatever the last one paid. Our responsible gambling page has limit tools and helplines if that stops working for you.
