Best Provably Fair CS2 Case Sites (2026)

Our top pick

We have not finished testing enough sites to rank provably fair CS2 case sites yet. We only rank a site after we deposit, trade and withdraw with our own money. This page lists the sites we are testing and how we will rank them.

Last updated

How we ranked these sites

Sites are ordered by their fairness and provably fair score, with the overall score breaking ties. A site only appears here if our testing showed it fits this use case. We only rank sites we have tested with our own money.

The weights behind every score are public on our methodology page. Affiliate deals never change a score or a position.

How to choose

A fairness page is not proof

We only list a site here after we recomputed real rolls from its revealed seeds and got the same results.

Change your client seed

Setting your own client seed means the site cannot pick a server seed that suits it. Do this before you play.

Frequently asked questions

How do I check a provably fair roll?

Copy the server seed, client seed and nonce from the site, then paste them into our provably fair verifier.

Does provably fair mean I will win?

No. It only proves results were not changed after you played. The house edge still applies.

Why does the server seed have a hash?

The hash is shown before you play so the site cannot change the seed later. After you rotate seeds, you check the revealed seed matches that hash.

Do all sites use the same formula?

No. Each site uses its own method, which is why we test each one.

What is a nonce?

A counter that goes up by one with each bet, so every roll from the same seeds is different.
